Radon gas is a silent threat in many homes, often seeping through foundations and crawl spaces. Invisible, odorless, and radioactive, it poses significant health risks, making radon a critical concern for homeowners. One potential solution is crawl space encapsulation, a process frequently recommended for improving air quality and addressing radon in crawl spaces. But can it truly help prevent radon in crawl spaces and reduce exposure to this dangerous gas?

This guide explores the connection between crawl space encapsulation and radon risks in crawl spaces. You’ll discover how radon infiltrates homes, the health risks associated with it, and whether encapsulation is an effective way to reduce or prevent radon in crawl spaces.

How Does Radon Enter Homes?

Radon is a radioactive gas that forms from the natural decay of uranium in soil. While it typically disperses harmlessly in open air, it can accumulate indoors, becoming a serious health concern. Homes with crawl spaces are especially vulnerable, as these areas provide direct pathways for radon to enter the living space.

Common Entry Points for Radon

• Exposed Soil in Crawl Spaces: Dirt or gravel floors in crawl spaces act as open gateways, allowing radon to seep directly into the home.
• Cracks in Foundation Floors and Walls: Even small cracks in foundations can allow radon to infiltrate, increasing the level of radon in your home.
• Open Crawl Space Vents: Poorly sealed or improperly installed vents can unintentionally enable radon gas to flow inside.
• Utility Penetration Points: Gaps around pipes, wires, or other utility entries provide additional access points for radon.

By understanding these entry points, homeowners can better identify radon gas reduction methods to protect their living space from harmful radon concentration.

Why Radon is a Risk Worth Addressing

Radon is more than just an inconvenience—it’s a serious health hazard. The U.S. Environmental Protection Agency (EPA) identifies radon as the second leading cause of lung cancer and the primary cause among non-smokers.

Health risks become significant when radon levels reach 4 pCi/L (picocuries per liter) or higher. Since radon is odorless and invisible, testing for radon is the only way to determine its presence and concentration in your home.

To prevent dangerous buildup, it’s essential to install a radon mitigation system if elevated levels are detected. These systems are specifically designed to reduce radon concentration and protect the health of your household. Addressing radon in your home isn’t just about safety—it’s about peace of mind.

What is Crawl Space Encapsulation?

Crawl space encapsulation involves sealing your crawl space with a durable vapor barrier, often made of polyethylene plastic. It also involves sealing all foundation walls, vents, and openings to create an air-tight environment.

Benefits of Crawl Space Encapsulation

While protection against radon is one of the most crucial benefits, encapsulation serves to:

• Control Moisture: Reduce humidity levels that contribute to mold growth and wood rot.
• Improve Air Quality: Minimize allergens like mold spores entering the home.
• Create Usable Storage Space: Make your crawl space cleaner and more accessible for storage.
• Increase Energy Efficiency: Reduce energy loss from drafts and excess moisture.

Beyond making your home more livable, crawl space encapsulation extends the lifespan of your property’s structure by reducing moisture damage.

Does Crawl Space Encapsulation Reduce Radon?

The short answer is yes, but there’s more to the story.

Crawl space encapsulation creates an initial defense by sealing off the ground and foundation walls, cutting off pathways for radon gas to enter the crawl space air. When paired with a radon mitigation crawl space system (such as a radon fan), the sealed environment becomes highly effective at reducing radon levels.

However, encapsulation alone may not lower radon to EPA-recommended levels. A radon reduction system, installed by a qualified radon mitigation contractor, is often necessary to fully vent radon outside the home and ensure a safer indoor environment.

Why Could Radon Levels Still Increase After Encapsulation?

Although encapsulation should reduce radon levels, it can occasionally result in unexpected spikes. This can happen if the crawl space was improperly sealed, leaving gaps in the barrier or leaks in the system. Reduced airflow from sealing off vents can also sometimes trap radon gases inside the space.

If radon levels rise after encapsulation, it’s essential to retest and address any deficiencies in the installation. The EPA recommends allowing several days for radon levels to stabilize post-encapsulation and utilizing a mitigation system if needed.

