Our Capabilities
How Masters Plumbing Service Approaches Pipe Repair in Saint Helena
The biggest cost variable in pipe repair isn't parts — it's how much structure gets opened to find and access the failure. Precise pre-repair location tools reduce that cost significantly.
🔊
Acoustic Leak Detection
Acoustic detection is most effective on pressurized supply lines. Combined with a pressure test to confirm water loss before we start, it tells us both that there's a leak and exactly where it is.
🌡️
Thermal Camera Scanning
Active water leaks create temperature differentials on wall and floor surfaces detectable with an infrared camera. A slow leak inside a wall shows as a cold, spreading zone; a hot water line leak shows the inverse. Thermal imaging confirms leak presence and approximate location before any cutting begins.
🛠️
All Pipe Materials & Joining Methods
Press-fit copper connections — particularly useful for repairs in occupied spaces where open flame is a concern — are available as an alternative to torch sweating where code permits.
🔒
Pressure-Tested Before We Leave
Every supply line repair is pressure-tested before we close the wall or floor. We pressurize the repaired section, hold the test pressure for the required duration, and confirm zero drop before considering the repair complete. You don't find out there's a second leak next week — we find it before we pack up.
Our Pipe Repair Services
Every Pipe Repair Type We Handle in Saint Helena, CA
From a pinhole copper leak behind a kitchen cabinet to a full galvanized repiping, our pipe crew in Saint Helena, CA handles the full range.
Copper
Copper Pipe Repair & Repipe
Pitting corrosion in copper is sometimes systemic rather than localized — a single pinhole is often the first of several to appear. When the camera or pressure test finds multiple deteriorated sections, we give you an honest assessment of whether targeted repair or full copper repipe is the better long-term answer.
Galvanized
Galvanized Pipe Replacement
Galvanized steel pipe was standard in homes built before the 1960s. It corrodes from the inside out — zinc coating depletes, iron oxide (rust) accumulates on the inner wall, progressively narrowing flow and leaching into the water supply. Repairs on severely corroded galvanized are generally temporary; the pipe is failing systemically along its full run.
PEX
PEX Pipe Repair & Extension
PEX is also the material of choice for extending or reconfiguring supply runs during remodel work. Its flexibility reduces fitting count and eliminates the need for torch work inside walls.
Burst Pipes
Burst & Freeze-Damaged Pipe Repair
A burst pipe from freezing or sudden pressure surge requires immediate water shutoff and precise repair. We locate the failure, determine whether it's a single failure point or multiple freeze-damaged sections, and repair with a method appropriate to the pipe material — press-fit coupling for copper, expansion coupling for PEX-A, or a mechanical repair coupling for emergency situations.
Slab Leaks
Under-Slab Pipe Leak Repair
Slab leak rerouting is often more cost-effective than direct access, particularly for longer runs or under tiled floors. We present the options honestly with pricing so you can choose based on your priorities.
Full Repipe
Whole-House Repipe Service
When galvanized supply lines are at end of life or polybutylene pipe (recalled for chronic failure) is in the home, a full repipe with PEX or copper is the permanent solution. We run new supply lines through the structure, transition all fixture connections, pressure test the entire new system, and patch access points in walls and ceilings.
Here's how a Masters Plumbing Service pipe repair call plays out in Saint Helena, CA.
1
Call & Describe — We Shut the Water If Needed
Active leak? Our dispatcher walks you through shutting off the main supply valve while we drive to you. Describing what you see — water stain on a ceiling, drop in water pressure, wet flooring — helps us arrive with the right detection tools loaded.
2
Pressure Test & Acoustic / Thermal Detection
We pressurize the supply system and monitor for pressure drop to confirm an active leak. Then acoustic listening devices and the thermal camera locate the failure to within a small area — telling us which section of wall, floor, or slab to open.
3
Flat-Rate Quote & Minimal Access Opening
For slab leaks, we present repair, reroute, and lining options with pricing so you can make an informed choice before any concrete is cut.
4
Repair & Pressure Test — Then You're Done
You receive a written summary of what failed, what we installed, and the warranty terms before we leave.
Customer Reviews
What Saint Helena Customers Say About Our Pipe Work
★★★★★
My older home had a copper supply line fail inside an exterior wall. The thermal camera showed the wet zone through the drywall without any cutting. They opened a 10-inch section right at the pinhole, put in a press-fit repair coupling — no torch in my wall — pressure tested, and patched the drywall themselves. Two hours total.
— N. Bergman, Saint Helena
★★★★★
Had an under-slab leak diagnosed by Masters Plumbing Service with acoustic equipment. They found the leak at 6 feet from the wall — a single copper elbow that had developed a pinhole. Presented three options: direct slab access, reroute through the wall framing above, or copper lining. I chose the reroute — they ran a new PEX line through the crawl space and connected at both ends without touching the slab. Pressure tested, verified no remaining drop. No jackhammering at all.
— O. & R. Adeyemi, Saint Helena, CA
★★★★★
I noticed my water meter spinning with all fixtures off — confirmed a leak in the supply system. Masters Plumbing Service ran a pressure test and acoustic scan, found a pinhole in a copper section under the slab in the utility room. They rerouted the line through the wall above slab, tested, and closed out the permit. The reroute was exactly the same cost as direct slab access would have been, but no damaged floor tile.

Common Questions
Pipe Repair Questions We Answer Every Day
Watch your water meter with all fixtures off. If the meter dial is moving or the leak indicator light is turning, water is escaping somewhere in your supply system. Other signs: unexplained increases in your monthly water bill, soft or discolored spots on walls or ceilings, mold or mildew smell in a room without a visible source, or a running sound inside walls when all fixtures are off.
In most cases, the pipe itself needs to be physically accessed to make a durable repair — but the amount of wall we open depends entirely on how precisely we can locate the failure first. With acoustic detection and thermal imaging, we typically open a single, small access point rather than a wide section of wall.
A slab leak is a supply line or drain line failure in a pipe that runs through or under the concrete foundation slab. Supply line slab leaks are the more urgent scenario — pressurized water escaping under the slab saturates the subgrade, can undermine the foundation, and drives significant water bills.
We assess galvanized condition when we're on-site — visible exterior corrosion, interior scale visible at the cut failure point, and water pressure readings all tell us how advanced the system deterioration is. We give you the repair-vs-repipe math honestly so you can make the decision that fits your timeline and budget.
A single localized pipe repair — finding and fixing one failure point — typically takes 1.5–3 hours including detection, access, repair, and pressure testing. Slab leak reroutes run 3–5 hours depending on the routing path and pipe length. A full-house repipe is a multi-day project — typically 2–4 days for a standard single-family home depending on size and pipe count.
For slab access openings, we clean up concrete debris, complete the pipe repair, and patch the concrete. Tile or flooring restoration over a slab patch is normally a separate trade.
