Get matched with top insulation pros in Nassau, NY

"just now True building Performance's crew did an incredible job for us. The project was to insulate our home. These guys showed up with cheerful attitudes and completed such an incredible and efficient job. From start to finish they were friendly and interacted with our family all while working in the project. The kids enjoyed watching them work. They cleaned up after themselves too which was a pleasant surprise . It was also great that we were able to get more done than we had anticipated. Originally we had elected to insulate upstairs only but we are able to completely insulate the entire house, downstairs being from the inside. They have plastic protecting their workspace from top to bottom. Joe, the lead contractor is so knowledgeable and incredibly acomodating. Paul Mendel the company's owner is the same way. A great company to do buissness with. We are just overwhelmed with gratitude and amazement at what a difference we are already noticing in the reduction of street noise from the cellulose insulation. I would Highly recommend True Building performance to anyone looking to seal air gaps and install insulation."

"The product was well provided and the product was easy to install. I didn’t have to outpunch the old insulation and I could just leave it where it was. The guys were good at what they did. Stinky but beyond that we just let air out for a while but it disappeared in a couple of days. They finished the work in one day. The quality was good and they went beyond what they promised."

"Excellent job showed up on time went over and above what was needed to be insulated."

"They did a great job. They removed the old insulation, air sealed the attic, and reinsulated to an R60 for a Great price. I would definitely recommend Travis and his team."

"Overall, excellent. We did encounter a few problems with the spray in wall insulation since the original sheet rock was just nailed in. A few sections bowed into the room. This is actually pretty common with old houses. The problem was quickly corrected, the walls properly secured, the insulation reinstalled (blown in) and the job completed. In modifications to a home, it is not always the problems you encounter, it is how you deal with them. Advance had the problem identified with a resolution that was completed within a day. Very pro-active!"

"I was lucky to come across this company on home advisor, Michael, Devon, and Shane exceeded my expectations. They were quick and professional. These guys treated mold and replaced the insulation in my new home, and went as far as removing all of the junk left by the previous owners. My crawl space looks like a completely different home within the week it took them to complete the job. I couldn't have asked for a better job, and I intend to mention them whenever I hear someone in need of work!"

"They were great and did the job quickly and on time. The house has never been warmer, saved me money. Cannot recommend highly enough."

"Excellent experience from start to finish! The home energy audit showed me where I was losing heat and areas that needed attention. Getting the house sealed and getting blown in cellulose and an attic cap installed professionally is something I would recommend to any homeowner. Expediant energy came to install it soon after the initial estimate. which in this winters bitter cold temps is something I really appreciate. I Noticed the difference immediately. Anyone who is paying for heat and looking to improve their insulation should give these guys a call you won't regret it!"
