What to know about Sewer line replacement

Sewer line replacement means taking the old building sewer out of service, the buried lateral that carries all of a home's wastewater to the street, and putting a new continuous pipe in its place. It is the step that comes after repairs stop working: when a camera run shows roots at joint after joint, a pipe that has flattened or collapsed, or a long low section that keeps collecting waste, fixing one spot only moves the next blockage further along the line.

Prices depend on the details of your project. We only publish price ranges when they’re backed by real LokalMatch quote data or reliable sources. Until then, here’s what usually changes the price:

  • Type of problem and how easy it is to find
  • Access to pipes behind walls, under floors or underground
  • Parts and fixtures chosen
  • Age and material of the existing pipes
  • Emergency, evening or weekend service
  • Permits and inspections, where required

How to choose plumbers in Dorval

  • Hire a plumber who is licensed for this work in your province, especially for gas water heaters, sewer lines and new plumbing.
  • Ask whether they charge a flat rate or by the hour, and what the call-out fee covers.
  • For leaks and drain problems, choose someone who explains the cause and doesn't only clear the symptom.
  • Get the scope in writing for larger jobs such as a water heater, sewer repair or re-piping.
  • If it's urgent, ask how soon they can arrive and whether after-hours rates apply.

Questions to ask plumbers before you hire

  • Are you licensed for plumbing work in my province?
  • Do you charge a flat rate or by the hour, and is there a call-out fee?
  • What do you think is causing the problem?
  • Will this work need a permit or an inspection, and who will arrange it?
  • Will you need to open walls, floors or the yard to reach the problem?
  • What warranty do you offer on parts and labour?

Common sewer line replacement questions

Is LokalMatch free for homeowners?

Yes. You never pay LokalMatch to request quotes or talk to pros. Professionals pay a fee to connect with homeowners whose projects fit their business.

How many pros will contact me?

We introduce you to a small number of relevant pros — usually no more than three — so you’re not flooded with calls. If fewer pros are available in your area, we’ll tell you instead of promising quotes we can’t deliver.

Do I have to hire someone?

No. Requesting quotes doesn’t commit you to anything. Compare your options and hire only if someone is the right fit.
