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!"

"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."

"Jason is a busy man, which made communication tough at times, but he was always polite, informative, knowledgeable, and honest. He and his crew did wonderful work, he went out of his way to accommodate a number of requests, and the price he gave me was nothing short of awesome! I would recommend him to anyone in need of insulation."

"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!"

"From the moment we met nick we felt comfortable. After my gf got taken for money from a contractor we were a little hesitant on trusting anyone again.. Nick gave us a quote for the job that we were very happy with. And insured us we would be very happy. And wow were we, nicks crew was amazing , friendly and cleaned up everything when do e. Can't say enough about nick and his team. This is how a business is supposed to be run. Don't even bother calling anyone else. They did an amazing job on our building and more importantly? Welcomed us like we were family during the process... 100 thumbs up. Chris and Christina"

Insulation FAQs, answered by experts

One of the clearest signs that your insulation isn’t working as well as it should be is a noticeable difference in temperature throughout your home. One room might feel icy while another is hot as Arizona—this indicates that some parts of your home are either retaining or losing heat more than others. Additionally, a sudden increase in your energy bills, evidence of pests or rodents, or evident water damage are other signals that warrant a thorough inspection of your insulation and potential replacement.

To keep cold out, look for treatments that sit close to the window frame and are made from thick, insulating materials. Thermal curtains, cellular shades, window quilts, and insulated shutters can all help retain heat. Layering window treatments, like pairing lined curtains with cellular shades, can provide even better insulation by further reducing drafts and heat transfer.

R-value stands for resistance value and is a number assigned to insulation that states how good the insulation is at heat transference (insulation). The R-value of injection foam is around 4 which homeowners will be happy to know is actually quite good. Another benefit of injection foam versus fiberglass foam is that the colder it gets, the more injection foam retains its resistance properties, whereas fiberglass tends to lose its efficiency in colder temperatures.

Yes, even though frost-free and freeze-proof faucets are designed to withstand winter weather, it is still recommended to cover them with an insulated cap, especially during periods of extreme cold. These faucets work by keeping excess water inside the home's heated space and using a downward slope to drain, but this protection can be compromised. For the faucet to work correctly, you must always disconnect any attached hoses before temperatures drop below freezing, as a hose can trap water and lead to freezing. Ultimately, covering all outdoor faucets, even freeze-proof models, is the best way to prevent frozen and burst pipes.

Spray foam insulation doesn’t do well around heat sources. Therefore, You can use spray foam insulation to seal around HVAC boots that penetrate through the drywalls or around where wrapped ducts connect to the boots, but we don’t recommend using spray foam insulation to encapsulate your air ducts. Spray foam insulation on air ducts is also less effective compared to duct wraps.
