We are a service-area business, not a storefront. There is no showroom to walk into, because the work happens under your floor and over your ceiling. We serve Seattle and the surrounding Puget Sound area, from Everett in the north down to Federal Way in the south.
Most of our work sits inside the six cities below. On a map they look like one market, and they are not. The houses are different ages, on different ground, and they fail in different ways.
The short version
Seattle, Bellevue, Renton, Kent, Everett, and Federal Way are the core area, and we come to you. No trip charge to look at a house in any of them, and the estimate is free. Outside that, call and ask.
Seattle
Seattle is where most of our calls come from, and the housing stock is the reason. Ballard, Wallingford, Green Lake, Beacon Hill, and Columbia City are full of Craftsman bungalows and box houses from roughly 1900 to 1930, nearly all built the same way: a vented crawl space over bare dirt, batts stapled between the floor joists, and an attic framed in 2x4s holding a few inches of whatever was cheap that year. Ninety years on, those batts have sagged out of the bays and lie face down on the dirt, the rim joists were never touched, and the floor is cold from October to May. Lake City and Northgate ramblers have the same crawl space and a shallower attic.
Two local specifics change the bid. Access: narrow lots, steep driveways, and a crawl hatch behind a rhododendron make the work slower, and slower costs more. And older attics often still have live knob and tube wiring, which an electrician has to clear before anything gets buried.

Bellevue
Bellevue is split-level and daylight rambler country in Lake Hills, Newport Hills, and Factoria, with larger 1990s and newer houses up toward Somerset and Cougar Mountain. The split-level is its own animal. Instead of one attic over one box, the envelope is chopped into pieces: a low attic over half the house, a cathedral ceiling over the other half, knee walls, a floor cantilevered over the garage, a bedroom on an unheated garage ceiling. Every junction leaks and batts handle none of them well, which is why the standard Bellevue call is about a bonus room that never warms up. In the cathedral sections the rafters are often 2×8 or 2×10 with a vent baffle eating the depth, so closed-cell is the only way to get real R-value in.

Renton
Renton is full of small, quickly built post-war housing, especially up in the Highlands, where whole neighbourhoods went up for plant workers in a hurry. Compact one-story houses, 2×4 walls, shallow attics, often with the original insulation still up there doing very little. Fairwood and Benson Hill jump to 1970s and 1980s tract building. The issue here is ground. Many of these houses sit on the slopes above the Cedar River valley, so the crawl space is cut into the hill: one wall buried against cool soil, the opposite wall open to outside air through vents. That split in a small space is a condensation machine, and it is why we find damp framing and rust on one side only. See spray foam insulation in Renton and attic insulation in Renton.
Kent
Kent is two places and they need different work. On the valley floor near the Green River the ground is flat and the water table is high, so we find crawl spaces with standing water in them every winter. Foam is not the first move there. Drainage and a proper ground vapor barrier come first, and if we cannot fix the water we will not take your money to spray over it. East Hill and Panther Lake are a different job: 1990s subdivisions, truss-framed two-story houses, blown-in attic insulation at full depth in the middle and thinning to nothing at the eaves. Those attics usually hold the air handler and the duct run as well, above the insulation, losing money every cycle. Add the can lights and the pull-down hatch and the Kent scope is standard: air seal first, then insulate. See spray foam insulation in Kent and crawl space insulation in Kent.
Everett
Everett is a mill town with mill-town houses. Rucker Hill and the older streets near Bayside run from the early 1900s through the 1920s, plank sheathing and balloon-framed walls, so the stud cavities often run uninterrupted from crawl space to attic with no fire blocking. Warm air in a house like that does not need a hole in the ceiling; it has a chimney inside every wall. South Everett and Silver Lake fill in with post-war and 1990s stock. What makes Everett urgent is the heating: plenty of these homes run electric baseboards or wall heaters, so nothing hides the loss and every draft lands on that month’s bill. It is colder and windier up there too, straight off Port Gardner Bay. Rim joists and crawl space walls are where we usually start. See spray foam insulation in Everett and closed-cell spray foam in Everett.
Federal Way
Federal Way grew up mostly in the 1970s and 1980s and it shows: street after street of split-entry houses, the ones where the front door drops you between a half flight up and a half flight down. That shape makes two problems. The lower level is partly below grade, so the band joist sits right around grade and is usually buried behind siding where nobody has ever insulated it. And the living room tends to have a vaulted ceiling with almost no cavity depth above it. The other local factor is tree cover: mature Douglas firs shade these roofs all year, north slopes stay damp and mossy, and sheathing that never dries needs a proper look before anyone foams the underside of it. Many of these houses are all-electric, so the comfort complaint and the bill complaint arrive together. See spray foam insulation in Federal Way.
What does not change, wherever your house is
- We look at the actual house. Into the crawl space, up into the attic, with a light. No firm number over the phone, ever.
- The material suits the assembly. Closed-cell where moisture and depth demand it, something cheaper where that is genuinely the better buy.
- We will tell you when you do not need us. If a day of air sealing gets you most of the comfort, we say so and give you that number.
- We stand behind the install. Fifteen years of spray foam work in this climate, and the same person answers the phone afterwards.
If you are not in one of the six
The six cities are where the volume is, not a fence, and plenty of our jobs land in the towns in between. For a bigger job we will travel further into Washington; for a small one a long drive may not be worth it to either of us. We would rather say that than pad a quote to cover mileage. Call and ask.
Questions about where we work
Do you charge a trip fee to come look at my house?
No. Coming out to look at a house in any of the six cities is free, and there is no travel line on the estimate. You get a written scope and a number, and nobody sits in your kitchen waiting for a signature. If you are well outside that area, say so when you call and we will be straight about whether the drive makes sense.
What if I am just outside these six cities?
Call and ask. These six are where most of our work happens, not a boundary. The towns between them are normal territory, and we take work elsewhere in Washington when the job justifies the drive. The honest answer depends on where you are and how big the job is, so one short call settles it: (253) 766-5145.
Does the price change depending on which city I live in?
Not because of the city. Price moves on the material, how many inches the assembly needs, and how hard the space is to work in. An 18 inch crawl space with a small hatch in a Seattle bungalow costs more than an open basement wall in a newer Kent house, and that has nothing to do with the postcode.
Do you have an office or a showroom I can visit?
No. We serve Seattle and the Puget Sound area from the truck, so there is no address to visit. Everything happens at your house: we come out, get into the crawl space or attic, and leave you with a scope and a price. Questions before that go to (253) 766-5145 or support@seattlesprayfoampros.com.
