"⭐⭐⭐⭐⭐ 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!"

"It’s been 5 months since Todd and his crew encapsulated my crawl space but I wanted to wait to give a comprehensive review of their services and the outcome of their work. The short answer is: I’m thrilled! Here’s the story: Last summer I bought a small home which has a crawlspace. As soon as the weather turned humid I noticed a distinctly musty/earthy odor. When I had central air installed, all it did was exacerbate the situation by blowing the air from the crawlspace all over the house. To say I was distressed is an understatement. I wasn’t sure encapsulation was the answer but after calling around and doing some online research there didn’t seem to be any other obvious solutions. While I had built one new house (full basement) and gut renovated another (slab foundation) I found myself in new territory with an older home (60s) and a crawlspace. Doug came in and did a consultation. I had a lot of questions and deep dove the technical details. I’m sure it was trying for both Doug and Todd, but every question I had was answered promptly and thoroughly (something other companies failed to do). I decided to go for a full encapsulation solution with a commercial humidifier, drain, and some underlayment in particularly rough areas. Todd (and his assistant Kyle) did outstanding work and every unexpected issue they encountered was handled quickly and professionally. When they found rotting wood forms that were left from when the concrete supports were poured, they pulled them out. When they found some rough areas of construction debris around the perimeter, they cleaned that out. And when Todd found some minor seepage in the corner of the crawlspace that he traced it to the outside where a downpipe was punctured and draining too close to the house, he went and bought some new downpipe and repaired it--charging me just for the materials. To say that these guys went above and beyond is an understatement. Any homeowner knows that feeling of having made a horrible mistake and I wasn’t sure the crawlspace issue could be fixed. Not only did Todd and his crew do an amazing job but they put me at ease throughout the process. They were punctual, tidy, thorough and just generally great to work with. I couldn’t recommend them more highly! (Now if only I could find other contractors who are just as good…) P.S. The other reason I waited so long to write a review is that in my particular situation, there is little separation between the air of the crawl space and the rest of my small house. So after it was first encapsulated, there was a strong smell of… well kind of a mix between plastic and dryer sheets. It was not terribly unpleasant but distinct and noticeable (and I’m very sensitive to smells). If anyone else experiences this, I recommend buying a large fan for the crawlspace and using it periodically to move the air from the crawlspace out of the house and move fresh air in. (I bought a cheap contractor fan that pivots upwards and put it on a smart home remote). Over the course of a few months it dissipated and I’m thrilled to report that I don’t notice it at all now."

"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."

"Ryan proved to be a professional in every way. His gave a fair and what I felt was an on-point quote and was here when he said he would be. My front porch was cracked, caving in and separating from the house, so the present slab had to be removed and the railings around the porch as well. He was through and completely in tune with what we discussed. The whole job was done and complete in 5 days- that included curing and set up time with cement drying. Yes, I would use Ryan again and we are already discussing the next project. I found Ryan on Angi website and I am very happy he was available to do the project. Thank you Ryan!!!!"

"My rear facade wall was falling apart, there was apparent deterioration, cracks falling apart. I was recommended to High Tech by our community board. Scaffold was used for this project. They chipped out the 4-story facade and applied wire-mash. First coat of cement was for curing and the second coat was  the finishing coat. The finishing coat was very finely re-finished. The back-wall was waterproofed with thoro-coat.  My roof was leaking as well at multiple places, bubbles had been formed with water seeping in, leaving into my kitchen. The weather was very rainy and stormy at that time and thanks to High Tech they repaired my roof by placing a new layer roof on top of the existing roof and stopped the leak. High Tech remains as one of the top recommended company in our community board."

Foundation Repair FAQs, answered by experts

You’ll need to reseal the foundation every five to 10 years, depending on the sealant you’ve used, the moisture conditions present in and around your home, and the condition of your foundation. Having a foundation inspection conducted before reapplication can help you catch any problems before you begin resealing. Of course, if you notice any new leaks or other moisture problems at any time, it may be necessary to reseal the foundation sooner.

It’s crucial to hire a foundation company that’s professional, experienced, and reliable, starting by choosing local experts with at least five to ten years of experience with your type of project. Local foundation companies will understand the soil and weather conditions in your area and can carry out the best solution based on your property characteristics. You should ask for a list of customer references, read through online reviews, and check for customer complaints and unresolved issues filed with the Better Business Bureau (BBB) before hiring.

Yes, sustainable mixes and sealants minimize environmental impact.

You can buy a home with foundation issues, but understanding the extent of the problem and what solution you need is critical. If you learn that a home you’re trying to buy has a foundation problem, it’s not necessarily a deal breaker, but you should have a professional assess the issue to see how severe it is and know when to walk away from a foundation problem. Foundation issues can necessitate simple and affordable solutions or complex work that costs thousands. 

Concrete pools are very durable but can crack if not properly maintained. The most significant risk is winter weather and low temperatures when water can seep into crevices and freeze. To avoid damage, use the proper winterization chemicals, and don’t completely drain your pool. Concrete pool repairs cost around $75 per linear foot for small cracks.
