Spray Foam Genius Marketing helps spray foam and insulation contractors in Portland, Oregon win more jobs from homeowners and builders searching in that market. The paragraphs under this one use only the public figures already on the page, each of which keeps its source and date in the cards below. The climate zone on this page is 4C. The population line reads 635,109. They are a reading of those figures for a contractor, not a new study.
The local reading for Portland 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 Portland. Check it against the grid. A message can be right for the climate and still be invisible three miles from the shop.
Look at the zone before you write service pages for Portland. It is 4C. The moisture letter on this zone is marine (4C). Note: marine climate, zone 4 of 8. On the IECC scale used on our state pages, the number rises as the climate gets colder, from 1 (hot) to 8 (subarctic). The citation sits on the climate card below. Publisher: U.S. DOE and PNNL, Guide to Determining Climate Zone by County: Building America and IECC 2021 Updates (PNNL-33270).
Before-1980 construction is 62% in Portland. That share is higher than the national figure of 48% in the same note. The note on that line says: National: 48% (survey estimate). Combine this with the median year rather than quoting only one of them in an ad.
Tenure is part of the marketing picture in Portland: 51% of occupied homes are owner-occupied. That is lower than the national figure of 65% in the same note. The city figure is at least half, so owner-occupiers are the larger group in this survey line. They are usually the people who can commission insulation on a house they live in. Landlords and builders remain a separate audience when the owner share is modest.
The median value line reads $588,200 for Portland. That is higher than the national figure of $360,600 in the same note. Treat it as a reference from the cited survey, not today's asking price. Market prices move after the survey date printed on the card.
A typical year, as printed here, needs 4,104 heating degree days and 508 cooling degree days. Both figures use base 65 F. Heating (4,104) is larger than cooling (508). The heating note says the reading was measured at PORTLAND INTL AP. Pages and ads can lead with cold rooms, drafts, and heating bills. Do not copy a cold-climate service list onto a cooling-led city, or the reverse.
Nearby markets with their own pages, measured as a straight line from the Portland town center, are Vancouver, Washington (8 straight-line miles), Gresham (12 straight-line miles), and Hillsboro (15 straight-line miles). Forty miles is the cutoff this site uses for that list. A contractor's real drive area can be smaller or larger.
Heating fuel in Portland, as published here, is electricity (51%). The note on that line says: Share of occupied homes (survey estimate). Ads can name that fuel. They should not promise a bill outcome the source does not state.
Contractors sizing up Portland can start from 635,109 residents. The note on that line says: Estimate for July 1, 2025. Source on this page: U.S. Census Bureau, Vintage 2025 population estimates for cities and towns, as of July 1, 2025. The county line reads Multnomah County. The marketing question is which part of that population can hire the work, and the housing lines further down are the closer read when they are present.
Portland's median build year on this page is 1966. That year is earlier than the national median of 1981 printed in the same note. The note on that line says: National median: 1981 (survey estimate, with a margin of error). Pair it with the share of homes built before 1980 when that line exists, because a median hides the older tail.
Two next steps sit on this page: the free audit for a Portland 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 Portland.

What this means for your marketing in Portland
51% of occupied homes in Portland are owner-occupied (nationally: 65%), and the median home value is $588,200 (nationally: $360,600). Renters make up a large part of the city, and renters are less often the ones who commission insulation work, so the buyers you want are a smaller group of owners and landlords. It is worth checking in your Google Maps grid whether the strongest demand sits in the suburbs and towns around the city. Higher home values tend to go with owners who spend on comfort and performance, so quality, warranty and results messaging usually works better than leading with price.
Portland is in Multnomah County, which falls in IECC climate zone 4C. NOAA's 1991-2020 normals for PORTLAND INTL AP (about 4 miles away) show 4,104 heating degree days and 508 cooling degree days in a typical year, 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. 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.
The Census Bureau's 2024 American Community Survey puts the median home in Portland at a build year of 1966 (nationally: 1981), and 62% of its homes were built before 1980 (nationally: 48%). That is an older housing stock. Older homes are where attic insulation, air sealing and rim joist work tend to pay off for the owner, so retrofit and energy-bill messaging usually fits better here than a new-construction pitch.
Of occupied homes in Portland, 51% heat mainly with electricity and 45% with utility gas (ACS 2024). Where electricity is the main heating fuel, owners feel a leaky attic in the monthly bill, so energy-bill savings is a natural angle for pages and ads.
Portland had an estimated 635,109 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 Portland
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. Run it for the Portland service area you want. A good result next to the office can sit beside a miss a few miles away.

How working with us goes
Spray Foam Genius Marketing works with spray foam and insulation contractors. The steps are the same in Portland 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 Portland 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.
