"⭐⭐⭐⭐⭐ 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!"

"I am very happy with landscape work I had recently had done by G & G Landscaping. I had large evergreen bushes and a tree removed from along the front of house. They replanted the area with some smaller plants and added fresh dirt t to the area. I also had them lay some rocks out along the foundation of the back of my home and in front by the electrical boxes, with some additional plants there as well. I was happy to have this project done and they were able to complete it all in one day."

"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."

"Chad came over on a Friday to give me an estimate on a foundation repair on my garage which faced my pool. He knew exactly how to fix it and said he could do it the next day since it was a relatively small job. He came over the next day with his son and they both got to work right away. They were both very friendly and very easy to talk to and work with. They completely repaired the garage wall as well as filled in some cracks on the concrete around the pool. He also gave me an easy fix for another small repair on my patio. They took something that was an eyesore and made it look brand new and also protected the structural integrity of the garage. His work also comes with a 2 year warranty which gives peace of mind. Chad and his son were a pleasure to work with and I will definitely call them again for any other masonry project or repairs I have in the future!! Thank you very much!"

"I recently bought a 1968 ranch home. The front and back porches and areas of the foundation were in dire need of major repair and resurfacing. I also wanted a color stain applied to the porches and the foundation when the masonry was complete. From my initial conversation with Serena, to the very detailed estimate, and throughout the job to completion, I was very happy with the timeframe and the quality of the work. Serena and Bo answered my many questions along the way. They were a pleasure to deal with; and, I am very happy with the outcome. I learned a lot about masonry from my many questions and their thorough responses. This is a family business that exhibits an attention to detail, honesty and to customer service that is hard to find these days. I realize that my project was small compared to their usual scope, but I was treated with professionalism nonetheless. I would not hesitate to recommend them."

"I'd had a evaluation and estimate from Exterior Solutions and after then not having received a call back or return email (the inspector had also pulled a loose single from my roof leaving it exposed) I went back to Angie's List. T&T came up, noting it had a good rating, I called. Dave and a colleague arrived, evaluated the roof and offered to repair it free of charge. Still blown away by this. A member of their crew arrived yesterday and did this; apparently they've ended up correcting other work done by Exterior Solutions and they only wanted the good will rating for the work. Incredibly nice and very professional."

"I was concerned about the cracks on two patios and a set of steps. Figuring I needed them lifted and resurfaced. Jim came out conducted a full inspection and told me the honest truth that I could spend the money to have them come in and do the work, but this really was something that was more suited for a DIY situation as long as I felt comfortable with some basic tools and abilities. If I got in over my head they would certainly come and fix everything but for the time being and the cost of materials, this was something I could handle. I can't express how refreshing it was to have someone honest come into my home and not treat me like an idiot and take advantage of a situation. HONEST!!!"
