A real person answers, day or night

When clearing a drain no longer holds, the pipe itself needs rebuilding

Some drains stop responding to the jetter because the fault is structural, not a blockage, and once a line has cracked, sagged or lost its grade, only a repair restores it. Call (02) 9072 0592.

Why the oldest drains under this suburb give out

Pipes as old as the streets

The area was settled from 1885, taking its name from the colonial businessman Thomas Sutcliffe Mort, and the earliest house drains went into the ground as earthenware during that early-1900s subdivision.

Joints, not walls, are the weak point

Those short clay and earthenware lengths were mortar-jointed by hand, so decades underground drop them out of line and shed the fall that carries waste.

No amount of clearing fixes a shape

Once a run has sagged into a belly or split along a joint, a jetter only buys weeks, so a rebuilt length becomes the honest end to it.

Drainage repairs and new lines we lay

The deepest end of our drainage work rebuilds pipe rather than clearing it, matching each fix to what the camera inspection actually shows underground before any trench is opened on the block:

Collapsed pipe replacement

Where a run has caved in or lost its grade completely, we excavate the failed section along older streets like Forest Road, lay fresh pipe to the correct fall, and end the repeat call-outs one broken line keeps quietly generating underground.

New drain installation

Adding a bathroom, a laundry or a granny flat means fresh waste lines, so we set out and lay new drainage to code with the right fall and access points, tying it cleanly into the main house drain heading out to the sewer.

No-dig relining

Rather than trench a mature garden, a cracked pipe that still holds its round can be rebuilt from within by curing a jointless relined sleeve inside the old one, which seals the fault and shuts out roots without lifting a single paver.

The ground here works against a rigid pipe

A ridge that swells and shrinks

The suburb sits on a rolling bed of reactive shale and clay that lifts in the wet and pulls back in the dry, levering rigid old joints apart.

Solid houses, tired services

Behind the double-brick and fibro frontages on streets like Victoria Avenue, the walls have aged far better than the earthenware beneath the garden, usually the first thing to move.

Movement finds the offset

A drain shifted even slightly no longer meets end to end, so silt catches, roots follow, and the fall to the main slowly disappears.

Common drainage faults we rebuild

Bellied lines

A sagging belly forms where the ground has dropped away beneath a length of pipe, so water and waste pool there instead of running on, and the standing sludge that collects breeds both the smell and the slow drain no clearing ever cures.

Cracked earthenware

Fine cracks spread through brittle early-1900s earthenware as it ages, letting groundwater seep in and thin roots feel their way out, until a hairline fault widens into a break that snags paper and grease into a full stoppage.

Lost fall

Sometimes a previous patch was laid dead flat or even slightly uphill, so waste never gains the speed it needs to clear, and the only lasting answer is relaying that section to a genuine grade rather than clearing it yet again.

Clearing debris from an excavated drain line

Why a failing drain is worth fixing properly

Putting a rebuild off rarely saves anything, because a structurally failed drain travels only one direction, and every month of patching adds cost to the repair that becomes unavoidable in the end:

  • Small faults grow into excavations A single cracked joint spreads as roots and ground movement widen it, so a short dig today can become a whole-of-yard replacement next year.
  • Escaping waste undermines the ground Water leaking from a broken line washes out the soil holding the pipe and the slab above, destabilising everything on top the longer it runs.
  • Repeat clearing is money into a dead pipe Jetting a collapsed line every few months only buys a short reprieve, while that same spend toward a rebuild settles the trouble for good.

How it works

Our drainage repair process, step by step

  1. 01

    Call and tell us

    Ring (02) 9072 0592 and describe what's happening, and a licensed plumber, not an answering machine, will tell you what it likely means, what to stop using, and when we can realistically be there.

  2. 02

    Quote before work

    Your plumber inspects the job properly, runs whatever diagnosis it genuinely needs, and hands you a single fixed written price covering the complete fix, with a $0 call out fee and nothing added afterwards.

  3. 03

    Dig or reline

    As soon as you accept, we open only the ground the footage marked, cut out the failed length and either bed new pipe to grade or draw a liner through, then reinstate the surface so the yard returns close to how it started.

  4. 04

    Backed for life

    Everything we complete is covered by our Lifetime Labour Warranty, the promise that outlasts the job itself: if it's not right, we come back. No questions. No cost.

Why choose Your Plumber Mortdale

Rebuilding a drain is invisible work you have to take on trust, so it helps to know exactly who is behind the spade:

Fixed prices, kept

Every job is priced upfront in plain writing before any work starts, the invoice always matches that number, and weekend or late-evening timing changes nothing, because overtime rates simply don't exist here.

Licensed and insured

Your Plumber Mortdale works under licence #275278C with full insurance behind every job, and the compliance certificates that protect your home's paperwork trail arrive with the invoice, without you ever needing to ask for them.

Lifetime Labour Warranty

Workmanship here is guaranteed for life under our Lifetime Labour Warranty rather than for a warranty card's fine-print window, which says more about how the work is done in the first place than any advertisement could.

Genuinely local response

We work these streets constantly rather than commuting in from across Sydney, so the van reaching you has usually just left a job nearby, stocked for the faults the local houses actually develop.

Where we work

Areas we service

We rebuild and install drainage across Penshurst, Oatley, Hurstville, Peakhurst and Allawah as well as our own blocks, and since the older St George streets all hide the same clay-and-earthenware runs, the van arrives already stocked with the fittings a rebuild calls for.

Good questions, straight answers

Drainage repair questions Mortdale locals ask

Can you repair a drain without digging up my whole yard?

Often yes, because a cracked or root-choked length can be relined from inside the pipe itself, and we dig up only the one section a camera confirms has collapsed or lost its fall.

How do you decide whether to repair or replace a pipe?

A camera pass down the line shows whether the pipe still holds its shape, which decides between a no-dig reline for a cracked run and a full dig-and-replace for a collapsed one.

Why do the old earthenware drains here keep failing?

The short mortar-jointed earthenware laid during the early-1900s subdivision grows brittle with age and shifts as the reactive clay ground swells and dries, so the joints drop out of line.

Will new drainage stop my blockages coming back?

When the cause is a broken or bellied pipe, relaying that section to the correct fall removes the trap debris and roots kept catching on, which ends the repeat blockages.

How long does a drainage repair take?

Most single-section repairs are done in one visit once the price is agreed, while a longer collapsed run under a driveway or garden takes a little more.

Do I get a warranty on drainage repair work?

Yes, every rebuild and new line we lay is covered by our Lifetime Labour Warranty, so any workmanship that later gives trouble is remedied on us rather than added to your invoice.
