Condo leaks: who fixes what

Condo leaks spread sideways and down. The order you call people in matters as much as the repair itself.

  • Plain steps you can follow at home
  • When to stop and call a plumber
  • Written for North York housing stock
  • Licensed and insured (details on the call)
  • Price agreed before work starts
  • North York and next door

The first five minutes

  1. Shut the suite valves, usually near the water heater, laundry or kitchen sink.
  2. Call the building's concierge or management. They can shut risers and check the suite below.
  3. Photograph the leak and any damage.
  4. Then call a plumber, or the building's contractor if management directs it.

Who owns what

It depends on your condo's declaration and bylaws. In many buildings, pipes and fixtures inside the suite after the suite shut-off are the owner's; risers, stacks and common lines are the corporation's. Read your declaration or ask management.

From the counter

Common condo leak sources

  • Washing machine hoses
  • Dishwasher supply connections
  • Toilet supply lines
  • Water heater tanks in a suite closet
  • Caulking around a tub that lets water into the slab
Insurance: condo owners usually need their own unit policy. Check that it covers damage to suites below and your deductible share.

North York towers

Along Yonge between Sheppard and Finch and around Bayview Village, many towers are now old enough that original suite water heaters and supply lines are reaching the end. Replacing hoses and checking the tank age is a sensible move.

Questions

Who pays for damage to the unit below?

It comes down to where the leak started, what your declaration says and whose policy responds. Report it quickly and keep records.

Am I allowed to bring in my own plumber in a condo?

For work inside the suite, generally yes. Expect the building to ask for notice, an insurance certificate or an elevator booking.
