"this is the 4th project that I have used Foundation Recovery Systems for to repair my basement walls and the work is always spot on. On this project it was more wall anchors and Devon Brown and his crew did excellent work and were very informative about the work they were doing. They drove on very icy roads for three to four hours to get to my home."

"They were responsive to every call, did the work professionally and cleaned up nicely.  We would not hesitate to recommend them to friends and family.  We had two leaning columns in the back yard that are now straight and piered so they will never shift again.  They then removed a large area of cracked cement and relayed.  It looks fantastic!

"They did an excellent job on repairing the foundation and it stopped the leak. The sidewalk they tried to lift with foam did not do so well. To their credit, they are coming back to make it right and they are going to replace the sidewalk. They even went above and beyond and because of that, we would definitely recommend them."

"I had a great experience with Dry Basement. The estimator Curtis was extremely knowledgeable, clean cut, friendly, and straight forward. He arrived right on time and got to work. He reviewed my situation with laser measuring equipment and had a written estimate for me on the spot. We agreed on a price for the work and scheduled my repair for their next available slot, three weeks later, on December 11, 2014. I received a call from their office staff two days before the scheduled work, to remind me of my appointment and their estimated arrival time. The crew of four guys showed up right on time and got straight to work. The foreman, Alvin, was great and worked just as hard as every other guy on the crew, and these were about the hardest working guys I've ever seen in my life. Everyone was super friendly (my Labrador retriever vetted each of them and approved). It was a wet, sloppy day outside, and they put plastic down on my carpeted floors and stairs to keep things tidy. They installed 10 u-channel braces in the basement to shore up my slightly bowing foundation (just under 2" of inward bowing), and secured it to 8 yards of concrete - that's 32,000 pounds worth - in the yard. The cracks inside were sealed with polyurethane. They finished the job in one day, as promised, and cleaned everything up when they were done. In fact my basement was cleaner when they left than when they showed up. I would definitely hire these guys again, though I don't plan on having to, since from the looks of things this house isn't going anywhere. HIGHLY recommended."

Foundation Repair FAQs, answered by experts

No, house settling is normal as your home’s foundation settles into the soil below and as the framing of your home shifts as it expands and contracts with changes in temperature and moisture. However, if you get to the point where your doors and windows aren’t opening easily, your floors are uneven, or you can visibly see that your roof line is wavy or uneven, you are more likely to have foundation issues.

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.

Some foundation repairs are permanent, like underpinning and exterior drainage systems like the French drain. These fixes address the underlying problems—insufficient support from the soil and hydrostatic pressure on your foundation walls, respectively—so they can last for many decades, making them “lifetime fixes.” There are other solutions to address these issues that will last for up to a decade, making them temporary. These include slabjacking to raise concrete slabs back into place and dampproofing to reduce the water in the soil that interacts with the concrete foundation.

Trenchless sewer replacements are actually a great solution for sewer lines located under concrete. A professional can still sleeve and burst old piping to make room for a new one without having to dig up your slab.

Yes. Water can penetrate through a concrete foundation wall. This can happen whether or not you have cracks, as concrete is a porous material. You’ll want to take steps to waterproof your basement or crawl space.
