Home repair in Union, MO

Union is one of 4 places in Franklin County and the 2nd-largest of them — roughly 12% of the county's residents. Counties of this shape concentrate their trades in the bigger communities, so the practical question on a small job is not whether a pro will come but what the trip charge and minimum call-out add to the ticket.

The next place up from Union in Franklin County is Washington, with about 2,450 more residents, roughly 1.2× the size, which is a large enough step up that it carries trades Union may not, particularly at the specialised end.

Statewide, Union ranks 62nd by population among the 193 places Missouri records — larger than roughly 68% of them. That is the honest measure of how deep the local list of licensed trades runs, and of how far a specialist may have to travel for the less common work: sewer lines, panel replacement, structural repair.

Franklin County's population has held roughly flat since 2020, so the housing stock is established rather than new. That tilts the list toward maintenance and system replacement on homes that have been lived in a while — the water heater, the panel, the deck, the drywall that moved.

The median place in Franklin County holds about 10,277 residents; Union, at 13,000, is roughly 1.3× that. Being above the county median is the practical dividing line for whether a trade keeps someone stationed nearby or dispatches into town — and it is the single biggest factor in how a small job gets priced.

Missouri has 140 places our data classes the same way as Union — community scale — and they behave alike for repair pricing: the same mix of trades work them, the same travel economics apply, and the same jobs come around. That is the cohort the Union ranges below are drawn from, not a national average.

Franklin County accounts for 1.7% of Missouri's residents, 12th of the state's 115 counties by population. Outside the top few counties the everyday trades are still well covered, but the specialised end — sewer, structural, whole-system electrical — thins out, and that is the work most likely to involve a drive and a scheduling wait.

At about 13,000 residents, Union is unlikely to support a full bench of specialised trades of its own. Washington, the largest community in Franklin County, is where most of them are based, and it is the realistic dispatch point for anything beyond general repair. That is not a reason to look further afield — it is a reason to expect a trip charge on a small job and to bundle several small jobs into one visit.

The largest county bordering Franklin County is St. Louis County, with about 987,059 residents — a bigger market than this one, and the direction most of the specialist crews come from when the local list runs short.

The Franklin County communities closest to Union in size — Washington (~15,450), Pacific (~7,554), and Sullivan (~6,829) — are the fairest comparison, because a market of similar size draws a similar depth of crews and a similar travel component in the price. They also sit inside the same service radius, so the pro quoting Union on Monday is usually quoting them the same week.

The other job that comes up constantly here is deck build, which our 2026 model puts at $8,000–$12,000 for Union — a genuine local range, adjusted for Missouri labor and materials rather than averaged across the country.

Timing carries a real premium too. A drywall repair booked as planned work prices at $275–$400 in Union; the same job as same-day emergency service prices at $300–$450, about 15% higher. If the job can wait a week, waiting a week is the cheapest change you can make to it.

Every figure on this page is multiplied by a Missouri cost factor of 0.93 — labor and materials here run about 7% below the national baseline in our 2026 model. That adjustment is applied before you see a number, which is why these ranges differ from the national averages quoted on most cost-guide sites.