Crawl spaces might not be the most glamorous part of your home, but they are essential for protecting the structural integrity of your home and improving indoor air quality. Many homeowners wonder—Is crawl space encapsulation really necessary? The answer depends on factors like the age of your home, your location, and specific challenges you might face, such as moisture buildup or deteriorating crawl space walls.

Encapsulation involves sealing and insulating these areas to prevent issues like mold, pests, and structural damage. It’s a smart investment that not only helps preserve the health of your home but also creates a cleaner, healthier living environment. This guide will delve into the process of crawl space encapsulation, its benefits, when it’s necessary, and how experts like DFX Foundation & Waterproofing Experts can ensure the job is done right.

What is a Crawl Space?

A crawl space is a shallow area beneath a home that elevates it from the ground, often providing access to plumbing, electrical wiring, and ventilation systems. However, these spaces are prone to various issues, including:

• Moisture Accumulation: Exposed soil or poor drainage on your crawl space floor creates a damp environment, leading to condensation.
• Mold Growth: Excess moisture creates a breeding ground for mold and mildew.
• Pest Infestation: Dark, damp crawl spaces attract insects, critters, and rodents.
• Structural Damage: Persistent dampness can weaken support beams and joists, causing costly structural issues.

Left unchecked, these problems can compromise indoor air quality and even the safety of your home.

What is Crawl Space Encapsulation?

Crawl space encapsulation is a protective solution designed to seal off your crawl space from moisture and outside elements. The process typically includes:

1. Sealing Vents and Openings – Prevents external air, pests, and water from entering.
2. Installing a Vapor Barrier – A thick, durable plastic sheet (often 20-mil polyethylene) is laid down to cover the soil and walls, minimizing moisture migration.
3. Adding Insulation – Rigid spray foam or other high-quality insulation materials improve thermal resistance.
4. Installing a Dehumidifier – Regulates humidity levels within the space for long-term moisture control.

This process transforms your crawl space into a clean, dry, and controlled environment, protecting it from the common issues associated with exposed crawl spaces. In some cases, drainage solutions and a crawl space sump pump may be necessary to manage excess moisture and ensure long-term protection against water damage.

Benefits of Crawl Space Encapsulation

Why should you consider crawl space encapsulation? Here are the top benefits it offers for homeowners:

1. Improved Air Quality

Encapsulation helps prevent allergens, mold, and mildew from spreading from your crawl space into your home’s living areas. This is particularly important for households with members who suffer from asthma, allergies, or respiratory conditions.

2. Energy Efficiency

Sealing your crawl space helps minimize drafts and energy loss, allowing your HVAC system to run more efficiently. By maintaining a stable indoor temperature, encapsulation can significantly reduce your heating and cooling expenses.

3. Pest Protection

Sealing your crawl space closes gaps where pests and rodents typically enter, keeping your home free from unwanted visitors.

4. Structural Protection

Controlled moisture levels prevent wood rot and warping, extending the lifespan of your home’s support structures.

5. Better Home Value

Buyers love the assurance of a well-maintained home. An encapsulated crawl space signals care and attention, which can enhance your property’s resale value.

6. Peace of Mind

No more worrying about foul odors, sagging floors, or hidden damage beneath your home. Encapsulation helps eliminate these concerns, offering a safer and more pleasant living environment.

Is Encapsulation of Your Crawl Space Necessary?

The necessity of crawl space encapsulation depends on a variety of factors.

Key Indicators to Watch For:

• Are there signs of moisture problems, such as condensation or mold?
• Have your utility bills spiked due to an inefficient HVAC system?
• Is your home prone to recurring pest infestations?
• Do you notice a musty smell seeping up from your floors?

If you answered yes to any of these questions, crawl space encapsulation might be the solution to these persistent issues.

Older Homes

Older homes often have a history of long-term moisture exposure. While encapsulating the crawl space can preserve and protect what remains, any existing damage must be assessed and repaired first.

Climate Considerations

If you live in areas with high humidity or heavy rainfall (like Tennessee, Arkansas, or Mississippi), crawl space encapsulation is especially beneficial to combat environmental conditions that exacerbate moisture problems.

