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

Our techs work on every pipe material found in Pasadena, TX homes, from pre-1970s galvanized to modern PEX-A crosslinked systems. The repair method matches the pipe.
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.
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.
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.
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 β we find it before we pack up.
From a pinhole copper leak behind a kitchen cabinet to a full galvanized repiping, our pipe crew in Pasadena, TX handles the full range.
Pitting corrosion in copper is sometimes systemic rather than localized β a single pinhole is often the first of several to appear. When the camera or pressure test finds multiple deteriorated sections, we give you an honest assessment of whether targeted repair or full copper repipe is the better long-term answer.
Galvanized steel pipe was standard in homes built before the 1960s. It corrodes from the inside out β 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 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.
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 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.
A full repipe in Pasadena 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 Pasadena, TX.
For emergency burst pipe calls, we dispatch immediately. For suspected slow leaks, we schedule at the earliest available slot and confirm before arrival.
This detection step routinely saves homeowners $500β$2,000 in unnecessary drywall removal compared to opening walls speculatively.
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 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.

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 β 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.
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.
I noticed my water meter spinning with all fixtures off β 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.
