A drain camera inspection uses a waterproof, flexible camera mounted on a long cable to transmit live video of the inside of a drain or sewer line to a screen that the plumber monitors in real time. The camera travels through the line from an access point such as a cleanout or drain opening, capturing the condition of the pipe wall, the nature of any blockage, the location and extent of root intrusion, and the structural condition of the line itself.
The result is a precise, visual diagnosis rather than a best guess. When a plumber knows exactly where a blockage is, what it consists of, and whether the surrounding pipe is intact or damaged, the recommended clearing method and any required repair work is based on facts rather than assumptions. This protects you from paying for a repair that does not address the actual problem. Galaxy Plumbing uses drain camera technology across all types of drain and sewer line assessments in the GTA.
If the same drain has been cleared more than once in a 12-month period and continues to slow or block, the inspection confirms whether the recurring problem is caused by persistent buildup on the pipe wall, a structural defect creating a debris-collection point, a partial root intrusion that clears temporarily but regrows, or a narrowing in the pipe from scale or corrosion. Without a camera, the plumber is clearing the same symptom each time without knowing what is causing it.
When two or more drains in the home are slow simultaneously, the main sewer line is the shared component most likely responsible. A camera inspection of the main line identifies where and what the obstruction is, whether it is a soft blockage, a root mass, a sagging pipe section, or a collapsed segment, and guides the selection of the appropriate clearing method. This prevents applying the wrong tool to a problem that will not respond to it.
A drain camera inspection is one of the most valuable pre-purchase assessments a buyer can commission, particularly for homes more than 20 years old. Standard home inspections do not include a sewer scope. The camera reveals the condition of the sewer lateral, the drain line material, any existing root intrusion, pipe degradation, or offset joints. Discovering that a sewer line requires relining or partial replacement before the sale closes is information that belongs in the negotiation, not in the first year of ownership.
For buyers working with properties in Toronto, Mississauga, Oakville, or Scarborough, our Toronto plumbing team and Oakville plumbers provide pre-purchase sewer scope services with a written report.
When roots have been identified in a sewer line and cleared through hydro jetting or mechanical cutting, a follow-up camera inspection confirms that the line is clear and provides a baseline assessment of pipe condition. It also identifies whether the root entry points, the cracks or joint separations the roots exploited, require pipe lining or repair to prevent reinfection. Clearing roots without inspecting the pipe condition leaves the underlying vulnerability unaddressed.
A camera inspection before hydro jetting confirms the pipe's structural suitability for high-pressure cleaning. An inspection after jetting confirms the result, documenting that the pipe is clear and the wall is clean. For commercial properties where drainage performance is critical to daily operations, post-jetting camera documentation provides a service record and a liability baseline. Galaxy Plumbing's commercial drainage services include pre and post-service camera documentation on request.
Persistent sewage or sulphur odours inside a home, particularly in the basement, indicate that sewer gases are entering the living space. The sources include dried drain traps, cracked pipe sections, offset joints that have separated, and in some cases, deteriorated wax seals at toilet bases. A camera inspection of the drain lines identifies structural defects that allow gas passage, which visual inspection from outside the pipe cannot detect.
Any excavation, landscaping work, or foundation repair near where the main sewer line runs under the yard can disturb, displace, or damage the pipe. A camera inspection after this type of work confirms that the line is intact, undislocated, and free from debris that may have entered through disturbed soil or a jarred joint.
For homes built before 1980 where the original owner no longer occupies the property and no plumbing service records exist, a drain camera inspection is a prudent baseline assessment. It establishes what pipe material is in use, whether cast iron has corroded, whether clay pipe joints have separated, and whether any sections of the line require preventive attention before a crisis develops.
The information a camera inspection provides goes well beyond confirming whether a clog exists.
This level of diagnostic specificity is what makes a camera inspection the professional standard before major drain repair or replacement decisions. Without it, pipe repair decisions are based on incomplete information. Galaxy Plumbing's full residential services include camera inspection as a standalone service and as part of clearing and assessment packages.
A standalone drain camera inspection in the GTA typically ranges from $150 to $350, depending on the length of line being inspected, access point conditions, and whether a written report or recorded footage is provided. When bundled with a drain clearing service, the camera inspection cost is often reduced or included in the total visit price.
The return on that investment is clear in scenarios where the inspection prevents an incorrect repair. A homeowner who spends $200 on a camera inspection and discovers that the recurring clog is caused by a cracked pipe sagging at one joint avoids paying for repeated hydro jetting visits that will never permanently solve a structural problem. The camera pays for itself in the first decision it informs correctly.
The inspection leads directly to a specific course of action based on what the camera reveals. Soft blockages are cleared by the appropriate method, snaking or hydro jetting, depending on the composition of the obstruction. Root intrusion is addressed with mechanical cutting and hydro jetting, followed by an assessment of whether pipe lining is needed to close the entry points. Structural defects such as offset joints, collapsed sections, or severe corrosion are assessed for pipe relining or replacement.
A licensed plumber who performs the inspection also makes the clearing or repair recommendation, which means the person with the visual information is the same person proposing the solution. This continuity produces better outcomes than situations where a different party inspects and another clears without shared information.
For homeowners wanting to understand more about Ontario's standards for drain system assessment and repair, Skilled Trades Ontario provides licensing and standards information relevant to plumbing and drain work in the province.
Drain issues that are diagnosed visually produce better repair outcomes than those addressed through assumption and repetition. A drain camera inspection gives the plumber and the homeowner the same information at the same time, allows for a shared understanding of the problem, and produces a repair recommendation grounded in what is actually happening inside the pipe.

The Canada Mortgage and Housing Corporation includes sewer scope inspection as part of its recommended home maintenance guidance for Canadian homeowners, particularly at the time of purchase.
A residential drain camera inspection of the main sewer line typically takes 30 to 60 minutes, including setup, the full length of the inspection, and the post-inspection review with the homeowner. Inspecting multiple lines or a longer commercial drain system takes proportionally longer.
Most professional plumbers can provide recorded footage of the camera inspection on request. Ask when booking the service whether a recording and a written summary of findings is included or available as an add-on. This documentation is valuable for insurance purposes, home sale disclosure, and future plumbing service reference.
Not all drains in the home are suitable access points for a main sewer line inspection. The most common access points are cleanout fittings in the basement or near the foundation, or the toilet base after the toilet is removed. A plumber will identify the most appropriate access point during the assessment.
If the inspection identifies a structural defect, the plumber will explain the finding, its location, and the options for repair. These typically include pipe relining, which installs a new pipe liner inside the existing pipe without excavation, or pipe replacement for severe damage. The inspection itself does not obligate you to any repair. It simply gives you accurate information to make an informed decision.
Not necessarily. For a straightforward, first-time blockage in an accessible fixture drain with no history of recurrence, a camera inspection may not be required before clearing. It becomes necessary when symptoms suggest a main line issue, when clearing has not produced lasting results, when the pipe age or history raises structural concerns, or when a property transaction is involved.
