A Houston plumber's website needs three things most generic plumbing templates skip: your Responsible Master Plumber's license number (Texas requires it in every advertisement, and your website counts), a plain answer about who pulls the permit inside and outside City of Houston limits, and a service area written the way people here actually search, by side of town and suburb. Add a tap-to-call number, pages for freeze and storm damage, and honest prices, and you've covered most of what makes a Houston caller pick up the phone.

The general basics (pages, photos, speed, schema) are in our plumbing website checklist. This post is about what changes when the site is for Houston, with a checklist at the end.

Why a Houston plumbing site can't be a generic template

Most plumber templates assume one water department, one permit office and mild weather. Houston has none of that. The city alone had an estimated 2.4 million people in mid-2025, according to the Census Bureau, and the metro sprawls across Harris, Fort Bend, Montgomery and the counties around them. Houston Water says it serves about 5.5 million people across more than 650 square miles. A homeowner in Kingwood and one in Missouri City both live "in Houston," but they're an hour or more apart in traffic and probably under different permit offices. A template that says "serving the greater Houston area" and nothing else doesn't tell either of them whether you'll come.

Put the RMP license number where people see it

Texas plumbing companies are licensed through the Texas State Board of Plumbing Examiners, and every company works under a Responsible Master Plumber (RMP). The board's rule on displaying the RMP's name and license number, 22 TAC §367.10, covers three places:

Where What the rule asks for
Advertisements, in any medium The license number of the RMP of record. Your website, Google ads, door hangers and social posts meant to win plumbing work all count.
Service vehicles The RMP's license number and the company name on both sides, on the body of the vehicle, in a contrasting color, at least 2 inches tall, with the number starting with "M", "MPL" or "RMP".
Proposals, invoices and contracts On the first page, in at least 12-point type: the RMP's full name and license number, the words "regulated by the Texas State Board of Plumbing Examiners", and the board's contact details and website. The rule counts estimates, receipts and other billing documents too.

The exceptions are narrow (things like promotional items, the permanent sign at your shop, and third-party listings you don't control). Your own website isn't one of them.

On the site, put the number next to the phone number in the header or directly under it, so it shows on every page. Then repeat it on the about and contact pages. Something like "Licensed by the TSBPE, RMP License M-XXXXX" does the job (use your real number, written exactly as it appears on the license). Keep it identical to the lettering on the truck.

The invoice part catches people out more than the website part. If your quotes and invoices come from a template you set up years ago, open one and check the first page against that table. If you're redoing it anyway, the invoice generator gives you a clean layout to start from. Just make sure those lines land on page one.

Not legal advice. Rules change, check with your licensing board.

Answer the permit question before they ask it

Houston homeowners have heard the stories about unpermitted work showing up when a house sells. "Do you pull the permit?" is a question you probably get weekly. Put the answer on the relevant service pages.

Inside City of Houston limits, the Houston Permitting Center's own pages are clear about a few things:

  • Water heaters need a plumbing permit and an inspection. The city's water heater page says the permit must be obtained by a master plumber registered with the City of Houston, and that an inspection is required.
  • Gas hookups need one too. Connecting a fuel gas appliance or device is a plumbing permit in the city, pulled by a registered master plumber. That covers a lot of storm season work (more on that below).
  • Master plumbers have to register their state license with the city before they can pull permits. The city lists the registration as free, valid for one year, with renewal required, and asks for the license number, proof of insurance, ID and a registration form.

On the code side, the city moved to the 2021 editions of the Uniform Plumbing Code and Uniform Mechanical Code, effective January 2, 2024, according to IAPMO's announcement of the adoption.

Outside the city it gets messier. Sugar Land, Pearland, Pasadena, Katy and the other incorporated cities run their own permitting. In unincorporated parts of the county, Texas law still says plumbing installed by a licensed plumber has to follow a code adopted by the state plumbing board and be inspected by a plumbing inspector (Texas Occupations Code §1301.255).

A homeowner doesn't need all that. They need one honest line on each service page that involves a permit, for example:

"We pull the permit and schedule the inspection, whether you're inside Houston city limits, in another city like Pearland or Sugar Land, or out in the county. The permit cost is listed on your quote."

