172 Plumbing contractors in San Antonio, TX — scored for agency prospecting
San Antonio has 172 active plumbing contractors profiled on LocalVein, with a median vulnerability score of 23 out of 100. About 15% operate without a website — the single strongest signal that a local service business is open to hiring a marketing agency.
The plumbing contractor market in San Antonio
Most homes in San Antonio came up in the 1984 era — the 30-to-50-year window where original spec components reach the end of their service life one system at a time. For plumbing contractors, that timing pattern is predictable enough to build a marketing calendar around: quarterly nurture flows beat emergency-only creative because the buyer is already running a mental tab of deferred work across plumbing, roof, electrical, HVAC. Agencies who win in this housing bracket treat each prospect as a long-cycle relationship and pitch package-and-plan rather than one-off fix.
With 172 registered plumbing contractors, San Antonio sits in the sweet spot for direct outreach: few enough that personal touches scale, many enough that the agency can build a real pipeline without burning the list in a month. Operators falling short of the 128-review median represent the natural first-call shortlist — they're established enough to have budget but behind enough on review velocity to feel the competitive pressure every week.
3% of plumbing contractors in San Antonio — 5 operators out of 147 — register a vulnerability score above 50 in LocalVein's model. 15% of the vertical is operating without a website, which is the cleanest yes/no filter available. That ratio tells agencies how large the addressable top-of-funnel really is before any personalization work begins, and it's the honest answer to the "is this market worth my outbound time?" question. When the vulnerable tier clears 20% of the list, the vertical pays back a focused campaign within the first month in nearly every market we track.
US benchmarks: median review count 32, share of operators with no website 22%. Markets where either number sits well above the benchmark concentrate more agency-ready prospects per outreach hour.

How we measure opportunity
Public-sector demographic data
Population, household income, home value, homeownership rate, median year structure built and self-employment density come from authoritative public demographic releases. Refreshed annually.
Live business records
Business names, addresses, ratings, review counts, websites, phone numbers and operating status come from live business records. Each profiled business is re-checked regularly so stale data drifts off the page.
Composite vulnerability score
We blend 19 signals (review velocity, star rating, website presence and freshness, ad pixels, hiring activity, competitor density and visual brand, plus eleven more) into a 0–100 score. Higher means more likely to engage with marketing services.

Phone line type detection (mobile / landline / VoIP) is a Core-tier and above feature, which agencies use to route SMS-eligible prospects to a separate outreach sequence than landline-only operators. Paid plans also surface a contact email for each business that publishes one on its own site — coverage is not universal. For San Antonio's plumbing contractors, line types populate on the first paid scan and persist indefinitely — phone line types almost never change.
