The same drain keeps clogging
After flow has been restored, the camera can look for a persistent cause: roots, a displaced joint, recurring buildup, deformation or another visible defect.
DRAIN CAMERA INSPECTION • GREATER MONTRÉAL
Drain camera inspection: what a plumber must check
It should answer one specific question: why does the drain keep clogging, where is the problem located and what work is actually justified? The choice of access point, preliminary cleaning, distance reading and deliverables determine the value of the result.
SOS Plombiers receives drain camera inspection requests 24 hours a day, 7 days a week, gathers the relevant information and attempts to assign them to a plumber in the network based on the address, type of pipe, requested scope and availability.
Specify from the outset whether you only want to understand a recurring problem or need a recording, surface locating, a written report, a sketch or documentation for a municipality, insurer or real estate transaction.
- Requests received 24/7
- Diagnosis, video and report are separate deliverables
- Price and deliverables confirmed by the plumber
WHEN THE IMAGE CAN CHANGE THE DECISION
Four situations that do not require the same inspection
Defining the objective before the appointment helps avoid paying for a video that does not answer the right question.
A break must be located
The image helps characterize the affected section. A compatible transmitter and locator can then be used to mark an approximate position and depth from the surface.
The sewer connection raises concerns
A targeted inspection can document the section of pipe viewed before a transaction, without replacing the general building inspection or covering branches that were not inspected.
A municipality or insurer requires documentation
A report, distance reading, on-screen address, sketch and specific video format may be required. These requirements must be confirmed before the visit.
CHOOSE THE RIGHT FIRST STEP
Camera inspection, drain cleaning or repair: the symptom determines the scope
The camera observes; it does not clear or repair the drain. When a pipe is full of water, grease, roots or other debris, visual access may need to be restored before usable images can be obtained.
| Observed situation | First service often recommended | What it should clarify |
|---|---|---|
| One kitchen sink, bathroom sink or bathtub is draining slowly for the first time | Drain cleaning | Treat a likely localized blockage first; a camera inspection is not automatically required. |
| The main drain keeps clogging or several fixtures react at the same time | Drain cleaning followed by inspection, depending on access | Restore flow, then document the cause if the problem is recurring or remains unexplained. |
| Sewage is backing up through a floor drain, toilet or another low point | Sewer backup response | Secure the area and restore drainage before deciding when the inspection should be performed. |
| A crack, sag or deteriorated section has already been documented | Main drain repair assessment | Confirm the affected section, method, access points and actual scope of work. |
After a recurring problem: the guide to the causes of a repeatedly clogged main drain helps you prepare the history to share with the technician.
WHAT THE CAMERA CAN DOCUMENT
Visual observations within the section inspected
- roots, grease, buildup, an object or a residual blockage;
- an open or misaligned joint, change in material or visible connection;
- a crack, crushing, corrosion, deformation or apparent collapse;
- standing water or an apparent low spot under certain conditions;
- distance travelled when the equipment displays a counter or distance reading;
- a point to be located when the camera head has a compatible transmitter.
WHAT A VIDEO CANNOT PROVE ON ITS OWN
A useful image is not a universal verdict
- It does not confirm that every pipe in the building is watertight.
- It does not automatically measure the pipe’s design slope.
- It does not show inaccessible or submerged sections, or sections located beyond an impassable blockage.
- It does not locate a defect from the surface without an appropriate transmitter and locator.
- It does not determine private or municipal responsibility on its own.
- It does not guarantee that a blockage will never return.
CERIU notes that a televised inspection gathers observations about the interior condition of a pipe at a specific point in time and that the objective of the inspection must be defined beforehand. This distinction is essential between a routine residential diagnosis and a formal inspection performed under a municipal or technical protocol.
DRAIN CAMERA INSPECTION COST
A realistic budget depends on access and what you want to receive
For a residential inspection in the Montréal area, publicly available price ranges may run from approximately $300 to $1,000 before tax. A simple inspection through an accessible cleanout is not comparable to clearing a blocked pipe, inspecting several branches or preparing municipal documentation with video, a report and a sketch.
