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."

"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!!"

"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!"

Insulation questions, answered by experts

Unfortunately, pipes can freeze when exposed to prolonged freezing temperatures, whether or not you have installed insulation covers. Insulation covers, however, are still an excellent idea as they can reduce the chance of your pipe freezing by keeping the pipes closer to the temperature of the water inside the pipe.

Three signs that you need crawl space insulation are drafts, high energy bills, and mold. Drafts can start in crawl spaces and cause hot or cold air to spread to the rest of your home through holes in the floors and walls. And even if your entire home is well-insulated, you can still feel an unchecked draft from your crawl space and in your utility bill. Uninsulated crawl spaces can let in air and moisture, and because they’re built directly on the ground and difficult to dry out, they are hotspots for mold and mildew.

Yes, many services include adding insulation for energy efficiency. Confirm with your contractor.

The most affordable way to insulate a garage involves choosing cost-effective materials like fiberglass, which comes in batts or rolls and is relatively easy to install. You can often install this type of insulation without needing to add drywall, which helps reduce costs. While a DIY approach might seem cheapest, hiring a professional installer can be highly cost-effective. Experts can accurately determine your garage's specific insulation needs and ensure the best results for your investment, often using batt insulation for the bulk of the project.

To cover your HVAC ducts and air vents during construction, use plastic sheets or drop cloths secured with painter's tape. Be sure to cover all supply vents on your floors and walls, as well as the larger HVAC return vent, which is typically on the ceiling. While canvas drop cloths can also be used, they may not catch all the fine dust. It is crucial to shut off your HVAC system or at least the zone where construction is happening. Running the system with vents sealed can put significant strain on the blower motor and air handler. For additional dust containment, you can also hang plastic sheets over doorways to separate the construction area from the rest of your home.
