Leak Detection & Repair
A damp spot or a climbing water bill means something's leaking where you can't see it. We find it without tearing up your house, and fix it right.
Does This Sound Familiar?
- A water bill that's climbed for no obvious reason
- A damp spot, stain, or musty smell with no visible source
- The sound of running water when nothing's on
- Warm spots on the floor (slab leak)
- Low pressure in part of the house
- A pipe that's leaked more than once in the same area
What's included
- 1
Locate the leak
We use acoustic and pressure testing to pinpoint the leak without guessing or demolition.
- 2
Show you the source
We mark the exact location and explain what's failing and why — corroded pipe, joint, or fitting.
- 3
Repair or repipe
For a single failure we spot-repair; for systemic corrosion we quote a targeted repipe of that run.
- 4
Pressure-test and restore
We pressure-test the line, then close up access cleanly and document the work.
Upfront, Flat-Rate, No Surprises
Flat-rate detection with a clear quote for the repair.
Detection fee credited toward a repipe if that's the recommendation.
Repipe quotes are section-by-section so you understand exactly what's being replaced.
Repair vs. Replace
The factors that push a job one way or the other — straight, no pressure.
- One isolated failure in otherwise sound pipe is a spot repair.
- Repeated leaks, green corrosion, or old galvanized pipe point to a repipe.
- A whole-home repipe is a big decision — we give you an honest read on whether you're there yet.
