The run is fine. It is where something joined it
On a lot of properties the relining conversation is about a length of pipe that has had enough. Here it usually is not, because the original drainage was laid in one program and it is consistent.
What is not consistent is what was cut into it later. A rear extension, a second bathroom, a laundry moved out into a new part of the house. In each case a new waste had to join the existing line, and how well that junction was formed is entirely down to whoever did it and how much they cared.
A badly formed junction leaves an edge, a lip, or a piece of the new pipe protruding into the old one. Every one of those collects. Material stalls at that point and builds from there, and the pipe either side can be in perfect condition while the same fixture blocks every winter.
The repair follows the diagnosis. The section is lined and the junction reinstated, cut back open from inside once the liner has cured, which leaves a clean entry where an obstruction used to be. Sometimes the junction can be dealt with more directly, and where a section has genuinely collapsed it needs replacing. The footage decides which, which is why we will not quote without it.
