An inspection should answer a specific question.
Explain the performance problem: water collecting in a new area, a previously dry lawn staying wet or a change at an existing outlet. The assessment should distinguish system condition from changes in the water reaching it.
A visible wet area does not identify the buried cause. Roof runoff, grading, groundwater, receiving capacity and damaged or obstructed components can overlap.
Information to gather without disturbing the system.
- When the symptoms began and which conditions trigger them.
- Approximate installation age, route and any product or layout records.
- Known cleanouts, accessible outlets and sump components.
- Recent construction, tree or landscape changes.
- Areas and surfaces that would be affected by excavation.
Inspection methods depend on access and components.
A professional may assess the visible route, outlet, accessible pipe or pump arrangement. The method should suit the actual system. Do not assume every French drain has a camera-compatible pipe or cleanout.
Ask what the findings establish and what remains uncertain. A partial inspection should not be represented as proof that every buried section is clear.
Turn findings into a repair decision.
Cleaning can address certain obstructions. Damaged pipe, clogged aggregate, unsuitable filtration or a restricted receiving location may require different work. Ask how the proposed scope follows from the observations.
Keep inspection findings with the installation records. They are useful for comparing repair proposals and planning later maintenance.
Common questions
Does an inspection always require excavation?
Not always. Accessible outlets and components may provide useful evidence, but some buried conditions require further access.
Can a camera inspect every system?
No. Pipe type, size, access and layout affect the available methods.
Does a clear pipe prove the entire drain works?
No. Collection materials, water loading and the receiving location also influence performance.
