Water Line Replacement FAQ

What is trenchless water line replacement?

Trenchless water line replacement is a method of installing a new water service line without digging a full trench across your yard, driveway, or landscaping. The new pipe is installed through small access points, reducing disruption and restoration work.

When does a water line need to be replaced instead of repaired?

A full replacement is usually recommended when the pipe is heavily corroded, leaking in multiple areas, undersized, or made from outdated materials like galvanized steel or polybutylene.

How do I know if my water line is failing?

Common signs include low water pressure, discoloured water, unexplained wet spots in the yard, rising water bills, or water entering the basement near the foundation.

Is trenchless water line replacement better than excavation?

In many cases, yes. Trenchless methods avoid damaging driveways, concrete, trees, and landscaping, often resulting in faster completion and lower overall restoration costs compared to open excavation.

How long does trenchless water line replacement take?

Most trenchless water line replacements can be completed in one day, depending on pipe length, soil conditions, and site access.

Will my water be shut off during the work?

Yes, water service is temporarily shut off during the replacement, but it is typically restored the same day once the new line is installed and tested.
