Commercial plumbing we fix today
Need something else at home? We also handle faucet installs, supply line and shut-off replacements, and garbage disposals. Ask when you call.
Drain Cleaning
Slow sinks, floor drains, or main lines. We clear commercial clogs safely and confirm flow so the problem does not come right back.
SEWER BACKUP RESPONSE
Backups in basements, cleanouts, or floor drains. We identify the source, clear the line, and recommend next steps if roots or pipe issues are found.
WASHROOM PLUMBING
Running toilets, weak flush, clogged urinals, broken flush valves, and leaking shutoffs. We restore service fast and reduce repeat calls.

Leak Repair
Active leaks in ceilings, walls, kitchens, and washrooms. We isolate the right zone, stop damage, and repair properly.
WATER HEATER SERVICE
No hot water for staff or customers. Diagnostics and repair for commercial tanks and tankless units, plus replacement when it is the smarter move.
Camera Inspections
Need answers for recurring clogs or drain odours. Camera inspections pinpoint breaks, bellies, roots, and bad connections so you fix the cause.
Industries we commonly help
We assess the line, clear clogs with cable equipment or hydro jetting when appropriate, then confirm flow and condition with a camera when needed. If we find roots, a belly, or damaged pipe, we explain repair options. You get a written scope and price range before work starts.

Get us on site faster
A few details upfront helps us bring the right parts, plan access, and cut downtime.
What is affected
Tell us what is not working: one fixture, one washroom, one unit, or the whole building. Mention any floor drains backing up or multiple slow drains.
Where is the shutoff
If safe, locate the closest shutoff (fixture valve, washroom isolation, or building main). If you cannot find it, we will handle it on arrival.
Any active water or damage
Let us know if water is spreading, dripping through ceilings, or near electrical rooms. If water is actively flowing, contain it and call right away.
Access and timing
Confirm who can grant access, where to park, and if there are locked mechanical rooms or after hours entry steps.
Photos help
If you can, take a quick photo of the fixture, the leak area, or the floor drain. It helps us prep parts and tools before we arrive.
Safety note
If you smell gas or suspect a gas issue, leave the area and call your gas utility from a safe location, then call us to coordinate next steps.
