Spray Foam Genius Marketing helps spray foam and insulation contractors in San Antonio, Texas win more jobs from homeowners and builders searching in that market. Spray foam marketing in San Antonio, Texas should follow the climate and the housing stock you can actually cite. The climate zone on this page is 2A. The population line reads 1,548,422. The cards under the reading are the citations.
Cooling (3,148) is larger than heating (1,438). The heating degree-day value is 1,438 and the cooling value is 3,148. Both figures use base 65 F. The heating note says the reading was measured at SAN ANTONIO INTL AP. Pages and ads can lead with hot attics, summer bills, and rooms that will not cool. Put the larger load first on the Google Business Profile services and on the main service pages.
40% of homes in San Antonio 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.
The owner-occupied share on this page is 52% for San Antonio. 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.
San Antonio is listed at 1,548,422 residents. The note on that line says: Estimate for July 1, 2025. The county line reads Bexar County. Population is the width of the map, not a count of insulation buyers. A contractor who works one side of San Antonio should not treat the city total as the service area.
Put together, the figures on this page suggest a practical order for San Antonio marketing. Cooling is the larger degree-day number and the zone is humid, so attic heat, moisture, and air sealing belong at the front of a San Antonio site. 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 San Antonio only through the sourced median of $260,900. That is lower 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.
For a San Antonio contractor, the climate card is zone 2A. That is a humid classification. humid climate, zone 2 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.
The main heating fuel line for San Antonio reads electricity (70%). The note on that line says: Share of occupied homes (survey estimate). You can mention that fuel when you explain air sealing, because it is the bill owners already pay. Do not turn it into a promised savings figure.
Housing age in San Antonio is summarized as a median build year of 1986. 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 San Antonio
52% of occupied homes in San Antonio are owner-occupied (nationally: 65%), and the median home value is $260,900 (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.
San Antonio is in Bexar County, which falls in IECC climate zone 2A. NOAA's 1991-2020 normals for SAN ANTONIO INTL AP (about 6 miles away) show 1,438 heating degree days and 3,148 cooling degree days in a typical year, so cooling is the larger load. For a spray foam or insulation contractor, that tends to move what homeowners search for toward hot attics, high summer energy bills and rooms that will not cool. The "A" in 2A marks a humid climate, so moisture control and air sealing deserve space in your content.
The Census Bureau's 2024 American Community Survey puts the median home in San Antonio at a build year of 1986 (nationally: 1981), and 40% 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 San Antonio, 70% heat mainly with electricity and 28% 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.
San Antonio had an estimated 1,548,422 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 San Antonio
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 San Antonio service area you want. A good result next to the office can sit beside a miss a few miles away.

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.

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.
