Our Capabilities
What Separates Precision Pipe Repair from Guesswork
The biggest cost variable in pipe repair isn't parts β it's how much structure gets opened to find and access the failure. Precise pre-repair location tools reduce that cost significantly.
π
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 β through concrete slabs, behind drywall, or under flooring. This means we open only the section of wall, floor, or slab directly over the failure.
π‘οΈ
Thermal Camera Scanning
We use thermal imaging as a complement to acoustic detection β particularly useful for slab leaks and leaks inside insulated wall cavities where sound transmission is reduced.
π οΈ
All Pipe Materials & Joining Methods
Press-fit copper connections β particularly useful for repairs in occupied spaces where open flame is a concern β are available as an alternative to torch sweating where code permits.
π
Pressure-Tested Before We Leave
Drain line repairs are water-tested by running fixtures through the repaired section and visually confirming no seepage at the repair joint and downstream.
Our Pipe Repair Services
What We Fix β Pipe by Pipe, Material by Material
From a pinhole copper leak behind a kitchen cabinet to a full galvanized repiping, our pipe crew in Duarte, 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 β both rated to ASTM B88 standards for potable water service.
Galvanized
Galvanized Pipe Replacement
We replace galvanized supply lines with copper or PEX β 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 β 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
A full repipe in Duarte typically completes in 2β3 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 Duarte, CA.
1
Call & Describe β 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 β water stain on a ceiling, drop in water pressure, wet flooring β helps us arrive with the right detection tools loaded.
2
Pressure Test & Acoustic / Thermal Detection
This detection step routinely saves homeowners $500β$2,000 in unnecessary drywall removal compared to opening walls speculatively.
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 β Then You're Done
Repair executes immediately on approval. After the repair, we repressurize and hold a pressure test to confirm the failure is fully resolved β not partially. The access opening is left clean for your drywall patch or left ready for your contractor.
Customer Reviews
What Duarte Customers Say About Our Pipe Work
β β β β β
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 β no torch in my wall β pressure tested, and patched the drywall themselves. Two hours total.

Our galvanized supply lines finally gave out β 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.

Pipe burst in a rental property at 2 AM β 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 Duarte, CA
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 some cases β particularly for older copper systems with multiple pinhole failures along a supply run β 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 β 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.
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 β 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.
