- We replace lead lines with safe, durable copper piping.
Public vs Private Portion
Your water service line has two parts: the public portion, from the city main to your property line, and the private portion, from the property line into your home. The City is responsible for the public portion, and you are responsible for the private portion. When the City replaces its section, the private side must be replaced too so you are not left with a partial lead line.
Your Options and the Grant
You can wait for City crews and have them replace the private portion at your expense, or you can hire your own licensed plumber ahead of time. A RénoPlex grant of $1,200 is available toward replacing your lead service entry, though you must apply for at least $3,000 in grants to qualify. We help you plan the work so it lines up with the program.

Can I use my own plumber instead of waiting for the City?
Yes. You can hire a licensed plumber to replace the private portion before City crews arrive, which often gives you more control over timing and cost.
