The material matters. Copper, PEX, CPVC, galvanized steel and polybutylene all fail in different ways, and a plumber's recommendation will depend on what is in your walls.
If a pipe is leaking right now
- Close the nearest fixture valve or the main water shutoff.
- Keep away from water near outlets and electrical equipment.
- Open a low faucet to drain remaining water from the lines.
- Catch drips, move belongings, and photograph damage.
- If a ceiling is bulging, place a bucket below and stay out from under it.
What this service solves
- Pinhole leaks in copper
- Leaking joints and fittings
- Burst and frozen pipes
- Corroded galvanized lines
- Noisy or banging pipes (water hammer)
Common symptoms
- Water stains on ceilings or walls
- Damp cabinet floors under sinks
- Higher water bills without changes in use
- Rust-colored or discolored water
- Low pressure at some fixtures
- Banging when faucets close
Most likely causes
Corrosion
Galvanized steel rusts from the inside, narrowing the pipe and eventually leaking. Copper can develop pinholes, often related to water chemistry or high velocity.
Freezing
Water expands as it freezes. The pressure that splits a pipe usually builds between the ice blockage and a closed faucet, which is why breaks often appear away from the frozen spot.
High water pressure
Pressure above the commonly recommended maximum of about 80 psi stresses joints, valves and supply hoses.
Failing materials
Polybutylene, a gray plastic pipe used in many homes from the late 1970s to mid-1990s, is prone to failure at fittings and is often replaced rather than repaired.
Mechanical damage
Nails, screws, settling and unsupported pipe runs can all cause leaks.
How the problem is diagnosed
- Check the water meter with fixtures off to confirm a supply leak.
- Trace staining and moisture with a moisture meter or thermal camera.
- Isolate sections with valves where possible to narrow the location.
- Identify the pipe material so the repair uses compatible fittings.
Repair and replacement options
| Option | Best for | What to know |
|---|---|---|
| Section replacement | One damaged length of pipe | Cut out the damaged section and join new pipe with soldered, crimped, press or push-to-connect fittings as appropriate. |
| Fitting or valve replacement | Leaks at joints | Many leaks are at a fitting, not the pipe itself. |
| Reroute | Pipes in hard-to-reach or freeze-prone locations | Running new pipe through a better path instead of repairing in place. |
| Repiping | Multiple failures or problematic material | Replacing the supply system when spot repairs no longer make sense. |
What a plumber normally does
- Shut off water and drain the section.
- Open access and confirm the failure.
- Repair with compatible materials.
- Pressure-test and check for leaks before closing walls.
Emergency warning signs
- Water spraying or flowing from a pipe
- Bulging, wet ceilings
- Water near the electrical panel
If you see any of these, shut off water first. See emergency plumbing steps.
What affects the cost
We don’t publish national price figures because real quotes vary too much by region, access and the condition of your system. These are the factors that move the price:
- Pipe material
- Location and access (open basement versus finished ceiling or slab)
- Number of leaks
- Wall and ceiling repair after access
- Permits for larger reroutes or repiping
Ask for a written quote that names the method, materials and any permit or restoration work before work begins.
DIY vs. calling a professional
Reasonable for homeowners
- Replacing a sink or toilet supply hose
- Using a temporary repair clamp to slow a leak until a plumber arrives
- Insulating exposed pipes
Call a professional for
- Leaks inside walls, ceilings or slabs
- Soldered copper repairs near framing
- Polybutylene or galvanized systems
- Any repair that must pass inspection
Prevention and maintenance
- Install a pressure-reducing valve if pressure is consistently high.
- Insulate pipes in unheated spaces.
- Disconnect garden hoses before freezing weather.
- Watch for recurring pinhole leaks, which often signal a system-wide problem.

Learn more →Pipe Repair: common questions
When should pipes be replaced instead of repaired?
Consider repiping when leaks keep appearing in different places, the pipe is galvanized steel or polybutylene, water is discolored from corrosion, or pressure is poor because pipes are narrowed inside.
What causes pinhole leaks in copper pipe?
Pinhole leaks are often linked to water chemistry, high flow velocity or certain installation practices. One pinhole may be isolated; several in different places suggest the system is deteriorating.
Why do my pipes bang when I turn off a faucet?
That sound is usually water hammer: water stopping suddenly and creating a pressure shock. High pressure, loose pipe straps or fast-closing valves cause it. Arrestors and pressure regulation usually fix it.
Can a leaking pipe be fixed without cutting the wall?
Sometimes. If the leak is at an accessible fitting or the pipe can be reached from a basement or attic, no wall opening is needed. Leaks inside a closed wall usually require a small access opening.
Is PEX better than copper?
Each has trade-offs. PEX is flexible, resists freeze splitting better and needs fewer fittings. Copper is long-proven and tolerates heat and UV. Many repipes now use PEX for cost and installation speed.
What does polybutylene pipe look like?
Polybutylene is usually gray, sometimes white or black, and often stamped PB2110. It was common in homes built from the late 1970s to the mid-1990s.
