Spray Foam Genius Marketing helps spray foam and insulation contractors in St. Catharines, Ontario 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 5. The population line reads 136,803. They are a reading of those figures for a contractor, not a new study.
Put together, the figures on this page suggest a practical order for St. Catharines marketing. Heating is the larger degree-day number, so cold-weather comfort is the first story for St. Catharines. Check it against the grid. A message can be right for the climate and still be invisible three miles from the shop.
The owner-occupied share on this page is 64% for St. Catharines. That is lower than the national figure of 66% 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.
56% of homes in St. Catharines are single-detached, on the figure published here. That is higher than the national figure of 53% in the same note. That split should change which customer you describe: the house owner, the builder, or the property manager.
Home values enter the conversation in St. Catharines only through the sourced median of $548,000. That is higher than the national figure of $472,000 in the same note. The note states the values are in Canadian dollars. The note on that line says: Owner-estimated, in Canadian dollars. National: $472,000 (values as of the May 2021 Census). Use it to choose emphasis. Leave specific project prices off the marketing page unless they are your own quotes.
For a St. Catharines contractor, the climate card is zone 5. Zone 5 of the National Energy Code of Canada for Buildings (zones 4 to 8, from mildest to coldest). Source on this page: National Energy Code of Canada for Buildings (2020) building climate zones by heating degree days, as published by ClimateData.ca, as of 2020. Keep that zone in mind when you name attic, wall, or crawl-space work on the site.
Heating degree days (3,561) and cooling degree days (354) are both on this page. Both figures use base 18 C. The heating note says the reading was measured at VINELAND RITTENHOUSE (about 14 km away). Heating (3,561) is larger than cooling (354). 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.
136,803 is the population figure for St. Catharines. The note on that line says: 2021 Census count, up 2.8% from 2016. The province line reads Ontario. 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.
Use the audit to see the St. Catharines grid, or book a strategy call to go through it with us. We work only with spray foam and insulation contractors. Plans are month to month with 30 days notice.

What this means for your marketing in St. Catharines
The 2021 Census counted 136,803 people in St. Catharines, up 2.8% from 2016 (Canada: up 5.2%). That is close to the national pace, so a mix of retrofit and new-construction pages fits.
St. Catharines is in building climate zone 5 of the National Energy Code of Canada for Buildings (zones run from 4, the mildest, to 8). Environment Canada's 1981-2010 normals for VINELAND RITTENHOUSE (about 14 km away) show 3,561 heating degree days and 354 cooling degree days in a typical year, so heating is by far the larger load. For a spray foam or insulation contractor, a heating-dominated climate tends to move what homeowners search for toward cold rooms, drafts, high heating bills and ice dams, with hot-attic and summer comfort searches as a smaller second theme.
64% of households in St. Catharines own their home (Canada: 66%), and the median owner-estimated home value was $548,000 in the 2021 Census (Canada: $472,000). Market prices have moved since 2021, so treat the value as a 2021 reference point. That is close to the national mix of owners and renters.
56% of occupied homes in St. Catharines are single-detached houses (Canada: 53%), according to the 2021 Census. That is close to the national mix, so a blend of homeowner retrofit pages and builder or multi-unit pages fits the market.
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 of St. Catharines. 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 St. Catharines
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. For a Ontario contractor working St. Catharines, green and red are positions at those points. They are not a citywide trophy.

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 St. Catharines 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.
