A straightforward residential pipe relining job often takes several hours and may be completed within one working day. Same-day completion depends on the pipe’s condition, access, cleaning required and the liner system’s curing requirements. Multiple sections or unexpected damage can extend the job over several days. A CCTV inspection is needed to confirm whether pipe relining is suitable before relying on an estimated schedule.
What the timeframe includes
The total timeframe usually covers:
- CCTV inspection: Checking the pipe’s condition, dimensions, junctions and access points.
- Cleaning: Removing roots, grease, scale and debris so the liner can bond correctly.
- Liner preparation: Measuring and preparing the liner for the relevant pipe section.
- Installation: Positioning the liner inside the existing pipe.
- Curing: Allowing the resin to harden using the specified curing method.
- Final CCTV inspection: Verifying the finished liner before the drain returns to service.
Curing time varies by resin, liner system, pipe dimensions, curing method and site conditions. A reliable completion estimate therefore requires a CCTV inspection and confirmation of the system being used.
Any required permissions can affect the overall project schedule even when the installation itself is quick. Confirm whether council or Sydney Water approval is needed before booking work.
What can make relining take longer?
The main causes of delays are:
- long, large-diameter or multiple pipe sections
- branches or junctions requiring separate liners
- substantial roots, grease, scale or compacted debris
- inadequate or difficult access
- severe deformation, collapse or unexpected damage
- site-specific curing requirements
- managing wastewater flow while connected fixtures remain unavailable.
If cleaning reveals conditions that prevent safe or effective relining, the plumber may need to stop and reassess the work. Severe collapse or unsuitable pipe condition may mean replacement or repiping is more appropriate.
When can the drain be used again?
Do not use affected toilets, sinks, showers or other connected fixtures during installation or curing. Use them again only after curing and final inspection are complete and the plumber confirms the drain is ready for service.