Common Misconceptions

Some homeowners believe venting is enough to address moisture, but research reveals that sealed crawl spaces, combined with dehumidification, are more effective for maintaining healthy environments. Encapsulation debunks the outdated “ventilation myth” by creating a controlled, sealed environment.

How Does the Encapsulation Process Work?

Professional crawl space encapsulation involves several steps:

• Step 1: Clean and inspect the crawl space, addressing any existing mold, pests, or structural issues.
• Step 2: Apply high-quality vapor barriers, ensuring the material is thick and durable (20-mil is often the standard). Barriers are sealed at all seams and around piers.
• Step 3: Add insulation with an appropriate R-value (R-10 or higher).
• Step 4: Install a dehumidifier to maintain optimal humidity.
• Step 5: Ensure vents and gaps are sealed to prevent external elements from entering.

When it comes to investing in your home, some upgrades, like a sparkling new kitchen or a luxurious bathroom, are obvious choices. But there’s one often-overlooked improvement that can significantly boost your home’s value, efficiency, and safety—crawl space encapsulation. This hidden gem of a renovation tackles moisture problems, enhances energy efficiency, and even helps protect against pests, making it one of the smartest crawl space improvements you can make.

Crawl space encapsulation isn’t the flashiest home upgrade, but it’s one of the most effective. By sealing off your crawl space, you’re not only protecting your home from moisture and damage but also increasing its resale value. Encapsulated crawl spaces are becoming a sought-after feature for homebuyers, as they deliver long-term benefits like better air quality, lower energy costs, and a safer, healthier living environment.

But what exactly is crawl space encapsulation, and is it worth the investment? In this blog, we’ll explore everything you need to know—how it works, the key benefits, and why addressing moisture problems with crawl space improvements could be one of the best decisions for your home’s long-term value.

What Does It Mean to Encapsulate a Crawl Space?

Encapsulation is the process of sealing a home’s crawl space with a durable vapor barrier, along with additional measures like insulation and dehumidifiers. Essentially, it turns an open, potentially troublesome area under your home into a clean, controlled, and sealed space.

Typically, crawl spaces without encapsulation are prone to dampness, dirt, mold, and even pest infestations—all of which can negatively impact the health and structural integrity of a home. By encapsulating this area, you create a barrier that prevents moisture and pests from wreaking havoc while also improving energy efficiency.

Components of Crawl Space Encapsulation:

• Vapor Barrier: A thick plastic layer that seals the floors and walls of the crawl space to block moisture.
• Drainage Solutions: For homes with high water levels, a drainage system may be installed.
• Sump Pump Installation: Helps remove excess water to keep the crawl space dry.
• Dehumidifier: Maintains a dry environment to further prevent mold growth and water damage.

Now that we’ve demystified the process, let’s explore how this upgrade could be a win-win for homeowners and homebuyers alike.

5 Benefits of Crawl Space Encapsulation

1. Improves Energy Efficiency

Did you know a drafty crawl space can drive up your energy bills? Open crawl spaces allow outside air to circulate freely, making it harder for your home’s HVAC system to maintain a stable indoor temperature. Sealing off this area keeps your home better insulated and helps minimize energy waste.

Encapsulation has the potential to reduce heating and cooling costs by up to 20%, which translates into significant savings over time. According to the EPA, every $1 saved in energy boosts your home’s resale value by $20 to $24. Imagine how this efficiency can further attract cost-conscious buyers when it’s time to sell.

2. Enhances Indoor Air Quality

Crawl spaces aren’t just structural elements; they also have a direct impact on the air you breathe. Up to 50% of the air inside the first floor of your home can originate from the crawl space. If this space is full of mold, pests, and moisture, those contaminants may circulate through your living areas, leading to musty odors and potential health concerns such as allergies or respiratory issues.

Encapsulation prevents these pollutants from entering your living space, resulting in noticeably cleaner and healthier indoor air. This benefit is especially appealing to families with young children or individuals with allergies.

3. Prevents Water Damage

Excess moisture is a crawl space’s worst enemy. It can lead to wood rot, weaken your home’s foundation, and encourage mold growth. Water damage repairs can cost thousands of dollars, while severe cases involving foundation issues can cost even more.

