Once a leak is found, the repair should be permanent, not a clamp that buys a few months. We cut out the damaged section, replace it with proper fittings, pressure test the line and leave the area ready for drywall or flooring repair.
The causeWhy it happens
Leaks appear where pipes are weakest: at joints, fittings and spots worn thin by flow or corrosion. Pinhole leaks in copper, cracked fittings, worn valve packing, failed compression connections and burst supply hoses under sinks or behind washers are the most common. A small leak in a wall can run long enough to soak insulation and studs before anyone notices.
DiagnosisWhat we check first
- 01Pipe condition around the leak
- If the pipe near the leak is thin or pitted, we extend the repair to sound pipe.
- 02Material and fittings
- We match the repair to the existing material, copper, PEX or CPVC, using appropriate transitions.
- 03Cause
- A leak caused by high pressure or water hammer will repeat unless the cause is corrected.
- 04Pattern of repeat leaks
- Several pinholes in a short time suggests the system may be approaching the point where a repipe makes sense.
The optionsWhich repair fits, and when
We lay out the choices plainly, explain what each involves and leave the decision with you.
Section repair
Cut out the damaged pipe and replace it with new pipe and fittings. The most common fix.
Valve or connector replacement
A leaking stop valve, hose bib, supply line or washing machine valve is replaced outright.
Reroute
The leak is in a hard-to-reach spot, such as under a slab. A new line routed through the attic or wall may be more practical.
Local conditionsPlumbing Leak Repair on the west side of San Antonio
San Antonio's mineral-heavy water and high municipal pressure in some neighborhoods both wear on copper and fittings. If your home has had more than one pinhole leak, we check static water pressure and recommend a pressure regulator if it is running high, which protects the repair and everything else on the system.

A few things that help
Shut off the water at the main or at the fixture stop valve if the leak is active. Move valuables away from the affected area. Note how long you think the leak has been running.
QuestionsCommon questions about plumbing leak repair
Do you repair the drywall too?
We make clean openings and leave them ready for patching. Drywall finishing is a separate trade, and we can tell you what to expect.
Is a pipe clamp a permanent fix?
No. Clamps are for temporary emergencies. A permanent repair replaces the damaged section.
Why do I keep getting pinhole leaks?
Water chemistry, high pressure, high velocity or aging copper. If leaks keep appearing, a repipe may be the more sensible solution.
