Spray Foam Genius Marketing helps spray foam and insulation contractors in Westminster, Colorado 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 5B. The population line reads 116,182. They are a reading of those figures for a contractor, not a new study.
The local reading for Westminster is ordinary, and it is specific. Heating is the larger degree-day number, so cold-weather comfort is the first story for Westminster. Check it against the grid. A message can be right for the climate and still be invisible three miles from the shop.
Home values enter the conversation in Westminster only through the sourced median of $580,600. 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.
A typical year, as printed here, needs 5,765 heating degree days and 813 cooling degree days. Both figures use base 65 F. Heating (5,765) is larger than cooling (813). The heating note says the reading was measured at DENVER-STAPLETON. 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.
The owner-occupied share on this page is 60% for Westminster. 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.
33% of homes in Westminster 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.
Westminster is in Colorado, and the climate zone on this page is 5B. The moisture letter on this zone is dry (5B). The note reads: dry climate, zone 5 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 Westminster is summarized as a median build year of 1988. 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.
Westminster is listed at 116,182 residents. The note on that line says: Estimate for July 1, 2025. The county line reads Jefferson County. Population is the width of the map, not a count of insulation buyers. A contractor who works one side of Westminster should not treat the city total as the service area.
Arvada (3 straight-line miles), Thornton (4 straight-line miles), Denver (7 straight-line miles), and Lakewood (9 straight-line miles) sit near Westminster on the straight-line list (OpenStreetMap town centers, 40-mile cutoff, nearest mile). Being visible in Westminster does not mean the Google Maps grid looks the same in those towns. Run the grid for the area you want to cover.
Two next steps sit on this page: the free audit for a Westminster 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 Westminster.

What this means for your marketing in Westminster
60% of occupied homes in Westminster are owner-occupied (nationally: 65%), and the median home value is $580,600 (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.
Westminster is in Jefferson County, which falls in IECC climate zone 5B. NOAA's 1991-2020 normals for DENVER-STAPLETON (about 13 miles away) show 5,765 heating degree days and 813 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 "B" in 5B marks a dry climate, so the story is mostly temperature and energy bills rather than humidity.
The Census Bureau's 2024 American Community Survey puts the median home in Westminster at a build year of 1988 (nationally: 1981), and 33% of its homes were built before 1980 (nationally: 48%). That is a younger housing stock than most of the country. A larger share of the work comes from new construction and recent builds, so builder and developer outreach deserves a place next to homeowner retrofit pages.
Westminster had an estimated 116,182 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 Westminster
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. A single rank for "Westminster" does not exist on Google Maps. The grid is how we record the change from point to point.

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