Water moves fast on a slope like this

Runoff heading downhill during heavy rain arrives with real force. Where a system's undersized or partially blocked, that shows up as pooling near a driveway, a retaining wall, or the low side of the house.

Getting the fall and pipe sizing right the first time avoids water finding its own way through a garden bed instead.

  • New installations for knockdown rebuilds Designed to meet council-compliant drainage requirements from the plans stage
  • Upgrades to undersized older systems Resizing or rerouting sections that can't keep up with today's runoff
  • Repairs to damaged or root-affected lines Particularly near the Explosives Reserve bushland boundary
  • Clearing blocked stormwater lines Jetted and camera-checked the same as a sewer line would be

How it works

How it works

  1. 01

    Call and tell us

    Ring (02) 9072 0519 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

    Built for the real fall

    The slope's actual grade drives the design, not a standard assumption.

  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 Castle Cove

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 Castle Cove 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 drainage work also covers Middle Cove, Killarney Heights, Willoughby East, Castlecrag and North Willoughby.

Good questions, straight answers

Stormwater questions from locals

Why does stormwater drainage matter more on a block like this?

Real elevation change toward Middle Harbour means water moves fast during heavy rain, and a system has to be built for that actual fall.

What causes pooling near a driveway or retaining wall after rain?

Usually an undersized or blocked stormwater line that can't keep pace with runoff coming down the slope.

Do knockdown rebuilds need council-compliant stormwater plans?

Yes, and we design and install to meet those requirements properly rather than as an afterthought.

Can an old stormwater system be upgraded without a full rebuild?

Often, yes, sections get replaced or resized where the existing system genuinely can't cope.

Are blocked stormwater drains linked to bushland root intrusion too?

They can be, roots from the Explosives Reserve boundary affect stormwater lines the same way they affect sewer lines.

How quickly can a stormwater issue be assessed?

Usually within a day, sooner where water's actively pooling against the house.
