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 Mountain View, 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 Mountain View, CA

Our techs work on every pipe material found in Mountain View, 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

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

Pipe Repair Solutions for Mountain View Homes

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

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

We also inspect upstream of the burst for additional sections that froze but haven't yet failed — because a partially-thawed line sometimes shows multiple failure points only after pressure is restored.

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.

Our Process

Locate It, Quote It, Fix It, Test It

Here's how a Masters Plumbing Service pipe repair call plays out in Mountain View, CA.

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

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.

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

Masters Plumbing Service Pipe Repair — How We Handle It

★★★★★

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, Mountain View

★★★★★

Our galvanized supply lines finally gave out — low pressure everywhere, rust-colored water at some fixtures. Masters Plumbing Service repiped the whole house with PEX over two days. They confirmed pressure and flow at every fixture before leaving, patched all the wall access points smooth, and cleaned up each work area. One year later, no issues at all.

— O. & R. Adeyemi, Mountain View, 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

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.

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.

Our pipe repair quote includes clean access cuts and leaving the opening ready for patching — with a clean, straight cut that accepts a standard drywall patch. We can typically patch the access opening as part of the job on request, though finish painting and texture matching are typically handled by the homeowner or a drywall contractor for best cosmetic results.
