Eco-Therm Insulation is a family-run insulation company based in Arlington, Washington, serving homeowners and builders with a focus on quality, honest communication, and personal service. The company aims to build lasting relationships and provide practical solutions that balance performance and cost. Its services include home insulation, insulation for new construction, and blower door tests.

Certified installers use high-quality, environmentally friendly products to help weatherize homes and reduce energy bills. During blower door testing, the team depressurizes a home to identify and seal air leaks, helping limit drafts and support long-term utility savings. Eco-Therm also provides air sealing and energy audits, with an emphasis on improving a home’s efficiency.

The company is led by owner Keith, who brings more than 30 years of experience in the insulation industry and works with a small, close-knit team. Based at its Arlington office, Eco-Therm invites customers to discuss their projects by phone or through its website