MARKET RANGEApproximately $300 to $1,000
Inspection, travel and deliverables vary by company and scope.
This amount is a general price range, not a quote from SOS Plombiers. The assigned plumber must confirm the charges, inclusions, minimum billable amount and any possible additional fees before the service call.
Factors that affect the cost
- an existing cleanout, a toilet that must be removed or another access point that must be prepared;
- drain cleaning, root cutting or other cleaning required before the inspection;
- the length, diameter, bends, branches and number of pipes to inspect;
- appointment time, travel and the presence of a second technician;
- video recording, digital delivery and an on-site explanation;
- transmitter, surface locating and depth estimate;
- a report, sketch, photos or form intended for a third party.
Read the detailed guide to drain camera inspection costs, then ask the plumber to clearly distinguish between the inspection, cleaning and deliverables.
VIDEO, LOCATING, REPORT AND SKETCH
The word “inspection” does not guarantee that all deliverables are included
Ask for a written list of what will be provided. Viewing the images on the technician’s screen is not the same as receiving a video file, and a video is not the same as a signed report.
On-site explanation
Observations shown on the screen, limitations encountered and options discussed before any additional work.
Video recording
The format, delivery method, date, address and distance reading must be confirmed based on the intended use of the file.
Surface locating
A separate service using a compatible transmitter and locator to mark an approximate position and depth.
Report or sketch
The recipient, form, measurements, signature and required information must be specified before the appointment.
Real estate transaction: also ask whether the file can be identified and reviewed after the visit. A video without an address, date or distance reference may be less useful for comparing observations or supporting a decision.
FROM THE SYMPTOM TO A DOCUMENTED DECISION
How does a plumber inspect a drain with a camera?
The order may vary depending on the access point and the condition of the pipe. The objective remains the same: to obtain images clear enough to guide the next decision without turning a limited observation into excessive certainty.
For more information about each step, also see the guide to the drain camera inspection process.
Define the question
The history, affected fixtures, recurrence, building type and required document are clarified.
Choose the access point
The cleanout or appropriate opening is checked based on the target pipe and equipment.
Make a clear view possible
Drain cleaning or another cleaning method may be proposed if water, roots or deposits prevent usable images.
Inspect and locate
The camera travels through the accessible section; available observations and distances are recorded.
Interpret and deliver
The plumber explains the limitations, provides the agreed deliverables and prices any proposed follow-up work separately.
MUNICIPAL DOCUMENTATION IN GREATER MONTRÉAL
A standard residential inspection is not automatically accepted by a municipality
Requirements vary by municipality, borough and procedure. Before the appointment, send the applicable form to the plumber and confirm that every required document can be produced.
Montréal
For a sewer lateral repair request, the City may require a report and video showing the entire sewer line to the public section, with the distance reading clearly visible. It may also require roots or obstructions to be removed when necessary.
Longueuil
When the condition of the public section of the sewer lateral is in question, municipal regulations require the owner to provide a camera inspection before corrective work. The City also specifies that the sewer lateral must be cleared before the camera inspection.
Laval
If a company attributes a defect to the public section of the sewer lateral, the City asks residents to contact 311 and retain a detailed invoice. Its claims page specifies that camera inspection fees are not among the listed reimbursable expenses.
These summaries do not replace current municipal forms. SOS Plombiers forwards the request; the assigned plumber must confirm that the requirements applicable to your address can be met.
PRE-PURCHASE OR PRE-RENOVATION INSPECTION
Inspect a defined pipe, not “all the plumbing” under a single promise
During a real estate transaction, a camera inspection can provide information that is otherwise difficult to obtain about an accessible sewer lateral. It is especially relevant when there is a history of sewer backups, repeated drain cleaning, roots, sewer repairs or recent basement finishing.
However, it does not replace a general pre-purchase inspection or checks specific to water supply pipes, the foundation drain, plumbing fixtures or inaccessible sections.
- identify the pipe to be inspected and its access point;
- obtain the required authorization from the owner or condominium association;
- ask whether the complete video will be provided in a format that can be retained;
- have all travel or visibility limitations documented;
- separate the observations, interpretation and repair estimate.