If there's a city you don't pull permits in, it probably shouldn't be on your service area page.

Write your service area the way Houston searches

Nobody searches "plumber greater Houston area." They search "plumber Cypress," "water heater replacement Katy," "slab leak Meyerland," "emergency plumber Pearland." Google's help page on local ranking says local results are based mainly on relevance, distance and prominence, and distance counts for a lot in a metro this size. A plumber based in Spring won't show up much for someone in Clear Lake (and that's probably not a job you want at 5 pm on a weekday anyway).

Name the suburbs and parts of town you actually drive to, say where you stop, and give a rough response time if it varies. For example, three imaginary shops in different corners of the metro might write (use your own routes):

Based in Service area wording that helps callers
Northwest (Cypress) "Cypress, Jersey Village, Tomball, Katy north of I-10, and the Energy Corridor. We don't cover south of Westheimer or east of I-45."
Southwest (Missouri City) "Missouri City, Sugar Land, Stafford, Meyerland, Bellaire and Pearland. Same-day in Fort Bend most weekdays, next-day inside the Loop."
North (Kingwood) "Kingwood, Humble, Atascocita, Porter and New Caney. We do not travel south of Beltway 8."

Put this on a dedicated service area page and in a shorter form on the home page. Match it to the service area in your Google Business Profile. Our Google Business Profile guide for contractors covers the setup rules, including hiding your home address if customers don't come to you.

Neighborhood pages: only with something real to say

Skip the 40 near-identical suburb pages with the name swapped in. Google's spam policies treat that kind of page as a doorway. A page for Katy or the Heights earns its place when you can say real things about working there: the houses you see, jobs down the street, which permit office handles it, how fast you usually get there. If you can't fill 300 honest words, list the area on the service area page and move on.

Build pages for Houston's weather

A lot of Houston's worst plumbing weeks arrive with the weather. The pages need to be live before the weather turns, because nobody writes a good page in the middle of a freeze.

Freezes

Houston doesn't freeze often, which is exactly why it goes so badly when it does. The National Weather Service's February 2021 climate summary for the Houston area recorded a low of 13 degrees at Bush Intercontinental on February 16 of that year. Plenty of pipes that had never needed insulation found out the hard way.

A "frozen and burst pipe repair" page is worth having year round. It should say:

  • What to do right now (find and close the main shut-off, open a faucet to drain the line, turn off the water heater if the water supply is off)
  • Whether you take emergency calls during a freeze, and how you handle the backlog
  • That you do pipe insulation and hose bib covers in the fall (a nice early winter job)

Honestly, the insulation page might earn you more than the emergency page. People book it in November when they remember 2021.

Hurricanes and tropical storms

When Hurricane Beryl came through in July 2024, nearly 3 million electricity customers in Texas lost power, according to the Texas Tribune. Some went more than a week without it. After a week without power, a standby generator stops sounding like a luxury.

That matters to plumbers because, inside the city, connecting a gas appliance or device to the fuel gas line needs a plumbing permit pulled by a registered master plumber. If you run gas lines for generators, say so on a dedicated page. Name what you do (sizing and running the gas line, the permit, the inspection) and what you don't (the electrician usually handles the transfer switch).

Storm mode on your home page

When a freeze or storm is coming, add one line to the top of the home page, like "Taking emergency calls across Fort Bend County, expect delays of 24 to 48 hours." It tells a stressed caller you're open and is honest about the wait. Take it down afterward.

If you haven't written down how you charge for emergency and after-hours calls, do it while things are quiet. The plumbing emergency callout policy generator gives you clear wording for the site and for what you say on the phone.

Be careful with "Houston has hard water"

Plenty of Houston plumbing sites claim the city has very hard water, usually right above a softener offer. The city's own numbers are more mixed.

Houston Water's 2025 water quality report says about 90% of the main system's supply is surface water from the San Jacinto River (Lake Conroe and Lake Houston) and the Trinity River (Lake Livingston), with the rest from deep wells. Total hardness readings in the main system ranged from 43.5 to 229 parts per million across the year. That's a wide spread, and many suburban homes are on other water systems entirely, with their own reports.

