Attic Insulation Companies Near You

Attic Insulation & Air Sealing Contractors & Services In Your Area

Attic insulation keeps heat energy in your house. Without enough insulation, up to twenty-five percent of your home's heat loss could be escaping through the roof. This can make your energy bill skyrocket in the winter. It also affects the temperature in your home. The upstairs and attic have less protection from the elements so it's colder in the winter and hot in the summer.

Find attic insulation contractors who can get your attic covered. Local professionals know which levels of insulation are best for your region. Look for attic insulation services that install high-quality insulation and:

  • Remove water-damaged or infested insulation.
  • Protect your investment with moisture guards.
  • Insulate the nooks and knee walls in your attic instead of only between the rafters.

Good attic insulation can lower your energy bill. It can also reduce noise and make your home's temperature more consistent. Type in your zip code and HomeAdvisor will find attic insulation installation companies in your area.


"They draped the carpets and the drop from the 2nd to 1st floor to keep any stray fiberglass from the house. The attic is sealed (small holes) and full of insulation. Soon we'll see how it helps with the cold."

"We are very happy with our decision to use USA Insulation for our attic. They called the day before to remind us when they would arrive. They arrived on time, did a great job, answered our questions, and cleaned-up prior to leaving. "

"Had recently bought a new house and our home inspector found a nest in the attic. We weren't sure if anyone was still using the nest and home advisor recommended Environmental Pest Control for us. The service was great - very transparent which I always appreciate! We had an estimate within a week of contacting them and Patrick was very thorough with the inspection and explanation, making sure I understood what the problem was and how it would be fixed. We ended up having mice in our attic along with the bird nest and Brett came out to remedy the problem the following week. The fix was quick (about an hour or so) and Brett was very thorough as well, checking in with us throughout the process to keep us updated on his findings and removal/sealing process. We'll be keeping up with quarterly check-ins and feel very comfortable in our home now. The whole team is very friendly (& great with dogs!) and we would highly recommend them."

"Not inexpensive, but worth the cost for energy savings and efficiency. We had received a much higher bid from another company, and were glad we chose Comfenergy. The technician was very knowledgeable and we felt a great difference in our upstair master bed and bath which were uncomfortably warm prior to the improvements. Also nice now to have "green" home for resale."

"I would recommend these guys to anybody. This guy started at 8:00 and worked until job was done at 4:00. He installed 11 windows. The installer knew how to do his job. The rest of the people who helped put this job together are great to work with and told me about every part of the job. They explained every detail of the window and how it would be installed and how to work it. "
