"⭐⭐⭐⭐⭐ We had Adirondack Basement Systems come to our home to lift our foundation, and we could not have been happier with the experience. Mikey, the foreman, and Justin, the installer, were absolutely fabulous from start to finish. Both were professional, friendly, knowledgeable, and incredibly efficient. They took the time to make sure the job was done right, kept us informed throughout the process, and made what could have been a stressful home repair feel completely manageable. It is so refreshing to have a crew come into your home who clearly takes pride in their work and also genuinely cares about the customer experience. Mikey and Justin represented Adirondack Basement Systems exceptionally well. We would absolutely recommend both of them, as well as Adirondack Basement Systems, to anyone needing foundation or basement work. Five stars all around. Thank you, Mikey and Justin, for such a positive experience!"

"When I contacted All Dry I was gun shy. This would have been my 4th contractor I would have to deal with. All theee prior told me something completely different and tried to take advantage of my limited knowledge. From the get go, All Dry Basement made me feel extremely comfortable. Todd and his team answered my questions thoroughly and were always available for my questions . The work that was done was amazing, he was punctual everyday and worked some nights until 8pm until the work was completed. It is like a different world in the crawlspace, the smell is gone, all of the debris were cleaned out and. Brought to the dump, a vapor seal was installed, a dehumidifier for the moisture, one entryway to the crawlspace was closed up and the main entrance was re worked for easier access. Blocks from the foundation were grouted because the blocks were dead, , floor joists were spay flames and the House is now Warmer. I couldn’t be more please wth the quality of work All Dry Basement did at my home. They were professional and amazing and I would 100% recommend them. My stress level has decreased a million percent because after two years I found a company that was honest from the get go and their work shows it!!!! HIRE THEM FOR YOR CRAWLSPCE AND BASEMENT NEEDS. Do not look any further."

"I recently had my kitchen remodeled, and I couldn?t be happier with the results! From start to finish, the team was incredibly professional, communicated clearly every step of the way, and completed the project right on schedule. The quality of the work exceeded my expectations, and the price was very fair for the level of service and craftsmanship provided. It was such a smooth and stress-free experience, and I truly appreciated how respectful and reliable the crew was. I would absolutely hire them again for future home projects."

"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."

"Nick was honest, knowledgeable, and professional. My sump pump was making a loud noise, and instead of recommending an expensive replacement, he cleaned the pump, removed years of mud and debris, re-centered it, and got it working again. He also explained how my primary pump and water-powered backup system work and only recommended what was truly needed. I really appreciated his integrity and would definitely recommend him."

"I needed stucco repair work on an old chimney (and other spots). Grady was meticulous and thoughtful on what approaches and materials would work. Throughout the project they allocated sufficient time for each treatment to cure and inspected the work before proceeding to the next step. Grady started the project with no money down and only required ongoing payments for materials until the project was well underway. The final payment was due only after they did a final inspection. Total project cost was also below other bids."

House Leveling questions, answered by experts

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

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.

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 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.

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.
