Commercial drains work harder than residential ones, and they fail at the worst possible times — mid-service in a restaurant, during business hours in a clinic, on a delivery day in a plaza. Scheduled drain and sewer cleaning keeps your lines flowing and turns emergencies into routine maintenance.
Markham's commercial corridors along Highway 7, Woodbine Avenue and Kennedy Road are full of restaurants, food courts and mixed-use plazas, and grease is the constant theme. Even with a properly maintained grease trap, lines narrow over time. We clean commercial drains and sewers on schedules that match your usage, at hours that don't disrupt your business.
Drain & Sewer Cleaning Around Markham
Markham's restaurant corridors along Highway 7, Kennedy Road and Woodbine Avenue keep us busy with grease line cleaning. Even well-maintained grease traps let some grease through, and lines narrow gradually until a Friday dinner rush finds the limit. Scheduled jetting outside business hours is how our commercial clients avoid that call.
Plazas and multi-unit buildings have shared lines where one tenant's habits affect everyone. We work with property managers on building-wide cleaning schedules with documentation for each visit — useful when lease disputes about drain responsibility come up.
Signs You Need Drain & Sewer Cleaning
Book a cleaning before these signs turn into a shutdown:
- Slow floor drains in the kitchen or prep area. Floor drains handle the heaviest loads in a commercial kitchen. When they slow down, the line is narrowing.
- Recurring clogs in the same fixtures. A sink or drain that clogs every few weeks is telling you the line downstream needs a proper cleaning, not another quick snake.
- Odours from drains. Grease and organic buildup in the line produce smells that customers notice before staff do.
- Gurgling between fixtures. Air displacement between fixtures means a partial blockage is forming in a shared line.
- It's been more than a year since the last cleaning. For food service businesses, annual or semi-annual cleaning is standard preventive maintenance, not an extravagance.
- A backup has already happened once. One backup without follow-up cleaning and inspection almost guarantees a second.
How We Do It
- 1
Assess your lines and usage
We review your fixtures, grease trap setup and history of problems to plan the right cleaning approach.
- 2
Camera inspection
For first-time service or problem lines, we inspect with a camera to see buildup levels, pipe condition and any damage.
- 3
Clean with the right method
Hydro jetting is the standard for commercial grease lines — it scours the full pipe wall rather than poking a hole through. Mechanical cleaning handles roots and scale where present.
- 4
Work around your hours
We schedule before opening, after closing or on your quietest day, so the work never costs you customers.
- 5
Verify and document
A post-cleaning camera check confirms the result, and you get documentation useful for property managers, franchisors and health inspections.
- 6
Set a maintenance schedule
Based on what we find, we recommend a cleaning interval that matches your actual usage — and we remind you when it's due.

Drain & Sewer Cleaning FAQs
How often should a restaurant's drains be cleaned?
Most food service businesses benefit from hydro jetting every six to twelve months, depending on volume and menu. High-grease kitchens may need quarterly service. We'll recommend an interval based on what the camera shows, not a generic schedule.
Can you work outside business hours?
Yes — that's how most of our commercial work is scheduled. Early mornings, evenings and closed days are all available, including for planned maintenance.
Do you service multi-unit plazas and shared lines?
Yes. We work with property managers on shared stack and lateral cleaning, and can coordinate access across units with proper notice and documentation.
What's the difference between snaking and jetting for a commercial line?
Snaking restores flow through a blockage but leaves most of the grease on the pipe wall, so the clog returns. Jetting removes the buildup itself. For commercial grease lines, jetting is almost always the right tool.
Do you provide service records for health inspections?
Yes. Every visit is documented, and camera footage is available for your records. Many franchisors and property managers require exactly this kind of maintenance documentation.
