Pipe relining on the Northern Beaches
Updated October 2026
Pipe relining repairs a broken drain from the inside, without digging up your yard, driveway or bathroom floor. A resin-soaked liner is inserted into the damaged pipe, inflated against the walls and cured in place, creating a new structural pipe inside the old one. For ageing clay sewers and root-damaged drains on the Northern Beaches, it is often the lasting fix. Beaches Blocked Drains connects you with licensed local drain plumbers who reline pipes across the Beaches.
Why relining suits Northern Beaches homes
Much of the older housing on the Beaches, from Manly and Fairlight cottages to post-war homes in Narraweena and Forestville, runs on earthenware clay sewer pipes laid in short jointed sections. After decades of ground movement the joints open, and the big gums and figs push roots through every gap. By the time a drain is blocking repeatedly, the pipe often has cracked sections, displaced joints and multiple root entry points.
The traditional repair is to dig the pipe up and replace it. On the Beaches that can mean cutting through sandstone, excavating a steep garden, breaking up a driveway on a sloping block or lifting a tiled courtyard, then paying to reinstate all of it. Relining repairs the same pipe through existing access points. The liner seals every joint along its length, which also removes the entry points that let roots and sand in.
How pipe relining works
The licensed drain plumbers we work with follow a process along these lines:
1. Camera inspection. A CCTV inspection maps the damage: where it is, how long the affected section is, and whether the pipe is a candidate for relining. A pipe that has fully collapsed usually cannot be relined and needs excavation at that point.
2. Clean the pipe. High-pressure jetting and root cutting bring the pipe back to its full diameter, so the liner can bond properly.
3. Install the liner. A flexible liner saturated with epoxy resin is drawn or inverted into the pipe, then inflated with a bladder so it presses hard against the old pipe wall.
4. Cure and trim. The resin cures into a hard, jointless pipe within the old one. Junctions are reopened with a robotic cutter, and a final camera pass confirms the finished result.
Most residential relines are completed in a day, and you keep using your drains that evening.
What pipe relining costs on the Northern Beaches
Costs vary by job more than any other drain service, because they depend on the length, diameter, depth and access of the damaged section. As a guide, relining where tree roots have broken the pipe typically costs $3,000 to $8,000 or more. A short single-section patch sits at the lower end, and a full property line at the upper end or beyond.
Before that point, expect a CCTV inspection at typically $249 to $600, or $350 to $900 combined with jetting. Any relining quote should be based on camera footage of your actual pipe, and you should be shown that footage. If you are quoted a reline without an inspection, get a second opinion.
Relining versus digging and replacing
Neither option wins every time. Relining avoids excavation, preserves driveways, sandstone and landscaping, seals root entry points and is usually faster. Excavation can be cheaper for a shallow pipe under open lawn, and it is the only option where a pipe has collapsed flat or has a severe back-fall that a liner would simply follow. A plumber who offers both methods and shows you the footage is in the best position to recommend honestly.
One boundary note: Sydney Water owns the sewer mains, and you own the private drainage from your house to the connection point. Relining applies to your private line. If the camera shows the fault beyond your connection, report it to Sydney Water instead of paying for the repair.

Frequently asked questions
How much does pipe relining cost on the Northern Beaches?
Typically $3,000 to $8,000 or more where roots have broken the pipe, depending on the length, depth and access of the damaged section. A short patch costs less than a full line. Costs vary by job, so quotes should follow a camera inspection.
How long does pipe relining last?
Relined pipe is a hard, jointless structure inside the old pipe, and installers commonly design it for a service life of decades. Ask the plumber what warranty applies to your specific job.
Can every broken pipe be relined?
No. A pipe that has collapsed flat, or one with severe back-fall, usually needs excavation at that point. A CCTV inspection determines whether your pipe is a candidate.
Does relining stop tree roots for good?
In the relined section, yes. The liner seals the joints and cracks that roots were entering through. Roots can still enter other unrelined sections of the line, which the camera inspection will identify.
