Common problems
What goes wrong with drains?
A CCTV survey shows us exactly what’s wrong, and that decides whether a pipe can be lined or needs digging up.
Cracks and fractures
Often lined, with no digging.
Displaced joints
Small movement can be lined. Badly displaced joints usually need digging out.
Root ingress
Roots cut out first, then the pipe is usually lined.
Collapse or deformation
Usually needs excavation and a new section of pipe.

Questions answered
CCTV survey FAQs
What is a CCTV drain survey?
A survey where a waterproof camera is sent through your drains to record their condition. It finds cracks, roots, blockages, collapses and displaced joints without any digging.
Which survey do I need?
If you’re buying, get a home buyers survey. For a septic tank, a septic tank survey. For repeat blockages, a look and see is often enough, and for building work, drain tracing and mapping. Use the chooser above, or call us and we’ll advise.
How often should drains be surveyed?
Most homes only need a survey when buying, after repeated problems or before building work. Busy commercial sites may benefit from a survey every one to three years.
How long does a survey take?
Most domestic surveys take one to two hours, depending on the size of the property and the access.
Can you fix the problems you find?
Yes. We carry out drain lining, excavation and repairs, and can quote from the survey findings.
