Replacement demand, competitive density and housing stock for windows & doors in Iowa City, IA, 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 Iowa City 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.
Iowa City, IA has an unusually large pool of addressable homes, a climate that works the building envelope hard and real construction activity relative to its size. That works out to 35,440 addressable homes and an effective replacement cycle of about 21 years, or $22M of windows & doors a year.
Against that, the market has housing too new to need you yet and a crowded contractor market. 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.

The questions worth answering before committing capital to a market.
The Iowa City, IA metro generates roughly $22.36M of windows & doors demand a year, across about 2,244 jobs.

A single operator serving part of the metro can realistically reach $12.30M of it.
Iowa City scores 65.8 out of 100 for windows & doors, which ranks it 91 of 935 US metro areas. Iowa City, IA has an unusually large pool of addressable homes, a climate that works the building envelope hard and real construction activity relative to its size.
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 Iowa City, IA metro that is 307 specialty-trade contracting establishments (NAICS 238, covering roofing, siding, windows, gutters and the other exterior trades). That works out to 140.5 owner-occupied homes per contractor — the higher that number, the less crowded the market.
The average home in the Iowa City, IA metro is about 40.0 years old, and 42% of homes predate 1980. The median year of construction is 1988 — 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.
Public sources only: the US Census Bureau's American Community Survey and Building Permits Survey for housing and households, the Bureau of Labor Statistics' Quarterly Census of Employment and Wages for contractor counts, and NOAA Storm Events and Climate Normals for hail and weather exposure. Market sizing applies published replacement cycles and average ticket prices to that stock — it is a model, not a measurement, and every assumption is visible inside the interactive report.
Yes. This page and the full interactive Iowa City windows & doors market file are open access — no account, no card and no sales call. The methodology, including every weight and known limitation, is published in full.
Public data only. No proprietary panels, no estimates of estimates — every figure on this page traces to one of these.
Figures reflect the most recent published vintage of each source as of 2026-08-13. Market sizing is a model, not a measurement: it applies replacement cycles and average ticket prices to the housing stock. Service areas are whole metros, so a single branch serving a drive-time radius will address less than the totals shown.
