We Bring the Supply House to the Point

Living in San Leon means enjoying the bay breeze and direct access to some of the best fishing on the Texas coast. But it also usually means waiting days for service or paying high “trip charges” from Houston plumbers who treat your address like it’s on the moon.

At Blackmon Plumbing, we believe you shouldn’t be penalized for living on the coast.

Our fleet is constantly circulating through Dickinson, Bacliff, and San Leon. We don’t dispatch a technician from Conroe or The Woodlands; we dispatch the nearest Mobile Warehouse that is already working in Galveston County—often just minutes away in Texas City or La Marque.

Whether you are at a fish camp near Topwater Grill or a stilt home on Broadway, our box vans arrive fully stocked with:

  • Corrosion-Resistant Parts: Stainless steel clamps, brass fittings, and PEX pipe that won’t rust in the salty air. We don’t stock cheap galvanized components that will fail in six months.
  • Stilt Home Gear: Heavy-duty Armaflex insulation, stainless steel strapping, and heat tape to secure exposed pipes under elevated homes and protect them from freezing.
  • Tankless Inventory: Replacement parts and full units for Rinnai and Navien tankless water heaters—perfect for saving space in coastal cottages and fishing camps.
  • Generator Equipment: Gas line components (natural and propane) sized for standby generators that keep your AC and refrigeration running during storm outages.

This isn’t a plumber showing up with a toolbox and a promise to “go check the supply house.” This is a 2,000-part rolling warehouse dispatched to the end of FM 646.

Plumbing That Survives the Salt Air

San Leon is surrounded by water on three sides—Galveston Bay to the south, Dollar Bay to the east, and Dickinson Bayou to the north. The salt spray, constant humidity, and occasional high tides from tropical systems create a brutal environment for standard plumbing materials designed for inland homes.

If you’ve lived here more than a year, you already know: what lasts 15 years in Katy might only last 5 years at the Point.

Serving the Entire Peninsula

We know the territory—from the older bay houses near the marinas to the new elevated construction going up after Harvey. You will frequently see Blackmon Plumbing trucks servicing homes in:

  • San Leon (Proper)
  • Bacliff (neighboring community to the north)
  • Eagle Point
  • Sunnyview
  • Bayview
  • April Fool Point
  • Pier 6

From the bars and grills on 18th Street to the quiet fishing spots near April Fool Point, we are the local Master Plumbers who show up ready to work.

Local FAQ

Q: Do you charge extra for coming all the way to San Leon?

A: No. We believe in upfront, flat-rate pricing. You pay for the repair, not for the technician’s drive time down FM 646. Our fleet is constantly circulating through Galveston County, so we’re dispatching from nearby areas like Dickinson, Texas City, or La Marque—not from our Baytown headquarters.

Q: My pipes freeze every winter under my house. Can you fix that permanently?

A: Yes. We can replace broken sections with PEX piping (which expands better than copper when ice forms) and wrap all exposed lines in industrial-grade Armaflex insulation. We also install self-regulating heat tape that only activates when temperatures approach freezing. This three-layer approach has protected stilt homes through multiple freezes.

Q: Why does my hot water smell like rotten eggs?

A: This is often a reaction between the magnesium anode rod in your water heater tank and the local water, which can have higher sulfate levels near the bay. We can replace the rod with an aluminum/zinc anode that doesn’t react the same way, or upgrade you to a Tankless unit that doesn’t use anode rods at all—eliminating the smell permanently.

Q: How long do water heaters last in San Leon?

A: Standard steel tank water heaters typically last 5-8 years in San Leon due to salt air corrosion—compared to 10-15 years inland. Tankless water heaters with stainless steel heat exchangers last significantly longer because they don’t have a steel tank that can rust. If you’re tired of replacing tanks every few years, tankless is the smart investment for coastal homes.

Q: Can you work on elevated homes and fish camps?

A: Absolutely. Elevated homes and stilt construction are standard in San Leon, and we have specific experience securing and insulating exposed plumbing under these structures. We understand the challenges of working with pilings, securing lines against high winds, and protecting pipes from both freezing and salt damage.

Q: Will you pull permits for generator gas lines?

A: Yes. We pull permits for all gas line work to ensure your installation is legal and meets code. This protects you during insurance inspections and home sales. Some contractors skip permits to save money—we don’t cut corners on safety or compliance.

Q: My sewer backs up after heavy rain. Is that normal?

A: Not necessarily. Heavy rain can overload the public sewer system (if you’re on municipal sewer), but it can also indicate that your sewer line has joints that have separated, allowing rainwater to infiltrate. We perform a camera inspection to determine whether the problem is your line or the municipal system. If it’s your line, we fix it. If it’s the city’s problem, we help you document it.
