Replacement demand, competitive density and housing stock for windows & doors in Louisville/Jefferson County, KY-IN, on the same basis as every other US metro. Every figure is computed from current Census, BLS and NOAA data and traceable to its source.
How much windows & doors work the Louisville/Jefferson County metro generates in a year, and what share of it a single branch or acquisition could realistically reach.
Computed from the component scores below — not written by hand, and not generated.
Louisville/Jefferson County, KY has an unusually large pool of addressable homes, storm exposure that pulls replacement forward and households that can fund a job of this size. That works out to 332,349 addressable homes and an effective replacement cycle of about 19 years, or $221M of windows & doors a year.
Against that, the market has a crowded contractor market and a mild climate that is easy on the envelope. Worth evaluating, though not obviously ahead of the alternatives — on these figures the market is raising its hand, not jumping out of its seat.
Seven components, each a percentile against all 935 US metros. The opportunity score is their weighted average, tilted toward what windows & doors specifically depends on.
The interactive market file adds the full component breakdown, the inputs behind every figure, side-by-side comparison with other metros, and a re-pricing against your own ticket and installed capacity.
Substitute your ticket and installed capacity and the file recalculates: what you could deliver here, how your pricing lands against local incomes, and what would have to be true for the case to hold. Open access, no account, and the result is a link you can put in a memo.

There is no metro-level count of windows & doors firms specifically — the Bureau of Labor Statistics publishes establishments at the trade-group level. For the Louisville/Jefferson County, KY-IN metro that is 2,478 specialty-trade contracting establishments (NAICS 238, covering roofing, siding, windows, gutters and the other exterior trades). That works out to 152.4 owner-occupied homes per contractor — the higher that number, the less crowded the market.
The average home in the Louisville/Jefferson County, KY-IN metro is about 46.1 years old, and 54% of homes predate 1980. The median year of construction is 1977 — that figure and the average age are two different statistics and will not line up exactly, because the average is a weighted mean across every construction-year band while the median is only the midpoint. Housing age is the single strongest driver of windows & doors replacement demand, because roofs, siding and windows are replaced on a cycle rather than bought on impulse.
