Foundation Cracks: When to Worry & Act
Owning a home is one of life’s most rewarding endeavors, but it comes with its fair share of responsibilities and concerns. Among these concerns, foundation cracks can be particularly worrisome. But how do you know when to worry or act?
Knowing the types of foundation cracks helps homeowners keep their homes strong and avoid expensive repairs. In this post, we’ll look at the types of cracks, what causes them, and when to call a professional.
Understanding Foundation and Wall Cracks
Wall cracks may present themselves in different forms, including vertical or horizontal lines running along the wall, stair-step cracks, and diagonal fractures around doors and windows. These foundation wall cracks are usually attributable to the natural shrinkage of concrete as it cures, foundation settlement, and expansive soils. However, a seemingly minor crack could also be the first sign of significant structural issues with your foundation.
Cracks that appear in your poured concrete foundation or crawl space walls, particularly those that let in water during rains, are a clear indication that your home’s foundation requires attention.
With early detection and swift intervention from our foundation crack repair specialists, you can potentially avert costly structural repairs and safeguard your home’s stability.
Types of Foundation Cracks
Recognizing the type of crack can help you determine its severity and the necessary steps to address it.
Small, Vertical Cracks
Vertical cracks often show up in foundation walls due to concrete shrinking as it cures. These cracks are usually not structural and not immediately concerning, but they should be watched and fixed to prevent more damage. If you can fit a nickel snugly into the crack, there’s no immediate cause for concern. Recheck it in six months and consult a professional if it has changed.
Horizontal Cracks
Horizontal foundation cracks are often a sign of severe complications and require immediate attention. Uneven soil and pressure push against your foundation, causing horizontal cracks in your basement wall and possibly bowing. Ignoring these signs can lead to wall collapse over time. Hire a professional foundation repair company to quickly assess and fix these cracks.
Stair-step Cracks
Stair-step cracks resemble a set of stairs, appearing in brick, stone, or concrete block walls. They often indicate differential settlement or moisture issues. Differential settlement occurs when one part of your foundation settles more than others, causing uneven stress and cracking.
These cracks are a clear indication of uneven settling in your home and could lead to additional issues like drywall cracks or nail pops. It’s important to have a thorough evaluation by foundation crack repair experts.
Diagonal Cracks
Diagonal cracks, typically seen at a 45-degree angle, suggest foundation settling or movement. Stress on the foundation corners can lead to these cracks. Monitor the angle of diagonal cracks to assess movement direction—upward indicates upward movement, while downward suggests settling. Contact a foundation repair specialist for a thorough inspection and guidance.
What Do Wall Cracks Mean?
Wall cracks, particularly foundation wall cracks, often signal a structural issue that should not be overlooked. Both visible and hidden wall cracks deserve attention as they can lead to significant, costly damage if left unchecked. Understanding what these cracks imply is critical to safeguarding the structure and health of your Memphis home.
Identifying Urgency
Determining the urgency of foundation cracks is essential to maintaining your home’s structural integrity. Not every crack is a cause for alarm, but some require immediate action. It’s always best to contact a professional for an inspection.
Using the “Quarter-inch Rule”
The “quarter-inch rule” is a helpful guideline to determine if a crack necessitates professional evaluation. Measure the width of the crack using a ruler or tape measure. If the crack is wider than a quarter of an inch, contact an expert to assess potential structural issues. Use this rule as a general indicator in conjunction with other observations.
Tools and Methods for Measuring Crack Width
Accurate measurement of crack width is crucial to understanding its severity. Use a simple ruler, crack width gauge, or calipers to measure and track changes over time. Document measurements and take photographs regularly to monitor any progression. This data will be useful for professionals assessing the situation.
