    I am extremely pleased with the work that Adirondack Basements did to correct my basement issue. Had a sump pump installed a number of year ago, which is working great, so I called them this time to solve my latest issue. With all the rain this year, a crack in my foundation was created pouring water into another part of my basement, I knew who I wanted to repair it. The salesman, Larry who estimated the job was friendly and knowledgeable. No high pressure sales pitch. He recommended their FlexiSpan System to seal the crack. I was happy with the estimate and scheduled the job to be done. When Mike showed up to do the work, he quickly realized the job was going to be much more complicated than previously thought. He stayed well into the evening to get the job completed the right way. His attention to detail was exemplary and his workmanship was of the highest level. I am also happy to report that even though the job was well beyond what was initially anticipated, I was not charged a penny more for the significant extra work. Adirondack Basement is the most highly professional company I have ever dealt with and recommend them with absolutely no reservations. No one is better at what they do.

    Insulating a Crawlspace in Voorheesville, NY

    Homeowners in Voorheesville, NY had a crawlspace beneath their home that caused the upstairs area to be much cooler than it should have been. It lacked proper insulation and was damp, due to water seeping through the seams of the foundation. Since this home was newly purchased, they decided it would be most ideal to rectify these issues as soon as possible. They contacted Adirondack Basement Systems for a free estimate with one of our Crawlspace specialists. Upon doing a thorough inspection, he recommended installing both a vapor barrier and a thermal barrier along the blocked walls of the crawlspace as well as sprayfoam in the joists. CleanSpace vapor barrier is made of an inorganic material which cannot support mold growth and is warrantied against rips and tears. ThermalDry Wall is a thermal barrier made with SilverGlo technology. The reflective material keeps heat from escaping and cold air from coming through.
