Root ingress
Fine roots find an open joint and grow into a mat that catches everything. Cut out with a jetter, then a patch liner seals the joint.
CCTV surveys
A recorded colour camera through every run, every defect graded with its distance from the chamber, and a written report in plain English with the stills that matter.

What we find
Fine roots find an open joint and grow into a mat that catches everything. Cut out with a jetter, then a patch liner seals the joint.
Ground movement shifts one pipe off the next, leaving a lip that catches paper and wipes. Minor ones are watched; bad ones are lined.
Old clay cracks under heavy vehicles and frost. A single crack takes a patch liner; many along a run take a full liner.
A section that has sunk holds standing water and silt. Shallow dips are jetted regularly; deep ones mean digging.
Kitchen fat cools and lines the pipe like a narrowing artery. Jetted out, and the cause at the sink explained.
The pipe has broken and the ground has come in. It cannot be lined; it has to be dug up and replaced, priced from the survey.
The report
Siân writes every report herself. It has a plan of the drain run with each chamber, the pipe sizes and materials, every defect with its distance, a grade and a still, and what we would do about it with a price. Insurers and buyers' solicitors take it as it is.

When a drain has blocked more than once, when you are buying an older house or one with trees near the drain, before building an extension over or near a drain, and for an insurance claim.
£165 for a typical house with report and footage; £230 if a run needs clearing first so the camera can get through. Surveys are booked in working hours.
We clear it first, then survey, because the camera cannot see through standing water and debris.
The phones are answered day and night. You get the price for the job and the time of day before we set off, an arrival window, and a text when we are fifteen minutes away.
