"This was a very involved plaster repair and remediation job, in a very old house. Grady is the only person (or company) who was willing to take on the job and drive all the way from Pennsylvania to our home in Northern Virginia. There are very few people who do this kind of work anymore (we really searched) and he is an expert in his field. We needed to work around his schedule, because he is in demand in the tri-state area, so it took awhile to schedule the work to begin... but it was worth it."

"Ryan proved to be a professional in every way. His gave a fair and what I felt was an on-point quote and was here when he said he would be. My front porch was cracked, caving in and separating from the house, so the present slab had to be removed and the railings around the porch as well. He was through and completely in tune with what we discussed. The whole job was done and complete in 5 days- that included curing and set up time with cement drying. Yes, I would use Ryan again and we are already discussing the next project. I found Ryan on Angi website and I am very happy he was available to do the project. Thank you Ryan!!!!"

Foundation Repair FAQs, answered by experts

The actual foundation repair costs will depend on the extent of the damage, how many blocks you need, labor costs, and material costs. As an estimate, the average repair costs for a cinder block foundation fall between $350 and $25,000. Because the range is so large, it’s important to call a professional foundation repair company and have them assess the damage and estimate the repair costs.

The best solution to fix a foundation crack in your basement floor depends on the underlying cause. If you just have hairline cracks from settlements that are no longer growing, the best option is to seal them with a crack sealant. If the cracks continue to grow, one edge rises above the other, or there are signs that water is getting in through the crack, a professional repair will be necessary. Depending on the root cause, your professional may employ foundation underpinning or some other type of stabilization, seal the cracks, or install a drainage system.

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.

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.

Addressing gaps and cracks reduces heat loss and improves energy use.
