Drain camera inspection · Video diagnosis
Drain camera inspection
See inside an accessible drain or sewer line before deciding what to repair. A professional video inspection can help identify the likely cause of recurring clogs, unexplained backups and abnormal drainage without starting with excavation.

The right test at the right time
When a camera inspection provides a useful answer.
Not every slow drain needs to be scoped. A drain line camera inspection becomes especially valuable when the problem keeps returning, its location remains uncertain or a costly decision depends on the pipe’s actual condition.
The same drain keeps clogging
A blockage that returns after service may point to persistent buildup, tree roots, an offset joint or a damaged section of pipe.
Objective: understand why the problem returns.A repair or property purchase is being considered
Before excavation, a major renovation or a real-estate purchase, a sewer camera inspection can document the visible condition of an accessible line.
Objective: decide from images instead of assumptions.The emergency comes before the camera
If contaminated water is rising or several fixtures are backing up, stop using water. A complete obstruction may need to be cleared before the camera can travel through the line.
Priority: protect the area and restore access.What the footage may reveal
Visible clues inside the drain line.
A plumbing camera inspection shows the inner surface and behaviour of the section travelled. For an accessible main drain or sewer line, interpretation also considers the pipe material, access point, observed position and symptoms in the building.
Tree root intrusion
Roots can enter through an opening, joint or weakened section and trap material until the line clogs again.
Cracks, breaks and deformation
A drain inspection camera may show a visible crack, broken section, change in shape or a partially collapsed passage.
Offset or misaligned joints
A displaced connection can narrow the passage, catch debris or indicate movement between two sections of pipe.
Buildup and deposits
Grease, sludge, scale, residue or compacted material may appear along the walls and explain reduced capacity.
Standing water and pitch concerns
Water remaining in one area can suggest a sagging section, improper slope or an obstruction. The footage guides the diagnosis but does not replace any measurements or additional tests that may be needed.
Obstruction or foreign object
When the path remains visible, the camera may identify the point where an object or blockage is interrupting drainage.
A clear diagnostic process
From the symptom to the next decision.
The quality of a video drain inspection depends on more than the camera. The plumber must choose a useful access point, obtain a sufficiently clear passage and interpret the footage in the context of the property.
A fully blocked, submerged, narrow or inaccessible line may prevent a useful inspection. Drain cleaning or unclogging may need to come before the camera pass.
- 01
Define the symptoms
Identify the affected fixtures, frequency of clogs, odours, sounds, backups and any previous work on the line.
- 02
Select an appropriate access point
A compatible cleanout or other opening is chosen according to the line being examined and the property’s configuration.
- 03
Prepare the line
The path must be clear enough for the lens to move forward and for the pipe walls to remain visible.
- 04
Inspect and observe
The camera travels through the accessible section while deposits, joints, obstructions and changes in condition are noted.
- 05
Review the options
The observations help distinguish between cleaning, monitoring, further testing and a targeted repair.
Clear diagnosis without overpromising
What the camera shows—and what it cannot prove alone.
Clear footage reduces uncertainty, but it does not replace physical access, the history of the problem or testing for conditions outside the pipe.
The visible condition of the travelled section
The camera can show pipe walls, accessible connections, buildup, obstructions and abnormal areas along the route it can reach.
- Real-time images from inside the line
- Relative position of visible concerns
- Evidence for choosing the next step
Conditions outside the frame or beyond access
The camera cannot see through a complete clog, inspect the soil around a pipe or show a section it cannot enter. A dirty line may also hide a defect.
- No view beyond a complete obstruction
- No direct assessment of the surrounding soil
- Additional testing may still be required
Residential and commercial inspection
An inspection matched to the property and the decision.
Drain camera inspection is available in covered areas across Laval, the North Shore and Montreal. Whether the property is a house, plex, condominium, rental building or business, access and the section to inspect are confirmed according to the site.
For a pre-purchase request, insurance matter or planned project, mention whether you require images, recording, pipe locating or a particular document. Available deliverables and the inspection scope can then be confirmed before the appointment.

Four details that make the inspection more useful.
Good preparation helps identify the correct line and provides the context needed to interpret what appears on screen.
Exact symptoms
Note which fixtures react, on what floor, for how long and whether the problem follows heavy water use.
Drain history
Mention earlier clogs, cleanings, repairs, sewer backups and any products already used.
Known access point
Locate—but do not dismantle—the cleanout or access used during a previous service call.
Required outcome
State whether the inspection is for diagnosis, a purchase, renovation, insurance matter or repair planning.

Frequently asked questions
What to know before a sewer camera inspection.
If several fixtures are backing up or contaminated water is rising, stop using water and call. The plumbing emergency may need to be stabilized before inspection.
24/7 PLUMBING EMERGENCY450-241-0488What is a drain camera inspection?
A waterproof camera attached to a cable is inserted through a compatible access point to view the inside of a drain line. It provides footage of the section travelled and may reveal a blockage, roots, buildup, an offset joint or visible damage.
When should a drain line be inspected with a camera?
Camera scoping is particularly useful when a clog returns, symptoms remain unexplained, pipe damage is suspected, underground repairs are being considered or a focused check is requested before a property purchase or renovation.
Can the camera pass through a completely clogged drain?
Not always. A complete blockage, opaque standing water or heavy deposits can stop the camera or hide the pipe walls. The line may need to be unclogged or cleaned before useful footage can be obtained.
Can a sewer camera find tree roots or a broken pipe?
It may show visible roots, cracks, breaks, deformation, sagging sections or misaligned joints in the accessible portion. Image quality and site conditions affect interpretation, and major work may still require additional confirmation.
Is a sewer line camera inspection useful before buying a house?
It can be valuable when you want a closer look at a line that is not visible during a standard building inspection, especially with an older property, a history of backups or possible underground work. Confirm the scope and required deliverables before booking.
How much does a drain camera inspection cost?
Cost depends on the number of lines, accessibility, distance travelled, preparation required and requested deliverables. Explain the purpose of the inspection by phone so the scope can be clarified before the service call.
How long does a video drain inspection take?
Timing varies with the access point, pipe length and condition, obstructions encountered and number of sections to examine. A known cleanout and a sufficiently clear line generally make the inspection more efficient.
Does a camera inspection require excavation?
The camera is normally introduced through a compatible existing access point, so the inspection itself does not usually require digging. If no suitable access exists or structural damage is confirmed, separate work may be proposed.
Do you provide drain camera inspection in Laval, the North Shore and Montreal?
Yes, throughout covered areas. The address, building type, line to inspect, availability and any special requirements are confirmed by phone before travel.
