Spray Foam Genius Marketing helps spray foam and insulation contractors in Gresham, Oregon win more jobs from homeowners and builders searching in that market. Contractors in Gresham do not need a generic insulation page with the city name swapped in. The climate zone on this page is 4C. The population line reads 111,513. The differences that matter here are the ones these sources already measured.
The pre-1980 housing line for Gresham reads 46%. That share is lower than the national figure of 48% in the same note. Source on this page: U.S. Census Bureau, 2024 American Community Survey 1-year estimates, table B25034, as of 2024. Write about air sealing and attic work for those houses only in the terms you can actually explain. The statistic does not say which neighborhoods hold the older homes.
Gresham is listed at 111,513 residents. The note on that line says: Estimate for July 1, 2025. The county line reads Multnomah County. Population is the width of the map, not a count of insulation buyers. A contractor who works one side of Gresham should not treat the city total as the service area.
For a Gresham contractor, the climate card is zone 4C. That is a marine classification. 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). 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. Keep that zone in mind when you name attic, wall, or crawl-space work on the site.
Read as a set, the sourced lines suggest what a Gresham contractor should say first. Heating is the larger degree-day number and the zone is marine, so drafts, cold rooms, and wet winters are the first story for Gresham. Check it against the grid. A message can be right for the climate and still be invisible three miles from the shop.
Median home value in Gresham is $459,000. That is higher than the national figure of $360,600 in the same note. The note on that line says: Owner-occupied homes. National: $360,600 (survey estimate). A higher or lower value is not a price you should promise for a job. It is a clue about which message to lead with, comfort and performance or straightforward savings, and it stays tied to the survey year.
When the site talks about old houses versus new ones in Gresham, the sourced median is 1982. That year is later than the national median of 1981 printed in the same note. Source on this page: U.S. Census Bureau, 2024 American Community Survey 1-year estimates, table B25035, as of 2024. Do not turn the median into a claim that most homes were built in that exact year. A median is the midpoint of the survey, and the note says it is a survey estimate when that is what the source published.
Gresham shows 55% owner-occupied. That is lower than the national figure of 65% in the same note. Source on this page: U.S. Census Bureau, 2024 American Community Survey 1-year estimates, table B25003, as of 2024. 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. Do not read the percentage as a market-share goal. It is a housing tenure figure from the source named on the card.
Heating (4,155) is larger than cooling (427). The heating degree-day value is 4,155 and the cooling value is 427. Both figures use base 65 F. The heating note says the reading was measured at PORTLAND TROUTDALE AP. Pages and ads can lead with cold rooms, drafts, and heating bills. Put the larger load first on the Google Business Profile services and on the main service pages.

What this means for your marketing in Gresham
55% of occupied homes in Gresham are owner-occupied (nationally: 65%), and the median home value is $459,000 (nationally: $360,600). That is close to the national mix of owners and renters.
Gresham is in Multnomah County, which falls in IECC climate zone 4C. NOAA's 1991-2020 normals for PORTLAND TROUTDALE AP (about 4 miles away) show 4,155 heating degree days and 427 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 Gresham at a build year of 1982 (nationally: 1981), and 46% of its homes were built before 1980 (nationally: 48%). That is close to the national picture, so a mix of retrofit pages for older homes and pages for newer construction fits the market.
Gresham had an estimated 111,513 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 Gresham
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. For a Oregon contractor working Gresham, green and red are positions at those points. They are not a citywide trophy.

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 Gresham 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.
