Our Capabilities

How Masters Plumbing Service Approaches Pipe Repair in Union

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

Drain line repairs are water-tested by running fixtures through the repaired section and visually confirming no seepage at the repair joint and downstream.

Pipe Repair Solutions for Union 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

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

From Leak to Fixed Pipe — 4 Precise Steps

Here's how a Masters Plumbing Service pipe repair call plays out in Union, MO.

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.

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

For slab leaks, we present repair, reroute, and lining options with pricing so you can make an informed choice before any concrete is cut.

Repair & Pressure Test — 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 — not partially. The access opening is left clean for your drywall patch or left ready for your contractor.

Customer Reviews

What Union Customers Say About Our Pipe Work

★★★★★

Water stain appeared on my kitchen ceiling from the bathroom above. I expected them to tear up the entire bathroom floor. Instead the tech ran a pressure test, found a 12% pressure drop over 10 minutes, then used the acoustic device and identified the leak at a failed sweat joint in the copper supply to the toilet — accessible through a 14-inch drywall cut in the ceiling below. Repair was maybe $280 including the detection. I'd been dreading a $2,000 floor demo.

— N. Bergman, Union

★★★★★

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, Union, MO

★★★★★

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

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.

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.

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.
