Water service line replacement and repair
The water service line brings drinking water from the street to your house. The section between your property line and the building is yours — the City handles its own.
It is a component nobody ever sees and rarely replaces, which means many South Shore homes still have their original line. In sectors built before 1980, in Saint-Lambert, Longueuil or Saint-Bruno, that is a sizeable share of the housing stock.
Gradual pressure loss, a climbing water bill or damp ground above the route are the usual signs.
Does this sound familiar?
- Water pressure has dropped gradually throughout the house
- The water bill is rising with no change in habits
- The ground is damp or sinking above the line's route
- Water is cloudy or rusty when taps are first opened
- The house is old and the service line has never been replaced
- The meter moves with everything shut off
How we work
We confirm the problem is there
Pressure loss can come from a stop valve, a scaled water heater, or the line itself. We rule out interior causes before discussing excavation.
We locate the line and the leak
The route and leak point are located before digging, so we open the right spot rather than the whole length.
We replace the private portion
The line is replaced between the property line and the building, with an accessible stop valve and a compliant connection.
We recommission and verify
Pressurise, check flow at several points in the house, and confirm no leak remains at the joint.
