Attic Insulation & Air Sealing Contractors & Services In Your Area

  • Comfenergy

    "I am so impressed with Comfenergy. The sales rep explained why we only needed to improve the insulation at the top of our unfinished basement walls, not the whole thing as another company recommended. So it was considerably less money than we thought we’d need to do the job. Brent and his assistant arrived on time to do the work and were so quiet that we weren’t inconvenienced in any way. I definitely recommend this company. "

    Shiner Roofing Inc.

    "this project has not yet started, however, David, from Shiner was THE MOST THOROUGH salesman we've had out so far. He went far and above what any of the others did (and we had 7 total), including getting up on the roof, taking tons of pictures, and covering every aspect of what they are going to do and what we should espect. We expect to start this project in about a month, but we will be choosing Shiner for the job!"

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.
