Cascade RetroFoam understands that your home is a big investment and you don’t want to waste time and money dealing with an uncomfortable home and high energy bills. RetroFoam is a tripolymer based resin that creates an odor-free, non-toxic foam insulation that creates an air seal. This injection foam doesn’t off-gas, is Class One Fire Rated, and safe to have in your home. It is an excellent fit for existing exterior walls and can be installed outside the home. Insulating an existing home with RetroFoam is one of the best ways to make your home more comfortable, lower your monthly energy bills, and reduce your carbon footprint. We service areas of Washington, Oregon, and Idaho.
Neil (new owner) was very responsive. I had Cascade RetroFoam out in 2022 to fill my empty walls. At the time, they did a fine job, keeping it mostly clean--I didn't observe them installing but the result was a more comfortable home during the winter. However, when I removed the siding on the house in June 2026, I found several missing stud bays. I contacted RetroFoam right away and Neil responded within a day. He was incredibly responsive, coming out the following day with his crew. He made sure that EVERY nook and cranny got filled. I was very impressed with the integrity of his response--humble, curious, and prompt. It shows that he actually cares about his customers and product. His exact response was, "you get what you pay for" and I really did. I would recommend RetroFoam to anyone in the area as a FIRST option, not a last. There are very few companies left that are willing to stand by their work and Neil and RetroFoam do just that. Excellent work guys!

I had great experience working with Neil and the team. They showed up on time and were able to knock out the job in just a single day. I am excited to see how the insulation performs over the summer and winter seasons. Thanks again!

Reached out to Cascade RetroFoam about an insulation issue and it turned out my project wasn't a fit for what they do.. and honestly, how Neil handled it was refreshing. No trying to stretch his service to make a sale, no vague runaround. He was straight about what they handle, and then went out of his way to connect me with the right partner for the work I actually needed. In a trade where you brace yourself for the upsell, that kind of honesty is rare, and it says a lot about how this firm operates. When I get to a project that's in their wheelhouse, they're the first call I'm making.

I own a small business and we were struggling with noise travelling between rooms/walls. The team at Wasington RetroFoam gave me a great quote over the phone and got us on the schedule in under 2 weeks (for a Saturday instal). The team showed up early, worked effeciently and got done early. We noticed the improvement in the rooms right away. I'm thrilled that we got the opportunity to work with them. Thanks!
