What drives the price, the indicative range to know, and why camera inspection prevents unpleasant surprises.
| Factor | Possible effect on price | Question to ask |
|---|---|---|
| Accessibility of the cleanout | Difficult access lengthens the job | “Do you need special access at my place?” |
| Cause of the blockage (grease, roots, sagging) | A structural cause goes beyond simple unclogging | “What caused the blockage, and how do you confirm it?” |
| Timing of the call (evening, night, holiday) | Some windows carry premium rates | “Does pricing change with time of service?” |
What drives the price of an unclogging
First factor: accessibility. A clean, easy-to-reach cleanout allows a direct intervention; a buried, missing or unusable access forces the professional to work from another point of the network, sometimes inside the home itself, with more time and care.
Second factor: the line itself. The longer, older or more convoluted the run (multiple bends, mixed materials), the more passes the intervention demands. A blockage near a kitchen exit does not cost the same effort as a plug lodged several metres down the main line.
Third factor: the cause. Compacted grease or a wedged object clear relatively fast; roots that have colonized a joint, or a sagging section, change the nature of the job: from troubleshooting to site diagnosis. That is precisely why camera inspection exists: telling these cases apart.
Indicative ranges: a benchmark, not a quote
In Quebec, drain unclogging (with camera inspection when needed), generally sits within an indicative range of $220 to $1,800. The low end matches simple jobs on accessible networks; the high end reflects complex situations: long runs, structural causes, additional work discovered along the way.
This range is indicative and to be confirmed on site. Be as wary of miracle prices quoted over the phone without a single question as of dizzying amounts given without explanation. A serious professional asks questions (symptoms, location, history), then confirms pricing after seeing the situation firsthand: not before.
Our concrete advice: ask that the price and what it covers be clarified before work begins: what is included (unclogging passes, camera inspection, report), what could be added, and under which conditions. That two-minute conversation eliminates most billing disputes.
What camera inspection is really for
Camera inspection means feeding a small camera into the line to view its interior in real time. It shows what no blind snaking can reveal: the state of the walls, root intrusion, a displaced joint, early sagging, or simply confirmation that the line is clean after the job.
Its most valuable contribution remains localization: combined with locating equipment, it pinpoints where along the line the problem sits. That information changes everything if heavier work proves necessary: fewer exploratory digs, tighter estimates, better-informed decisions.
And it documents. A before/after recording is proof of the work performed, useful with an insurer, a prospective buyer, or simply to track an ageing line’s evolution. Ask the verified RBQ-licenced contractor visiting you whether they provide a copy: an increasingly common good practice.

What these numbers do not cover
The range is a Quebec order of magnitude; duration, access and the cause of the block change it, and only a quote sets the price.
