Our Insulation Services

Northwest Weatherization offers a comprehensive range of insulation services tailored to meet the needs of both new and existing homes.

Attic Insulation

Attic insulation is one of the most important factors in maintaining energy efficiency. Because heat naturally rises, inadequate insulation in the attic can lead to significant heat loss and higher energy costs. We install fiberglass insulation, blown-in insulation, and cellulose insulation to help regulate indoor temperatures and reduce strain on your HVAC system. We also perform air sealing in the attic to prevent conditioned air from escaping.

Insulation Installation

Our professional insulation installation services are ideal for new construction and remodeling projects. We install a variety of home insulation materials based on your home’s structure and performance goals. Proper installation ensures the insulation reaches its intended R-value and performs effectively for years to come.

Insulation Replacement

Over time, insulation can settle, become damaged, or lose effectiveness. Our insulation replacement services include safe insulation removal and installation of upgraded materials. Replacing outdated insulation can significantly improve comfort, indoor air quality, and overall energy efficiency.

Crawl Space Cleaning

Crawl spaces often contribute to moisture issues, air leaks, and poor indoor air quality. Our crawl space cleaning services include debris removal, insulation removal when necessary, and preparation for improved moisture control. Maintaining a clean crawl space supports healthier air and better home performance.

Vapor Barrier Installation

Moisture control is critical in many Pacific Northwest homes. We install vapor barriers in crawl spaces to prevent ground moisture from rising into the home. Vapor barrier installation helps reduce humidity, protect insulation materials, and improve long-term durability.
