What We Repair and Replace

We handle both water supply and sewer lateral systems:

Cracked, offset, or collapsed lines

Tree root intrusions

Slow or backed-up sewer flow

Discoloured or foul-smelling water

Leaking or broken water lines

Old polybutylene or galvanized piping

Lines damaged by frost heave or shifting ground

Poor slope or improper installation

We use proper trenching methods, trenchless options where possible, and only code-approved materials — including copper, PEX, and SDR pipe.

Who’s Responsible for Line Repairs?

Sewer Line: You’re typically responsible from your home to the property line. The city handles beyond that

Water Line: You’re responsible from the water meter or curb stop to your home’s interior.

Frequently Asked Questions

Do I need a full replacement if there’s a leak?

Not always. We inspect the line and recommend repair when possible — but full replacement is better if the pipe is too degraded.

How long will my yard be disrupted?

Repairs usually take 1–2 days. Full replacements take 1-2 days. We restore all excavation areas before we leave.

Can you do trenchless replacement?

Trenchless replacement (pipe bursting) is available in Orillia only, through a trusted partner. We’ll assess your layout and let you know if it’s an option for your property.
