Spray Foam Genius Marketing helps spray foam and insulation contractors in Boulder, 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 105,689. They are a reading of those figures for a contractor, not a new study.
The owner-occupied share on this page is 42% for Boulder. That is lower than the national figure of 65% in the same note. The city figure is under half, so renters are a large part of occupied homes. Renters are less often the person who hires insulation, which makes owners and landlords the tighter audience. 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.
The nearest published city pages to Boulder are Longmont (14 straight-line miles), Westminster (17 straight-line miles), Arvada (18 straight-line miles), and Thornton (18 straight-line miles). Use them as internal links when those towns are really in your service area. The mileage note on each one is a straight line, not driving directions.
The local reading for Boulder is ordinary, and it is specific. Heating is the larger degree-day number, so cold-weather comfort is the first story for Boulder. With owner-occupancy at 42%, a Boulder campaign that speaks only to resident homeowners is aimed at the smaller tenure group. Check it against the grid. A message can be right for the climate and still be invisible three miles from the shop.
On the population line, Boulder shows 105,689. 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 Boulder County. Use the city total as context. The audit grid, not the census count, is what shows where a company actually appears.
Read the two degree-day lines together. Heating is 10,824. Cooling is 0. Both figures use base 65 F. Heating (10,824) is larger than cooling (0). The heating note says the reading was measured at BOULDER 14 W. Pages and ads can lead with cold rooms, drafts, and heating bills. This comparison uses only those two figures.
Housing age in Boulder is summarized as a median build year of 1977. That year is earlier 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.
Boulder 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.
Home values enter the conversation in Boulder only through the sourced median of $1,115,300. 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.
Heating fuel in Boulder, as published here, is utility gas (64%). 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.
55% of homes in Boulder were built before 1980, according to the line on this page. That share is higher 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.
Use the audit to see the Boulder grid, or book a strategy call to go through it with us. We work only with spray foam and insulation contractors. Plans are month to month with 30 days notice. You buy and own your domain at a registrar you choose. We do not hold it, and we do not transfer a domain.

What this means for your marketing in Boulder
42% of occupied homes in Boulder are owner-occupied (nationally: 65%), and the median home value is $1,115,300 (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.
Boulder is in Boulder County, which falls in IECC climate zone 5B. NOAA's 1991-2020 normals for BOULDER 14 W (about 15 miles away) show 10,824 heating degree days and 0 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 Boulder at a build year of 1977 (nationally: 1981), and 55% 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.
Of occupied homes in Boulder, 64% heat mainly with utility gas and 35% with electricity (ACS 2024). With utility gas heating most homes, owners compare their winter gas bills, so comfort and heating-bill savings are the familiar angle.
Boulder had an estimated 105,689 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 Boulder
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 Colorado contractor working Boulder, green and red are positions at those points. They are not a citywide trophy.

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