Services
Spray Foam Insulation
Spray foam insulation creates continuous air sealing barriers in walls, roofs, and contoured surfaces. This advanced solution improves thermal performance, reduces energy bills, and enhances indoor air quality while exceeding Super Good Sense R-Value standards. Our certified installers ensure complete coverage in new construction or retrofit projects.
Crawl Space Restoration
Crawl space restoration involves removing damaged insulation, sealing pest entry points, sanitizing contaminated areas, and installing new insulation. Our process eliminates odors, prevents future infestations, and restores structural integrity using moisture-resistant materials. We complete most projects in one day with guaranteed results.
Blower Door Diagnostics
Blower door diagnostics identify air leakage points in residential and commercial buildings. Our certified technicians use specialized equipment to measure air infiltration, provide code-compliant reports, and implement targeted sealing solutions. This service ensures compliance with Washington State energy codes and improves HVAC efficiency for reduced utility costs.
Rodent Exclusion
Rodent exclusion services combine physical barrier installation with sanitation protocols to prevent pest infestations. We seal entry points, install metal mesh barriers, and apply antimicrobial treatments to eliminate disease risks. Our comprehensive approach protects insulation integrity and maintains healthy indoor environments for residential and commercial properties.
Commercial Insulation
Commercial insulation solutions address large-scale projects with specialized materials and installation techniques. Our experienced teams handle T-Foil, pin-on, blown-in, and batt insulation systems for new construction or retrofit applications. We support prevailing wage projects and provide qualified installers to meet tight deadlines while maintaining code compliance.

Report
Ever had a honest contractor tell you that you don't need any work done? They're few and far between, and Keith with Insulation NW is one such person. He suited up and crawled around my crawlspace taking pictures for 15 minutes before returning with news that everything was in good shape. He sent me the pictures and was about to leave before I insisted on compensating him for his time (and saving me the cost of unneeded work). This was in sharp contrast to others who wanted to quote for a full replacement without seeing a thing. I'll be sure to contact Keith again if any other insulation

Extremely professional crew! I had several other companies out to do quotes and all of them tried to upsell their products, making the total project out of my price range.
Insulation NW was honest and strait forward. Getting me exactly what I asked for without trying to upsell items that I was not interested in! Thank you so much for helping us out!

I located Insulation Northwest in South King County Best Pick Reports after receiving a estimate from another company that my Instinct told me was going to be so expensive. When I called Insulation NW, I was able to get a appointment for a free in home estimate the very next day. Keith arrived happy and with a pleasant smile
to perform the Inspection. When I received the estimate from Keith, I had to look at it twice and even then thought Keith had made a mistake on the price he quoted me to perform all the work that need to be done from start to finish. I was truly amazed and the extremely reasonable

I asked for a bid for attic insulation. Keith arrived on time, with mask, shoe protectors and ladder. He was professional, respectful and an informative communicator. It turned out I did not need my insulation replaced and he (and Insulation Northwest) had the integrity to tell me the truth. I was impressed by his professionalism, honesty and kindness. SL.

On the eve of the 2021 Seattle snowstorm Insulation Northwest was scheduled to remove and replace my insulation. As a homeowner with kids I was afraid any delay would cause our family significant discomfort. Insulation Northwest not only completed the job, but they hustled and muscled calling in multiple teams for both the removal and replacement to assure the job was completed before the first snowflakes fell. The teams were polite, professional and FAST. The combined teams were great, but I especially want to thank Brandon for his expert job taping off the worksite, Ivan for providing detailed

I originally wrote a review about a problem six months ago. I wanted to update how Insulation Northwest handled it. I am replacing that old review with this new five star review:
I have been working with Insulation Northwest since they saw my original review. I am happy to report that the company wanted to make things right and have bent over backwards to do just that. Victoria Crump has been an absolute delight to work with. I hope management sees this and realizes how lucky they are to have her working for them. Jonathan, a supervisor there also was extremely helpful and cooperative. He went
