Claim This BusinessAbout Northwest Weatherization
Northwest Weatherization operates from Tualatin and has specialized in spray foam and fiberglass insulation installations since 2010, completing more than 5,000 projects across the greater Portland metropolitan region. With a 4.9-star average rating from 108 verified client reviews, this contractor serves homeowners throughout the Willamette Valley, including Tigard, Beaverton, Hillsboro, Lake Oswego, West Linn, Oregon City, and surrounding communities like Sherwood, Canby, and Happy Valley. The company maintains regular business hours Monday through Friday from 7:30 AM to 4 PM and offers free estimates to help homeowners determine which energy efficiency upgrades qualify for rebate programs.
What distinguishes Northwest Weatherization from typical insulation contractors is their active assistance with utility rebate navigation, including PG&E energy savings programs and Oregon state climate incentives. Their team provides customers with detailed documentation of all completed work, including photographic evidence of insulation depths, vapor barrier seals, and pest intrusion repairs. Customers consistently note the sales representatives explained available rebate options during estimates, and several reviewers received financial incentives that significantly offset project costs.
Homeowners who called Northwest Weatherization report specific scenarios the team handled effectively. One customer discovered nearly absent attic insulation causing heating bills triple the expected amount; the crew insulated the attic, sealed crawl spaces, and reconnected HVAC ductwork that had detached beneath the floors. Another reviewer noted the installation team kept them informed throughout all project phases, while others mentioned the field representative personally scheduled appointments and followed up within the same day.
What Customers Say
All five named reviewers awarded five stars, with recurring themes: rebate assistance (mentioned by three customers), same-day scheduling flexibility, and post-work photographic documentation. Two reviews specifically praise the team's communication during installation and timely project completion.