So write about what you actually see. "We pull a lot of scaled-up water heaters in Cypress and Tomball" (if that's true for you) is more believable than a claim about the whole city, and you can back it with photos. If you sell softeners, offer to test the customer's water or point them to their own provider's report.

Say which languages you speak

The Census Bureau's 2020 to 2024 figures show 47.1% of Houston residents age 5 and up speak a language other than English at home. Spanish is by far the biggest share of that (the city planning department's older breakdown put it at more than a third of residents).

If someone on your team takes calls in Spanish, put "Hablamos español" next to the phone number. Same for any other language your crew speaks. Only if it's true for whoever answers the phone, though. A customer who calls because they saw it and gets an English-only voicemail won't call twice.

Put some numbers on the site

People comparing plumbers look for any hint of cost, and a site that gives one tends to get the form. You don't need to publish your price book. Three things usually cover it:

  • Your service call or diagnostic fee, and whether it's credited against the repair
  • "Starting from" prices on common jobs, with what pushes the price up
  • For water heaters, what changes the quote: gas or electric, tank or tankless, attic or garage, and the permit

For example: "A like-for-like 50-gallon gas water heater swap in a garage, with the permit, typically starts around $X. An attic install, a switch to tankless or a new gas line adds to that." (Put your real number in, and make sure it still covers a seized valve and a hot attic.)

The plumbing fixed-price job menu generator lays out a short menu of common jobs with the scope wording for each, so "drain clearing, $X" doesn't turn into an argument about which drain.

The pages a Houston plumbing site needs

The right-hand column is what changes for Houston.

Page Houston-specific detail to include
Home RMP license number by the phone, your side of town and suburbs, storm-mode line when needed
Water heaters Permit and inspection inside city limits, attic vs garage installs, your scale experience by area
Leak detection and slab leaks What you do and don't do (reroute vs repair under the slab), photos from real jobs
Drains and sewer Heavy-rain backups, camera inspections, cleanouts
Frozen and burst pipes What to do now, insulation and hose bib covers in the fall
Gas lines and generators Only if you run gas: permits, inspection, what the electrician does
Service area Suburbs and neighborhoods by name, where you stop, response time by area
About Owner and RMP name, license, insurance, city registration, crew and trucks
Contact or quote Short form, the languages you answer in, a reply time you can keep

The service page copy generator drafts each of these from a few details about the job and your area. Rewrite it the way you'd explain it to someone staring at a dead water heater in their garage. The FAQ generator gives you a starting set of questions for each page (cut it down, first drafts run long).

Reviews that mention where you worked

In a metro this spread out, a review that mentions the neighborhood shows the next Katy homeowner you've already worked in Katy. You can't tell customers what to write, but you can ask the same day, and a text that says "Thanks for having us out to your place in Bellaire today" makes it easy for them to mention Bellaire. The review request generator writes those texts for you, and our post on how to get more Google reviews covers what Google allows and what it doesn't.

Put a few recent ones on the site with first names and neighborhoods, and link to the full list on Google.

Quick answers

Does a Houston plumber need a license number on their website?

Yes. The Texas State Board of Plumbing Examiners' rule 22 TAC §367.10 requires the license number of the company's Responsible Master Plumber in all advertisements, and a company website is advertising.

Do you need a permit to replace a water heater in Houston?

Inside City of Houston limits, yes. The city says a water heater needs a plumbing permit pulled by a master plumber registered with the city, and an inspection is required.

What should a Houston plumbing website include?

A tap-to-call number, the RMP license number, a service area naming real suburbs and neighborhoods, pages for water heaters, leaks, drains and frozen pipes, a clear permit answer, starting prices, real photos and recent reviews.

Should I make a page for every Houston suburb?

Only for areas where you can write something true and specific, like the houses you see there, jobs you've done nearby and response times. Pages that just swap the suburb name can be treated by Google as doorway pages.

Does Houston have hard water?

It depends where. Houston Water's 2025 report shows total hardness in its main system ranging from 43.5 to 229 parts per million, and many suburbs are on other water systems. Talk about what you see on real jobs rather than one number for the whole metro.

Start with the header

Look at the top of your site on your phone today. The RMP license number and the tap-to-call number should sit together, with the parts of Houston you actually serve right below. Then write the frozen pipe page while it's still warm out and you have time to do it properly.
