"Let me start by telling you my backstory. I live in a house built in 1929, it has a stone foundation. It wasn't until Hurricane Sandy that I felt the effects of a house that had no waterproofing and we had about three feet of water. We did a little bit of mitigation, and had no more problems for awhile. More recently, NY had five days of non stop rain and the walls in basement and flooring barely held it together. So that's when I knew I really had to do something. Every time we heard the weather report we would keep checking that basement and our little water pump. The water pump did ok, but we had wet vacs and worked like a team, but the water was coming up through the floors. Just a little 2-3 inches can cause so much damage. This is climate change, a lot of my friends were suffering from flooding for the first time and it wasn't going to get any better. So that was it, my husband and I interviewed four different places. They were all professional, but there was something about the detailed 2 hour interview that Scott Cort, one of their top inspectors did with us and we knew that was the place we were going to deal with. Plus he dealt with a multitude of questions from my husband and didn't flinch. He was patient, showed us exactly what they would do to protect the basement from flooding. He saw how stressed I was and just plain tired of this. It was a very comprehensive plan. Scott explained the lifetime warranty. The system is self-cleaning and requires zero maintenance. There is also a clog free guarantee. It included a PITBOSS waterpump with a wifi system and a backup battery in case the power goes out. He also told me that there would be very little dust. And there was very little dust. It only took two full days of his crew working nonstop. I was a bit nervous about cutting the walls, but he picked up the phone every time I called. If he was busy, he texted me right away and got back to me in 30 minutes. (And I call a lot). I am happy with the results. My contractor checked it out and said American Dry did a great job after dropping by to see the results. And most of all, we can sleep when it rains. We are ready!!! By the way, I have never written a review this long, but I needed to shout them out, and it was competitively priced!! Thank you AmericanDry, thank you Scott Cort. It was a pleasure!"

"John and his team did a great job. We contacted them to fix concrete steps in our back yard leading to our deck and he was able to provide all options for replacement, costing and timing. He was very respectful of when we wanted to get the project done and I felt like he knew exactly what needed to be done. I would highly recommend John and his team to anybody who needs masonry work."

Foundation Repair FAQs, answered by experts

Not all cracks in brick indicate foundation problems. For instance, small hairline cracks can occur as a new construction settles. However, larger cracks are often a sign of a more severe issue. Indicators of a potential foundation problem include long horizontal cracks, "stair-step" cracks, vertical cracks that appear indoors, or any crack that widens at the top. Other signs of structural damage to look for are uneven floors and doors or windows that stick. These issues could be caused by problems with the soil beneath the home or an overgrown tree.

Yes, you can fill cracks in concrete if you’re a somewhat handy homeowner. It’s important to know which concrete patching method to use, as small cracks require different approaches than large ones. It might seem challenging to determine which product to use and the tools necessary for the project, but with a bit of background, homeowners can restore their cracked concrete easily.

Regularly inspecting your foundation—at least the visible sections—for signs of foundation issues like moisture and pest infestation is a good way to identify slab leaks early, as is keeping an eye and ear out for water damage to indoor building materials, above-average water bills, sounds of running water when no fixtures or appliances are on, and indoor humidity that causes the temperatures to feel more extreme. If you do find any issues, contact a plumber right away to check it out for you.

Generally, foundation cracks and repair are not covered by standard homeowners insurance policies. This type of damage is often considered normal wear and tear or a result of poor maintenance, which is the homeowner's responsibility. For example, damage caused by settling, shifting soil, or drainage issues is typically excluded.

However, there are exceptions. Coverage may apply if the foundation damage is a direct result of a covered peril, such as a house fire, a burst pipe, vandalism, or a vehicle accident. Coverage for natural disasters like earthquakes and floods often requires a separate, specific policy or add-on.

The foundation repair that will work best varies based on the extent of the damage, the underlying cause, soil conditions, weather conditions, and more. Permanent foundation solutions like underpinning and exterior drainage solutions are better than temporary fixes that don’t address the source of the issue. Some examples of more temporary solutions include mudjacking or slabjacking, waterproof paint, and dampproofing. The best course of action is to have a reliable foundation specialist inspect your issue, treat the underlying problem, and restabilize your foundation.
