Spray Foam Genius Marketing helps spray foam and insulation contractors in Louisville, Kentucky 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 4A. The population line reads 631,818. They are a reading of those figures for a contractor, not a new study.
Before-1980 construction is 61% in Louisville. That share is higher than the national figure of 50% in the same note. The note on that line says: National: 50% (5-year survey estimate, with a wider margin of error for smaller cities). Combine this with the median year rather than quoting only one of them in an ad.
The climate figure for Louisville is zone 4A. Quoted from the note: humid climate, zone 4 of 8. The moisture letter on this zone is humid (4A). 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. A page written for a different zone will talk about the wrong season. Match the services on the website and the Google Business Profile to this zone.
Heating fuel in Louisville, as published here, is utility gas (59%). The note on that line says: Share of occupied homes (5-year survey estimate, with a wider margin of error for smaller cities). Ads can name that fuel. They should not promise a bill outcome the source does not state.
Louisville's median build year on this page is 1971. That year is earlier than the national median of 1980 printed in the same note. The note on that line says: National median: 1980 (5-year survey estimate, with a wider margin of error for smaller cities). Pair it with the share of homes built before 1980 when that line exists, because a median hides the older tail.
The local reading for Louisville is ordinary, and it is specific. Heating is the larger degree-day number, so cold-weather comfort is the first story for Louisville. 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 $233,900 for Louisville. That is lower than the national figure of $332,700 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.
Read the two degree-day lines together. Heating is 4,151. Cooling is 1,543. Both figures use base 65 F. Heating (4,151) is larger than cooling (1,543). The heating note says the reading was measured at LOUISVILLE BOWMAN FLD. Pages and ads can lead with cold rooms, drafts, and heating bills. This comparison uses only those two figures.
Tenure is part of the marketing picture in Louisville: 61% 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.
On the population line, Louisville shows 631,818. 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 Jefferson County. Use the city total as context. The audit grid, not the census count, is what shows where a company actually appears.

What this means for your marketing in Louisville
The Census Bureau's 2020-2024 American Community Survey (5-year estimates) puts the median home in Louisville at a build year of 1971 (nationally: 1980), and 61% 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.
Louisville is in Jefferson County, which falls in IECC climate zone 4A. NOAA's 1991-2020 normals for LOUISVILLE BOWMAN FLD (about 4 miles away) show 4,151 heating degree days and 1,543 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 "A" in 4A marks a humid climate, so moisture control and air sealing deserve space in your content.
61% of occupied homes in Louisville are owner-occupied (nationally: 65%), and the median home value is $233,900 (nationally: $332,700). That is close to the national mix of owners and renters.
Of occupied homes in Louisville, 59% heat mainly with utility gas and 39% with electricity (ACS 2020-2024, 5-year). With utility gas heating most homes, owners compare their winter gas bills, so comfort and heating-bill savings are the familiar angle.
Louisville had an estimated 631,818 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 Louisville
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 Kentucky contractor working Louisville, green and red are positions at those points. They are not a citywide trophy.

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