Spray Foam Genius Marketing helps spray foam and insulation contractors in Renton, Washington win more jobs from homeowners and builders searching in that market. Use this as the Renton brief before you write a page or an ad. The climate zone on this page is 4C. The population line reads 104,975. Every comparison below is the city number set next to the national number from the same note, when the note has one.
On the population line, Renton shows 104,975. 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 King County. Use the city total as context. The audit grid, not the census count, is what shows where a company actually appears.
The owner-occupied share on this page is 56% for Renton. 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. A Google Business Profile that speaks only to homeowners still needs a service area that matches where those owners live, which may be outside the city limits.
Put together, the figures on this page suggest a practical order for Renton marketing. Heating is the larger degree-day number and the zone is marine, so drafts, cold rooms, and wet winters are the first story for Renton. Check it against the grid. A message can be right for the climate and still be invisible three miles from the shop.
43% of homes in Renton were built before 1980, according to the line on this page. That share is lower than the national figure of 48% in the same note. If that share is a large part of the city, retrofit pages deserve a real section, not a footnote under new construction.
Heating degree days (4,390) and cooling degree days (258) are both on this page. Both figures use base 65 F. The heating note says the reading was measured at RENTON MUNI AP. Heating (4,390) is larger than cooling (258). Pages and ads can lead with cold rooms, drafts, and heating bills. The station and the period belong to the source card, so quote them if you repeat the numbers in your own content.
Home values enter the conversation in Renton only through the sourced median of $703,500. 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). Use it to choose emphasis. Leave specific project prices off the marketing page unless they are your own quotes.
Renton is in Washington, and the climate zone on this page is 4C. The moisture letter on this zone is marine (4C). The note reads: 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. Zone is a reason to lead with the jobs people in this climate ask about, not a rank factor by itself.
Housing age in Renton is summarized as a median build year of 1985. That year is later than the national median of 1981 printed in the same note. Retrofit language fits an older median. Newer-construction language fits a later one. Use the median as a tilt, and keep both services if you actually sell both.

What this means for your marketing in Renton
56% of occupied homes in Renton are owner-occupied (nationally: 65%), and the median home value is $703,500 (nationally: $360,600). That is close to the national mix of owners and renters. 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.
Renton is in King County, which falls in IECC climate zone 4C. NOAA's 1991-2020 normals for RENTON MUNI AP (about 1 miles away) show 4,390 heating degree days and 258 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 Renton at a build year of 1985 (nationally: 1981), and 43% 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.
Renton had an estimated 104,975 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 Renton
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 Renton, 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 Renton 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 Renton 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.
