Kitchen Stack Cleaning for Toronto Condominiums
In a condo or apartment building, every kitchen on a vertical line drains into the same pipe: the kitchen stack. Grease, oil, soap and food waste from dozens of suites cool and stick to the inside of that pipe until the opening is a fraction of its original size. When it finally blocks, the water from every kitchen above has nowhere to go but up through the sinks on the lowest floors. A blocked kitchen stack is never a one-suite problem.
POM Plumbing provides kitchen stack cleaning and power flushing for condominium corporations, property managers and rental buildings across Toronto and the GTA. We clean the full height of each stack with high-pressure jetting, verify the result with a recorded camera inspection, and give the board a written condition report and a recommended cleaning interval for every stack.

Signs Your Building's Kitchen Stacks Need Cleaning
01
Gurgling Kitchen Sinks
Air being pushed through a narrowed stack makes sinks gurgle when neighbours run water.
02
Slow Sinks on Lower Floors
The lowest suites on a line are the first to drain slowly as the stack narrows.
03
Water Rising in a Lower Suite
Dirty water coming up through a sink when nobody in the suite is using water is a classic stack blockage.
04
Repeat Calls to the Same Stack
Snaking one suite's line does not fix a stack that is narrowed for its full height.
05
Sewage Smell in Kitchens
Rotting grease and poor venting push odours into suites and corridors.
06
No Cleaning History
If your building has no record of stack cleaning in the last three years, it is overdue for an inspection.
What Is Happening Inside the Pipe
Kitchen stack build-up is a mix of fats, oils and grease (FOG), soap residue that reacts with grease to form hard deposits, food particles and, in older buildings, scale on cast iron walls. Each layer traps the next. Jetting removes this build-up back to the pipe wall without damaging the pipe.
| Method | What it does | Used for |
|---|---|---|
| Snaking / cabling | Punches a hole through a blockage | Emergency relief in one suite line |
| High-pressure jetting | Scours grease from the full pipe wall | Full-height stack cleaning |
| Rotating descaling nozzle | Removes hard grease and cast iron scale | Older and heavily built-up stacks |
| Camera inspection | Records pipe condition before and after | Verification and condition reports |
| Lining or replacement | Restores a damaged stack | Cracked or badly corroded pipe |

How We Clean a Kitchen Stack
We run stack cleaning as a planned program, coordinated with management and residents.
- Review and plan. We review drawings, history and complaint logs, and agree a schedule with management.
- Notify residents. Every suite on a stack gets written notice of the date, time window and what to clear under the sink.
- Open and jet. Access points are protected; we jet the full height of the stack and the horizontal line to the main.
- Flush and camera. Debris is removed at the base and the cleaned stack is recorded on camera.
- Reinstate and report. Access points are closed and tested, and the board receives a report per stack.
What Residents Need to Do
- Clear the cabinet under the kitchen sink on the scheduled day
- Do not use the kitchen sink or dishwasher during the work window
- Remove the strainer if asked and leave the area accessible
- Report any water rising in the sink to the crew or concierge immediately
- Run hot water for a few minutes after the work is complete
- Never pour grease, oil or coffee grounds down the sink

How Often Should Kitchen Stacks Be Cleaned?
Most Toronto condo buildings clean kitchen stacks every 12 to 24 months. Buildings with a history of backups, large suites, many garbage disposals or heavy scale in cast iron should be on an annual cycle, while small buildings with a clean camera history may stretch to 36 months. The camera report after each cleaning tells us how quickly each stack is building up, so the interval can be set stack by stack.
A Condition Record, Not Only a Cleaned Pipe
Cleaning is maintenance; replacement is capital. Jetting restores flow in a sound stack, but it cannot fix pipe that is cracked, badly corroded or has failed joints. When the camera shows damage, we document it and recommend spot repair, lining or replacement so the board can plan it in the reserve fund. Because we also replace stacks and risers, our recommendations are based on what the camera shows, not on what we want to sell.

Kitchen Stack Cleaning FAQ
-
What is kitchen stack cleaning?
It is the cleaning of the shared vertical drain pipe that serves kitchens on the same line in a condo or apartment building, using high-pressure jetting to remove grease and build-up from the full height of the pipe.
-
Why is my kitchen sink slow when my neighbours’ sinks are fine?
If only your sink is slow, the blockage is probably in your suite line. If several suites low on the same line are slow, the shared stack is likely narrowed.
-
Why does water come up in my sink when my neighbour runs theirs?
The stack below your suite is blocked or narrowed, so water from suites above backs up into the lowest open drain, often your kitchen sink.
-
Can I use a liquid drain cleaner in my condo sink?
We do not recommend it. Chemicals rarely clear a stack blockage, can damage older pipes and create a hazard for plumbers working on the line.
-
How often should a condo clean its kitchen stacks?
Most buildings clean every 12 to 24 months. Buildings with past backups should be on an annual cycle, and buildings with a clean history may stretch to 36 months.
-
Do I need to be home for kitchen stack cleaning?
Usually not. Most work is done from the roof and clean-outs. You will be asked not to use the kitchen sink during the scheduled window.
-
How long will my sink be out of use?
Usually only during the work window on your stack, typically part of one day.
-
Do you need access to every suite?
No. Suite access is only needed where a stack cannot be reached from the roof or clean-outs.
-
Is high-pressure jetting safe for old cast iron?
Yes, when done by experienced technicians with the right nozzles and pressure. The camera inspection also shows if the pipe is too damaged to jet safely.
-
What causes kitchen stacks to block?
Grease, oil and food waste from many suites cool and stick inside the stack, combining with soap residue into hard deposits that narrow the pipe over time.
-
Do you provide proof that the stack is clean?
Yes. Every cleaned stack is recorded on camera and you receive a written condition report.
-
What is the difference between cleaning and replacing a stack?
Cleaning removes build-up from a sound pipe. Replacement or lining is needed when the pipe is cracked, corroded or has failed joints.
-
Will cleaning fix a stack that has backed up more than once?
Usually, yes, if the pipe is sound. If the camera shows damage, the stack may also need repair or lining.
-
Who pays for kitchen stack cleaning?
The shared stack is normally a common element, so the condo corporation pays for scheduled cleaning. Responsibility for damage depends on the building declaration.
-
My sink backed up and damaged my floor. Who pays?
It depends on the cause and your building declaration. We document the cause in a report that management and insurers can use.
-
How much does kitchen stack cleaning cost?
Full-height jetting typically costs $400 to $1,000 per stack, plus camera reporting. Buildings receive a program price based on the number and height of stacks.
