Direct answer
Trenchless repair can restore a suitable pipe with less excavation, commonly through relining or targeted methods. It still requires access, cleaning, diagnosis and a pipe condition that can accept the chosen system.
What can cause the problem or change the decision
| Possible factor | What to record safely |
|---|---|
| Cracked but lineable drain | Request before-and-after CCTV |
| Root entry at joints | Confirm the exact length and diameter |
| Access restricted by paving or landscaping | Ask how junctions will be treated |
| Local damage where excavation is disruptive | Compare warranty and exclusions |
