Spray Foam Genius Marketing helps spray foam and insulation contractors in Seattle, Washington win more jobs from homeowners and builders searching in that market. Spray foam marketing in Seattle, Washington should follow the climate and the housing stock you can actually cite. The climate zone on this page is 4C. The population line reads 784,777. The cards under the reading are the citations.
Degree days on this page: 4,376 heating and 265 cooling. Both figures use base 65 F. The heating note says the reading was measured at SEATTLE TACOMA INTL AP, WA. Heating (4,376) is larger than cooling (265). Pages and ads can lead with cold rooms, drafts, and heating bills. Those are the published normals, not a forecast for a given year.
Zone 4C is the climate designation published for Seattle. The moisture letter on this zone is marine (4C). The accompanying note is "marine climate, zone 4 of 8". Source on this page: U.S. DOE and PNNL, Guide to Determining Climate Zone by County: Building America and IECC 2021 Updates (PNNL-33270), as of October 21, 2022. Homeowners do not search for a zone number. They search for the comfort problem that zone tends to produce, which is why the degree-day lines matter when this page has them.
The local reading for Seattle is ordinary, and it is specific. Heating is the larger degree-day number and the zone is marine, so drafts, cold rooms, and wet winters are the first story for Seattle. Check it against the grid. A message can be right for the climate and still be invisible three miles from the shop.
784,777 is the population figure for Seattle. The note on that line says: Estimate for July 1, 2025. The county line reads King County. Rankings on Google Maps are local to the searcher, so a strong pin near the shop can still leave the rest of a city this size uncovered.
Two next steps sit on this page: the free audit for a Seattle grid, and a strategy call if you want to discuss the market. Results from other cities, shown further down, are those markets only. They are not a promise for Seattle.

What this means for your marketing in Seattle
Seattle is in King County and falls in IECC climate zone 4C. In a typical year NOAA's 1991-2020 normals show 4,376 heating degree days and 265 cooling degree days, so heating is the larger load.
For a spray foam or insulation contractor, that tends to move what homeowners search for toward cold rooms, drafts, high heating bills and ice dams. Pages, ads and Google Business Profile services built around attic insulation, rim joists, basements and crawl spaces usually match that intent better than a generic insulation page.
The "C" in 4C marks a marine climate, with mild temperatures and plenty of moisture, so air sealing and moisture control belong in the message alongside insulation.
Seattle had an estimated 784,777 residents on July 1, 2025 (U.S. Census Bureau). Google Maps rankings change from one part of a market to the next, so being visible near your shop does not mean being visible across the whole service area. The free Market Visibility Audit shows your ranking at a grid of points around your business.
How the Google Maps grid works in a market like Seattle
Google Maps does not show one ranking for a whole city. The result changes block by block, depending on where the searcher is standing. Our audit searches from a grid of points around your business and records where you appear at each one. Green means you are in the top 3 at that spot. Red means customers there are not finding you. In Seattle, that grid is the check on whether you show up across the area you claim, not only beside the shop.

How working with us goes
Spray Foam Genius Marketing works with spray foam and insulation contractors. The steps are the same in Seattle as everywhere else. Plans are month to month, and you can end service with 30 days notice.
1. Audit
We look at where your company shows up on Google Maps in the cities you serve. The Market Visibility Audit is free. It shows the current grid. It is not a forecast, and it does not promise a ranking.
2. Plan
If the work is a fit, we write a plan for the website, the Google Business Profile, and the ads for the jobs you take. We do not sell shared leads. We do not promise that only one contractor in Seattle can hire us.
3. Launch
We set up the work in the plan. You buy and own the domain at a registrar you choose, such as Namecheap or GoDaddy. We do not hold the domain, and we do not transfer it. If we build a website, we can move that website to a host you choose after you have been with us at least 90 days and you end service with 30 days notice. Before 90 days the website stays with us.
4. Monthly review
Each month we review what is live: the map listing, the pages, and the ads. We do not bill per lead or per estimate.
