A blocked drain behind a restaurant kitchen or a slow floor drain in a plaza washroom can shut down operations fast. We clean drain and sewer lines for restaurants, retail units, offices, and multi-unit buildings across Scarborough, working with owners and managers to get lines flowing again with as little interruption as possible.
Commercial drain systems see heavier, more varied use than a typical home, from grease-laden kitchen wastewater to high-volume washroom traffic, and the pipe runs are often longer and harder to access. We bring cameras, cabling, and jetting tools suited to larger diameter lines and schedule work around your opening hours whenever possible.
From the strip plazas along Eglinton and Kennedy to the office buildings near Lawrence and Victoria Park, we've cleared everything from grease-clogged kitchen lines to root-choked sewer laterals feeding older commercial blocks in Scarborough.
Signs You Need Drain & Sewer Cleaning
Watch for these signs that a commercial drain or sewer line needs attention:
Slow-draining floor drains
Water that lingers in floor drains or mop sinks after use often means buildup is narrowing the line further downstream.
Gurgling from fixtures
Gurgling sounds from sinks or toilets when other fixtures run can point to a partial blockage in a shared drain line.
Recurring backups in the same spot
If the same drain keeps backing up despite regular cleaning, the issue is likely further down the line rather than at the fixture itself.
Sewage odour near floor drains
A persistent smell near floor drains or grease interceptors can indicate trapped waste or a venting problem.
Water pooling around a drain
Standing water around a floor drain after cleaning or mopping suggests the drain isn't clearing at the rate it should.
Multiple units affected at once
In a plaza or multi-tenant building, several units backing up together usually points to a shared sewer line issue rather than an isolated clog.
Frequent need for plunging or chemical cleaners
Needing to clear the same drain repeatedly with store-bought products is a sign the blockage hasn't actually cleared.
How We Do It
Our approach to commercial drain and sewer cleaning:
Step 1: Discussion with staff or management
We start by asking which drains are affected and how often, since this helps narrow down whether the issue is local to one fixture or shared across the line.
Step 2: Camera inspection
We run a camera through the line where practical to identify the type and location of the blockage before choosing a clearing method.
Step 3: Cabling or jetting
Depending on what the camera shows, we clear the line with cabling equipment or high-pressure jetting sized for commercial diameter pipe.
Step 4: Flow testing
Once the line is clear, we run water from multiple fixtures to confirm drainage has returned to normal across the affected area.
Step 5: Scheduling around your hours
Where the work allows, we plan noisier or longer jobs for slower periods or after closing to reduce disruption to customers and staff.
Step 6: Recommendations for prevention
We point out contributing factors, such as grease buildup or root intrusion, and discuss a cleaning interval that suits your volume of use.
Serving Scarborough's commercial corridors
Plazas along Kingston Road, Eglinton Avenue, and Kennedy Road often sit on older sewer laterals shared by several tenants, so a blockage in one unit's line can back up into a neighbouring business. We look at the wider layout of the property, not just the affected fixture, when cleaning a commercial line.
In older commercial strips near Birch Cliff and Wexford, tree roots are a recurring cause of slow-draining laterals where clay pipe is still in place. We check for root intrusion during camera inspections so owners know whether a cleaning will hold or the line needs more frequent attention.
Why Choose Scarborough Plumbing
Equipment for larger lines
Commercial drain and sewer lines are typically larger than residential ones, and we bring cabling and jetting equipment matched to that scale.
Minimal disruption to operations
We work with owners and managers to schedule cleaning at times that limit the impact on customers, staff, and deliveries.
Experience across property types
We've worked on drain systems in restaurants, offices, retail units, and multi-unit residential buildings throughout Scarborough.
Clear reporting
Where a camera inspection is done, we explain what we found so property managers can plan any longer-term line repairs if needed.
Drain & Sewer Cleaning FAQs
How often should a commercial kitchen drain be cleaned?
This depends on the type and volume of food prep, but restaurants generally benefit from a more frequent cleaning schedule than a typical retail unit due to grease buildup.
Can you work outside our business hours?
Where the scope of work allows, we try to schedule cleaning during slower periods or after closing to minimize disruption.
Do you clean lines shared between multiple units?
Yes, we can inspect and clean shared sewer laterals serving several tenants in a plaza or multi-unit building.
Will a camera inspection show why the drain keeps backing up?
In most cases yes, a camera inspection can reveal grease buildup, root intrusion, or structural issues in the pipe causing repeat backups.
What's the difference between cabling and jetting?
Cabling mechanically breaks up and pulls back a blockage, while jetting uses high-pressure water to scour the inside of the pipe; we choose the method based on what the camera inspection shows.
