Water Service Line Replacement for Homes Across the GTA

The pipe from the curb stop to your basement wall carries every litre the house uses. When it is undersized, corroded or lead, replacing it changes everything downstream.

Signs it is time to call

Weak pressure throughout the house, a lead or galvanized service, leaks at the foundation entry, or a municipal lead replacement on the city side are common reasons. A home being renovated with more bathrooms may simply need a larger service.

On the job, step by step

  1. Confirm material at the meter and curb stop location.
  2. Arrange locates and any municipal permit; coordinate with the city for the curb stop.
  3. Install the new line by trench or by trenchless pulling, often three-quarter or one-inch copper or approved plastic.
  4. Seal where the line passes through the wall.
  5. Tie in at the meter, adding a fresh quarter-turn main valve.
  • New main valve installed
  • Foundation sealed
  • Flushed before use

GTA houses and what they change

Toronto and several other municipalities have run programs to replace lead services on the city side and have pressed owners to do their portion in the same season. Check the current terms with your city. Frost depth in the GTA means services sit well below grade, so depth matters for excavation.

Before you pick up the phone

Ask whether the city side will be done too, what size line is proposed, and whether landscaping restoration is included. Call (365) 387-8531.

Common questions

Is my service lead?

Inspect the short length between foundation and meter. Lead reads as soft, matte pewter, and shows shiny metal when gently scratched. A magnet will not stick.
