"We were getting some water in our basement, which The Real Seal determined was coming from a crack in the foundation. They identified and repaired the crack quickly. Our technician worked neatly and efficiently, and all staff were pleasant and responsive throughout the process."

"If I had not had that put in, I would have been flooded a couple of weeks ago when we had water drainage here. I didn't compare the price to anything. I didn't take any other prices, so I don't know if that was a good price or not. It seems to be fine. It hasn't been in very long, but the sump pump works great. They were here right away. They did the work just like they said they would do it, in the time they said they would do it. Their work is guaranteed, so if something were to go wrong, I could call them and they would fix it."

"The worker who came over saw my situation and unoffically suggested a repair that would be cheap for me rather than have him and his crew come out and charge me a few thousand. I appreciated that he wanted what was best for me and not necessarily best for his company."

Foundation Repair questions, answered by experts

Detailed inspections and tests to determine the extent and cause.

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.

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.

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.

It is possible for a slab leak to cause a sinkhole, but it would have to be a particularly serious leak. A slab leak causes the land under your home to erode and if there is enough movement depressions will form in the ground, potentially causing a sinkhole.
