Insulation Contractors in Sammamish, WA

"We had mold and rodent mitigation services performed in June 2024, in addition to new attic insulation installed (both batts and cellulose), plus removal of our old insulation. The team (Phillip and Troy) were very responsive, they completed the whole project in one day (even though I was expecting it to take two days), and they provided some nice extra touches like adding a platform in the attic that we could use for storage and adding some extra batts at no extra charge to several parts of the attic that we hadn't planned on. Even though the company is relatively new, they have been doing insulation, mold and rodent mitigation work for many years and it's clear when talking with them that they're knowledgable and very focused on excellent customer service. Highly recommend!"

"The lake atitlan, insulation team just finished replacing our old blown in insulation in our attics with white R-38 rolled batt insulation. Overall, we were very happy with their work and attention to detail. Everything was spotless when they left. They were also a few thousand dollars less expensive than a bid we got from a larger local chain. The old insulation was blocking the soffit vents (under the gutters) allowing moisture and black mold to develop on the underside of the roof sheeting. First, they built a plastic tunnel from the front door up to the upper attic access door in the top of a closet near the bedrooms. This prevented any debris from the job filtering into the house as well as protecting the carpet. Next, they removed all the old insulation with the assistance of a giant vacuum. The black mold on the underside of our roof sheeting was treated and the new insulation installed. It now looks like a field of freshly fallen snow up there and no blocked vents."

"We had floor, attic, duct sealing, Joist, and garage wall insulation done. The insulation job Performance did was amazing and what a difference in efficiency and comfort in the house since we had that done! From the first conversation with Ian, to the tidy & expert execution of the huge job, we were totally satisfied. Of all the remodeling projects we have done, this was the best decision we made! We gladly recommend Performance without hesitation!"
