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."

"What an amazing experience! It is very rare to find a business with a group of people who are as knowledgeable, personable, professional, and reliable as the family who owns The Climate Chief. I am one of those customers who really do their homework, from buying toasters to installing insulation and everything in between. I also ask a LOT of questions. (Not all vendors love that!) It took me a couple of weeks to find a company that could provide the exact solution I needed for my home. I use the word solution because they did not just say, **Here is the insulation we sell. This is the cost** They actually took the time to evaluate my entire attic and home to find the combination of things that made the most **big picture** sense. I have never received such a comprehensive written proposal from ANY other company in all the years I have lived Upstate. They also gave me a list of add-on options and explained the combinations. I could take all of them or none of them. At no time was there any **upsell** technique or the famous **let me call my manager** nonsense that you often get from service providers. They contacted me with a detailed email the night before the start date to let me know when they would be arriving, who would be on the team, exactly what they would be doing, and how long it would take. Wow. It was so refreshing to communicate with professionals who answered all of my questions and actually welcomed them before the project began and during the installation. I had a specialized attic project that required a lot of expertise. I felt very confident in their abilities for the entire length of the project and would highly recommend Mark {father, founder), Gary {initial consultation/evaluation, son), Bill (job foreman, another son), and the whole team at The Climate Chief. In addition, even though their proposal was much more comprehensive than any other, the quote was not only fair but extremely competitive. I feel so strongly about their work ethic that I authorized the company to give my contact info to potential customers. It is so nice to find a trustworthy local business that I can share with others in the community."

"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."

"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!"

"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

In addition to adding insulation to your attic, you may want to add a radiant barrier. A radiant barrier works by using reflective material, such as foil, on the attic floor. As heat penetrates the roof and enters the attic, the radiant barrier reflects the heat upward and back through the roof. If you receive a lot of direct sunlight on the roof, using both a radiant barrier and insulation in your attic can provide significant benefits.

How to dispose of insulation depends on a few factors, including the condition of the material. While you can simply bag up and throw away many kinds of insulation, some municipalities offer recycling, so it's worth checking with yours. If there are contaminants such as asbestos in your insulation, abatement and specialized disposal are often necessary.

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.

You won’t find anything inside a cupola on a house because it’s hollow (think of an upside-down cup), allowing air to ventilate out of a roof via vents and light to come in via windows. They also usually have a base, vents around the middle (usually louvers), and a pointed cap at the top.

The cost to install a radiant barrier ranges from $700 to $2,800, depending on the size of your roof and the type you choose. Most people pay an average of $1,700 to install a radiant barrier. Foil options, both single- and double-sided, cost between $0.10 and $0.90 per square foot, while spray-on options start at $0.60 and go all the way up to $1 per square foot—which can add up quickly.
