I'm so pleased we went with Specialty Insulation NW! Pam at the office was super responsive, friendly, and professional. When I first contacted them seeking information about spray foam insulation, Jimmie called me personally and told me about the product. I had previously had insulation man-splained to me by a competing company, so it was refreshing to be treated respectfully. We had the walls and ceiling of our basement spray foamed and were happy to discover that they also did the underside of the stairs! Also, we had a permitting delay the day before they were scheduled to work and they were very accommodating to reschedule. Once we called them with the "ok to proceed" they got us back on schedule for the very next business day. Amazing!
I would recommend anyone to Specialty Insulation based on my personal experience.
Jimmy did an awesome job applying closed-cell spray foam to my entire house! It made all the difference - I'd recommend this to all who are replacing insulation.
I got several quotes for spray foam insulation underneath my 30 year old house. We live in a rambler with a fairly large amount of floor space so it was going to be expensive. I reached out to Jimmy and he gave me a very competitive quote and was very friendly throughout the entire process. He educated me about what type of insulation would work best for me and when the crew showed up, they did a fantastic job!

Here are some common questions we hear from our Seattle area spray foam insulation customers.
The cost of closed-cell spray foam insulation depends on the size of the project and how much material is required. On average in Western WA, it can range from $2.50 to $5 per square foot and inch thickness. Every situation is different, which is why we provide free estimates to give you clear, upfront pricing before work begins.
Yes. Closed-cell spray foam delivers a high R-value per inch, creates an airtight seal, and resists moisture. For Puget Sound homeowners, this means lower energy bills in both summer and winter, better comfort, and protection against mold and dampness. It also lasts longer than traditional insulation, making it a smart investment.
Closed-cell spray foam expands about 1 inch for every pass. Unlike open-cell foam, it is much denser, forming a rigid, durable barrier against heat and moisture. This controlled expansion allows our team to apply it precisely to walls, attics, and crawl spaces for maximum efficiency.
Closed-cell spray foam offers an R-value of about 6 to 7 per inch, one of the highest ratings of any insulation. This means it delivers superior thermal resistance in less space, helping homes across Western WA stay cooler in summer and warmer in winter while reducing energy costs year-round.
Thickness depends on where it’s installed. In most crawl spaces and walls, 2 to 3 inches of closed-cell spray foam is enough for strong air sealing and moisture protection. Rooflines and attics often need 4 to 5 inches to meet recommended R-values for our climate. Our team installs the right thickness for your home to meet code and comfort needs.
