Nobody wants to throw money at plumbing repairs every few years. If your pipes are cracked, leaking, or blocked by tree roots, you want a fix that actually lasts.
Pipe relining is marketed as a long-term, no-dig solution, but how long does it really last? Is it a permanent fix, or will you be back on the phone with a plumber in five years?
Let’s get straight to the facts.
Pipe Relining: What It Does and Why It Works
Pipe relining repairs damaged pipes from the inside by inserting a high-strength epoxy liner that hardens into a new, seamless, root-proof pipe.
Here’s the step-by-step breakdown:
✔ CCTV Inspection – A camera is sent down the pipe to see the exact damage. No guessing. No unnecessary work.
✔ High-Pressure Cleaning – The pipe is cleared of tree roots, grease, and debris.
✔ Liner Installation – A resin-coated liner is inserted and inflated to seal cracks and reinforce weak areas.
✔ Curing Process – Heat or UV light hardens the liner, creating a stronger-than-new pipe.This process avoids excavation, saves thousands in restoration costs, and provides long-term durability. But for how long?
So, How Long Does Pipe Relining Last?
Done correctly, pipe relining lasts 50 years or more. That’s not an estimate. That’s a tested, proven lifespan.
The epoxy resin used in pipe relining is engineered to:
✔ Withstand water pressure, corrosion, and heavy loads
✔ Remain seamless, preventing tree roots from penetrating
✔ Outlast many traditional pipe materials
The best part? A relined pipe often lasts longer than the original pipe ever did.
What Makes Pipe Relining So Durable?
- No Joints, No Weak Spots
Traditional pipes have joints that shift, crack, and allow tree roots to enter. A relined pipe is seamless from end to end, eliminating weak points. - Built to Resist Corrosion and Chemicals
Sydney’s water is full of minerals and treatment chemicals that eat away at old pipes. Epoxy liners have been designed to resist this damage for decades. - Stronger Than PVC or Clay
Clay pipes? They crack. PVC? It becomes brittle over time. Relined pipes? Stronger than both, with a smooth interior that prevents buildup and improves water flow. - Minimal External Damage
Shifting soil and heavy traffic stress pipes buried underground. Since pipe relining reinforces the existing pipe, it holds up under pressure better than many new installations.
Is Pipe Relining Stronger Than Traditional Pipe Replacement?
Homeowners often ask, “Should I replace my pipes instead?” The answer? Not unless you like throwing money away.
| Type of Pipe | Expected Lifespan | Common Issues |
| Relined Pipes | 50+ years | Seamless, root-resistant, corrosion-proof |
| PVC Pipes | 40 to 60 years | Can crack under pressure, sensitive to UV rays |
| Clay Pipes | 50 to 60 years | Prone to cracking, root intrusion |
| Cast Iron Pipes | 50 to 100 years | Corrodes over time, expensive to replace |
A properly relined pipe lasts as long as, if not longer than, traditional replacements. The difference? You’re not tearing up your driveway or spending a fortune on excavation.
What Affects the Lifespan of a Relined Pipe?
Even though pipe relining is built to last, a few things can impact how well it holds up:
✔ The Quality of the Resin Used – Not all epoxy resins are created equal. Cheap materials mean a short lifespan.
✔ The Experience of the Installer – Pipe relining isn’t DIY. A poor installation means early failure.
✔ The Condition of the Existing Pipe – Relining reinforces pipes, but if the original structure is completely collapsed, relining won’t work.
✔ External Pressure and Ground Movement – While relined pipes resist cracking, major soil shifts or construction damage can shorten their lifespan.
If you choose a qualified, experienced plumber who uses high-quality materials, your relined pipes will outlast most traditional replacements.
Is Pipe Relining Right for Your Home?
Pipe relining is a smart, long-term investment if you:
✔ Have cracked, leaking, or root-invaded pipes
✔ Want a solution that lasts 50+ years
✔ Need a fix without excavation or property damage
✔ Want a cost-effective alternative to full pipe replacement
If your pipes are completely collapsed, relining may not be an option. The best way to know? Book a CCTV pipe inspection.
