Not every drain problem is a repair job, but when a CCTV survey shows a genuine crack, collapse, root damage or misaligned joint, we'll quote for the right fix rather than the most expensive one. Many repairs today use no-dig lining techniques that avoid tearing up a garden, driveway or floor.
Where excavation genuinely is needed — for a full collapse, for instance — we'll explain why before agreeing anything, and make good the area afterwards.
Ground movement on the valley hillsides and old clay pipes under Cardiff's terraces are behind most of the repairs we see. Patch lining fixes most cracks and open joints without digging, once the camera has found them.
Signs you need this
- A CCTV survey has identified a crack, collapse or root damage
- A drain that's settled, creating a dip where debris collects
- Recurring blockages at the same point in the same pipe run
- Visible subsidence near a known drain route
How we handle it
- 1 Confirm the exact damage and location with a CCTV survey
- 2 Recommend the least disruptive repair method that will actually last
- 3 Carry out the repair and make good afterwards
Questions people ask
Will you always need to dig up my garden?
No — patch lining and other no-dig techniques handle most cracks, joint damage and root intrusion. Full excavation is reserved for genuine collapses.
Who pays for a drain repair — me or Welsh Water?
It depends on whether the damaged section is a private drain or a shared/public sewer. We'll tell you honestly which applies once the CCTV survey shows exactly where the damage is.
