A problem keeps returning
Investigate recurring blockages, slow drainage, leakage, odours or suspected root ingress instead of treating only the symptom.
Clever Works Ltd inspects accessible underground drainage for homeowners, buyers and property professionals across Farnham, Surrey and Hampshire. Sometimes called a drain survey or drainage survey, the inspection uses a CCTV camera to check the inside of a pipe without digging it up. You receive recorded footage, a mapped drainage layout, clear condition findings and practical next steps.

A CCTV drain survey uses camera inspections to record what can actually be seen inside accessible pipework - defects, blockages and damaged sections. It helps separate a one-off obstruction from a condition that needs repair, monitoring or further investigation.

Access and visibility determine what can be inspected. We record those limitations rather than presenting assumptions as findings.
We confirm the property, symptoms, known access points and who will rely on the report so the survey is scoped correctly.
An engineer accesses the drainage system, records the reachable runs and logs relevant observations and locations.
Footage and site information are checked and organised into a readable condition report and drainage layout.
You receive the findings, recommended priorities and a clear route forward if cleaning, repair or further investigation is needed.
The price of a CCTV drain survey depends on the size of the property, how many drain runs need inspecting, how easy the access points are to reach and what the report has to support - a straightforward condition check costs less than a homebuyer report a lender will rely on. Because we are based in Farnham, GU9 and GU10 visits carry no long travel charge.
You receive a fixed written quotation before any work is booked, covering the agreed scope, the deliverables and the price. If cleaning or jetting is needed before the camera can see clearly, we say so and agree it first rather than adding it afterwards.
