"Uneven Floor Solutions is On the Level After I bought a 45-year-old ranch house, I noticed that some of the floors were not so flat. Some places stood out as high ridges and other places sloped down into valleys. The highs and lows were not so noticeable when the floors were covered in carpet, but once the carpet came off, they stood out more clearly. I decided that something must be done. I set up an appointment with Mr. Masle Gamez of Uneven Floor Solutions. He came to the house, evaluated the situation, and recommended a plan to fix my uneven floors. Talking with Mr. Gamez inspired my confidence that he knew what he was talking about and could deliver on his promises. I was pleasantly surprised when an early date was set for the crew to begin work. They showed up at the appointed time and promptly set to work in a businesslike manner. They had the proper protective safety gear and the specialized tools for this job. Partway through the job, Mr. Gamez led me on a guided tour through the crawl space, showed me the problems to be fixed, and pointed out the progress so far. When the job was almost complete, a specialized measuring device was used to help visualize the unevenness of the floors and control how much correction was needed to make them flat. At the end of the job, Mr. Gamez showed me pictures of the work done in the crawl space, which saved me from returning there to check the work. I am very satisfied with the work that was done. The recommended solutions addressed the real problems, and I feel I received great value for the money spent. I would highly recommend Mr. Gamez and his crew to anybody who is faced with uneven floors."

"Greg, Marcus, Bill, and Clark did the work on my house. they were a pleasure to work with, on time each morning, cleaned up the job site, and did a great job on leveling my floors. There was a significant sag, but it is not even noticeable anymore. I would be happy to use them again.....would hope for the same crew, really good."

"Elliot called me in reply to my online inquiry. He (patiently and professionally) answered my many coverage and price questions, then gave me time to 'digest' it all and called me back (as promised) at 4PM...to answer more questions. Elliot also worked with me to secure the maximum amount of discount savings. Time will tell if the warranty coverage/work is what it's cracked up to be, but Elliot Chahino is an excellent salesperson. Reach out to him directly if you want the same level of service attention.

"Life Savers!! We live in an older house with a very small bathroom. We had a home inspection recently and were altered to some major subfloor, sill and joist damage. We knew it was in rough shape but the inspector used terms like “100% moisture and “previous repairs poorly completed”. I called a few other contractors and remodel companies that started to throw around some huge numbers and timelines to make the repairs. The consensus from them was the tub would have to be removed before they could do any subfloor repairs. In a house with one shower that wasn’t really an option for us. I saw the reviews for the Crawlspace Medic and decided to give them a call. It was the best decision I could have made. Sharon, Paul and Stanley were great; they made the process very easy and efficient from the initial phone call to the installation. Paul came out to do the initial visit (11/14) and assured me he had seen much worse and his company had developed methods to do all the necessary repairs from underneath the house leaving the current bathroom intact. The quote arrived the same day and was extremely reasonable. They got us on the schedule right away (11/20) and on the day of the repairs Nick and his crew arrived on time and were very professional. The job was scheduled for two days but they completed it in one and did a great job. We no longer have to worry about falling through the floor. They also provide a follow up inspection in 90 days and informed us of a couple other minor leaks that were noticed while completing the repairs. Crawlspace medic is a great company and I would 100% recommend them to anyone needing their services."

"They didn't end up doing the work. They were really high on what they wanted to do. Other people who looked at the porch said that it was not causing an issue with any water intrusion and that there doesn't seem to be any signs on the posts that this could have been recent, it could have been long ago. So no work was done. It was a front porch that had just the level concrete on one side was dipping just a little bit. I think they were going to pump it up from underneath or something like that to level it out. I would say that their response time and their professionalism of getting the quote to us on a timely manner was good. The quote was high and yet the work was not necessary according to other quotes. They should be honest to say when repairs are necessary and when they are not. The guy who showed up was nice and professional and was on time. There was a decent response time."

House Leveling FAQs, answered by experts

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

Mudjacking restores level surfaces, prevents further damage, and is more cost-effective than a full replacement.

The polyurethane used for polyjacking will expand and cure in 15 to 30 minutes. After that point, your slab will be safe to walk on and even drive on in the case of a sidewalk or concrete driveway. Double-check with your concrete lifting specialist to confirm a curing timeline, as products can differ.

Mudjacking is your best bet for leveling concrete on a tighter budget. It’s less expensive than foam or grout mixture. For smaller, surface-level issues, you could also use a self-leveling compound, which creates an even surface over existing concrete—it’s a budget-friendly option suitable for DIY enthusiasts.

The timeframe is generally a few hours, allowing for immediate use post-hydration, ensuring minimal disruption to surrounding activities.
