Camera inspection: $300–$750
The first and non-negotiable step. Most operators credit it against the works if you proceed.
A cracked or root-damaged drain does not have to mean a trench through the garden. A resin liner is cured inside the existing pipe from an access point you already have, sealing every joint along the run, and the surface above is never touched.
Relining is a structural repair, not a cleaning method, and the distinction matters when you are comparing quotes. Jetting restores flow through a pipe that is still cracked. A liner restores the pipe.
That also means it is not always the answer. It cannot correct a run that has sagged or lost its fall, and it has nothing to line against where a section has collapsed. A camera survey separates those cases in about an hour, and the answer changes the cost by a multiple.
Older pockets and surrounding estates still run earthenware pipework that cracks as the Hills’ reactive clay soil moves through wet and dry spells.
Reactive clay soil moves with the seasons, lifting in the wet and shrinking back in a dry spell. Rigid drainage laid through it gets flexed every year, and the joints are where that movement is absorbed until they stop absorbing it.
It is the reason drainage faults on these soils cluster after a long dry followed by heavy rain. The pipe did not fail that week; it finished failing that week.
Water tracks along beams and slab falls, so the lot reporting the damage is often nowhere near the lot with the fault. Opening ceilings on a guess is how a small repair becomes three angry owners.
Camera and non-destructive location come first for exactly that reason. Once the defect is located and measured from a known point, the repair is a defined job and the liner goes in without exploratory demolition.
Norwest Business Park kitchens, cafes and office amenities push grease, food waste and heavy use through their lines, so blockages build fast without regular clearing.
For a shop, café or clinic the real cost of a drainage repair is rarely the invoice. It is the days the doors do not open, and an excavation through a floor or a car park is measured in days.
A liner is installed from an existing access point and cures in hours, which is why commercial work is so often scheduled overnight or across a single closed day. The trading interruption is usually the deciding factor, not the price per metre.
Properties on a slope often have long drainage runs, sometimes crossing the whole block to reach the main. The practical questions are where the inspection openings are and whether the liner can be drawn through in one length or needs a second access.
That is worth establishing before quoting. A single long run costs less per metre than the same distance broken into stages, and the difference is decided by access, not by the pipe.
On a clay line the barrel is usually fine. What has gone is the mortar or rubber ring at each joint, and there is one every few hundred millimetres, which is a great many small openings after sixty or eighty years in the ground.
That matters for the quote. You are not replacing a pipe, you are sealing a long series of joints, and a liner does the whole run at once rather than patching them one at a time.
A crack that opens in summer and closes in winter produces a fault that comes and goes, which is maddening to diagnose and very easy to dismiss as bad luck.
A liner is continuous through the affected length, so seasonal movement no longer has a joint to work on. On reactive ground that is the difference between a repair that lasts and one that reappears the next dry summer.

Seals one defect. Right where the rest of the run is sound and the ground is stable.
Length, diameter and how many branches need reinstating are what move the number inside that band.
Excavation is only half the cost. Replacing the driveway or garden above it is the other half.
