A camera down a drain sounds like overkill, until you’ve paid to clear the same blockage three times. Here’s when a CCTV drain survey genuinely earns its money.
The clear cases
- Recurring blockages: clearing removes the symptom; the camera shows the cause (roots, scale, a belly in the pipe, a collapsed section).
- Damp appearing near drain runs: a cracked drain can feed “mystery damp” into walls and floors for years. Pairing a drain survey with a damp survey catches it.
- Persistent smells: often a fractured or poorly-connected pipe venting under the property.
- Rats indoors: broken drains are the classic entry route.
- Buying a house: drains are expensive to replace and invisible on a standard survey.
What you get
Recorded footage, the fault located and measured (position + depth), and a written report suitable for insurance or purchase negotiation. If the drain fault has caused internal leaks or damp, we investigate that too: leak detection.
