Office and retail plumbing in Markham
Staff washrooms, customer restrooms, kitchenettes and small water heaters keep a plaza unit open. We repair flush valves, sensor faucets, clogged urinals and leaking supply lines, and keep your taps dry for the shortest stretch possible.
- Flushometers and touchless taps rebuilt
- Washroom clogs cleared without closing the unit
- Small tank and point-of-use heaters swapped
- Isolation valves added so one leak never shuts the floor
- Licensed plumbers (details on request)
- Price agreed before work
- Call-only, no forms
- Tested before we leave
Common office and retail calls
- Toilets and urinals that keep running, flush twice or barely flush
- Sensor faucets dripping or failing to turn on
- Staff kitchen sinks clogged with coffee grounds
- Small electric heaters leaking in a ceiling or closet
- Water stains on drop-ceiling tiles from a hidden supply leak
How the repair runs
- Talk to the manager about hours and which fixtures can be closed.
- Shut the nearest isolation valve, not the building main, where one exists.
- Rebuild or replace the flush valve, cartridge or sensor module.
- Clear any drain with a closet auger or cable sized to the line.
- Restore water, test each fixture and check the ceiling below.
Signs to call sooner
- A meter or water bill rising while staff numbers stay the same
- A washroom that smells of sewer after weekends
- A ceiling tile sagging under a washroom or kitchenette
What is included
- Fixture parts matched to the brand on the wall where possible
- A written ticket listing what was rebuilt or replaced
- Notes on any fixtures that will need attention soon
Markham plaza plumbing
Markham's plazas and office parks were mostly built from the 1980s on, so their washrooms now carry thirty-year-old flush valves, stops that seize and shared drain lines between units. Older retail on Main Street Markham and Main Street Unionville sits in heritage buildings where cast iron and galvanized pipe can still turn up above the ceiling. If the building has a property manager, we coordinate shut-offs with them before we start.
