"We hired them to build a retaining wall to level out our sloped backyard and install a new patio. They recommended natural bluestone bordered by classic bricks, and wow?what a difference! The stonework is flawless, perfectly level, and handles heavy rain with zero drainage issues. It looks like a high-end resort back here now. Worth every penny."

"Amazing! My sidewalks were a trip hazard. I could not enjoy my front porch because I thought someone would trip every time they walked by. First Quality came by and in ONE HOUR my sidewalks were level. I only wish I did this sooner! I can now enjoy my front porch again! No mess, really professional work men, great work! Thank you! Thank you!"

"HIGHLY RECOMMENDED!!! We just had a French drain installed along with a new sump pump and pit in our basement and had the floors epoxyed afterwards. The project manager, Kenny, was absolutely amazing. From the very beginning he explained everything that their team would be doing, gave me updates throughout the day. If I had a question or concern Kenny was patient with me and continued to make sure any questions/concerns were addressed, even telling me to call him if I thought of any other questions. Their crew was very respectful of the property by making sure to lay out tarps to protect the floors, and made all attempts to manage the noise since we were home. Whatever was left in the basement they made sure to cover and protect. And if something needed to be moved they moved it and moved it back. When it came time to lay down the epoxy there was a scheduling hiccup. Kenny though went out of his way to make it right by coming right after another job and staying late to make sure we're stayed on schedule since I was having out of town guests coming that weekend and needed access to the basement. Working with Select Basement, but especially Kenny, made this one of the best experiences and I highly recommend them. 10 out of 10!"

"My wife and I were having trouble in our basement, as we were getting a mysterious puddle down there every so often, and we couldn't figure out where it was coming from. We'd had vents replaced, sump pumps replaced, and then had two other basement companies come in to look at the issue. Now, we have french drains down there already, but they were installed before we bought the property. Both of the first two basement companies told us our drainage system was either all wrong or installed improperly, and that we'd have to install a whole new system along one wall for $4k (said the first company) or along all four walls for $14k (said the second company). That didn't seem right to me, particularly as we had a drainage system, but both companies seemed to care more about their sales pitch than addressing the problem.
At that point, I signed up for Angie's List (moral of the story, thank you AL) and called American A-1 with my hunch. Jeff came over the next day and was first and foremost a super friendly, extremely knowledgable guy.First, he took a look at our current drainage system and said something the other two hadn't — that, while he would have done one or two things differently, our french drains looked to be installed perfectly fine. So he started poking around other places as I explained what the other two companies had said. He wasn't only shocked at the price, but mortified that somebody would tell us to rip up our basement like that. As a former building inspector, he seemed to really great knowledge set in general (he even gave me some free tips as he was looking around), and eventually came to the conclusion that he thought it was a plumbing issue, most likely something to do with the boilers. Jeff said he wished he could do more, but he wasn't a trained plumber, but said that would be his next phone call. He wished me all the best and left his card.
Fast forward a few weeks, and it turns out Jeff was exactly right: a plumber came out and confirmed it was one of the boiler's pressure release systems going off intermittently, and projecting in such a way that it ended up as a puddle far away from it. No basement drain installation necessary.
Seriously, I cannot say enough nice things about these guys. Not only did they save us money, but they saved us from having our basement ripped up and not even having the issue resolved. Jeff didn't make me sit down and listen to a half-hour to an hour sales pitch about this, that, and the other thing — he came and did what I wanted the first two companies to do: try and figure out the problem and not assume they knew what it was.
While I can't speak to their actual work, I can say that I would recommend American A-1 in a heartbeat. I think it's easy to be cynical about service providers these days — and as my first two basement companies goes to show, you should still be — which is why when you find one of the truly good ones, it's such a revelation. American A-1 truly is one of the good ones. Don't hesitate to call them."

"I rarely write reviews but how can you not when they did an outstanding job for the most reasonable price I could find. My stairs (concrete/limestone/brick) completely cracked with the most recent snowstorm and I was desperate to get it fixed. I called Wilmar and he came right away and gave me a reasonable price. I have a good gift in judging character and integrity. Wilmar was completely transparent with the price and how long it would take to do the job. He gave me the date and time and he was actually right on time and got the job done perfectly in time for me to move on to my errands for the day. My stairs came out PERFECT. I love efficiency and Wilmar also let me know of other things I should consider fixing in the future. I’ve got a lot of work to do on my house and I found my go to guy. Look no further- these guys are great."

House Leveling questions, answered by experts

Polyjacking can be a permanent solution to sunken concrete if you also address the underlying issue—like poor drainage—at the same time. The polyurethane material itself can last as long as or even outlast the concrete you’re lifting it with. Your sunken concrete issue will likely return if you don’t couple polyjacking with proper drainage to prevent future soil movement and sinking.

A slurry of cement, sand, and water is injected beneath the concrete to lift and stabilize it.

Yes, expanding foam (also known as polyurethane foam) can lift concrete. This approach, called polyjacking, involves injecting the foam rather than concrete slurry to fill voids and raise the concrete slab back into place. It’s often faster and requires smaller drill holes than traditional mudjacking, though it may come at a higher cost. Some contractors also prefer polyjacking over mudjacking for more damaged and delicate slabs.

Common issues with concrete that may require professional repair or resurfacing include cracks, spalling, uneven surfaces, and weather damage.

There is no real alternative to underpinning, although mudjacking and polyjacking are other repair methods that can add support from underneath your foundation. Rather than placing supportive piers under your structure, these involve pumping a material under your slab to lift a sunken section back into its original position. Polyjacking, in particular, is sometimes a suitable solution for stabilization issues under slab foundations, but underpinning is often accepted as the best and most permanent solution.