Encapsulation tackles this problem head-on by creating a moisture barrier that stops water intrusion before it starts. This proactive approach ensures your home remains structurally sound and free from costly water-related repairs.

4. Discourages Pest Infestations

Crawl spaces provide the perfect hideout for pests like rodents, termites, and insects. Left unchecked, these invaders can damage insulation, chew through wires, and compromise the structure of your home.

By encapsulating the crawl space, you effectively eliminate the dark, damp environment that pests thrive in. This added layer of protection can also save you from the inconvenience and expense of pest control services.

5. Reduces Maintenance Costs

Unsealed crawl spaces often require constant maintenance to address mold, water damage, and pest problems. These recurring expenses can take a toll on your time and wallet.

Encapsulation significantly reduces the need for regular upkeep, giving you greater peace of mind. With less to worry about, you can focus on enjoying your home rather than constantly managing repairs.

How Crawl Space Encapsulation Adds Value to Your Home

For many homeowners, the decision to invest in crawl space encapsulation comes down to dollars and sense. Can the money spent on this project actually increase your home’s resale value?

The answer is yes. Homes with encapsulated crawl spaces are generally more appealing to buyers because they’re safer, healthier, and more energy-efficient. Prospective buyers appreciate knowing they won’t inherit issues like water damage, mold, or high energy bills.

Energy-efficient home upgrades can yield a significant return on investment (ROI), and crawl space encapsulation falls within this category. Additionally, the long-term cost savings and reduced risk of major repairs make these homes more attractive even in competitive markets.

Is Crawl Space Encapsulation Worth the Investment?

Cost Breakdown:

The cost to encapsulate a crawl space varies depending on its size, condition, and location. While exact costs vary, many homeowners find the benefits outweigh the expense.

For example:

• Homes with encapsulated crawl spaces may sell for up to 10% more than similar homes without this feature.
• The energy savings can help recoup the investment over time, especially for homeowners who plan to stay in their homes long term.

Factors to Consider:

1. Climate: Encapsulation is particularly beneficial in humid or flood-prone areas where moisture control is critical.
2. Property Age: Older homes with outdated crawl spaces may see the biggest gains in value and efficiency.
3. Health Benefits: If you or your family members struggle with allergies or asthma, the improved air quality could provide invaluable peace of mind.

What’s Next? Make Your Space a Selling Point

Looking to protect your home while boosting its value? Crawl space encapsulation is a smart upgrade that delivers more than just financial benefits. This process not only enhances your home resale value by addressing key concerns like crawl space floors, structural damage, and pests, but it also improves indoor air quality for a healthier, more comfortable living environment.

When it’s time to sell, having a properly encapsulated crawl space becomes a unique selling point that sets your home apart. The encapsulation real estate impact is clear—buyers value homes that are protected from moisture, rodents, and insects, all while offering improved energy efficiency.

It is vitally important to understand the importance of crawl space encapsulation, identify and address wall cracks in your foundation, and use a step-by-step guide to wall crack repair in order to reap the many benefits of crawl space encapsulation for the health of your home’s foundation.

Understanding the Importance of Crawl Space Encapsulation

Crawl space encapsulation is an important part of keeping a home healthy and safe. It is the process of creating an air-tight seal between a home’s walls and floors, with the intent of isolating the moist, dark, and humid conditions of a crawl space from the rest of the house. Through this process, mold growth, water damage, and other detrimental elements can be prevented or mitigated. The overall energy efficiency of the home is improved, since outside air is not allowed to seep through the floorboards, walls, and other small spaces.

The process of encapsulating a crawl space is not a one-size-fits-all solution. Homeowners must first assess the condition of the existing environment and determine if it is suitable for encapsulation. For instance, an area that has already seen significant water leakage or mold growth will not be a good fit for encapsulation. Similarly, a home with a poorly constructed foundation, or one located in a location with frequent flooding, is also not ideal. As a result, homeowners must evaluate the space carefully before opting for encapsulation.

