Before you book
What you need to know.
- CCTV can show accessible defects, obstructions and connections after visibility is established.
- Clearing may be needed first. A camera looking into standing dirty water has limited value.
- Footage and locating answer different questions: what the defect looks like and where it sits.
- Agree the inspected line, reporting requirements and limitations before comparing repair quotes.

When a camera inspection earns its place.
If the same drain has been cleared repeatedly, an inspection can help explain the pattern. It can also assess a damaged section before choosing a repair. Start with a specific question: why does this sewer block, where is the defect, or what needs repairing?
Scott & Sons provides CCTV drain investigation and camera location. Explain the purpose when booking. Investigating a recurring blockage differs from checking a property's entire drainage for a maintenance record. Multiple access points and formal reporting change the work involved.
What the images can show.
The camera provides a close view of the interior as it travels from a suitable access point. Visible roots, deposits, cracks and joint displacement can help explain a restriction. A recording gives context that a still photograph can miss, including the pipe before and after the defect.
Images need interpretation. A mark isn't automatically a structural failure, and standing water doesn't by itself prove the exact cause of a grading problem. Findings should distinguish what's visible, what's suspected and what requires more investigation.
Scroll sideways to read every column.
| Finding | Useful question | Possible next step |
|---|---|---|
| Roots at a joint | Where is the entry point and how is the joint affected? | Assess cleaning and targeted repair. |
| Heavy deposits | Is the underlying pipe visible? | Clear material before judging condition. |
| Displaced or damaged section | How long is the affected area? | Compare internal repair and replacement. |
| Standing water | What could be restricting flow here? | Investigate the line and layout. |
| Camera can't proceed | Is the limit a bend, obstruction or damaged section? | Record the limit and agree further investigation. |
Why preparation and visibility matter.
Dirty water or dense material can hide the surface the camera needs to show. The line may need clearing before useful inspection is possible. In some cases an initial view helps plan clearing; in others the obstruction must be addressed before the camera travels.
Bends, junctions, changes in diameter and a complete collapse can limit access. Reaching part of a line doesn't certify everything beyond it. A useful result includes the starting point, extent reached and uninspected sections, so a partial inspection isn't mistaken for a whole-property clearance.
Locate the defect before planning access.
Footage shows the inside of the pipe. Surface locating relates a point inside that pipe to a position at the property, where equipment and conditions allow. This helps plan targeted access rather than relying only on an old sketch or assumed straight pipe run.
Confirm whether locating is included and how the position will be recorded. Depth estimates and surface marks need context around structures and other services. An inspection location supports planning; it doesn't replace the checks required before excavation.
Agree what you need from the report.
A homeowner deciding on a repair, a strata manager seeking approval and a contractor planning work can need different information. Say who will use the findings. Ask whether video, selected images, a plan or a written summary is included and how it will be delivered.
The record should identify the line, visible findings, access limitations and recommended next steps. Provide any specific approval or contract requirements before booking. A routine inspection doesn't automatically produce every document a third party might request.
- Property address, inspection date and starting access point
- Which line and accessible sections were inspected
- Location and nature of visible defects
- Clearing completed before inspection
- Uninspected sections and visibility limitations
- Footage or written findings included in the price
Turn the inspection into a proportionate repair plan.
Replacement isn't an automatic outcome. A removed object, localised defect and extensive damage call for different recommendations. Inspection can support cleaning, monitoring, a targeted repair, relining or replacement, depending on the evidence and conditions.
Compare quotes for the same section and result. Keep original findings alongside the repair proposal. If visibility was too limited for a firm conclusion, resolving that uncertainty can be the next job before selecting a method. A clearly stated limitation is useful information when it prevents a repair being based on an assumption.
Define the question
Explain the symptom, previous work and decision the inspection needs to support.
Confirm access and visibility
Assess whether clearing is needed and which sections can be reached.
Inspect and record
Relate visible conditions to the line and note any limits.
Review the options
Use the findings to agree further investigation or a repair scope.
