"Overall about the best contractor experience we've had from start to finish. The job took about 2.5 weeks. It began with the company's owner talking with us regarding contract and timing. The contract itself was a clear indication of throughness and detail. Every workday began with a chat of what was to be done and ended the day with a thorough clean up. On average there were three employees, all incredibly professional, very accommodating, great senses of humor and personable. For example, when they painted the entire interior, we asked if they could leave one bedroom and bathroom for last while they painted the rest of the house. On a few occasions, we asked for a paint color change. The contract didn't call for swapping out a few light fixtures but they did so without hesitation. Every request was fulfilled. They work was amazing. The house had some damaged Sheetrock and popping nail heads. Most of it had not been painted since the original paint job almost 30 years ago. The 20' ceilings presented real challenges but all was done so that the finished job makes the house look brand new. The carpentry, electrical work and door installation all are perfect. Most importantly, the professional workers clearly enjoy their work, enjoy working together and made this job for us, more like a social event with friends coming to visit daily. The owner of the company Dave Nessel is a serious (but with a sense of humor) knowledgeable businessman and a pleasure to work with. I would hire Unique again without hesitation for another job. They do quality, professional and spotlessly clean work."

"Tim and Jake replaced an old support beam and structural wall in our basement with new footings, posts, and steel beams through the length of the house. They handled the project from beginning to end with excellent communication and service. Before they could begin work, the engineer had to draw up plans and Diggs had to get permits approved. Tim worked in lockstep with the engineer and me - he stayed in touch so that I always knew where we were in the process. The work itself took them less than a week, and they left my house standing stronger than ever. If you have a structural issue in your home, these are 1000% the guys to call. Thank you, Tim and Jake!"

"Eric the consultant inspected the job site took the measurements he needed and gave us an explanation of how the work was going to be handled. He also offered a discount and scheduled our project for the following week. When the day came the crew arrived on time and went right to work. We will use them again in the future for our pool deck. Overall a great bunch of people and a greater service."

"I had a front porch slab that had been sinking for years. Clif came in and raised it & leveled it. I was shocked at just how many inches it had sunk... up to 8" in some places! I walked back-n-forth on it. It couldn't be more solid. Now that everything is level, the front facade of my house looks completely different, just so nice. So happy I found Clif!"

"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

The average cost for mudjacking is around $1,200, though prices can range from $300 to $3,400. On a per-square-foot basis, you can expect to pay between $3 and $8, with an average of about $5 per square foot. The final cost depends on several factors, including the square footage of the concrete, the type of slab, its accessibility, whether it is load-bearing, and the type of material used to lift it. Generally, lifting a driveway, small patio, or sidewalk is less expensive than lifting a slab foundation or garage floor.

A good slump height really depends on the project, but there is a use for nearly all slump levels. For example, low slumps are best in projects that require structure, such as curbs and roads. High slumps often require additional reinforcement, but they flow more freely into hard-to-reach spaces.

Mudjacking can be an expensive foundation repair process, but in many cases, it’s well worth the investment. This is especially true if you’re lifting a portion of sunken foundation slab back into place. In that case, mudjacking can help avoid major structural damage and even home collapse by restoring the integrity of your structure with minimally invasive procedures. Mudjacking a concrete patio, walkway, or sidewalk can be worthwhile because it removes tripping hazards and makes your outdoor area more aesthetically appealing.

Mudjacking typically takes 24 to 72 hours (one to three days) to dry and cure completely before you can resume normal use. The total drying time can vary depending on the size of the project. Because the slurry mixture contains cement, it needs to harden fully to prevent the concrete slab from shifting under added weight. You should avoid walking on the concrete or placing heavy items like furniture or vehicles on the surface until it has fully set. Your concrete contractor can provide a precise timeline. As a point of comparison, if you opt for polyjacking, the polyurethane foam can dry in minutes, but it's recommended to wait about an hour before use.

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.