Once a homeowner has decided to encapsulate their crawl space they must also decide on the materials to use. Generally, this involves choosing a heavy-duty plastic vapor barrier, as well as insulation and sealing materials to complete the airtight seal. Other factors, such as proper drainage systems, ventilation, and dehumidification systems, may also need to be installed to ensure the optimal functioning of the crawl space. Consequently, it is important that homeowners familiarize themselves with the available options and research their choices carefully before committing to any material or product.

Crawl space encapsulation is an important part of keeping a home healthy and safe. It can provide significant energy savings and prevent damage caused by mold, moisture, and water leakage. However, it is important for homeowners to understand the process involved in encapsulation and to properly assess and prepare their environment before taking the steps toward encapsulation.

Identifying and Addressing Wall Cracks in Your Foundation

Identifying and addressing wall cracks in your foundation are an important part of home maintenance. It is essential to properly inspect your foundation and identify any potential wall cracks. Doing so can help prevent any further damage and costly repairs.

However, there are various types of foundation cracks, so it is important to be able to identify them. Hairline cracks usually run horizontally along the wall and are typically very thin. These cracks should be monitored over time as they may require minimal repair. On the other hand, stair-step cracks are larger, more serious cracks that usually appear on outside masonry walls and indicate the wall is shifting outward. Displacement cracks are similar to stair-step cracks, but are characterized by their unusually wavy pattern.

In addition, for each type of foundation crack, there is a specific repair method. Generally, minor hairline cracks can be filled with epoxy or latex caulk, however for more serious cracks, partial or full wall replacements may be needed. A foundation contractor can evaluate the damage and determine the best course of action, which may include parging or beam replacement. For instance, if the beam is out of place and compromises the stability of the wall, the contractor may need to replace the beam to restore the structure.

Similarly, wall and foundation cracks can be prevented with proper maintenance. Primarily, it is important to check for visible signs of wear and tear, and monitor seasonal changes in your foundation’s condition. As a result, you should ensure that your foundation is adequately protected from excessive water or snow. This can be done through proper landscaping, installing drainage systems, and waterproofing the walls. Taking precautions to prevent foundation damage can help avoid future costly repairs.

The Step-by-Step Guide to Wall Crack Repair

Cracks in the walls of any home or other property can be an unsightly and potentially damaging sight. If not caught and corrected in time, it could end up costing thousands of dollars in repairs. Fortunately, repairing wall cracks can be relatively straightforward and cost-effective if the homeowner knows how to do it. Here is a step-by-step guide to wall crack repair.

Firstly, it is important to assess the severity of the crack and take action as soon as possible. Carefully examine the wall and determine if the crack is horizontal or vertical. Horizontal cracks are usually more serious and will require more intensive repair. Inspect the walls around the crack for any signs of water damage which could indicate a more serious structural issue.

Once the severity of the crack is determined, the homeowner should prepare the area for repair. This involves cleaning the area of dust and debris and ensuring the wall is dry. Making sure the area is dry is essential, as any moisture left behind could cause further damage.

In addition, the homeowner should apply a patching compound and spread it evenly across the crack. There are several different materials available for this task, such as drywall mud or mortar, and it can often make the difference between a safe and secure repair job and a poorly done one. Smooth the patching compound into the crack with a putty knife and allow it to dry.

For instance, the homeowner should then use some kind of tape to reinforce the patching compound. Commonly, fiberglass mesh tape is used, as it is a strong and flexible material. Place the tape over the patching compound and use drywall compound to smooth it out ensuring that the tape does not protrude from the wall. Coated mesh tape, which is self-adhesive, is another alternative.

Finally, the homeowner should apply one or two coats of paint to the wall. This will not only improve the aesthetic appeal of the wall, but will also seal and protect the patched area form further damage.

Therefore, most wall cracks can be easily and quickly repaired by a homeowner if they follow the correct process. Taking the time to assess the severity of the crack, prepare the area properly, use the correct patching materials, and finish with a protective coat of paint will result in a safe and secure repair.

