"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."

"THESE GUYS ARE AMAZING! Our new porch looks perfect!!!! They got back to us very quickly, and after we agreed on the project spec's amd pricing they got right to work. Our old porch was down and our new one was up in just a little over a week. They were even able to repair our leaky side roof! These guys were friendly, professional and very neat. They also offered us financing options which was to have. I would recommend these guys to anyone looking to have some home improvements done! We will totally be using them again!!!"

"Justin is a true professional and his crew go above and beyond to complete the job. While spray foam insulation is not cheap I feel that the job I received will pay dividends years to come. Justin is deeply committed to his community and I work beside him every year as volunteers to build our ice palace before winter carnival. His ethics are shown thru this work and it translate into his business. Thank you. dave"

"We have had them for about three years and we have also been very satisfied. They have been responsive to us. Once we had a snake in the basement and I did not want to deal with it, I called them. They could not help me, but they referred me to somebody else who did."

"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!"

Insulation FAQs, answered by experts

Yes, PEX pipes should be insulated in certain situations. While insulation is not always necessary for pipes running through insulated interior or external walls, it is recommended for any pipes located in uninsulated rooms, unheated areas, or outside, especially in regions with cold winters. The primary reason is to prevent freezing. Although PEX is more resistant to cracking from freezing than other materials, repeated freezing and thawing can weaken the pipes over time, increasing the risk of a burst.

Heat lost through uninsulated basement walls can account for up to 30% of the total energy lost through heat transfer to the outdoors. While homes in mild climates won't gain as much benefit from having an insulated basement as those in cold climates, the effects are still noticeable on your energy bill.

Closed-cell foam may come with a higher price tag, but it’s worth the investment because of its strength and durability. This material offers excellent thermal and moisture resistance, contributing to its long life span. Its construction enhances energy efficiency, which can lead to reduced heating and cooling costs over time.

Garage door insulation can last anywhere from 20 to 100 years depending on the type of insulation. Cellulose has the shortest lifespan coming in at between 20 and 30 years, while spray foam, mineral wool, and fiberglass can last between 80 and 100 years with proper maintenance. 

Humidity plays a role in how long more susceptible insulation materials—like fiberglass—last. Once fiberglass batts reach the 15-year mark, you'll need to routinely inspect your insulation to ensure that it is in mint order.

The cost to rent an insulation vacuum ranges between $250 and $350 per day. The price will increase if you choose to rent for additional days, but you may get a discounted daily rate if you rent it for a whole week, which could cost up to $1,000. Once you've removed the insulation and are ready to replace it, the cost to rent a blown-in insulation machine ranges between $100 and $500.
