"Dave Nessel and his stellar company, Unique Construction NY Inc. are the BEST. Allow me tell you why- On May 15th 2022 at 5:45 p.m., my house was hit by, what electrical engineers later estimated, was at least 80,000 volts of lightning. That huge, direct surge of energy destroyed all the systems and contents that made my house more than four walls and a roof. In addition to the bolt of lightning destroying all the systems in the house, it caused a violent, destructive fire. Thankfully I was home at the time of the incident, or the house would have quickly burned down all the way down and my pets would have suffered a terrible fate. Still, after all was said and done what had been my home for seventeen years was reduced to nothing more than an outer shell. I was immediately forced into the position to find, hire, and organize tradesmen from all specialties, negotiate the endless complexities of homeowners insurance, all while trying to find a place to live and continuing my self-employed full-time work schedule. It quickly became clear I needed the services of a general contractor. I interviewed a couple, but as soon as I met Dave I knew he was the man for the job. Dave was always on time or early. He went through the house with a fine tooth comb for hours, noticing things and problems from the destruction I hadn't noticed. His expertise of every level of construction and understanding of all aspects of housing systems (electrical, plumbing, etc) was unmatched by anyone else I had interviewed. Additionally he had an understanding of the homeowner insurance protocols and was able to interject as a supporting role (only when needed, Dave never undermined me -I'm a single female homeowner-) with professional, easy to read, paperwork, accurately demonstrating all costs. I'm confident his detailed documentation made the long slog of negotiations with my insurance representatives a little easier. Under his expert guidance, his company gutted and rebuilt my old house to beautifully modern standards while maintaining its historical charm. The rebuild came in precisely on budget and two weeks early. Dave's company Unique Construction handled my complex situation with upstanding processional skill, old fashioned kindness, and outstanding forthrightness. Dave and his crew treated me with respect, rebuilt my home, and provided a little hand holding & TLC when it seemed I needed it and I'm eternally grateful. Anyone reading this should hire Unique Construction!"

"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!"

"the job was very professionally done.  There is not much to say except that I was very pleased with there work and happy that I don't have to worry every time it rains.  other contractors would have just dug a hole and put in a pump, but they covered back up the hole except for exhaust pipe which leads out of the house to underground.  It takes water a significant distance from my house.  Thanks guys.

"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

Polyjacking can be a permanent solution to sunken concrete if you also address the underlying issue—like poor drainage—at the same time. The polyurethane material itself can last as long as or even outlast the concrete you’re lifting it with. Your sunken concrete issue will likely return if you don’t couple polyjacking with proper drainage to prevent future soil movement and sinking.

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.

On average, a mudjacking repair lasts between five and 10 years, though it can sometimes last for well beyond a decade under ideal conditions. Its longevity depends heavily on several factors, including the condition of the underlying soil, environmental conditions like freeze/thaw cycles and erosion, and whether the root cause of the sinking, such as drainage issues, is resolved. Because it doesn't always fix the underlying problem of loose soil, mudjacking is often considered a temporary solution. Proper maintenance and evaluation can help extend its lifespan.

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.

Mudjacking is suitable for sidewalks, driveways, patios, and nearly all exterior flat structures. However, it may not suit severely damaged or heavily cracked areas.
