"They were very professional, took care of helping me get the home energy audit and the rebates for attic and wall insulation. Also improved attic ventilation installing soffit vents and baffles. We got three estimates and they were a very good price, but the service is what sold us."

"Highly professional and extremely accommodating. There were bats in my attic when they went in to redo the insulation. They calmly (as they could) told me the situation and came back at a later time with no added cost. Did an excellent job, and had a incredible attitude throughout. Cannot recommend enough. Thank you!"

"I liked that the first questions we were asked was "Have you had a home energy audit done? Did you know you can get a rebate on your insulation project?" Before even knowing the scope of our project, they were looking to help make it more affordable for us."

Insulation FAQs, answered by experts

At a minimum, blown-in insulation lasts 20 to 30 years. Cellulose and sheep’s wool come from natural materials, so they likely max out at around 30 years. Fiberglass and rockwool feature artificial materials that boast lengthy lifespans, up to 50 years, or even longer in some cases. As always, this timeline assumes you don’t run into any issues, such as flooding or mold, that shorten the lifespan.

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.

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation: 

  • If the insulation is over 15 years old

  • If the insulation is wet or moldy

  • If it is vermiculite insulation

  • If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.

Yes, many professionals offer insulation options, such as insulated siding (including insulated metal siding), to improve your home's energy efficiency.

Insulating a detached garage won't reduce your home's heating or cooling bills—and insulating an attached garage will only have a small effect on your home's energy efficiency. However, insulating an attached garage can reduce the transfer of heating and cooling to and from the outdoors, which can reduce the amount of energy your home needs to stay comfortable. Also, having an insulated garage is just more pleasant. Balance the cost of insulating your garage with how you'll use the space to determine if the project is worth it.
