"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!

"Olshan is a great company. Alejandro and his crew did an excellent job in repairing our foundation and getting the chimney back against the side of the house like it used to be before the foundation shifted. Expensive, yes, but quality work usually is AND worth it!! My hat is off to Alejandro and his crew. They were very careful to put down paper so as not to track mud into our home. They were very careful so as not to disturb the cable wires running along the foundation. These guys were just great, Thank you."

"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

If your concrete steps have crumbled or chipped, you can fix them by removing any chips or flakes, cleaning and wetting the affected area, applying a concrete bonding agent, and finally applying new concrete, usually in the form of Portland cement. For widespread damage, you can consider concrete resurfacing instead. For fixing concrete spalling that has led to deep damage, you might need to remove damaged material, add structural supports, and pour new concrete into a mold.

You can strengthen a weak foundation using a few different foundation repair methods, including underpinning, slab jacking, foam jacking, installing carbon fiber support strips, or using a sealant or epoxy crack injection. It’s worth noting that the best way to strengthen your foundation permanently is to fix the underlying issue first and then use a permanent solution to reinforce it. If you’re unsure who to call for foundation repairs, a foundation repair contractor or structural engineer can help find the best solution for your home.

Foundation problems are costly to repair, but if you already own the home, you can either handle the issues or allow the property to (literally) sink into disrepair. The opposite is true when buying a home. Walk away if the seller refuses to lower the asking price once foundation issues are exposed or if they refuse to handle the problems before the completion of the sale.

Most single-story homes don't have foundations strong enough to support a second story, but they can be reinforced for an addition. A structural engineer can assess your foundation and what needs to be done to get it ready. They'll look at any cracks or unevenness in your current foundation and consider any special framing or beams your home needs, especially if it’s in a high-wind or hurricane area.

“To support a second story, many structural engineers will require that you install additional concrete piers in the crawlspace,” says Tschudi. “This involves hand excavating, pouring a large concrete footing—usually with specially coated rebar—and then building concrete piers right up to the girders.”

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.
