"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!!!"

"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!!"

"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 questions, answered by experts

Polyisocyanurate foam, or polyiso for short, has the highest R-value per square inch: 6.5 to 6.8. Polyiso is a rigid foam that comes with a reflective foil on both sides to serve as a radiant barrier. Given its high R-value, rigid foam is usually meant for foundations and basement walls.

On average, insulating an attic costs about $2,500, with a typical range of $1,500 to $3,500. The final price often depends on the attic's size, with costs generally falling between $1 to $3 per square foot. For example, insulating a 1,800-square-foot attic would likely cost between $1,800 and $5,400.

If the project involves removing old insulation, this can add an average of $900 to the total cost, bringing a full removal and reinsulation project to around $3,000.

Several factors influence the overall cost:

  • Insulation Type: Prices per square foot vary significantly by material.

  • Reflective: $0.50–$1.50

  • Blown-in: $1–$4

  • Batt: $2–$4

  • Loose-fill: $2–$5

  • Spray foam: $2–$5

  • Structural insulated panels (SIPs): $4–$7

  • Project Complexity: Factors like sealing air leaks, poor attic accessibility, and required inspections can add to the cost.

  • Removal Issues: The discovery of mold, asbestos, or pests during the removal of old insulation can substantially increase the price.

Reduces energy costs, improves comfort, and prevents ice dams in winter.

Chimney liners often benefit from insulation, though it is not always required. Insulation helps improve the liner's efficiency by keeping flue gasses hotter, which enhances draft and reduces creosote buildup. It also prevents condensation, which can lead to corrosion. Insulation is important for chimneys on exterior walls or in colder climates. Some building codes may require insulation, so checking local regulations is essential.

The average U.S. homeowner pays $1,850 to insulate their home. However, the cost of insulation depends on the type, the size of your home, and who does the installation work. 

The cost of foam board insulation depends on whether it's made from expanded polystyrene (EPS) or extruded polystyrene (XPS). EPS has the lower price point, usually costing between $0.25 and $0.50 per board foot, while XPS costs between $0.40 and $0.50 per board foot.
