Emergency Excavation in Toronto, ON | OCM Excavation

Call OCM at 416-317-3090 now if you have sewage backing up into your basement, a sinkhole opening in your yard, or water flooding from a broken line between the street and your house. We dispatch a 3-person crew with a Yanmar SV40 mini-excavator to most Toronto addresses within one to two hours of your call. Here is what to expect, what it costs, and what you should do in the next ten minutes while we are on our way.

What Emergency Excavation Actually Covers in Toronto

Toronto has the oldest sewer infrastructure in the GTA. We still dig up clay pipes that were installed before the Second World War, and root intrusion, joint failure, and full collapse are everyday calls for us. Most of our emergency Toronto dispatches fall into one of these categories:

• Sewer line collapse: Raw sewage backing up through basement floor drains. Almost always a cracked or collapsed clay lateral between the house and the city main.
• Water main break: Yard flooding, low pressure inside, water bubbling up from the lawn or driveway. The lateral from the city shutoff to your house is your responsibility, and it usually fails at the connection or at a frost-heaved joint.
• Sinkhole formation: A depression opening in the yard or driveway. In Toronto this is almost always a broken sewer pipe washing soil away underneath. It does not get better on its own and the hole accelerates fast.
• Foundation crack with active water intrusion: Water pouring into the basement during heavy rain. Often a failed weeping tile and a hairline crack that opens under hydraulic pressure.
• Construction-adjacent collapse: A neighbour’s dig or a city utility cut that has undermined your footing. We shore, excavate, and stabilize.

Response Time — What We Honestly Commit To

For calls received before 2 PM on a weekday, we get a crew on-site the same day for roughly 90% of emergency dispatches inside Toronto. Calls after 2 PM or overnight are scheduled for first thing the next morning unless the situation is actively destroying property — in which case we mobilize a weekend or after-hours crew at premium rates. Our equipment yard is close to the 401 corridor, and the SV40 can be loaded and rolling in under thirty minutes once we confirm the address.

What Emergency Pricing Looks Like

Emergency work in Toronto does not follow regular pricing because permits need expediting, crews work overtime, and we cannot stage materials in advance. Plan for an emergency response fee in the range of $1,500 to $5,000, plus $200 to $350 per hour of crew time, plus materials and permit costs. A straightforward sewer lateral replacement on a Toronto lot typically lands between $8,000 and $22,000 depending on depth, length of run, and whether we have to break and restore a concrete driveway or city sidewalk. You will get an itemized invoice suitable for an insurance claim.

What You Should Do Before Our Crew Arrives

• Call OCM at 416-317-3090 and stay on the line — we will walk you through the immediate steps.
• If it is a water main break, shut off the water at the main valve where the line enters your basement.
• If it is a sinkhole or a suspected sewer collapse, call Toronto 311 so the city can dispatch a crew for the street-side portion of the lateral.
• Take photos and short video clips of the damage from multiple angles. Your insurer will want them.
• Move valuables and electronics off the basement floor. Do not wade through sewage water.

The Insurance Reality in Toronto

Most Toronto homeowner policies cover sewer backup only if you carry the specific rider, and the limit is often capped low. A cracked or collapsed sewer lateral is typically not covered as a structural repair. Sinkhole subsidence coverage is a rare add-on. We do not bill insurance directly, but we provide a detailed itemized invoice with photos, measurements, and material specs so you can submit a clean claim. Call your broker as soon as the situation is stable.

FAQ — Emergency Excavation in Toronto

How fast can you actually get to my Toronto address?

One to two hours for dispatch within the old City of Toronto, North York, Etobicoke, Scarborough, and East York for daytime calls. After-hours dispatches are scheduled for next morning unless property is actively being destroyed, in which case we mobilize at premium rates.

Do I have to call 311 myself, or do you handle it?

You call 311. The city only takes the report from the property owner or occupant, and they will not dispatch their crew for the street-side portion of the lateral on a contractor’s call. We coordinate with their crew once they arrive.

Will my insurance cover the excavation?

Probably not the structural repair itself. Sewer backup damage to finished basements is often covered if you carry the rider. The dig and pipe replacement are usually owner-paid. We provide claim-ready paperwork to give you the best chance of partial reimbursement.

Can you dig in winter?

Yes. Toronto frost depth runs around four feet, and we excavate year-round with frost rippers and heated enclosures when needed. Winter dig costs more because of slower production and frozen-ground breaking, but emergencies do not wait for spring.

What if the problem is on city property?

If the failure is on the city side of the property line, the City of Toronto repairs it on their dime. We help you identify the failure point and document it. From the property line into your house is your responsibility.
