Signs you need pipe repair
- Pinhole spray or green crust on copper lines
- Water marks on a ceiling below a bathroom or kitchen
- A crimp ring or fitting weeping on PEX
- Rust weeping from galvanized nipples or unions
- The water meter dial creeping while every tap is closed
Dripping from a drain pipe usually shows up only when a fixture is used. Supply leaks run all the time because the line is under pressure. Knowing which you have narrows the search.
How we handle the job
We shut the water, open only as much wall or ceiling as the repair needs, and cut back to sound pipe. Copper gets a soldered or pressed coupling; PEX gets new fittings; damaged galvanized is replaced with modern material and proper transition fittings rather than another threaded patch. Afterwards we restore pressure, watch the joint and leave the opening clean for your drywall trade.
If the leak cannot be traced visually, leak detection uses moisture readings and listening tools to avoid opening walls by guesswork.
Bay Ridges and other post-war streets still have some galvanized steel, often mixed with copper from past renovations.
Pickering homes and this problem
Bay Ridges and other post-war streets still have some galvanized steel, often mixed with copper from past renovations. Amberlea and Liverpool homes from the late 1970s and 1980s mostly run on copper that is now reaching the age where pinholes appear. Newer builds in the north end are PEX, where failures tend to come from fittings or nail punctures rather than the pipe itself. Winter also brings split pipes in exterior walls and garages; for those, see frozen pipe repair.
What affects the cost
- How the pipe is reached: open joists in an unfinished basement versus a tiled shower wall
- Pipe material and diameter
- Whether a shut-off valve needs replacing so the house can be isolated
- Emergency or after-hours timing
After the repair
Once the joint is holding, we look along the rest of the visible run for green staining, damp insulation and old repair clamps. If anything else looks marginal, we point it out rather than letting it wait for the next leak. You will also get a note of the pipe material, the repair method and the location, which is useful for insurance and for whoever works on the house next. Drywall and paint are left to you or your contractor, with the opening kept tidy and as small as we could manage.
What you can do first
Close the main shut-off. Know where it is before you need it; if it is seized, a main shut-off valve replacement is worth doing on a quiet day. Run a tap on the lowest floor to bleed off pressure, move belongings out of the drip line and turn off breakers for any wet light fixtures. A bucket and a towel buy time; tape and clamps are a temporary fix only.
Questions callers ask
Can a pinhole leak be patched with a clamp?
A repair clamp can hold for a short time in an emergency, but the pipe around a pinhole is usually thin as well. Cutting in a proper coupling is the lasting repair.
Why does my copper keep springing leaks?
Age, water chemistry, high velocity and poor grounding practices can all wear copper from the inside. Repeated leaks in one area suggest replacing that section.
