"Had my attic cleaned and R30 Batt insulation installed. Work crew was excellent. Worked diligently in 95 degrees heat. Rodent proofing all around the attic including the crawlspace. Customer service was so-so, got routed to NJ, who didn't know what were the issues with my current project. Overall excellent work."

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.
