Commercial jobs we take on
- Grease interceptors and restaurant kitchen lines: floor sinks, dish lines and interceptors.
- Office and retail plumbing: washrooms, staff kitchens and small water heaters in plaza units.
- Condo and multi-unit buildings: riser valves, suite shut-offs and shared stack backups.
- Commercial drain jetting: grease, scale and sludge scoured out of larger pipe.
- Backflow prevention testing: annual tests on the devices that protect the city supply.
How commercial work differs from a house call
- Bigger pipe: 4-inch and 6-inch building drains need larger cables or a jetter, not a hand auger.
- Shared systems: one shut-off can cut water to a whole plaza or floor, so isolation is planned first.
- Timing: a kitchen cannot close at lunch, so we book jetting before opening or after close.
- Records: property managers want a written ticket with the location, cause and fix for their files.
Warning signs in a commercial unit
- Grey water pooling in floor sinks beside the dishwasher
- Sewer smell in a washroom or back corridor
- Toilets that flush weakly on one side of the plaza
- Hot water running out partway through the lunch rush
- Water staining on the ceiling tiles below a suite
Markham commercial buildings
Markham has strip plazas along Highway 7, Kennedy Road and Woodbine Avenue, older retail on Main Street Markham and Main Street Unionville, office parks near the 404, and mid-rise condos around Downtown Markham and Markville. Plaza units often share a single sanitary line out the back, so a restaurant clog can back up into the shop next door. Condo towers run copper or PEX risers with isolation valves on each floor that may not have been turned in years. We bring the right valve keys, cables and camera for each of these setups.

We explain what failed and what the fix costs; no cutting starts until you say yes.
