Lead & Water Service Replacement for Older Ottawa Homes

Many Ottawa homes built before 1958 still get their water through the original pipe. We'll help you find out what you have, plan a replacement route that protects your porch and landscaping, and follow the City's steps so you can claim what you're entitled to.

Do you have a lead water service?

According to the City of Ottawa, homes built before 1958 are the ones most likely to have a lead service pipe, about 15% of Ottawa homes. Lead was used until the 1950s. A newer home connected to an older watermain can also have a lead public portion.

A quick check: find where the water pipe comes through your basement floor or wall, just before the meter. Gently scratch it with a key or coin.

  • Lead is dull grey, soft, and scratches easily to a shiny silver
  • Copper is reddish-brown, like a penny
  • Galvanized steel is grey and hard, and a magnet sticks to it

Not sure? We'll look at it with you.

Who owns which part

  • You own the private portion: from the house to the shut-off valve near the property line.
  • The City owns the public portion: from the shut-off valve to the watermain under the street.

The City runs a Lead Pipe Replacement Program with two routes. Under a full replacement, the City coordinates replacing both sides together, and you can spread your share over five or ten years on your property tax bill. Under a partial replacement, where the City's side is already copper, you replace the private side yourself and can claim a rebate of up to $1,000, which the City describes as about 20% of a typical private-side replacement.

The City's program has a strict order of steps: permit, utility locates, booking the City's "Connect at Post" two business days ahead, a water turn-off through 3-1-1, inspection, then the rebate application. We work through each one with you. Details: City of Ottawa Lead Pipe Replacement Program.

Your porch, walkway and garden matter

In the Glebe, Old Ottawa East and other older neighbourhoods, the water line often runs under a stone porch, steps, mature trees or a front garden that took decades to grow. A water service quote should explain the route, not just the price.

Before we quote, we look at:

  • Where the line enters the house, and whether we can come in beside the porch or under a basement window instead of through it
  • Whether a trenchless method can pull or bore the new line with less surface digging
  • What has to be lifted and set aside (interlock, flagstone, sod) and who restores what
  • Where the shut-off and the City's side are, so both ends line up

Every property is different, and only a site assessment can confirm what's possible. But you should never get a quote that doesn't tell you what happens to your front yard.

Getting a second opinion

If you've been told you need a new water line, or you're comparing two very different quotes, we're happy to look. Two quotes can differ because one includes restoration and the other doesn't, or because one plans to dig through the porch and the other goes around it. Ask both contractors the same questions, and compare like with like.

Neighbours on the same street

Lead services often run along a whole block of homes built in the same years. When neighbours replace around the same time, the site set-up, locates and scheduling can be shared. Ask us about coordinating with the house next door.

Other water line problems we fix

Not every water service is lead. We also replace aging copper and galvanized lines with low pressure or leaks, lines that froze and split, and old main shut-off valves that won't close.

What customers say about this work

★★★★★
“Mike was recommended by a friend for a tricky job on our very old water main/meter (which had been ridiculously encased in concrete), and did a great job. Melissa was easy to deal with to make all the arrangements.”

Questions Ottawa homeowners ask us

How do I know if my Ottawa home has a lead water pipe?
Homes built before 1958 are most likely to have one. Scratch the pipe just before the water meter: lead is dull grey, soft and scratches to shiny silver. Copper is reddish-brown. We can confirm it on a visit.
Who pays to replace a lead water service in Ottawa?
You pay for the private side, from the house to the shut-off valve. The City is responsible for the public side. Under the City's full program you can spread your share over five or ten years on your tax bill. Under the partial program you can claim a rebate of up to $1,000 for the private side.
Will you have to dig up my porch?
Not if there's a better route. We look first at coming in beside the porch or through the foundation under a window, and at trenchless options. The route and the restoration are written into the quote.
How long will we be without water?
Usually only part of one day, while the old line is disconnected and the new one connected. The City has to turn the water off at the curb, which is booked through 3-1-1 a business day ahead.
Is there a rebate for replacing a lead pipe?
Yes. If the City's side is already not lead, you can apply for up to $1,000 toward the private-side replacement after the work, the permit and the inspection are complete. The City has specific steps and documents, and we help you through them.
Should I get a second opinion on a water line quote?
For a job this size, yes. Compare the route, what's included in restoration, who handles the City's steps, and the warranty, not just the price.
