Emergency Plumbing Help in Oshawa
This page explains how to tell a true emergency from an urgent repair, what you can safely do in the first few minutes, and how to submit a request for plumbing help. Submitting a request does not guarantee a response or dispatch, so if you are in danger, call 911 first.
Common symptoms
- Water spraying or pouring from a pipe, fitting or appliance hose
- Sewage or grey water coming up through a floor drain, toilet or tub
- Water near your electrical panel, outlets or appliances
- Water heater leaking from the tank body rather than a fitting
- No water anywhere in the house with no known city work nearby
- A smell of natural gas near a gas water heater or appliance
Common causes
- Frozen supply lines that crack as they thaw, often in exterior walls or garages
- Corroded tank bottoms on older water heaters
- Failed washing machine or dishwasher supply hoses
- Tree roots, grease or a collapsed section blocking the main sewer line
- Power outages or pump failures during heavy rain
Safe steps you can take now
- Shut off the main water valve, usually where the water line enters the basement near the meter.
- If water is near outlets or the panel, do not walk through it. Keep away and call your utility or 911 if you cannot safely reach the breaker.
- Turn off the power or gas supply to a leaking water heater using its own controls.
- Open a low faucet to drain remaining pressure from the lines.
- Move valuables off the floor and photograph the damage for insurance.
- Stop using fixtures if a drain is backing up — every flush adds more water.
When to call a qualified plumber
- You cannot stop the water with a fixture valve or the main shut-off
- Sewage is entering the living space
- Water has reached electrical equipment
- You smell gas — leave the home and call Enbridge Gas or 911 from outside
Typical repair options
Temporary isolation
Capping or clamping a damaged pipe so the rest of the house can have water while a permanent repair is planned.
Section replacement
Cutting out a split or corroded section of pipe and replacing it with new copper or PEX.
Drain clearing
Using a cable machine or water jetter to open a blocked main drain, often followed by a camera inspection.
Equipment replacement
Replacing a failed water heater or sump pump when repair isn't practical.
What affects the cost
Prices vary from job to job, so we don't publish fixed rates. These are the factors that usually make the biggest difference. Ask for quotes in Canadian dollars and confirm whether HST is included.
- Time of day and whether the visit is after regular business hours
- How easy it is to reach the damaged pipe (open basement ceiling vs finished walls)
- Whether parts such as a water heater or pump need to be replaced
- Follow-up work such as drywall repair or drying, which is usually separate from plumbing

Oshawa context
Oshawa sees regular deep-freeze periods in winter, and pipes running through exterior walls, crawl spaces and attached garages are most at risk. Water and sewer service to Oshawa homes is managed by the Region of Durham, so if the whole street has no water, check for regional notices before assuming a problem in your house.
Frequently asked questions
Is a dripping faucet an emergency?
No. A drip wastes water but rarely causes damage. Shut off the fixture valve under the sink if it bothers you and request a regular repair.
Where is my main water shut-off?
In most Oshawa houses it is in the basement where the water line comes through the foundation wall, close to the water meter. Find it and test it before you need it.
Will my home insurance cover water damage?
Coverage varies widely, especially for sewer backup and overland flooding. Check your policy and call your insurer early; take photos before cleaning up.
Does submitting a request guarantee someone will come right away?
No. Availability isn't guaranteed and we can't promise a response time. For danger to people, call 911. For gas smells, leave and call Enbridge Gas from outside.
Should I call the Region of Durham or a plumber?
If the problem is on the city side — for example no water across the street, or a backup affecting multiple homes — contact the Region. Problems inside your property line are generally the homeowner's responsibility.
