Spray Foam Genius Marketing helps spray foam and insulation contractors in Chicago, Illinois win more jobs from homeowners and builders searching in that market. Contractors in Chicago do not need a generic insulation page with the city name swapped in. The climate zone on this page is 5A. The population line reads 2,731,585. The differences that matter here are the ones these sources already measured.
Heating degree days (5,974) and cooling degree days (1,003) are both on this page. Both figures use base 65 F. The heating note says the reading was measured at CHICAGO OHARE INTL AP, IL. Heating (5,974) is larger than cooling (1,003). 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.
2,731,585 is the population figure for Chicago. The note on that line says: Estimate for July 1, 2025. The county line reads Cook 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.
Zone 5A is the climate designation published for Chicago. The moisture letter on this zone is humid (5A). The accompanying note is "humid climate, zone 5 of 8". 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. 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.
Read as a set, the sourced lines suggest what a Chicago contractor should say first. Heating is the larger degree-day number, so cold-weather comfort is the first story for Chicago. Check it against the grid. A message can be right for the climate and still be invisible three miles from the shop.
Start with the audit if you want to see where a Chicago listing stands at more than one point on the map. Book a strategy call when you want a person to go through the options. We do not offer pay-per-lead pricing, and we do not limit the work to one contractor per city.

What this means for your marketing in Chicago
Chicago is in Cook County and falls in IECC climate zone 5A. In a typical year NOAA's 1991-2020 normals show 5,974 heating degree days and 1,003 cooling degree days, 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. Pages, ads and Google Business Profile services built around attic insulation, rim joists, basements and crawl spaces usually match that intent better than a generic insulation page.
The "A" in 5A marks a humid climate. Moisture control comes up more often there, so content that explains air sealing and vapor control helps a buyer trust a contractor before they call.
Chicago had an estimated 2,731,585 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 Chicago
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 Chicago service area you want. A good result next to the office can sit beside a miss a few miles away.

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