"This company came in a updated our 40-year old home insulation with new R-38 batting. We were impressed how much attention to detail the company has for removing old insulation, clean-up, disinfection, and installing new insulation. They also replaced a damaged dryer vent in the crawlspace. Nico and Jeremy were a great combo to work with from quote through install. I plan on calling them back in spring for another project."

Customers say: True professional

"Moshe and his team at Attic Kings are amazing! When I contacted them, they got back to me almost immediately with a date and time for an estimate to install insulation. Moshe was very communicative, texting and calling to let me know when he would arrive. On installation day, Moshe made sure to keep everything as clean as possible, and everything went incredibly well. They are all so kind--would definitely hire again!"

"The sales rep, Bryan, went above and beyond to answer all my zillion questions and concerns. He was responsive, knowledgeable and shared his expertise in not only insulation, but all in LED canned lights and dimmers. He was amazing and I would only ask for him again. I plan to refer others to him also in the near future. The installers were good too, letting me climb the ladder and look at the work, cleaning out the old insulation and advising me they found no termites or rodent droppings. I wish they would have vacuumed the bedroom where they brought in a lot of dirt on the carpet, and also used the shop vac in the garage afterwards, as I had to clean up afterwards, which took me an extra hour. However, overall, I was pleased."

"We had an inspection and we had to replace the insulation in the attic. We were able to get a good deal from this company after we reached them via a referral. 
The work that they did was very good and professional. there were several employees at the house for the 2 days work that they did. We do recommend this company for any insulation replacement that you may need.

Insulation questions, 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.

Insulating your home's exterior walls can realize up to a 20% reduction in your monthly energy bills. This means that regardless of how much the project costs, it can begin to pay you back immediately. Additionally, adding spray foam and other high-end materials can increase the selling value of the property.

For standard 2x4 walls, the ideal insulation has an R-value between R-13 and R-15. This level of insulation, typically around 3.5 inches thick, fits well within the wall cavity. Common options include fiberglass batts and spray foam. The best choice for your home can depend on your climate; use R-value maps, like those from Energy Star, to determine the recommended level for your region. For colder climates, you might also consider adding exterior insulation for greater efficiency. Always check with your local building codes to ensure you meet any required standards.

Faux wood garage doors provide the best insulation for garages. This style is commonly insulated with polyurethane foam—a thermal conductor—that retains heat and keeps you and the inside of your garage warm.

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.
