Condominium Plumbing in Toronto

Yes. We work throughout the City of Toronto, which since amalgamation in 1998 includes North York, Scarborough, Etobicoke, York and East York as well as the old City of Toronto. Most of our completed riser and valve work sits in the downtown core, along Yonge Street and through midtown, but the crews are in North York and Etobicoke buildings on the same week. Our office is at 356 Marlee Ave, so nothing in the city is a long run for an emergency call.

Age alone does not decide it, but it tells you when to start looking. A large share of Toronto's condominium stock went up in the 1970s and 1980s, which puts the original domestic water risers somewhere between forty and fifty-five years old now, and that is the window where pinhole leaks stop being isolated events and start repeating on the same stack. The honest answer comes from evidence rather than a birthday: repair history by stack, the condition of pipe removed during an unrelated repair, and a camera inspection. We would rather open one wall and tell you the pipe has ten years left than sell you a programme you do not need yet.

That is the normal way it is done, and it is most of what we do in Toronto. The work is phased stack by stack rather than floor by floor, so water is off on a handful of suites on their scheduled day and everyone else in the tower is unaffected. Residents stay in their homes for the whole programme. Each suite gets written notice of its date and window, walls are opened, the new pipe is installed and pressure tested, and our own finishing crew closes, sands and paints before the crew leaves that floor.

Because the city pressure that reaches a tall building is more than the lower floors can tolerate. Toronto Water delivers pressure sufficient to push water up the building, which means the suites nearest the ground would see pressure high enough to damage fixtures, hammer the pipework and cause premature failures at flexible connections. A pressure reducing valve station drops the pressure for the lower zones, and the taller the building, the more zones it has. When a PRV drifts or fails, the symptoms arrive as a run of burst supply lines or a sudden noise complaint rather than as an obvious valve problem, which is why the station gets inspected rather than waited on.

Many buildings do need it, and the requirement is annual. The City's cross-connection control programme covers properties where the building's water system could contaminate the municipal supply, and condominiums with irrigation systems, boiler make-up lines, mechanical loops or commercial units at grade generally fall inside it. Testing has to be done by a certified tester and the report filed. We test, repair or rebuild what fails, and retest so the corporation holds a clean certificate rather than an outstanding one.

The mechanical work is often the straightforward part; scheduling around a tower with one service elevator and a single loading dock is the harder problem. We book the elevator and the dock through property management before the programme starts rather than turning up and competing for them, work within the building's noise hours, and sequence suites so the crew moves logically through a stack instead of criss-crossing the building. On downtown sites with restricted street access, material is staged inside on the level where the work is happening.

It depends on the scope, the number of stacks and the state of what we find, and anybody quoting a building-wide number over the phone is guessing. What we can tell you is how we get to a real number: we come and look at the building before we quote it, open representative points where we need to, and price the actual repeating suite types rather than an average. For maintenance work like stack cleaning or a valve exercise programme, the pricing is per building per visit and holds across a contract term.
