"I called JES Foundation Company for a free inspection of my crawl space. I was concerned about a crack in my foundation wall. JES inspector Richard Sheman Showed up to inspect my foundation. He sent a text with the time of his arrival. He was pleasant and on time. He went into my crawlspace and inspected the crack in the wall and stated I had nothing to worry about. He was very knowledgeable about the foundation and itâ  s structure. He explain to me how I could fix the superficial settling crack and save a bunch of money. I appreciate the honesty of the business and I would recommend it to anyone who had the same concerns, and for any of their other services. Ron P Home owner."

"Service was great from sales, to installation, to post installation support. Very responsive, very professional. It's hard to find in this 'space'--there are a lot of shady people in basement water damage/repair, and this place exceeded expectations. We've had our repair in place for 4+ years, with only 1 small issue on a wall seam crack, and that was fixed within 24 hours of reporting the issue. Stand up place! Thank you for such great service and support."

"AA action waterproofing was amazing!! Our basement completely flooded and our first estimate for a sump pump repair, a second sump pump installation, and a drainage system the entire perimeter of the basement (109 feet) was ridiculously high and simply not affordable. A friend recommended AA Action and I am so glad we called them. They came out for an estimate within 24 hours and their estimate was much more reasonable. The crew that came out to do the work were trustworthy, friendly and very knowledgeable. They even hauled our carpet away! The fact that they have a lifetime guarantee made choosing them even easier, it shows they stand by their work. I could not be happier with this company!"

"My experience with this company was great. I was able to tell them my issues and they gave me several options. Ultimately we went for the full French Drain system. Everything was done on time and the estimates were very fair. Warranty on the work is great. I would call them again if needed."

"This company impressed us from beginning to end! The estimate and finished price were far lower than other quotes, while the quality, speed & cleanliness of work was far superior to what others offered. They hung plastic sheeting & barriers surrounding the whole work area & used a ventilation system so there was never dust anywhere. ( Concrete dust is dangerous, not just messy!) The entire team ( 5 people 1st day, 3 on 2nd day) always removed shoes & treated our house & us with respect. They walked us through the steps of the job, showed us the work & the damage/ wet areas & the undamaged areas at several points as they were doing it (without being asked). Tested sump pump in our presence... without us asking. In addition to other source of water, they found a crack in the foundation & worked to examine the extent of damage.. which went all the way from outside in. They showed us the full damage, offered to fix this more completely, explained options to do or not do that work, but never pressured us. They provided life-of-structure warranty. They even told us they caused a tiny area of damage to woodwork on a window sill ( I would never have been upset about) when they were done THEY pointed it out and THEY spackled & fixed it ( like 5 min work.) The whole job took 1 and a half days. Like anyone, I was heartbroken to have started finding water in my finished basement & terrified of the cost & the process of fixing it. This company made this as affordable, convenient & low-stress as I can possibly imagine."

"I had a bad water issue in my basement and instead of digging up the concrete floor and installing french drains, Humberto addressed the issue of water getting in in the first place. He sealed and refinished our driveway and waterproofed the area where driveway met the foundation of the house. Also installed sump pump in landing of basement stairs and installed drains in the window wells. He was very responsive and wonderful to work with. I highly recommend!"

"Tru Integrity, LLC lives up to their name. My basement flooded twice this year due to sump pump failures so my husband and I knew it was time to make some major changes. We interviewed 3 companies, even big name companies and Wendell (the owner) was the only one that explained things and did a thorough assessment of our property to figure out how to fix our sloping and minor foundation issues and within our budget. His team arrived on site on time and worked a full day until the job was completed. Our basement was left cleaner than they found it. We added another sump pump due to the size of our basement and that drain well looks better than our original. This will allow any water that maybe overworking the main pump to be redirected and pumped out on the opposite side of the house. I'm happy with the look and everything is so quiet now."

"I had a great experience with Guardian. The team was on time, hard working, polite, and left the house spotless. They repaired the drywall they needed to cut into and showed me all of the work as it progressed. The work also came with a lifetime guarantee. I would definitely recommend this company.

Foundation Repair FAQs, answered by experts

Foundation repair costs $250 for a minor crack that doesn’t affect the structure’s integrity, although it can cost as much as $800 if it’s a major crack. Call a pro to get it fixed as soon as possible if your crack is bigger than 1/8 inch wide. Additionally, if you need to seal the foundation to fix leaks, it can cost approximately $2,000 to $7,000.

There are many actions that specialists can take to repair a bad foundation. However, just like a car, a specialist will determine whether the cost of repairs is worth it in the long run. In many cases, repairs to the surrounding property—such as regrading your lawn or addressing lawn drainage issues—will also be necessary.

Whether you need a permit for foundation repair depends on your location and the scope of the work. Major repairs like foundation stabilization typically require a building permit, while smaller projects such as sealing non-structural cracks or applying waterproofing solutions often do not. It's crucial that your contractor follows all local building codes, as an inspector will review the work to ensure it's up to standard. Failing to obtain the necessary permits can create issues when selling your home and may lead to further damage if the work is not done correctly. Your foundation repair specialist will usually know if a permit is needed and can handle the process for you. You can also contact your local building department or municipal office to confirm the requirements and verify that your contractor has filed the appropriate paperwork.

Cracks, shifting, or uneven floors indicate potential foundation issues.

Yes, you can replace a cinder block foundation. If a block foundation is too severely damaged to repair cracks and other issues, replacing the entire foundation is a viable option. The job will require a professional and can take between one to seven days on average to complete, depending on how complex the problem is.
