Foundation Repair questions, answered by experts

Yes, it is normal for a block foundation to crack. Some block foundation cracks are more serious than others and indicative of a larger structural problem. On the other hand, minor cracks may not be of immediate concern but should be monitored. Regardless, foundational cracks are not an uncommon response to wear on a structure from time and weather.

Homeowners insurance doesn’t usually cover a sinking foundation. While insurance will cover some kinds of foundation damage, coverage is usually limited to damage from natural disasters, fire, or impact. Foundation sinking is rarely covered by insurance, so it’s a good idea to make repairs early on to avoid costly problems in the future.

Cracked tiles can mean foundation problems. Fortunately, most of the time, cracked tiles happen as a result of accidental damage. It is important to determine the cause of cracking to rule out underlying foundation issues. If your tiles were not damaged due to dropped items, heavy loads, poor installation, or inferior tile quality, and the cracks are spreading throughout your flooring and not limited to just one area, you may be dealing with foundation problems. These can include drainage problems and even foundation failure, so it is vital to call a licensed contractor to assess the issue and ensure your foundation is safe.

It’s crucial to hire a foundation company that’s professional, experienced, and reliable, starting by choosing local experts with at least five to ten years of experience with your type of project. Local foundation companies will understand the soil and weather conditions in your area and can carry out the best solution based on your property characteristics. You should ask for a list of customer references, read through online reviews, and check for customer complaints and unresolved issues filed with the Better Business Bureau (BBB) before hiring.

You can patch minor cracks and damage yourself using concrete fillers or mortar. Larger damage may require full replacement of affected slabs. However, water damage to your concrete will never disappear unless you address the root cause causing the water to cumulate. To prevent future damage, you can also waterproof your concrete.
