"I recently had the pleasure of working with Oswaldo and his team for a foundation repair project, and I couldn't be more impressed with the service they provided. From the moment they arrived at the job site, Oswaldo displayed exceptional professionalism and expertise. He quickly assessed the areas that needed attention and promptly updated the repair plan to ensure it met the specific requirements of the situation. Despite facing challenging weather conditions—snow and ice melt, followed by heavy rain, and an unexpected flow of water under the house—Oswaldo and his team showcased remarkable perseverance. Their dedication to completing the job, no matter the obstacles, was commendable. Additionally, I appreciated Oswaldo's commitment to communication. He kept me thoroughly updated on the project's progress and any necessary changes, which provided me peace of mind throughout the process. Overall, I highly recommend Oswaldo and his team for any foundation repair needs. Their experti"

"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."

"The entire process went extremely well. The estimate was very clear about the scope of work, the crew was professional, on time and carefully about reducing disruption/mess and our basement is dry, as promised. They even went above and beyond and fixed a downspout outside so water would flow away from the house. Once the job was finished, the company rep came out to walk through with us and answer any questions. I have no doubt that if a problem did arise, they'd fix it."

"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

Cracked tiles can mean foundation problems. Fortunately, most of the time, cracked tiles happen as a result of accidental damage. It is important to determine the cause of cracking to rule out underlying foundation issues. If your tiles were not damaged due to dropped items, heavy loads, poor installation, or inferior tile quality, and the cracks are spreading throughout your flooring and not limited to just one area, you may be dealing with foundation problems. These can include drainage problems and even foundation failure, so it is vital to call a licensed contractor to assess the issue and ensure your foundation is safe.

Whether or not repairing your foundation is worth it before selling depends on the extent of the damage, the cost of the foundation repair, and your timeline for relocating. If the damage is major or structural in nature, chances are you’ll sell at a higher price if you take care of the problem beforehand. You should consider the cost of the repair first, though, as laying out thousands might not be possible with your budget. Additionally, if you’re in a rush to relocate, you might want to repair before selling so as not to limit your buyer pool.

A sinking foundation can be lifted, most often by installing piers to re-level and support the weight of the house. Depending on the cause and extent of the sinking, other methods to lift a foundation include underpinning and mudjacking. Consult a foundation repair pro to determine the best way to lift your sinking foundation. 

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.

Mudjacking is usually reserved for light-duty slabs, like patios, driveways, and sidewalks. However, it can be an effective way to lift garage slabs and concrete around the perimeter of the home, which could harm your foundation if it’s not done properly. The risk of damage is why having a professional mudjacking company carry out the work is important. This type of slab or foundation repair is relatively inexpensive, especially if you consider that a DIY job requires that you pay to rent the necessary equipment.
