Spray Foam Genius Marketing helps spray foam and insulation contractors in Carolina, Puerto Rico 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 1A. The population line reads 152,204. They are a reading of those figures for a contractor, not a new study.
The owner-occupied share on this page is 68% for Carolina. That is higher 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.
Housing age in Carolina is summarized as a median build year of 1970. That year is earlier than the national median of 1980 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.
A typical year, as printed here, needs 0 heating degree days and 5,433 cooling degree days. Both figures use base 65 F. Cooling (5,433) is larger than heating (0). The heating note says the reading was measured at WFO SAN JUAN. Pages and ads can lead with hot attics, summer bills, and rooms that will not cool. Do not copy a cold-climate service list onto a cooling-led city, or the reverse.
Home values enter the conversation in Carolina only through the sourced median of $157,600. That is lower than the national figure of $332,700 in the same note. The note on that line says: Owner-occupied homes. National: $332,700 (5-year survey estimate, with a wider margin of error for smaller cities). Use it to choose emphasis. Leave specific project prices off the marketing page unless they are your own quotes.
Zone 1A is the climate designation published for Carolina. The moisture letter on this zone is humid (1A). The accompanying note is "humid climate, zone 1 of 8". Source on this page: International Code Council, International Energy Conservation Code (IECC 2018), Table C301.1 (Puerto Rico is listed as zone 1A for the whole territory), as of 2018. Homeowners do not search for a zone number. They search for the comfort problem that zone tends to produce, which is why the degree-day lines matter when this page has them.
Contractors sizing up Carolina can start from 152,204 residents. The note on that line says: 5-year survey estimate, with a wider margin of error for smaller cities. Source on this page: U.S. Census Bureau, 2020-2024 American Community Survey 5-year estimates, table B01003, as of 2020-2024. The county line reads Carolina Municipio. The marketing question is which part of that population can hire the work, and the housing lines further down are the closer read when they are present.
70% of homes in Carolina were built before 1980, according to the line on this page. That share is higher than the national figure of 50% 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 local reading for Carolina is ordinary, and it is specific. 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 Carolina site. Check it against the grid. A message can be right for the climate and still be invisible three miles from the shop.

What this means for your marketing in Carolina
The Census Bureau's 2020-2024 American Community Survey (5-year estimates) puts the median home in Carolina at a build year of 1970 (nationally: 1980), and 70% of its homes were built before 1980 (nationally: 50%). That is an older housing stock. Older homes are where attic insulation, air sealing and rim joist work tend to pay off for the owner, so retrofit and energy-bill messaging usually fits better here than a new-construction pitch.
Carolina is in Carolina Municipio, which falls in IECC climate zone 1A. NOAA's 1991-2020 normals for WFO SAN JUAN (about 3 miles away) show 0 heating degree days and 5,433 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 1A marks a humid climate, so moisture control and air sealing deserve space in your content.
68% of occupied homes in Carolina are owner-occupied (nationally: 65%), and the median home value is $157,600 (nationally: $332,700). That is close to the national mix of owners and renters. Lower home values tend to go with more price-aware buyers, so clear pricing, financing options and any rebates you can verify help.
Carolina had an estimated 152,204 residents in the 2020-2024 American Community Survey (5-year estimates). 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 Carolina
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. In Carolina, that grid is the check on whether you show up across the area you claim, not only beside the shop.

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