A real person answers, day or night

Rain doesn't check the forecast before it finds your weak point first

A stormwater system only earns its keep during the one storm that actually tests it. Call (02) 9072 0520 and tell us what you're seeing, and a licensed plumber walks you through what matters most right now.

Working on a rooftop drainage outlet

No floodplain, but plenty of overland flow

  • No floodplain risk mapped here The steep falls toward Jewfish Bay, Neverfail Bay, Lime Kiln Bay, Oatley Bay and Gungah Bay mean stormwater races downhill fast in a heavy burst rather than pooling slowly like a river system.
  • Tidal influence stops at the water's edge Foreshore structures near the Oatley Park Baths feel the tide, while further up the hill the risk is entirely about how fast a downpour arrives, not how high the river runs.
  • The undulating ground amplifies every storm Streets around Mulga Road and River Road sit on genuinely different grades within a few blocks, so a stormwater pit sized correctly for one won't necessarily cope on the other.

Stormwater services we provide

Rain has to go somewhere, and when the built system can't cope fast enough it finds your yard, your garage or a neighbour's fence line instead, so every callout is sized to the actual downpour, not the average one:

Blocked pit clearing

We clear silted stormwater pits and grates that choke whenever leaf litter and runoff arrive together, restoring free flow before the next downpour tests the system, and checking the pit's fall to confirm it was sized correctly to begin with.

Box gutter repair

Box gutters overflowing into ceiling cavities get traced to their actual fault, whether that's a split membrane or an undersized outlet, then repaired properly so water leaves the roof the way it was designed to, not through a downstairs ceiling.

Surface drain installation

New surface drains and channel grates get positioned for the way water genuinely moves across your land rather than a textbook layout, carrying runoff away from foundations and paths on the steeper streets where it picks up speed once moving.

Absorption trench work

Where the ground genuinely allows it we build absorption trenches that let stormwater soak away safely instead of racing to the next pit, sized for the sandy pockets and shale rock this suburb's soil switches between from block to block.

Why the same storm hits two streets differently

  • Shale, rock and sand, block by block The ground shifts between shale, sandstone rock and sandy pockets within a short walk, so a stormwater fix that works well on one street can underperform on the very next one.
  • Older streets carry older stormwater too Pits and pipework installed decades ago rarely match the paved, extended-roof footprint of a renovated modern home, so capacity gets outgrown quietly until one big storm proves it.
  • Downhill blocks inherit everyone's runoff Properties lower on the slope collect stormwater from every yard above them, worth knowing before assuming a flooded corner is entirely your own drainage system's fault.

Common stormwater problems we fix

Yard flooding in storms

A yard that floods every time it rains hard usually means the stormwater line downstream is undersized or silted rather than genuinely overwhelmed by the weather, and once we trace the actual bottleneck the fix is often smaller than expected.

Overflowing gutters and downpipes

Gutters spilling over in a downpour often trace back to a blocked downpipe or the underground line it feeds rather than the gutter itself, so we check the whole run from roof to outlet before replacing anything that isn't broken.

Why stormwater problems don't fix themselves

Water finds the lowest point every single time, and on sloping ground that point is usually a doorway, a garage floor or a retaining wall footing, which is why a small overflow rarely stays small for long:

  • Structural damage builds quietly Water pooling against a foundation or retaining wall for one season can undermine it over several, and the repair bill grows every year the drainage stays wrong.
  • A wet yard becomes a wet house Overland flow that isn't captured properly eventually finds a doorway or a subfloor vent, turning an outdoor nuisance into an indoor one.
  • Undersized pits fail when you need them most The storm that tests your stormwater hardest is always the heaviest one, and that's the worst possible moment to discover a pit was never sized for it.

How it works

How we fix stormwater problems, step by step

  1. 01

    Call and tell us

    Ring (02) 9072 0520 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

    Clear or rebuild

    We clear, reline or rebuild whichever section the inspection actually points to, sized correctly for the block's genuine fall rather than a standard fitting, matching the proper system to whatever the next heavy storm genuinely throws at it.

  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 Oatley

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 Oatley 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

Stormwater jobs take us through Mortdale, Hurstville Grove, Connells Point, Peakhurst Heights and Penshurst just as often as Oatley's own hills and gutters, sizing every fix to the slope actually in front of us instead of a one-size-fits-all pipe.

Good questions, straight answers

Stormwater questions from Oatley locals

What determines the price of a stormwater repair?

It depends entirely on what the inspection finds, from a single silted pit to a full undersized line, which is why tracing the fault, diagnosing it and writing the quote cost you nothing at all.

How quickly can you fix flooding during a storm?

Active flooding jumps to the front of the queue, and a licensed plumber talks you through what to do while the van is already on its way, not sometime later in the day.

How do you find what's actually causing the flooding?

We trace the whole stormwater run from the highest point on the block down to the outlet, checking every pit and pipe along the way, rather than guessing from where the puddle happens to sit.

What's the difference between stormwater and sewer drainage?

Stormwater carries rain off your roof and land to the street system, sewer carries household waste to the main, and treating them as the same system is the most common mistake we see.

Why does stormwater behave differently across this suburb's streets?

The soil underfoot changes from one street to the next, and combined with steep falls toward the bays, two properties close together can flood in completely different ways during the very same storm.

Is stormwater work covered if the same problem happens again?

Yes. Every stormwater repair is guaranteed for life, so if a fault we're responsible for shows up again in a future storm, the redo is on us rather than on you.
