Pipe Repair: Copper, PEX, Cast Iron in Whitby
A pinhole, a joint that weeps, a fitting gone green: each is minor on its own that can quietly soak a subfloor. Repair is usually straightforward once the pipe material is known.

Signs, filed under symptoms
- Green or white crust around a copper joint
- A drip from a fitting under a sink
- Rust spots on galvanized pipe
- Water staining below a run of pipe
How the job is handled
We identify the material first: copper, galvanized steel, PEX, CPVC, or polybutylene. Each has its own repair method. One pinhole in copper is fixed by removing a few inches and sweating in new tube; repeated pinholes along the same run suggest the whole run should be replaced.
We check water pressure too. Pressure above roughly 80 psi stresses joints and may justify a pressure-reducing valve.
Signs you need this work
- Green crust on a copper joint
- Pinhole spray from a copper line
- Weeping from a cast-iron hub
- PEX fitting dripping at a crimp ring
What the plumber brings
Tools and parts that come in from the truck for this kind of call, so the fix can usually be made on the first visit:
- Tubing cutters and torch
- PEX crimp and expansion tools
- No-hub couplings and snap cutter
- Pressure gauge
The job, step by step
- 01
Water is shut off and lines are drained
- 02
The leaking section or fitting is cut out
- 03
A matching repair is made in copper, PEX or no-hub
- 04
The line is re-pressured and every new joint is checked
- 05
We note the condition of the pipe on either side
Symptom, cause and fix
| What you see | Usual cause | What we do |
|---|---|---|
| Pinhole in copper | Corrosion from water chemistry or electrolysis | Replace the section; check for more |
| Cast-iron crack | Rusted wall at a seam or hub | Cut out and couple in PVC |
| PEX fitting leak | Poor crimp or wrong ring | Cut and re-make the fitting |
Local card: Whitby houses
Older Whitby homes sometimes mix materials from several renovations, so a single basement can contain copper, galvanized and plastic pipe joined together. Mixed connections need the right transition fittings to avoid corrosion.
The visit, in order
- Pipe material and fault identified
- Water isolated and line drained
- Section replaced with correct fittings
- Pressure checked and joints tested
Ring us when
Call at the first sign of a drip or stain. Small leaks rot wood and grow mould long before they look serious.
Common questions
Is a clamp a permanent fix?
A repair clamp is a useful temporary measure. A proper cut-out repair is the lasting solution.
Why does my copper keep leaking?
Water chemistry, high velocity and pressure can all contribute. Repeated pinholes usually mean the run is due for replacement.
