Full-service residential and commercial plumbing and mechanical, led by a Responsible Master Plumber with a master medical-gas endorsement. The same crews trusted on hospitals and high-rises will fix the faucet in your kitchen. No job too small, none too big.
What we do
Whatever’s on your list, it’s on ours. We handle the everyday repairs that keep a home or business running, and the bigger installs and mechanical work that keep it built right.
Leaks, clogs, running toilets, low pressure, fixture swaps, the calls that can’t wait.
Tank and tankless install, repair, and replacement. Gas, electric, and hybrid systems.
Drain cleaning, camera inspection, hydro-jetting, and sewer line repair or replacement.
Whole-home repipes and ground-up rough-in for builders, GCs, and remodels.
Complete residential new-home plumbing, from slab and underground rough-in through top-out and trim, built clean and ready for inspection.
Process piping, mechanical-room work, and HVAC piping for offices, retail, and light industrial.
Certified medical gas install, repair, and certification for hospitals, clinics, and labs, held under a master med-gas endorsement.

Combustion flue and appliance venting installed and corrected for safe, code-compliant exhaust.
Drain, waste, and vent systems designed and installed to drain right and breathe right.

Need it fast for a listing or a closing? We turn around clear, dated plumbing inspection reports on tight timelines, so nothing stalls at the inspection line.
Licensed & certified
These aren’t decoration. They’re the licenses and certifications that qualify us for medical, institutional, and high-rise work, and they back every residential job too.
Licensed RMP, the highest plumbing license in Texas, legally responsible for the work and the crew behind it.
Certified to install and certify medical gas and vacuum systems for hospitals, surgical centers, and labs.
Licensed Backflow Prevention Assembly Tester, qualified to test and certify backflow assemblies to code.
30-hour OSHA construction safety training, ready for the job-site and safety standards large GCs require.
Our track record
Our history is built on demanding commercial and institutional work, the kind that gets inspected hard and can’t come back. That same standard goes into every home we touch.
Project leadership
Harrington brings superintendent-level experience to the table. We have run piping, plumbing, and full MEP scopes on large commercial projects for general contractors, so we speak the language of schedules, submittals, and specs, and we can draw it in CAD before it ever reaches the field.
For GCs and owners, that means a partner who keeps the trades coordinated, the quality high, and the schedule honest.
Commercial caliber, residential care
We don’t run two different companies. The license, the crew, and the quality control behind a high-rise or a hospital go into your kitchen remodel too. The scale changes. The standard doesn’t.
If it’s good enough for a hospital, it’s good enough for your house.
Why Harrington
Fast scheduling and real people on the line, including after hours for emergencies.
You approve the price before we start. No surprises stacked on at the end.
Fully licensed and insured, and we stand behind every job we complete.
The small repair gets the same care as the big build. We want the relationship, not just the ticket.
Who you’re hiring
Behind Harrington Plumbing & Mechanical is Dustin Harrington, a Responsible Master Plumber with a master medical-gas endorsement. He has run piping, plumbing, and full MEP scopes on hospitals, schools, and high-rises.
He built this company on a simple idea: bring that same standard to every job, whether it is a hospital wing or a leaky faucet under your kitchen sink.
Where we work
In their words
“Came out same day for a leak and ended up handling our water heater too. Fair price, clean work.”
“We use them across three of our properties now. Reliable for everything from small repairs to bigger jobs.”
“Showed up when they said, explained the options, didn’t upsell. Hard to find these days.”
