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.
