"I just bought a new house, where one room had a noticeable slope in it. I believe it was because this room used to be the garage before a remodel. I had RamJack come out to check it out to make sure there was not an issue with the foundation. They showed up and looked at the room, checked out the outside and performed some tests with their instruments. He could have scared me and told me that I needed lots of work, because honestly I have no idea about foundations and I was willing to pay to fix the issue on my new house. However, he explained to me that he did not believe there was an issue and that the house was fine. He said when I replace the carpet, to have the flooring people level out the slope and that should take care of it. It is great to work with those who do their best to give you accurate honest advice and not try and use your lack of knowledge against you. All of this was done for no cost, and that is what puts the cherry on top of this story. I know if I ever do have any issue, RamJack is the first place I will call, since if they tell me there is any issue I can trust that there really is one."

"From consultation to completion the team at Groundworks handled our foundation repair with care and professionalism. Matthew came to the house and stayed to answer every question and explain every detail. He took the time to complete a bid while onsite and walk us through the process. (BTW their permitting department and financing through GreenSky really helped!) When the work started the first team of Alex, Iuni and Luis, were exceptional (they pier leveled the footing). We got texts the moment they arrived at the property and they got right to work, completing their part right on time. They worked as quietly as possible and kept us informed of the progress. The second team for foam leveling our slab and led by Daniel, got it all done in part of a day. They were also courteous and even helped move furniture. When the work of both teams was finished Alex, the foreman, walked us through an inspection and answered all our questions. Finally, Matthew circled back at the end and made sure"

"They leveled our patio and we were extremely impressed with the professionalism of the crew. Unfortunately, the patio sank a couple of inches within a month and they returned again, at no cost, and re-leveled. We are hoping that it will stay but, whatever happens, it is not the fault of their expertise but rather the ground continuing to shift. That is our personal assessment."

"I couldn't imagine a more dedicated construction team than these two. Have never seen somebody put so much time and effort into making sure everything is done just right through all phases of the project. Extremely communicative. Very professional. And just all around, great humans to work with. They put down protective floor coverings anywhere that they were walking or working in my house. They put up plastic wall barricades to keep the dust out of the other parts of the home that they weren't working on. They kept us informed about everything they were doing each day and showed us their progress at the end of the day."

"The contracted the work off to a third party. Jon took longer than expected. The windows was installed pretty good from the looks. Communication could have been better with knowing the job will take longer and what types of trims I wanted for the windows. As the contractor that was hired for this job by this company. Did a good job with putting up decent trim. As for the new windows they look great. I purchased the myself and hired sentri homes to install them. I will need to have a my siding on my house redone to be closer to the new windows so the gaps are not so obvious. That was not expected at first. But from old storm windows and not knowing how they were put in originally. There was some unknown things that was learned from the job being completed. I will have the siding of the house slightly done to match really good for what I wanted later on. My only concern is better communication with sentri homes. Overall they were great when I did talk to them."

House Leveling questions, answered by experts

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.

Concrete leveling can last anywhere from five to 10 years or more, and in some cases, it can be a permanent solution. The longevity depends on the method used and whether the underlying cause of the sinking is addressed. For example, mudjacking typically lasts five to 10 years, while polyjacking can last for 20 years or more. It's best to consult a professional for an accurate timeline based on your specific situation and any factors that could cause the issue to recur.

Polyjacking and mudjacking can both be effective solutions for sinking concrete, but they have key differences. Polyjacking, which uses expanding polyurethane foam, is often considered a better option because the foam is significantly lighter than the cementitious material used for mudjacking. This reduced weight puts less pressure on the underlying soil and lowers the risk of future sinking. Polyjacking is suitable for any sinking concrete slab, while mudjacking is typically only recommended for non-structural concrete, such as sidewalks, patios, pool decks, and driveways. The primary drawback of polyjacking is its cost, which can be up to four times higher than mudjacking—as much as $25 per square foot compared to a maximum of about $6 per square foot for mudjacking.

Concrete leveling is absolutely worth it if you have sunken concrete slabs and want to restore them to level, especially if the slab is part of your home foundation. Concrete leveling is less than half the price of replacing concrete sidewalks, patios, walkways, and pool decks, and it’s about a quarter of the cost of replacing a foundation. If you also treat the underlying problem, it can be a worthwhile and permanent solution.

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