Why You Shouldn’t Ignore Foundation Cracks
You might be unsure of how concerning it is to see cracks in your home’s foundation. After all, a crack does not automatically indicate that you have major structural problems. Although this might be the case, you shouldn’t fully disregard foundation cracks since they might be a sign that foundation and basement or crawlspace repair is necessary.
Most Common Causes of Foundation Cracks
- Poor drainage around the foundation. Water is the cause of most foundation issues. It’s a formula for disaster if there’s too much or too little of it in the soil around your foundation. Hydrostatic pressure can build up in the earth and press against foundation walls due to poor drainage around the foundation. The walls will soon begin to bow inward and crack if the strain is not eased.
- Expansive soil. There’s a lot of clay in this soil. It poses construction issues since it absorbs a lot of moisture and then shrinks by the same amount as it dries out. Soil movement occurs as a result, which might lead to structural issues.
- Weather changes. A house built during the dry season on top of expanding soil is one example of this. When the rainy season approaches, the soil swells dramatically, causing damage to the foundation of the house.
- Soil creep. Over time, soil creep can cause foundation difficulties in homes built on slopes. When the soil from the top of a hill ultimately makes its way down the hill, this is what happens. A foundation can shift laterally due to soil creep.
- Soil that wasn’t adequately compacted before construction. If the soil underneath the house wasn’t properly compacted before construction, then the heavy structure on top can unevenly sink into the ground. This will cause foundation damage.
When we talk about foundation cracks, we’re talking about cracks in poured concrete walls and concrete block foundation walls. This does not include drywall or plaster cracks because those don’t pose an immediate threat to a building’s structural stability—they’re just unattractive. The majority of structural foundation cracks are caused by differential settling.
Some foundation cracks are severe, while others are not. These are referred to as structural and non-structural cracks. Foundation movement causes structural fissures, which, if not fixed quickly, might jeopardize a building’s structural stability. Concrete shrinkage during the curing process causes non-structural fissures, which do not jeopardize a building’s structural integrity. Non-structural cracks, on the other hand, are not innocuous. Non-structural vertical basement wall fissures, for example, can allow water to seep through.
When You Should Be Concerned
It’s time to call a professional when you see:
- Cracks that are larger than a tenth of an inch.
- Cracks that are wider on one end than the other.
- Cracks that are widening with the passage of time.
- Brickwork fractures on stair treads.
- Horizontal fissures in the foundation, with or without bowing.
- Several vertical fissures in close proximity.
- Cracks that run diagonally.
- Cracks that go from the ceiling to the wall.
- If you notice any of the above, you should schedule a foundation inspection with an expert foundation repair contractor. Don’t hesitate to call because the longer you wait, the more costly the repairs will be.

Why You Shouldn’t Ignore Foundation Cracks & the Importance of Ongoing Monitoring
Every crack in your foundation will enlarge if you ignore it, and no, you can’t simply plug the crack with more concrete. Once a crack has developed, it must be expertly sealed because as the problem worsens, so do the repair costs. Prevention, early detection, and swift action can ensure that you are not on the hook for costly repairs or devastating destruction to your home and personal belongings.
Foundation cracks lead to leaks. If you have even a small leak, mold and mildew can thrive in your basement or crawlspace. You already know that mold and mildew can be harmful, especially if they turn into black mold. You should contact us right away if you discover any leaks or moisture in your basement since mold and mildew can have major negative effects on your health.
In addition to inviting mold and mildew growth into your home, foundation cracks can lead to moisture intrusion and puddling or standing water. If neglected long term, these problems can grow into flooding and, in time, lower your home’s property value due to the destruction caused to the home’s structure.
If your home has a basement or crawlspace, it is imperative to make sure you have a moisture management professional monitoring it year round to minimize potential repairs. This is the most effective way of protecting your health and home value. Unfinished or unsealed basements and crawlspaces can be difficult to maintain, however with the right level of monitoring many repairs can be minimized, and quite often avoided.