Benefits of Crawl Space Encapsulation for Your Home’s Foundation

Crawl space encapsulation offers numerous benefits for the home’s foundation. It helps reduce the levels of moisture and humidity as well as air flow, which can prevent any possible damage from pests or molds. It keeps the home’s foundation insulated against extreme temperatures and can help to reduce energy costs. On the other hand, it also provides for an effective barrier and can improve the overall structural integrity of the home’s foundation. Furthermore, any possible health risks can be greatly reduced thanks to crawl space encapsulation’s ability to limit the growth of hazardous molds.

In addition, crawl space encapsulation provides for much better air quality and helps to eliminate odors that can be caused by excess moisture in the crawl space. Similarly, it helps make crawl spaces more habitable as they can be used for storage effectively. As a result, the homeowner will not need to clear out the space every few months. Crawl space encapsulation provides numerous benefits for the home’s foundation, including improved structural integrity, improved air quality, and more livable crawl spaces.

Frequently Asked Questions

What is crawl space encapsulation and why is it essential for foundation protection?

Crawl space encapsulation is the process of sealing off the crawl space environment from the outside air. It involves various steps such as sealing off the walls, floor and vents to prevent air circulation; installing a vapor barrier; installing drainage and insulation; and ventilation systems. This helps prevent moisture from entering the foundation, which can cause foundation cracking and settlement. It also helps reduce noise, decrease energy costs, and improve indoor air quality. Furthermore, it can help protect against mold, mildew, and other airborne allergens.

How can I detect and assess wall cracks in my home’s foundation?

To detect and assess wall cracks in your home’s foundation, the best thing to do is hire a professional home inspector to conduct a thorough assessment of your foundation. A home inspector can inspect your foundation and assess the condition of your walls, checking for any cracks, fractures, or other signs of damage or structural deficiencies. They can also recommend any necessary repairs. Additionally, if you are concerned about potential wall cracks, you can also look for signs of settling or shifting such as windows or doors that stick, sloping floors, gaps at the corners of windows or doors, or damage to the walls or floor that could indicate foundation issues.

What are the common causes of wall cracks in foundations?

Common causes of wall cracks in foundations include:

1) Improper compaction of soil around the foundation when it was built
2) Improper drainage leading to hydrostatic pressure building up against the foundation
3) Temperature fluctuations that cause the foundation to expand and contract
4) Poor initial construction or use of low-quality materials
5) Settling and shifting of the soil beneath the foundation due to changes in moisture levels or a shifting water table.

What are the key steps involved in repairing wall cracks in a foundation?

1. Identify the type of crack: Examine the cracks in detail and determine whether they are structural cracks or cosmetic cracks. Structural cracks need to be repaired first as these indicate some underlying issue with the foundation.

2. Repair decorative cracks: If the cracks are cosmetic, they can be filled with a latex caulk made for foundation-repair applications or a two-part epoxy.

3. Repair structural cracks: Structural cracks can present a much larger problem, as they may indicate a shifting in the foundation or a problem with the soil. A professional foundation repair team should be called in to identify the source of the problem and to fix the cracks.

4. Monitor for further issues: Even after the cracks have been repaired, it is important to monitor them for any further signs of movement or damage. If any of these conditions appear to worsen or further foundation repairs need to be made, contact a professional for additional evaluations.

Initial Signs: Stinky Home, Cracks, and Moisture

You’ve noticed that your home is stinky, cracks in your home, or moisture inside your crawl space. You contact a crawl space foundation repair specialist and they recommend crawl space encapsulation to fix your home’s mold, moisture, & settling issues that is occurring in your crawl space.

At this point, many people have different reactions, questions, and opinions. Some may question “Did our foundation specialist oversell our problem just to get another job?” Others may wonder, “My home has been here for decades; will my cracks, musty smell, or moisture REALLY get any worse than what it is now?” And others may think, “that problem seems too expensive to fix, I’ll just sell the home and let someone else deal with it!”

Our Philosophy at DFX Foundation & Waterproofing Experts: No Scare Tactics

At DFX Foundation & Waterproofing Experts we do not use any high-pressure sales tactics or scare tactics to try to win a job or sell you on work you do not need! Unfortunately, not all companies have the same mindset. We have run into countless customers that felt over pressured in the past by other foundation specialists or we have found that they were oversold on what their home needed to be stabilized & moisture-free. Our motto is the same, we create customized solutions for customers to FIX their homes. We don’t try to sell what will not benefit your home.

