What lead water service replacement involves
The water service runs from the City's valve near the property line, under your yard, through the foundation to the main shut-off and meter. We replace the private portion with copper or approved plastic tubing, usually by trenchless pulling or a narrow trench, and seal the new line through the foundation wall. A new main shut-off goes in at the same time.
| Step | Detail |
|---|---|
| Confirm material | Scratch test near the meter: lead is soft and dull grey, with bright metal under a scratch |
| Coordinate with the City | The City replaces its own side, and has offered programs; check current terms |
| Permit | A plumbing permit is usually required |
| Restore | Backfill, and patch the foundation penetration |
Why North York houses need it
Lead was common for water services until the mid-1950s in Toronto. Hillcrest Village and parts of North York built before that period may still have it, and some houses that were later renovated kept the original line from the street. A house built later is unlikely to have lead, but a scratch test is the only way to be sure.
Plumber's tip: Until the line is replaced, let the cold tap run a couple of minutes after water has sat overnight, use only cold water for cooking and drinking, and think about a filter rated to reduce lead.
How we write up the job
The order records the existing material, the new line material and size, the path and depth, the permit number, and the coordination with City crews. We also note the new valve type at the meter so you know how to close it. If your building is a condo, read our condo leaflet: services are usually common elements.
Signs you should call
- The pipe entering the house is soft grey metal.
- The City has told you the street side is being replaced.
- A water test showed lead above the drinking water standard.
- You are expecting a baby or have young children in the house.
We usually pair this with a new main shut-off valve.
Costs and what affects them
Length of the run, depth, obstacles such as driveways and trees, and the method chosen set the price. Any City rebate or program has its own rules; we give you paperwork to support an application.

Your questions on this one
Does a filter remove lead?
A filter certified for lead reduction can help, but it is a stopgap until the pipe is replaced.
Does the front lawn get torn up?
Trenchless methods often avoid a full trench. Some digging at each end is usually needed.
