Our Capabilities

What Separates Precision Pipe Repair from Guesswork

Our techs work on every pipe material found in San Ramon, CA homes, from pre-1970s galvanized to modern PEX-A crosslinked systems. The repair method matches the pipe.

🔊

Acoustic Leak Detection

Pressurized water escaping a pipe creates a characteristic acoustic signature. Our listening devices amplify ground and structure-borne sound to pinpoint a leak location within inches — through concrete slabs, behind drywall, or under flooring. This means we open only the section of wall, floor, or slab directly over the failure.

🌡️

Thermal Camera Scanning

We use thermal imaging as a complement to acoustic detection — particularly useful for slab leaks and leaks inside insulated wall cavities where sound transmission is reduced.

🛠️

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

What We Fix — Pipe by Pipe, Material by Material

Pipe failures have different causes depending on material type, age, water chemistry, and installation history. Here's how we address each category.

Copper

Copper Pipe Repair & Repipe

Copper failures most often involve pinhole corrosion in soft copper tubing from aggressive water chemistry, failed soldered joints, or fatigue cracks at fittings in high-vibration locations. We locate the failure precisely, cut out the failed section, and install either a sweated repair coupling or a press-fit connector — both rated to ASTM B88 standards for potable water service.

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

Cross-linked polyethylene (PEX) is the current standard for residential supply piping. Failures are uncommon but occur at crimp or clamp fittings that were improperly installed, at pipe runs exposed to UV degradation, or at locations where the pipe was kinked during installation. We repair using expansion fittings (for PEX-A) or crimp fittings with the correct ring size for the pipe diameter.

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

Supply line leaks under a concrete slab are identified by acoustic detection and confirmed by thermal imaging. Once located, we evaluate three repair options: direct-access repair (jackhammering to the pipe, repairing the section, and patching the slab); rerouting the line through the wall framing above slab to bypass the failed underground run; or epoxy pipe lining for older copper systems with systemic pinhole corrosion.

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.

Our Process

How Our Pipe Repair Process Works in San Ramon, CA

We don't open walls at random. Acoustic and thermal detection tools tell us exactly where to cut before we pick up a saw.

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.

Pressure Test & Acoustic / Thermal Detection

This detection step routinely saves homeowners $500–$2,000 in unnecessary drywall removal compared to opening walls speculatively.

Flat-Rate Quote & Minimal Access Opening

You receive a flat-rate quote covering the specific repair based on what the detection confirmed. We open only what needs to be opened — typically a 12–18 inch drywall or flooring access, not a full wall section.

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

Real Pipe Repair Reviews from San Ramon, CA Homeowners

★★★★★

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, San Ramon

★★★★★

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, San Ramon, CA

★★★★★

Pipe burst in a rental property at 2 AM — Masters Plumbing Service's emergency line answered immediately, talked my tenant through the main shutoff, and had a tech there in 45 minutes. Freeze crack in a PEX line in an exterior wall. Repair and insulation wrap done in under two hours. Detailed receipt for insurance documentation. Exactly what I needed as a landlord dealing with a crisis remotely.

Common Questions

What to Know Before Calling for Pipe Repair in San Ramon, CA

A slow pinhole leak inside a wall can run for months before surface damage appears. By the time you see a stain, the moisture intrusion is typically already significant. If your meter shows movement with everything off, call us — we can pressure-test and locate it before it becomes a major remediation project.

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.

Galvanized pipe corrodes from the interior outward — by the time one section fails, the rest of the pipe is in varying stages of the same process. A localized repair buys time, but another section typically fails within 1–3 years if the system is at end of life. The honest answer is: it depends on how far along the corrosion is and how many sections are already narrowed or showing surface rust.

We don't rush pressure testing at the end. That's the step that confirms the repair is actually complete, and it takes the time it takes.

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.
