"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."

"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!"

"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

Trenching and boring are two distinct methods for installing underground utilities. Trenching involves digging a channel using equipment like an excavator, trencher, backhoe, or shovel. While it is a simpler process, it causes significant disruption to the surface, landscaping, and surrounding ecosystems.

Boring, also known as directional boring, is a less invasive alternative that uses a drill to create a tunnel for utility lines without disturbing the surface. This method is more precise and is ideal for installations that need to go underneath buildings, roads, or bodies of water. Although boring is less disruptive, it is generally more expensive than trenching.

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.

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.

A sinking foundation can be lifted, most often by installing piers to re-level and support the weight of the house. Depending on the cause and extent of the sinking, other methods to lift a foundation include underpinning and mudjacking. Consult a foundation repair pro to determine the best way to lift your sinking foundation. 

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.