QUESTION TO ASK BEFORE BOOKING
“Which pipe will actually be inspected, and how far do you expect to be able to go?”
This question requires clarification of the available cleanout, diameter, bends, length, private section and intended use. It is more useful than a vague promise of a complete inspection.
A foundation drain located around the foundations requires a different access strategy and interpretation from a sanitary sewer lateral. State explicitly which one you want inspected.
HOUSE, CONDOMINIUM AND COMMERCIAL BUILDING
The pipe is underground, but the practical constraints of the job are very real
House
Locate the cleanout, gather previous reports and indicate whether the basement is finished. Describe any drain cleaning, sewer backups, exterior work or tree planting near the presumed route.
Condominium or plex
Specify whether the pipe is private or shared, who authorizes access, which units are affected and whether a shutdown or usage restriction must be coordinated.
Commercial or multi-unit building
Provide the access hours, operations that must be maintained, branches to identify and the person authorized to approve the work. For a broader scope, see the commercial plumbing services.

TECHNICAL REFERENCES USED
Sources that distinguish a visual observation from a complete diagnosis
CERIU guides focus primarily on structured sewer network inspections, but their principles are useful: define the objective, document the limitations and clean the pipe when deposits prevent a conclusive inspection.
FREQUENTLY ASKED QUESTIONS
Drain camera inspection: answers before booking
The answers below concern the inspection of an accessible pipe. The plumber must confirm what applies to the building and the scope.
Is a camera necessary every time a drain is clogged?
No. A recent, localized blockage can often be treated without a camera. An inspection becomes particularly useful when the problem recurs, affects a shared pipe, remains difficult to locate or suggests a pipe defect.
Does the drain need to be cleared or cleaned before the inspection?
Sometimes. A camera cannot pass every blockage or produce a clear image in a pipe filled with water or debris. The plumber must specify whether drain cleaning or other cleaning is necessary and whether it is billed separately.
How much does a drain camera inspection cost in Montréal?
Publicly available price ranges may be approximately $300 to $1,000 before tax. The cost depends on access, preliminary cleaning, length, number of branches and deliverables. Only the plumber’s estimate confirms the applicable price.
Are the video and written report always included?
No. On-site viewing, the recording, download link, locating, report and sketch may be separate deliverables. Ask for written confirmation of what will be provided.
Can a break be located precisely from the surface?
A compatible camera head or transmitter can be detected with a surface locator. The position and depth remain approximate and depend on the equipment, depth, route and interference. The video alone does not perform this locating.
Can the camera measure the drain’s slope?
Standing water may reveal an apparent low spot, but a standard video does not automatically measure the design slope of the entire pipe. The interpretation must account for the equipment and conditions during the inspection.
Is a camera inspection suitable for a real estate purchase?
It can supplement a pre-purchase inspection when a specific sewer lateral raises concerns. It does not replace the general building inspection and cannot support conclusions about pipes or branches that were not inspected.
Is a foundation drain inspection the same thing?
No. A sewer lateral carries wastewater away from the building, while a foundation drain is generally located around the foundations. The access points, symptoms investigated and assessment methods differ. Specify the type of drain when submitting the request.
Can the drain be inspected through a toilet?
It may be possible in some configurations, but it is not always the preferred or included access point. The cleanout, diameter, bends and type of camera determine the access. Any fixture removal and reinstallation must be included in the price details.
Who confirms the diagnosis, price and deliverables?
SOS Plombiers receives and assesses the request, then attempts to assign it to an available plumber in the network. The plumber checks the access, interprets the images, confirms the charges and provides the agreed deliverables.
A PRECISE QUESTION PRODUCES A MORE USEFUL INSPECTION
Describe the drain, its history and the document you need
Provide the address, building type, affected fixtures, frequency of the problem, available cleanout and reason for the inspection. SOS Plombiers will attempt to direct the request to a plumber in the network who can confirm the access, timing, price and deliverables.
The assigned plumber remains responsible for the interpretation, estimate, work, invoice and warranties.
