Mini Case Study: A Warmer Bonus Room Near the Lighthouse

A Mukilteo family called us about a bonus room that swung from freezing in January to stuffy in July. Cascadia Spray Foam of Seattle inspected the attic and wall cavities, then sealed the space with closed-cell spray foam from top to bottom. The room now holds a steady temperature in every season, and the furnace cycles far less often. The homeowners told us it finally feels like a real part of the house.

Got Cascadia Spray Foam Insulation to take care of my in-laws place up in Seattle. The house was older and had some serious drafts, especially in the winter. The crew came out, did a full walk-through, and explained exactly what they were gonna do. Super professional and easy to work with. The difference after the spray foam was like night and day. The house stays warm now without the heat running non-stop. My in-laws are beyond happy and I’m glad we called these guys. Definitely recommend.

Mukilteo Spray Foam Insulation Questions, Answered

How well does spray foam hold up against Mukilteo's damp coastal winters?

Very well. Closed-cell foam resists moisture and seals air leaks, which is exactly what Western Washington buildings need through the long wet season.

Can you insulate older homes near the Lighthouse and Old Town neighborhoods?

Yes. Our team regularly upgrades insulation in older Mukilteo homes and works carefully around existing framing and finishes.

Do I need to leave my home during spray foam installation?

We ask everyone and pets to stay out of the work area while the foam is applied and cures. Most homeowners are back to normal use shortly after the work is complete.

What is the difference between open-cell and closed-cell spray foam?

Open-cell is softer and helps quiet rooms, while closed-cell is denser and adds moisture resistance and rigidity. Our team recommends the right fit after seeing your project in person.

Besides Mukilteo, which nearby areas do you serve?

We serve Everett, Lynnwood, Edmonds, Mill Creek, and Bothell, along with the surrounding Snohomish County communities.
