"When you hire someone to do a major project like reworking your basement so it doesn't flood, you hope that they 1. solve the problem and 2. stand by their work. Our situation was challenging in that it took a few tries and commitment to solve the problem. Acculevel stood by their work 120% which is not an exaggeration. When their initial solution unfortunately did not work as well as planned, the level of care and things they did to remedy the situation were well above and beyond what I know others would have done. They made it right and then some. It is my opinion that the challenges we faced would have occurred with ANY provider, but Acculevel kept their promise to fix our problem vs find a way to exit. A rare and refreshing character trait for the individuals and company. Highly recommend them. Thanks Nolan!"

"He was a nice man but I don't think he was much of an expert in waterproofing. He was prompt. I think he was a businessman who purchased the business and didn't know what to do. I just needed someone who knew what he was doing. The deal was not a good deal because he was just coming out to do basic inspection, which other companies can do for free. The whole thing was kind of bogus. When he came out, he first mentioned something about drain tiling. I asked him where he was going to put the drain tiles and  he wouldn't even take another look. He came back again and said he didn't realize it was another level. He said he was going to recommend a french drain. Honestly, it was like a doctor who thought the patient wanted something to walk out of the door with and didn't know what to give him so he just wrote a prescription. It just didn't apply. I'm sure he knows what to do in standard, easy to read situations. I wouldn't recommend him. He told me he had another business which he tried to interest me in."

"I was very impressed with Sentri Homes - their customer service was excellent. They sent a subcontractor to install some vinyl laminate in my bathroom and he ended up getting glue all over the carpet in our bedroom. The sub ended up ghosting both me and Sentri, leaving me stuck with a ruined carpet. Sentri stuck with me for over a month to get the carpet replaced with the identical original and to get the vinyl job 100% completed. The carpet was a Home Depot exclusive and Sentri handled everything with them. I will be using Sentri for a much bigger renovation I have coming up soon, because I know that they will make sure everything gets done right no matter what problems come up. The vinyl looks great too."

House Leveling questions, answered by experts

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.

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.

It’s best not to perform mudjacking in the winter unless the ground temperature remains above freezing. Freezing temperatures can cause the slurry to harden too quickly, compromising its strength and longevity. Concrete is also more susceptible to cracking and splitting in cold temperatures, so there’s a higher risk of damaging the slab during the drilling and lifting process in winter.

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

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