"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."

"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!"

"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."

"The project manager, Ms Tiffani Mercer, and her entire staff ensured all aspects of the job were on time and to specs. We were especially impressed with their hands on approach when dealing with County Inspection requirements. The workmanship was superb, professional and clean! Highly recommend and if we have the unfortunate need for other basement foundation services again, All Aspects will be the first company we will call!!"

"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."

"Mr. Romualdo and his team did a great job. The initial work was solid. After I asked about some spots that seemed to have a rough texture, they came back the next day and smoothed out the finish. They also applied a complementary finish to the adjacent area, which was not part of the agreement. Very good quality work, easy to work with and responsive."

Foundation Repair questions, answered by experts

You could DIY the work, but unless you have plumber’s knowledge for identifying and fixing a slab leak and specialized equipment in your tool shed, attempting to DIY your slab leak repair isn’t a good idea. It’s simply not something that the average homeowner can take on themselves, regardless of how many successful DIY projects they’ve got under their belt. You could, however, do something simple like foundation waterproofing yourself to save some money on the post-repair work.

Whether your homeowners insurance covers slab leak repairs depends on your specific policy and the cause of the leak. Many policies cover slab leaks resulting from a covered peril, such as a natural disaster, a falling tree, or pipes freezing and bursting within the slab. However, damage caused by invading tree roots, corrosion, or leaks from appliances may not be covered by a standard policy. It's a good idea to also check your home warranty plan for potential coverage if an appliance is the source. Contact your insurance provider for a full explanation of what your policy covers.

You can use a level or straight-edge to test for plumb foundation walls and a level slab, a level or a ball to check for sloping floors inside your home, and a hygrometer to look for moisture in your underhome area. Aside from these DIY tests, it’s important to get a foundation repair specialist or structural engineer to test the foundation to see if it’s supporting your structure properly. They can determine if the loads on the concrete are uneven or need reinforcement.

Yes, it’s worth it to repair a crawl space foundation, even if the issue seems relatively minor. Foundation problems often get worse and more expensive to fix if you leave them untreated. Additionally, your entire home, from the framing and flooring to the roof system, relies on the foundation for even and level support. Issues with your foundation will almost always manifest as problems in and above your living space, so it’s important to find a solution.

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.
