CCTV Drain Surveys
A CCTV drain survey provides a clear, accurate view of the condition of your drainage system without excavation.
Using high-resolution camera equipment, we inspect your drains internally to identify blockages, structural defects, and underlying issues that are not visible from the surface.
This is the fastest and most reliable way to diagnose drainage problems correctly.
What Is a CCTV Drain Survey?
A CCTV drain survey involves inserting a specialist camera into the drainage system to record live footage of the internal pipework.
This allows us to pinpoint the exact location and cause of issues such as cracks, collapses, root intrusion, and recurring blockages.
The survey removes guesswork and prevents unnecessary work.
When Do You Need a CCTV Drain Survey?
CCTV surveys are recommended for:
Repeated or unexplained blockages
Slow drainage with no visible cause
Suspected drain damage or collapse
Property purchases and pre-sale checks
