Commercial Drain Cleaning and Camera Inspection
Home › Commercial Plumbing › Commercial Drain Cleaning and Camera Inspection

Commercial drains work harder than any residential system. Restaurant kitchens send grease, food waste and hot water down the same lines every day, and multi-unit buildings put dozens of washrooms on one shared stack. Plumber On Demand provides commercial drain cleaning and drain camera inspection across Ontario, so food service and high-traffic properties can stay open and keep their drains flowing.
Commercial drain problems we clear
- Grease-heavy kitchen lines from fryers, prep sinks, dish pits and floor drains
- Multi-unit and shared line backups in plazas, apartment buildings and office towers
- Slow or gurgling floor drains in kitchens, mechanical rooms and parking areas
- Washroom backups in public and staff washrooms with heavy daily use
- Main sewer line blockages from roots, debris, grease build-up or damaged pipe
- Recurring clogs that come back weeks after a quick fix
Snaking, flushing and clearing
We match the method to the line. Simple blockages near a fixture are usually cleared with a drain snake. Long kitchen runs and grease-coated lines often need heavier cleaning to remove the build-up from the pipe walls, not just punch a hole through the clog. The goal is to restore full flow so the same drain is not backing up again in a week.
Drain camera inspections
When a drain keeps clogging or the cause is not obvious at the fixture, a drain camera inspection shows what is actually happening inside the line. We run a camera through the pipe to look for grease build-up, roots, sagging sections, cracks, offsets and foreign objects. You see the footage, we explain what it means, and you get a clear recommendation, whether that is regular cleaning, a spot repair or a larger line replacement.
Camera inspections are also useful before buying or leasing a commercial property, before a kitchen renovation, or when a new tenant reports problems with an older line.
Restaurant and food service drains
Kitchens are the most common source of commercial drain calls. Fats, oils and grease cool and harden inside the pipe, then catch food particles until the line closes up. Many Ontario municipalities also expect food service businesses to manage grease properly through interceptors and regular maintenance. We can clear kitchen lines, check the condition of the piping around your grease interceptor, and set up a cleaning schedule that fits your volume, so a backup does not hit on your busiest night.
Preventive drain maintenance
For restaurants, plazas and multi-unit buildings, scheduled drain maintenance usually costs less than emergency calls and lost business. We can inspect and clean high-risk lines on a regular schedule, keep notes on line condition over time, and flag problems early.

Commercial Drain Cleaning and Camera Inspection FAQs
How often should a restaurant have its drains cleaned?
It depends on your menu, volume and how grease is managed. Busy kitchens that fry often may need line cleaning every few months, while lighter operations can go longer. A camera inspection is the best way to set a schedule based on how fast build-up returns.
Can you clean drains outside our business hours?
Yes. We can often schedule commercial drain cleaning before opening, after closing or during slower periods so your kitchen and washrooms are not out of service during peak times.
What does a drain camera inspection show?
A camera inspection shows the inside of the drain line, including grease build-up, roots, cracks, sags, offsets and objects stuck in the pipe. It tells you whether the line needs cleaning, a repair or replacement.
Do you handle backups in multi-unit buildings?
Yes. We clear shared lines and stacks in apartment buildings, plazas and office buildings, and we can help identify which units or fixtures are contributing to repeat backups.
