"Jeremy and Austin were hardworking, competent, and thorough in the completion of their jobs. They completed everything in 6 days instead of the allotted 10 days. They explained the jobs and even took pictures of completed work. They were engaging and professional and very polite. JJ Evans kept in touch with them and with me as the work progressed. I now have new floor joists and support beams, a vapor barrier, and a French drain to take away excess water. 5 Stars!!"

"The team worked diligently and professionally to Waterproof my basement after hurricane Helene caused water to come into my basement. They had to dig down into the foundation, fix the crack and apply waterproofing underneath my patio. While we haven’t had any big time rain since then, it’s been working against any kind of rain happening so far he also guarantees his work which gives peace of mind. They also encapsulated my crawlspace. It looks very professional and well done. It helps keep the humidity down in my crawlspace, and thus and the rest of my house. I would certainly recommend them to anybody who needs waterproofing solutions."

Foundation Repair FAQs, answered by experts

Regularly inspecting your foundation—at least the visible sections—for signs of foundation issues like moisture and pest infestation is a good way to identify slab leaks early, as is keeping an eye and ear out for water damage to indoor building materials, above-average water bills, sounds of running water when no fixtures or appliances are on, and indoor humidity that causes the temperatures to feel more extreme. If you do find any issues, contact a plumber right away to check it out for you.

Around 25% of homes have foundation problems - it’s a very common issue. Foundation problems can range from very minor to severe and urgent. Call a foundation inspector to determine the severity of any potential issues you identify with your foundation.

If your building department catches you or a contractor doing foundation work without proper permits, they will likely put the work on hold until you secure the necessary permits, which can cause delays of days or even weeks. You can also face violation charges for construction without a permit, which can cost hundreds, depending on where you live.

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.

Yes, it is normal for a block foundation to crack. Some block foundation cracks are more serious than others and indicative of a larger structural problem. On the other hand, minor cracks may not be of immediate concern but should be monitored. Regardless, foundational cracks are not an uncommon response to wear on a structure from time and weather.
