Customer Reviews, Testimonials and Case Studies

Steven V. of Sammamish, WA – I had Eastside Insulation completely overhaul my crawlspace, and could not be more pleased with their service.  Roberto and Isias showed up, and in one full day of work they removed all existing heat duct insulation and old vapor barrier, applied 2 inches of spray-on foam below my kitchen where I have multiple vents and pipes go through the floor, applied spray-on foam below my fireplaces, sealed all heat duct joints with mastic, installed new insulation on all heat ducts and water pipes, added new insulation along the entire crawlspace floor and tied it neatly with nylon string/rope stapled to joists, then cleaned and vacuumed the entire area, and finally placed new 6 mil black vapor barrier.

I was very impressed with how professional, hard-working, attentive to detail, and downright pleasant this crew is.  They are top notch and absolutely know what they are doing.  I would hire them again in a heartbeat.  Highly recommended.

Kelly M. of Issaquah, WA – What a great find! I had been researching a good insulation company for the older home we purchased and was fortunate enough to find Eastside Insulation while I procured bids.  Kevin of the Woodinville office spent a long time with us, thoroughly inspecting the attic and discussing current code and his expert recommendations. He was extremely knowledgeable, courteous and the bid was less than others who performed quick 10 minute inspections and guessed on some things. The expertise and competitive pricing is a great combination.
