Finding and Fixing the Actual Leak
Pipe leak repair starts with locating the leak, which sounds obvious until you've chased a wet ceiling stain three feet from where the water is actually coming in. Water travels along joists and pipe runs before it drops, so the stain tells you where it landed, not where it started. Call [(301) 834-2944](tel:+13018342944) and we'll find the fault before opening anything up.
A pinhole in copper is a repair rather than a re-pipe. So is a failed joint or a split flex line under a sink. When a run is failing repeatedly in different spots, that's the point at which [repiping](/services/repiping) becomes the honest recommendation, and we'll say so rather than patching indefinitely.

Why Copper Develops Pinholes
Pinhole leaks in copper aren't a sign you did anything wrong. They form from the inside out, which is why the first evidence is usually a drip or a stain rather than anything you could have spotted. Once one appears in a run, others in the same run become more likely, because whatever caused the first is acting on the whole length.
That's the useful diagnostic. A single pinhole in an otherwise sound system gets soldered and forgotten. Three in two years on the same horizontal run means the run is telling you something, and replacing that section beats repairing it a fourth time.
Polybutylene is a different story. It went into homes roughly between 1978 and 1995 and it typically fails at the fittings rather than along the pipe. If that's what you have, a repair is often just the fitting, and we'll tell you whether the rest looks sound.

Act Early on This One
A slow leak into a cavity is more expensive than a fast one, because a fast leak forces you to deal with it. Water sitting in a wall or under a floor rots the subfloor and gets into insulation, and the repair grows from a fitting into carpentry.
If you can hear water with everything off, or a ceiling stain is bigger this week than last, that's a call today rather than a call eventually. Close your main shutoff and reach (301) 834-2944.
One worth ruling out first: condensation. A cold supply line or a cold tank in a humid basement drips convincingly and isn't a leak at all. We'll tell you that on the phone rather than charging you to find out.

FAQ Common questions
Frequently Asked Questions
Answers below
Can you repair a pinhole leak without replacing the whole pipe? +
Usually yes. A single pinhole in otherwise sound copper is a section repair. What changes the answer is repetition: several pinholes in the same run over a short period means the run itself is failing, and replacing that length is cheaper than returning for each new leak.
My ceiling is stained but the bathroom above looks fine. Where's the leak? +
Water runs along joists and pipe runs before it drops, so the stain marks where it landed rather than where it entered. That's exactly the case for locating the leak before cutting, because a guess means a larger opening and a second hole when the guess is wrong.
Is a higher water bill enough to prove I have a leak? +
It's a strong signal, particularly if nothing changed about how much water you use. Check your meter with every fixture off; if it's still moving, water is going somewhere. Underground and under-slab leaks show up this way long before anything is visible.
Do you repair polybutylene? +
Yes. It generally fails at the fittings, so many repairs are a fitting rather than a length of pipe. If yours is failing in multiple places, we'll be straight with you about whether continuing to patch it makes sense.
