What we do

Whatever's leaking or clogged, handled.

One licensed local crew for your whole home: upfront flat-rate pricing, and every job pressure-tested before we leave.

Drain cleaning & jetting

Slow drains, backups and grease lines cleared with cable or high-pressure jetting, and a camera locate when it's the sewer.

From $185

Water heater repair & replace

Tank and tankless: diagnosed, replaced and code-compliant, with the T&P valve and expansion tank done right.

Repipe & leak repair

We find the leak, fix it right, and pressure-test before we leave, from a single line to a whole-home repipe.

Sewer camera & fixtures

Camera locate to find the real problem, plus faucet, toilet and disposal installs. Fast, clean, and tested.

From $175
The Mainline difference

A tested, documented report after every call.

No more wondering if the fix will hold, or whether a permit was even pulled. The moment a plumber finishes, you get a photo of the old and new parts, the GPS, the pressure-test result, and the permit number, on the record forever.

  • Old part vs. new part, on the record. Every replacement is photographed and GPS-stamped. See exactly what we pulled out and what went in.
  • Tested before we leave. The pressure-test, the no-leak check and the permit number, logged for your home and any inspector.
  • Workmanship warranty. Something not draining or holding pressure? We come back and make it right, on us.

"Showed up on time, replaced our water heater the same day, and texted me photos of the old tank and the new one with the pressure reading. I knew exactly what I paid for."

"Sewer was backing up. They camera'd the line, showed me the offset joint on screen, pulled the permit and fixed it. No other plumber walked me through it like that."

"Same plumber every time, fair flat-rate pricing, and they actually show up in the window they give you. Been using Mainline for years and won't switch."
