We get asked this a lot — “Should I reline or replace my pipes?” Fair question. If you’ve got blocked or damaged drains, both options can work, but one might save you time, money, and your garden. We’re here to break it down for you.

What’s pipe relining and how does it work?

Pipe relining is a no-dig method we use to fix cracked or leaking pipes from the inside.

Here’s how we do it:

• First, we inspect the pipe with a CCTV camera.
• Then, we insert a resin-soaked liner into the pipe.
• We cure it using hot water or steam.
• Once it sets, you’ve basically got a brand-new pipe inside the old one.

It’s perfect for tree root damage or cracks — especially if the rest of the pipe’s still in decent shape.

When do we recommend pipe replacement?

Sometimes the damage is too far gone for relining. If the pipe has collapsed, is completely corroded, or is made from outdated materials like clay or old galvanised steel, we’ll usually suggest a full replacement.

This means we remove the old pipe and install a new one — either by digging or using trenchless methods like pipe bursting. It takes more work, but sometimes there’s just no way around it.

What’s the cost difference between relining and replacement?

Here’s a rough guide (we always quote based on the job, but this gives you an idea):

Relining can seem pricey per metre, but you save heaps by avoiding digging up driveways or landscaping. That’s especially handy around here in the Northern Beaches — no one wants to rip up their backyard or their veggie patch.

How disruptive are these repairs?

We live here too, so we know how tricky it is working around gardens, tiles, or decks. Relining keeps things neat — your dog won’t even notice we’ve been there.

How long do the repairs last?

• Relined pipes: 25–50 years. That’s a solid run, especially if your system’s mostly in good nick.
• Replaced pipes: 50–100 years depending on materials like PVC or HDPE.

So, either way, you’re not dealing with this again anytime soon.

When do we suggest relining over replacing?

We usually go for relining if:

• The pipes are under concrete, driveways, or inside walls.
• The damage is localised (like cracks or root entry).
• You want it sorted quickly, without mess.

We’ve done a bunch of relining jobs across North Shore and Northern Beaches where the access was tight — saved heaps of hassle and money for the homeowners.

When is replacement the better option?

Replacement’s usually the go when:

• The pipe’s collapsed or completely corroded.
• Multiple sections are out of alignment or disintegrated.
• The original material’s too dodgy to keep.

We see this a fair bit in older homes, especially around the North Shore, where pipes haven’t been touched in decades.

Is relining better for the environment?

Yep. Relining is a cleaner process — no soil displacement, less transport, and almost zero waste. Replacement creates more mess and uses more resources. Not to get too greeny on you, but relining is the lighter footprint.

Can relining fix blocked drains?

Yes — and it’s often the best long-term fix.

If you’ve got tree roots in your pipes (very common around here), we:

1. Jet blast the blockage.
2. Inspect with a CCTV camera.
3. Reline the damaged section to stop roots coming back.

You can read more about that on our Blocked Drains Sydney page.
