Expanding into a new town is one of the most expensive bets a home services business makes. Before you put a truck on the road, you can answer most of the question — is this market worth it? — from data that's already public, if you know what to look at and how to weigh it.
Start with the housing stock
Plumbing demand follows the age and ownership of homes. Two numbers do most of the work:
- Owner-occupancy. Owners pay for repairs; renters call a landlord. A town above ~65% owner-occupancy has a much larger pool of people who can actually say yes to a repipe.
- Share of homes built before 2000. Original supply lines, fixtures, and water heaters start failing in volume around the 20–25 year mark. A high share of pre-2000 homes is a steady pipeline of replacement work.
Layer in income
Demand isn't enough on its own — homeowners have to be able to choose quality over the lowest bid. Median household income tells you whether a market supports premium jobs (tankless conversions, whole-home repipes, water treatment) or mostly patch repairs.
Then measure the competition
This is the step most owners skip, and it's the one that sinks expansions. Two signals matter:
- How many active contractors already serve the area.
- How entrenched the local pack is — the top three map results and their review counts. Competing against businesses with 500+ reviews is a different game than entering a market where the leader has 80.
A market can have great demand and be a bad bet if an incumbent already owns the map pack.
Put it together
The towns worth entering are the ones where strong housing-and-income demand meets a competitive field you can realistically break into. That intersection — not raw population — is where expansion dollars earn their return.
