In short
- Sewer line cleaning runs $230–$590 in a Canada-wide HomeStars guide, a benchmark; the company prices your drain after it hears the details.
- One Ottawa firm calls hydro-jetting pricier than snaking and suited to serious clogs and long-neglected drains.
- Drain size matters most once it passes two inches, and a camera or jetting machine adds cost, the same firm notes.
- Restaurants in Ottawa must have a grease interceptor under Sewer Use By-law 2025-94; homes are asked to keep grease out of the drain.

When a cable falls short
A cable opens a path through a clog. The pipe wall stays coated, and grease or scale rebuilds the blockage. Drains that clear and then slow again within weeks are the usual jetting candidates. So are kitchen lines that carry years of grease, and older metal pipes with mineral scale.
One Ottawa firm describes jetting as high-pressure water that strips layers of grease, compacted hair, soap scum, food residue and mineral deposits from the pipe wall, and says it can remove fragments of infiltrating tree roots. The same firm calls it ideal for serious clogs or long-neglected drains.
What the visit involves
The company starts by finding out what it is dealing with. A camera locates the clog and shows the cause, and some firms include it for larger drains while others bill it. Then the jetter goes in through a clean-out or a fixture opening, and water pushes debris toward the sewer. A second look can confirm the pipe is clear.
The sequence is the company’s call, because it depends on pipe size and condition. Send the details in the request and leave the method to them.
Pipes that need care
Of the lateral blockages the City names, jetting deals with the soft ones: grease, paper, kitchen scraps, small objects, and roots in the pipe bore. It does not repair a collapsed section, and a camera that shows a collapse changes the plan to sewer line repair.
Pipe age matters. One firm writes that homes with aging clay or cast-iron pipes are especially open to root intrusion. The same firm says roots find tiny cracks and gaps in a sewer line. If the camera shows cracks, jetting alone may leave the roots to return.
What drives the price
We found no Ottawa firm that prints a jetting price. The nearest figures are Canada-wide: $230–$590 for sewer line cleaning, $165–$400 to unclog a drain and $400–$660 for a camera inspection. One Ottawa firm lists main sewer lines and toilets at $700–$2,000 for machine work in general.
The same firm names what moves the number: line length and condition, severity of the clog, access to the problem area, and whether roots or solid obstructions are present. Drain size matters especially above two inches. If the pipe needs repair before it can be cleaned, that is added to the quote.
Grease at home and in the kitchen
The City’s wastewater page says liquid fats, oils and grease solidify and stick to your plumbing or to City sewer pipes, and lead to blockages and backups. It asks residents not to pour them down sinks or toilets, not to use hot water or chemicals to push grease along, and not to use a food grinder. It also asks for strainers in sink drains. Compare costs for the whole range of drain jobs on the drain cleaning cost page, or see what a camera adds on the camera inspection page. The overview of every method sits on drain cleaning.
Written quote
A jetting quote should name the line being cleaned, from which access point to where, the pressure equipment, whether a camera before and after is included, and the cleanup. Ask for a note on what was found. If the debris was roots, ask what the company recommends next. If the camera shows damage on the City side of the property line, the written note and video are what you take to 3-1-1.
Who you are dealing with
The jetter, the crew and the invoice all belong to one independent Ottawa plumbing firm. Ottawa Plumbing Desk takes your description and passes it on; the firm calls back, chooses cable, jet or descaling for your pipe and names its price.
Questions to ask the company
- Do you run a camera before jetting, and does the price include it?
- What is the pipe material and age, and does that change how you jet it?
- Is the price for one pass or for cleaning the whole length to the street?
- Where does the loosened debris go, and who cleans up in the basement?
- If roots come back, what do you advise and what does a follow-up visit cost?
Have this ready for the call
- The clean-out location, usually a capped pipe in the basement floor near the water meter, with a metre clear around it
- The history: how many times this drain blocked, and when it was last cleared
- Whether a tree stands between the house and the street
- Pipe material if you know it, and the year the house was built
- Access: stairs, tight corners and parking near the front door
Questions people ask
How is hydro jetting different from snaking?
A cable punches a small opening through a clog. Jetting uses high-pressure water to strip grease, compacted hair, soap scum, food residue and mineral deposits from the pipe wall, one Ottawa firm explains, and it can cut root fragments. That is why it suits repeat clogs and heavy buildup.
Is jetting safe for old pipes?
One Ottawa firm says jetting is safe for PVC, copper and many types of older pipes when done by qualified plumbers. Aging clay and cast-iron lines are the ones most exposed to root intrusion. A camera first shows whether the pipe is sound enough, and the company decides the method after seeing it.
What is descaling?
Descaling removes hardened mineral deposits, especially in older metal pipes. One Ottawa firm lists it next to snaking and jetting as a separate technique, and says the price varies with the severity of the buildup and the condition of the pipe.
Do restaurants need anything beyond jetting?
Yes. The City of Ottawa says a grease interceptor is mandatory for restaurant owners and regulated under Sewer Use By-law 2025-94. Jetting clears what has already built up; the interceptor holds grease back before it reaches the line.
How soon should a drain be jetted again?
We found no published Ottawa schedule. The interval depends on what built up and why. The company that cleans the line can tell you after seeing the video or the debris, and write the interval into the invoice or follow-up note.
