Mindflow works from one place: Atlanta, Georgia. There is no Mindflow office in Houston and no address for us here, because none exists. This is a market we serve rather than a market we sit in. Our one real location is here.
- Advertising plumbing in Texas requires a responsible master plumber, per section 1301.351(a-2)
- Unincorporated Harris County issues no plumbing permits at all
- City median build year is 1981 against the metro's 1992
- Floodplain development permits come from a different office than trade permits
Advertising plumbing is itself a regulated act
The Texas Plumbing License Law, Occupations Code Chapter 1301, contains a clause that most marketing copy is written in ignorance of. Section 1301.351(a-2) reads: “A person that advertises or otherwise offers to perform or provide plumbing must secure the services of a responsible master plumber.”
Read that as written. The obligation attaches to the advertisement, not to the job. A company running ads, a website or a Google Business Profile offering plumbing in Texas needs a responsible master plumber secured before any work is sold, and a lead-generation site that offers plumbing without one is exposed on the same clause.
Section 1301.351(a) separately requires anyone engaging in plumbing to hold the proper licence and work under supervision. Licence types run Tradesman Plumber-Limited, Journeyman, Master, and Plumbing Inspector, with endorsements. The board is subject to the Texas Sunset Act and the chapter expires 1 September 2033 absent renewal.
The permit requirement stops at the city limit
Inside Houston, Public Works Building Code Enforcement issues plumbing permits and contractors must register their state licence with the City before pulling one.
Outside it, the Harris County Office of the County Engineer publishes 56 permit types for the unincorporated area, and none of them is a plumbing permit. The same repipe that needs a permit and an inspection in Houston may need no county permit at all in Spring, Cypress, Atascocita or Channelview.
Houston has no zoning map to make that boundary legible, so a company whose service area straddles it needs a jurisdiction check before the quote rather than after. That is a real operational difference and it is worth saying plainly to customers, because it changes what they are buying.
An old city inside a much newer metro
The city of Houston records a median year of construction of 1981 against the metro's 1992. A 1981 median puts a large share of city housing into cast iron drain lines and galvanised supply, where a metro built a decade later mostly is not.
The city is also majority-renter at 42.0% owner-occupancy against 61.2% across the metro, and 43.0% single-family detached against 62.6%. Emergency and repair work concentrates in the city; replacement and repipe work concentrates outside it.
The floodplain rules matter here too. Post-Harvey amendments effective 1 September 2018 require new and substantially improved structures in the 100-year and 500-year floodplain to be elevated to the 500-year flood elevation plus two feet, and floodplain development permits come from a different office than the trade permit counter.
This page covers plumbing specifically. The wider market picture for this city, covering climate, housing stock, storm exposure and which body issues the permit, sits on the Houston market page, and the state rules are on the Texas page.

What is missing is deliberate: no cost per lead, no conversion rate, no local benchmark. Those move by market and season, and any number published here would be wrong by the time you read it. Your own account holds the real one, and our calculators do the arithmetic once you have it.

Fair questions about plumbing in Houston
Does running plumbing ads in Texas require a licence?
The statute requires a responsible master plumber for anyone who advertises or otherwise offers to perform plumbing, under Occupations Code section 1301.351(a-2). The obligation attaches to the advertising, so it applies before any work is sold.
Do I need a permit for plumbing work outside Houston?
Often not. The Harris County Office of the County Engineer's published permit list for the unincorporated area contains no plumbing permit. Check the jurisdiction of the specific address before quoting, since Houston has no zoning map to make the boundary obvious.
Where is repipe demand concentrated?
In the older city core rather than the metro. The city median build year is 1981 against 1992 metro-wide, which puts more city housing into cast iron and galvanised systems.
