A drain that keeps blocking, a bad smell you cannot trace, or a house purchase that suddenly needs proof the pipework is sound. All three usually end at the same answer: a CCTV drain survey. If you are in Wiltshire and something is not right below ground, a camera inspection is the quickest way to see exactly what is going on without digging up your garden or driveway.

Here is what a CCTV drain survey actually involves, what it can find, and when it is worth booking one.

What is a CCTV drain survey?

A CCTV drain survey uses a small, high-definition waterproof camera fed through your drainage system on a flexible rod or crawler unit. The camera sends live footage back to the engineer, who records the whole run and notes anything unusual along the way. You get a written report and the footage to keep.

The point is simple. Instead of guessing where a problem is, we see it. That means you only pay for the repair the drain actually needs, not a full excavation on the off chance.

What a survey can find

Drainage faults hide well until they cause real trouble. A camera brings them into the open. A typical survey in a Wiltshire home might reveal:

Cracks and fractures

Small cracks let soil and water in and out, which over time leads to sinking ground and repeat blockages. Caught early, these are often fixed with a no-dig patch repair.

Root ingress

Tree and shrub roots are drawn to the moisture in drains. They push through joints and grow into thick mats that snag everything flowing past. A camera shows exactly where they have got in.

Displaced or open joints

Ground movement can pull pipe sections apart. Open joints let water escape and are a common entry point for rats.

Collapses

An old clay or pitch fibre pipe can deform or collapse completely. The survey pinpoints the collapse so the repair is targeted rather than a dig-and-hope job.

When you should book one

Not every blockage needs a survey. Sometimes a quick clear sorts it. But there are clear cases where a camera saves you money and stress:

• Your drain keeps blocking in the same spot despite being cleared.
• You are buying a property and want to know the drains are sound before you commit.
• Your insurer has asked for evidence of a drainage fault before a claim.
• You have noticed sinking patches in the lawn or driveway.
• You suspect rats are getting in through broken pipework.

Pre-purchase surveys are especially worth it. A drainage repair discovered after you move in can run into thousands, and the survey cost is small next to that.

No-dig repairs after the survey

One of the best things about starting with a camera is that most faults it finds can then be fixed without excavation. Patch repairs and full drain relining rebuild the pipe from the inside using a resin liner that cures hard. Your garden stays intact, the job is quicker, and the finished repair is guaranteed.

If a section has collapsed beyond relining, the survey still helps by showing precisely where to dig, so any excavation is as small as possible.

Why choose a local team

We are a family-run team of drainage engineers covering Dorset, Hampshire and Wiltshire, so we can usually get to you quickly rather than running everything from a distant depot. Every survey comes with a plain-English report, footage you can keep, and honest advice on whether you need a repair at all. There is no call-out fee, and we give you a fixed price before any work starts.
