Washington 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 King, Snohomish, and Pierce Counties.
Had RetroFoam come to my house yesterday. Professional, efficient and cleaned up afterwards. I asked them for a quote on the spot to add my detached garage (which theu did), and they were able to do it the same day as my house. Price is very reasonable and I could tell a difference my first night.

Neil and his team promised that I’d be blown away with how much warmer my house would feel. I was a little skeptical but knew something would be better than nothing. My home was built in 1957 and had zero insulation in the walls. I noticed a difference the first night. First thing I discovered was the furnace wasn’t running all evening to keep the house warm. The next morning I was even more blown away by the way my home now keeps the heat in. I always turn the heat down to 62 at night and the furnace still runs at night. I woke up and the thermostat said 64 degrees. Not only is my home warmer but it’s going to save a tremendous amount of money with my gas bills in the winter. So happy!

A pleasant experience in a time where most contractors fail to measure up. Neil and his employees came to my house, focused on the task and did professional level work on a house that was anything but easy. Thanks guys!!!

Our house was built in 1919 and needed to be insulated. I got ahold of Washington RetroFoam and was delighted with everything they did. When they came to do the walkthrough I was informed of a couple money saving offers. I gave them a copy of my PSE bill and they filed the paperwork work for that one.
Since our house is so old, asbestos siding under the new vinyl siding, they had to install from inside the house.
On the morning of the foam-in, they arrived on time and they worked like a well rehearsed unit. It was reassuring to see that each worker knew their assignment and they performed it well.
We do have to do some work in a couple days after it’s all dry and set, to paint the holes the foam was inserted through the walls.
I know this we’ll be feeling the benefits of the installation this winter and upcoming summer.
It was a good experience and will recommend Washington RetroFoam to anyone looking for this type of need.

They did a great job insulating my home. They were professional and quick. The owner was able to get us instant rebates for having no prior insulation, making the cost much more affordable. Great experience and I recommend them to anyone
