"Mauricio and Crisjan were the initial sales reps who came to examine the issue and they took the time to test drainage that might have potentially been creating the water issue. They offered a reasonable solution (sealing the visible cracks and holes in the concrete and I was contacted within a couple of days with an estimate and scheduling options. Sean was our tech and he did a fantastic job diagnosing the issue beyond just the cracks. He not only address all the holes and cracks in the concrete and mortar, he sealed up additional entry points above the foundation. He sourced additional materials to cover openings for cable lines. He went above and beyond and gave us measured information on how we should continue to monitor and treat this area as the house settles. He was thorough, informative, and provided excellent service in his work. I'm very glad that Sean was the technician sent to us and I would specifically request him for your projects."

"Howard Glancy came to inspect cracks in my home's concrete walls where the foundation was sinking. He, as a Certified Field Inspector, went over the whole house with me, explaining why the walls were cracking, and what should be done to alleviate the problem. Howard explained what JES Foundation would do, approximately how long it would take, and provided a quotation for the repairs. Besides raising the problem walls and ensuring they would be structural sound and guaranteed to stay that way for the remaining life of the house, he also advised me of how JES would repair minor cracks in the remaining building as well as having s sump pump installed to wick away any ground water from damaging any other parts of the structure. Mr. Glancy was very courteous; knowledgeable of his profession; and walked us through any questions we might have had concerning the processes. Due to the permit process taking so long, the work on the house won't start for a few months, and if Mr. Glancy is any indication of the professionalism of the rest of the JES Foundation personnel, I'm confident that the work will be done properly, in a timely manner and to my complete satisfaction."

"Jason was excellent and I will absolutely use AA Action Waterproofing for future projects. After having two other companies provide estimates for fixing our basement leak problem, I called AA Action for a third quote. The first two companies recommended extensive indoor and outdoor remedies with expensive price tags. I was a bit surprised because our leak is very minor. Enter Jason. Jason was friendly and clearly had extensive experience. He assessed the problem and pointed out that, while we could of course undertake the considerable actions the other companies recommended, it was more than likely that a simple fix of rerouting our gutter drain would fix our problem - a $20 fix that we could do on our own vs. the thousands of dollars in repairs recommended by the other companies. He told us that he could not honestly take our money knowing this small fix was likely all that was required. The remedy worked. It's rare to find Jason's honesty in the home contracting world; I will definitely call AA Action for any future issues."

"We got 5 estimates from companies regarding a leak in our office and adjoining storage unit. This was the only company that accurately pinpointed the problem , which was a leak coming from gaps surrounding our electrical conduit pipe. Other companies had quoted us 6400$ to dig up the front yard and redo everything from the outside. Others wanted to dig up the inside. I’m so glad Mike explained everything to me clearly- and it all came down to common sense. These guys found the exact spot where the leak was coming from, and knew how to fix it. He also suggested replacing our sump pump because it was the original, and mud was starting to back up. He suggested we do this as it would be tragic to fix one problem and have another occur (and subsequent flooding) that could have been prevented. There was a minor connectivity issue with the sump pump a couple weeks later but I called at 9 am, the man who took the call put it in as an emergency because of some water splashing out and the problem was fixed by 11 the same day. Great responsiveness and customer service. I feel confident in my decision to choose this company, and would recommend them to others."

"I highly recommend DES! I arranged a consultation after a home inspection report indicated that there was moisture in our basement walls. I was worried that costly mitigation efforts would be required. A friend who had previously used DES for a basement water problem highly recommend them, telling us that they were an honest company that only does what is necessary to solve a problem. Happily, Mark Fine from DES inspected both our basement and our exterior grounds and reported that there was no indication of cracks in the foundation or water intrusion, and that no work needed to be done. It is so refreshing to have a company that doesn't try to sell expensive services when they are not necessary!"

"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."

"Brothers Waterproofing did an excellent job sealing a crack in my basement wall. John was very professional and knowledgeable, and that is why I chose Brothers Waterproofing over other contractors. Given I had to rip open my basement walls to fix the crack, I wanted to be sure I employed someone with a sound approach and lasting product so that I didn't have to rip open my walls again. And, John and his team did an exceptional job. They sealed both sides of my basement wall and used quality products to secure the wall to prevent leaking in the future. I would recommend Brothers Waterproofing to anyone seeking out an honest and trustworthy contractor who will stand by his product and promise (which you honestly don't find nowadays). A+ service!"

"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."

"The work was excellent, however what was described and what was done differed. The maximum was described as the most extensive repairs. The repair entailed minimal digging and just the sealing of the main drain. It just 3.5 feet below the ground. One shrub was removed. They did not dig to the foyndation since they felt they found the issue. They did not reduce the price and that disturbed me since it was discussed."

Foundation Repair questions, answered by experts

Concrete can crack from general wear, improper installation, or in response to uneven support from the soil underneath. Small, thin cracks on the surface of aging concrete are usually a result of normal wear and tear, while cracks on new concrete more likely indicate a problem with installation. Larger cracks or uneven steps can signify a much more severe issue. A concrete contractor should be able to diagnose the cause and repair concrete cracks for you.

Foundation repairs cost about $5,000, on average. Typically, prices range from $2,200 to $7,800, depending on the type and extent of repairs needed. Cost factors include foundation type, home size, soil stability, accessibility, and the ultimate cause of the problem and what methods and materials are required to fix it.

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.

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.

Always hire a foundation repair contractor the moment you suspect your house doesn't have a good foundation. The longer you wait to address foundation issues, the more likely they can lead to bowing floors, cracks in walls and ceilings, sticking doors and windows, chimney and roof problems, and more. Foundation problems can also let moisture into your home, leading to water damage, mold, and mildew problems.
