Customers say: True professional

"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 team from The Climate Chief were very professional from day one. They laid out plastic sheeting to protect our recently refinished hard wood floors. Cleaned up any messes from the blown in insulation. Covered the doorway by utilizing TEVEC house wrap and tape so we would not lose much heat when the hoses were running. At the end of each day one of the employees would pick up the plastic sheeting and sweep the floors and they would pick up all the tools so not to leave a cluttered workplace inside and outside. Billy Mike, and crew were very happy and cheerful while at work. Very knowledgeable about how to seal up any of the existing open areas. They removed all the existing fiberglass insulation before replacing with 18 inches of cellulose R60. A very professional job we are very pleased to say. We noticed a warmer difference in room temperatures right away! We would strongly recommend them to others!"

"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."

"They removed old moldy insulation, sprayed fungicide on the mold and encapsulated a crawl space. Also insulated with foam insulation around the entire basement rim joist, including the crawl space. They were on time and finished before they expected to. During the inspection, when I pointed out bubbles in the foam, they redid that section without question. Zy called after they finished to make sure I was satisfied."

"Asked for a quote on removing an old deck, replacing with a larger one. Price quoted was fair, and we accepted. We're very pleased with the final product, and the whole ordeal was hassle-free for me and my wife. Every worker involved was very professional. Communication from start to finish was excellent, and I feel the job was completed faster than we had expected. Will be using this company in the future for other projects."

"Matt was exceptional. He did a great job. Mice in the attic. He secured the areas outside where the mice were getting in. Then he set traps and replaced a vent in the attic. His price was very reasonable and he offers a warranty. I would highly recommend Matt from Got It!!"

FAQs for insulation service projects in East Nassau, NY

Local and federal rebates are available for insulation installation, which can significantly reduce your overall costs. Many utility companies offer incentives or rebates to homeowners who improve their home's energy efficiency. Contact your local energy provider or government agencies to learn about available programs in your area, and consult with a professional insulation installer to maximize your savings.

It's not necessary to remove old insulation before adding new insulation, as long as the existing insulation is in good condition—dry, free of mold, and not damaged. Adding new insulation on top of old insulation can improve your home's energy efficiency by increasing the overall R-value. However, if the old insulation is wet, moldy, or damaged, it's best to remove it before installing new insulation to prevent potential health risks and ensure optimal performance.

Insulating a house takes between five and twelve hours for batts or boards, and two to five hours for spray foam or blown-in insulation. The exact time depends on the size of your home, the type of insulation, and the accessibility of the areas being insulated. Keep in mind that projects may take longer if old insulation needs removal, if there's a larger square footage, or if spaces are difficult to reach.
