Plumbing in Burlington Condos

Condo plumbing comes with a twist: the pipe behind your wall may belong to you, the corporation or both, and a leak can reach units above and below. Knowing the rules before something goes wrong saves money and friction.

The short answer

In Ontario, each condominium's declaration and bylaws decide which parts of the plumbing are part of your unit and which are common elements. As a general pattern, the fixtures, appliances and supply lines serving only your suite are often the owner's responsibility, while risers, stacks and building systems are the corporation's. The details vary from building to building, so the only reliable answer comes from your own documents and property management.

Key point

Condo plumbing comes with a twist: the pipe behind your wall may belong to you, the corporation or both, and a leak can reach units above and below.

Step by step: before anything happens

  1. Find your shut-off valves. Many suites have isolation valves for the unit inside a closet, behind an access panel or under the kitchen sink. Know where they are and check they turn. Our guide to shut-off valve locations helps.
  2. Read the declaration and the standard unit description. These say what counts as part of your unit for repair and insurance purposes.
  3. Check your insurance. Condo owner policies typically cover improvements and liability, and many owners add coverage for the corporation's deductible, which can be charged back to a unit where a leak began.
  4. Replace risky hoses. Rubber washing machine hoses and old toilet and faucet supply lines are frequent sources of leaks. Braided stainless lines are a cheap upgrade.
  5. Learn the building's rules for contractors: notice, insurance certificates, elevator booking and allowed hours.
Water heaters in suites: some buildings have individual tanks in each unit, often rented or managed under a building program. An old tank in a closet above someone else's ceiling deserves attention before it fails.

Have this ready when you call

  • Which fixture, which floor
  • Whether the main is closed
  • Rough age of the house and heater
  • Any past floods or drain work

When a leak happens

  • Shut off the water to the affected fixture or the suite.
  • Notify property management or the superintendent at once, even if the leak seems small; water travels between floors.
  • If water is coming from above, management can usually access the unit overhead faster than you can.
  • Photograph the damage and keep records for insurance.

First move in a leak

Close the main shut-off, open a low tap to drain pressure, then call (365) 464-5184.

The moment to phone us

Call for anything inside your unit that you are responsible for: a running toilet, a dripping faucet, a slow drain, a failed dishwasher connection. For problems in risers or common drain stacks, management should arrange the repair. Many buildings also require that any plumber working in a suite be approved or at least registered with management first. Our pages on toilet repair, faucet repair and kitchen sink installation cover common condo jobs.

Burlington specifics

Burlington's condo towers cluster along Lakeshore Road downtown, around Maple and near major corridors such as Plains Road and Fairview Street, with newer mid-rise buildings around the GO stations. Older towers from the 1970s and 1980s often have original risers and shared drain stacks, where a kitchen clog on one floor can back up into a unit below. Newer buildings may have individual water metering and suite-level shut-offs that are easier to use.

Shared walls and floors make noise and access practical concerns too. Booking work during the building's permitted hours and protecting hallways and elevators keeps neighbours on side. For a broader view of what to do when pipes fail, see what to do after a burst pipe, and if you are planning a bathroom update, read our bathroom renovation plumbing guide before submitting plans to the board.

Questions we hear

Who pays if my toilet leaks into the unit below?

It depends on the declaration, the cause and the insurance policies involved. Report it to management right away and contact your insurer.

Do I need board approval to replace my kitchen sink?

Usually not for a like-for-like swap, but moving fixtures or altering drains often needs approval. Check with management.

Where is my condo's water shut-off?

Many suites have valves tucked in a utility closet or behind a small hatch by the kitchen or laundry. Management can show you.