At DFX Foundation & Waterproofing Experts we also recognize that every customer’s situation is not the same. We take this into consideration when designing our repair plans and options for our customers to help suit their future home plans so that we can benefit & accommodate our customers as much as possible.

Risks of Ignoring Crawl Space Issues: Why Encapsulate Now

Many people who have noticed moisture issues & foundation issues in their crawl space received a quote for a crawl space encapsulation and deferred getting any work completed. Often the mindset is, “it hasn’t been a problem for decades, it shouldn’t get any worse.” However, home moisture issues are not just ‘rinse & repeat’ – they are cumulative. Meaning that every time your home is flooded or is exposed to excessive moisture in the crawlspace, it is attacking your home.

The Consequences of Deferred Encapsulation

Moisture in the soil will continue to cause your foundation footer and piers to settle, resulting in more cracks in your home. Moisture in the soil and your crawl space vapor space will continue to fuel mold growth. Obviously, the mold growth is terrible for your health as at least 50% of your home’s indoor air is from the crawl space.

Unfortunately, we have completed way too many jobs that were previously identified but deferred for an extended period of time. The more damage that progresses means to more expensive the job will be. On average, these customers could have saved 15-25% on their repair plans by not deferring fixing the problem. In some cases, we have even seen 100+% increased costs due to the damage that has occurred and increased scope requirement. Simply put, foundation & crawl space moisture problems can only get worse if you do nothing.

The Impact on Real Estate Deals: Encapsulate Before Selling

Many clients think about just passing the problem onto the next homeowner, thinking their crawl space moisture issues will go unnoticed. However, we provide many quotes to clients during a real estate deal because the buyer’s inspector has found crawl space moisture issues and foundation settling. This adds a lot of stress and anxiety to a real estate deal.

The Reality of Encapsulation: Pay Now or Pay More Later

Often, people don’t want to buy a house if it has existing crawl space moisture issues – unless they are getting a major discount on the home purchase price (usually much greater than what it costs to fix because the uncertainty for the buyer to fix after closing). The other scenario that plays out is the seller having to get a crawl space encapsulation (and/or any other required repair scope) completed before the buyer will close on the home. This adds a lot of stress to buyers and sellers due to the timing, coordination, and agreements required to align for a successful closing.

Our Promise: Peace of Mind with Encapsulation

Unfortunately, with crawl space moisture problems and home foundation problems, you can either ‘pay it now, or pay even more later.

DFX Foundation & Waterproofing Experts provides solutions to fix your home and backs it with our industry-leading warranties. Our solutions give you peace of mind by making your home solid for decades to come, increasing your home’s value, and reducing the stress and anxiety if you ever decide to sell your home.

This article offers helpful information on crawl space encapsulation. We’ll explain encapsulation, offer tips for DIY crawl space encapsulation, and explain how to maintain a healthy humidity in your crawl space.

What Is Crawl Space Encapsulation?

Encapsulating, or at least sealing, crawl spaces is a popular solution for avoiding indoor moisture issues. Encapsulation can be compared to the lining added to swimming pools to avoid leaks.

A heavy-duty polyethylene barrier is added to completely cover your crawl space – usually the floors, foundation walls, and sometimes even ceiling.

Why Encapsulate Crawl Spaces

Since up to 50% of household air can flow up from your crawl space, it’s important to keep it as clean and dry as possible. Adding a crawl space vapor barrier and dehumidifier is widely accepted as the best way to improve indoor air quality and make energy improvements inside your home.

Water vapor enters the crawl space from the ground (even through cement), leading many people to encapsulate their crawl space to keep the moisture out.

Benefits of Creating a Vapor Barrier

• Improved air quality in your crawl space and home
• Creates inhospitable area for pests and wood-destroying insects
• Allows for more comfortable living conditions
• Avoid fungi/mold issues and structural damage
• Greater energy efficiency in your home
