Spray Foam Genius Marketing helps spray foam and insulation contractors in Antioch, California 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 3B. The population line reads 118,958. They are a reading of those figures for a contractor, not a new study.
Antioch's median build year on this page is 1987. That year is later than the national median of 1981 printed in the same note. The note on that line says: National median: 1981 (survey estimate, with a margin of error). Pair it with the share of homes built before 1980 when that line exists, because a median hides the older tail.
Put together, the figures on this page suggest a practical order for Antioch marketing. Heating is the larger degree-day number, so cold-weather comfort is the first story for Antioch. Check it against the grid. A message can be right for the climate and still be invisible three miles from the shop.
The median value line reads $647,400 for Antioch. That is higher than the national figure of $360,600 in the same note. Treat it as a reference from the cited survey, not today's asking price. Market prices move after the survey date printed on the card.
Tenure is part of the marketing picture in Antioch: 64% of occupied homes are owner-occupied. 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. Landlords and builders remain a separate audience when the owner share is modest.
Antioch is in California, and the climate zone on this page is 3B. The moisture letter on this zone is dry (3B). The note reads: dry climate, zone 3 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.
118,958 is the population figure for Antioch. The note on that line says: Estimate for July 1, 2025. The county line reads Contra Costa County. Rankings on Google Maps are local to the searcher, so a strong pin near the shop can still leave the rest of a city this size uncovered.
Heating degree days (2,154) and cooling degree days (1,078) are both on this page. Both figures use base 65 F. The heating note says the reading was measured at CONCORD BUCHANAN FLD. Heating (2,154) is larger than cooling (1,078). 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.
Before-1980 construction is 38% in Antioch. That share is lower than the national figure of 48% in the same note. The note on that line says: National: 48% (survey estimate). Combine this with the median year rather than quoting only one of them in an ad.

What this means for your marketing in Antioch
64% of occupied homes in Antioch are owner-occupied (nationally: 65%), and the median home value is $647,400 (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.
Antioch is in Contra Costa County, which falls in IECC climate zone 3B. NOAA's 1991-2020 normals for CONCORD BUCHANAN FLD (about 14 miles away) show 2,154 heating degree days and 1,078 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 3B 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 Antioch at a build year of 1987 (nationally: 1981), and 38% 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.
Antioch had an estimated 118,958 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 Antioch
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 "Antioch" does not exist on Google Maps. The grid is how we record the change from point to point.

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.
