Pipe Repair in Angwin, CA — All Pipe Materials, Same-Visit Repairs
Pipe failures range from a slow pinhole leak weeping inside a wall to a full main line rupture. Locating the failure precisely — before opening drywall or digging — is the skill that separates a clean, affordable repair from an expensive and destructive guessing operation. Masters Plumbing Service's pipe technicians in Angwin, CA use acoustic listening devices and thermal imaging cameras to find the leak first, then open only what needs to be opened.

Our Capabilities
4 Things That Define Our Pipe Repair Service in Angwin, CA
Our techs work on every pipe material found in Angwin, CA homes, from pre-1970s galvanized to modern PEX-A crosslinked systems. The repair method matches the pipe.
🔊
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
Our techs are proficient in copper sweating (soldering), press-fit connections (ProPress system), CPVC solvent welding, PEX crimp and expansion fitting installation, threaded galvanized repair, and ABS/PVC drain line work. We match the repair method and material to the existing pipe system rather than forcing incompatible transitions.
🔒
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 Angwin, CA
From a pinhole copper leak behind a kitchen cabinet to a full galvanized repiping, our pipe crew in Angwin, CA handles the full range.
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
We replace galvanized supply lines with copper or PEX — either as targeted section replacement at active failure points or as a full-house repipe project. We connect the new material to existing fittings using dielectric unions where code requires to prevent galvanic corrosion at copper-to-galvanized transitions.
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
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
A full repipe in Angwin typically completes in 2–3 days for a standard single-family home. You're without water for a portion of each day; we plan the schedule to minimize disruption to occupied rooms.
Here's how a Masters Plumbing Service pipe repair call plays out in Angwin, CA.
1
Call & Describe — We Shut the Water If Needed
For emergency burst pipe calls, we dispatch immediately. For suspected slow leaks, we schedule at the earliest available slot and confirm before arrival.
2
Pressure Test & Acoustic / Thermal Detection
This detection step routinely saves homeowners $500–$2,000 in unnecessary drywall removal compared to opening walls speculatively.
3
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.
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
Real Pipe Repair Reviews from Angwin, 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, Angwin
★★★★★
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.

★★★★★
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 FAQ for Angwin, CA Homeowners
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 some cases — particularly for older copper systems with multiple pinhole failures along a supply run — rerouting the line through accessible framing rather than repairing it in place is more practical and more permanent. We present both options when they're both viable.
Repair options include direct slab access (jackhammer to the pipe, repair, patch), rerouting the supply line above slab through framing, and for copper systems with multiple pinhole failures, epoxy pipe lining from inside the pipe without excavation. We use acoustic and thermal detection to locate the leak before recommending a repair approach.
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.
