"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!"

"I was having some issues with water coming into the basement through the foundation and walls during rainy weather. Not flooding, or even shop vac-able volumes, just enough to be annoying and require mopping. Dominic and his crew were here today to install an under-floor drainage system and a new sump pump. I was dreading the demo (I have a concrete floor) and the mess involved, but these guys came prepared for everything! They used dust abatement measures to protect all my basement-stored items, and they removed and hauled all the debris away when finished with the excavation. What really impressed me was the concrete restoration upon completion. I've previously had a sewer line replaced through the basement floor, and the contractor really "botched" the floor repair. I can't describe how different this experience was! The concrete installed today is immaculate! Dominic takes pride in his work and with good reason! The new concrete is perfect! I am thrilled!"

"Water started leaking into my finished basement this past winter. Dan, from Archer Contractors, came out a few times, free of charge, to troubleshoot. He patiently and methodically examined all the potential sources of water entry while keeping suggested repairs to a minimum. He discovered that the cause was a back yard drainage problem together with a failing internal foundation drainage system and drew up a price quote with detailed diagrams for a plan to remedy the situation. The crew started immediately, keeping within the scope of work and cost outlined in the price quote. They installed a back yard drainage system to control storm water and replaced the blocked portion of the foundation drainage system. They were very professional and quickly but carefully completed the work, leaving the site spotless. Since then the basement has remained dry during numerous heavy rain falls, even during the rapid snow melt with rain that occurred this past January. I would definitely recommend Archer Contractors for any yard drainage or basement waterproofing issues. Not only was the work done properly, but Dan was careful to suggest only necessary repairs to keep the cost to a minimum."

"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."

"All Aspects Waterproofing installed a French Drain and new sump pump in my basement. The project also required adding a curb to the foundation. From the estimate to project close out, all of the employees were great to deal with - very responsive to emails and calls with questions and pro-actively called me to keep me up to date throughout the process of getting the permits and inspections, coordinating with my plumber who took out and installed new hot water heater, and coordinating with my own schedule. All of the workers who came and did the hard work were great - they worked very clean and went above and beyond helping remove items I needed to have out of the way for their work and left my basement and yard (where they needed to do some of the prep like making concrete) spotless. They were great - responsible, knowledgeable, honest, friendly, reassuring - and I would totally use them again. Also, great value."

"We had a crack in our concrete wall from top to bottom, with water leaking inside about mid-way down. We got estimates for this work but the presentation from AquaGuard convinced us they were the ones to go with. So when it came time to do the work I was totally surprised that they could come in, remove our landscaping, dig down about 8' deep and 6' wide to the foundation, repair the wall, put in a silo and sump pump, and restore it all such that you would never know anything had been done. And they did it all in one day! My wife was there and she said she was amazed at how they covered the grass with a tarp and all of the dirt being dug out was placed there so as not to disturb the yard. When I got home I expected to see a big hole and possibly a mess of my yard. As I pulled up to my house I assumed they had not come by so I walked around to the side to see what was going on and was really surprised the work had been done and everything returned to normal. Naturally it has not really rained yet for me to see if the repair has worked but when it does I'm sure, based on how professional the outside work was done and from what my wife indicated, the repair will pass with flying colors. I highly recommend AquaGuard for their professionalism and quality of work."

Foundation Repair questions, answered by experts

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.

If foundation problems are not fixed, they will likely worsen over time, leading to more complex and expensive repairs. Neglecting a damaged foundation can cause a range of issues, including:

  • Structural Damage: Minor problems like small cracks can escalate into major structural issues. This can damage the house above the foundation and, in severe cases, lead to foundation walls caving in or a total collapse.

  • Water Damage and Pests: Moisture and water intrusion can cause flooding, mold growth, and pest infestations.

  • Health and Safety Risks: Mold can lead to poor indoor air quality and other health risks, while structural instability poses a significant safety hazard.

  • Reduced Home Efficiency: A compromised foundation can negatively impact your home's energy efficiency.

To avoid these escalating problems and costs, it's best to hire a foundation repair company to address any issues as soon as you become aware of them. The earlier problems are discovered and fixed, the lower the repair cost will likely be.

The most cost-effective foundation repair is using masonry patches and sealants to seal foundation cracks and offer some support to prevent further damage. These methods are used to fix minor foundation cracks quickly. However, they’re not suitable as a long-term solution, and they only offer minimal stability. On average, masonry patches and sealants cost $500, but a sealant like an epoxy crack injection can total over $2,000. If you’re handy and only looking for a temporary solution until you contact a local foundation repair contractor for a more permanent one, you can save hundreds by DIYing this repair.

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.

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.
