Sewer Lateral Repair in Richmond Hill, ON | OCM Excavation

When sewage starts coming up through a Richmond Hill basement drain, the failure is almost always in the sewer lateral — the underground pipe that runs from your house out to the city sewer main. From the foundation wall to the property line, that pipe belongs to you. Call OCM Excavation at 416-317-3090. We give same-day diagnosis on any Richmond Hill call before 2 PM and walk you through what’s actually broken before you spend a dollar.

Why Richmond Hill Laterals Are Failing Now

Post-war Bayview and Crosby neighbourhoods were built with clay sewer laterals that are now reaching the end of their service life. The older Yonge corridor housing — anything pre-1975 — is the highest-risk zone in Richmond Hill. Newer subdivisions north of Major Mackenzie were built with PVC and don’t fail at the same rate. Four failure modes cover nearly every job:

1. Root intrusion — tree roots find joint cracks in clay pipe and grow inside until flow chokes off. Top cause in Richmond Hill’s established neighbourhoods.
2. Pipe collapse or belly — clay pipe settles over 50 to 80 years. The line sags, holds standing waste, and eventually a section caves in.
3. Offset joints — old hub-and-spigot clay joints shift over decades. Debris catches at the offset and a partial blockage becomes a full one.
4. Wipe and grease blockage — so-called flushable wipes are not flushable. They snag on any offset or root and finish the job.

Camera Inspection First

No camera inspection, no honest quote. We run a video unit through the cleanout for $350-$600. The footage shows the failure location, depth, pipe material, and whether you have a single bad spot or a line that needs full replacement. Book the inspection at 416-317-3090.

Repair Options in Richmond Hill

• Spot repair — $4,500 to $8,000. Excavate to the failed section, usually 6 to 10 feet deep, cut out the bad clay, splice PVC, backfill. Right answer for one isolated failure on an otherwise sound line.
• Full lateral replacement — $8,000 to $18,000. Open trench from the house to the Richmond Hill property line, full PVC replacement. Required when the pipe fails in multiple spots, or when the line is over 60 years old and a spot repair just buys you months.
• Trenchless pipe bursting — $6,000 to $12,000. Hydraulic burster pulls a new PVC pipe through the old clay using two small pits. Less yard disruption, faster turnaround. Only works on certain pipe configurations — the camera report tells us.

Permits and City Coordination

Every Richmond Hill sewer lateral job needs a sewer connection permit and an Ontario One Call locate before we dig. We handle both. Most jobs require connecting to an existing cleanout or installing a new one near the property line. We don’t quote specific bylaw numbers — those shift — but we coordinate directly with the Richmond Hill inspector and pull every permit on your behalf.

What Insurance Actually Covers

This is the part most Richmond Hill homeowners get wrong. A home policy with a sewer backup rider will usually cover the damage inside the house — flooring, drywall, drywall, contents. It will not cover the sewer line repair itself. The excavation and pipe work is on you. We provide a fully itemized invoice in case your adjuster will consider partial coverage.

Timing and Equipment

Any Richmond Hill call before 2 PM gets same-day diagnosis. Repair start is usually next business day, or 1 to 3 days out depending on permit timing. Active basement backup gets priority dispatch — we move it ahead of everything else. We bring a Yanmar SV40 mini-excavator, our own camera unit, a plate compactor for backfill, and rent a hydraulic burster when the trenchless option is viable. Phone 416-317-3090 to start.

FAQ

Is the broken pipe my responsibility or Richmond Hill’s?

If the failure is anywhere between your foundation wall and the property line, it’s your pipe. From the property line out to the sewer main under the road, that’s the Town of Richmond Hill. The camera footage shows depth and distance from the cleanout, so you see exactly where the failure sits.

My drain cleaner snaked it and it’s clear — am I done?

Maybe for a few months. If the underlying pipe is cracked clay with root intrusion, the roots regrow and you’re backed up again by the next season. Snaking buys time. A camera tells you whether you actually need a repair or whether routine maintenance is enough.

How long will the work take?

A spot repair is typically a single day of excavation and pipe work. Full lateral replacement runs 2 to 4 days depending on length, depth, and whether driveway sections need to come up. Trenchless bursting is usually 1 to 2 days because there’s no open trench.

Will the new pipe last?

PVC sewer lateral is rated for 80-plus years. Solvent-welded joints mean tree roots have nothing to invade. A proper PVC replacement is a one-generation fix and you should not see this issue again in your lifetime.
