Water Going the Wrong Way? Read This First
A shower pooling at your feet, a gully surcharging in rain, a toilet that gurgles when the washing machine empties: these are early warnings worth acting on. Call (02) 9072 0520 and we will trace the fault before it reaches your floors. The full range of our work sits on the Mount Colah home page.
Why Drains Block Here More Than Most Suburbs
- The bushland fringe is the main offender Thick tree cover along the edge of Ku-ring-gai Chase National Park sends roots hunting moisture, and the ageing earthenware pipes under many local homes crack at the joints, handing roots a ready-made entry point.
- The terrain stretches every run Sewer and stormwater lines drop long, steep falls down the Hornsby Plateau's valleys, and silt plus debris settle at the low points where flow slows, building toward a blockage.
- Mid-century pipework is at the brittle stage Earthenware laid for the post-war homes here has reached the age where joints weep and shift in the reactive clay, which is why the same line can block repeatedly without a proper repair.
How it works
How We Clear Blocked Drains
Every job starts with diagnosis rather than guesswork, because clearing a line without knowing why it blocked is the fastest way to book the same callout twice. Our drainage team carries jetting, cutting and camera equipment on every van.
- 01
High-pressure water jetting
High-pressure water jetting scours the full inside of the pipe, cutting through stubborn grease, silt and root mass that a simple plunger or supermarket product never touches, and leaving the drain walls thoroughly clean rather than merely punched open.
- 02
Mechanical root cutting
Mechanical cutting heads grind intruding tree roots back to the pipe wall, restoring full flow immediately, though on clay lines around the bushland fringe we always recommend a camera check afterwards because roots will regrow toward any joint left vulnerable.
- 03
CCTV drain diagnosis
A waterproof camera travels the entire length of the line, showing exactly where the blockage sits, what caused it and what condition the pipe is in, so the quote you approve covers the real fix rather than a hopeful guess. See our CCTV drain inspections for the full detail.
- 04
Relining and permanent repair
Where a pipe has cracked or collapsed, trenchless relining installs a new structural lining inside the old drain, sealing every root entry point without digging up established gardens, paved paths or that sandstone outcrop your careful landscaping was built around. Our pipe relining page explains when relining beats excavation.
Storm Season and the Runoff Problem
- Summer storms overwhelm choked pits fast Heavy runoff sheets off the rocky sandstone slopes and surrounding bushland, and a stormwater pit already holding years of silt cannot absorb that volume, so water backs up across yards and driveways.
- Gully traps cop the overflow When the line surcharges, the lowest relief point in the system copes first, and an overflowing gully during downpour is the classic sign a stormwater run needs clearing before the next big cell hits.
- Prevention costs less than cleanup A cleared pit and a camera-checked line before storm season is a small job compared with pumping runoff out of a garage or drying out water-stained flooring after a summer deluge.
The Blockages We See Most
The drain that keeps coming back
A drain that clears and then blocks again within months almost always has roots regrowing through a cracked clay joint, and repeated clearing without repairing the joint just books you the same job again next wet season. Homes along Telopea Street and the gully streets off Foxglove Road sit where the tree cover is thickest.
Every fixture failing at once
When the toilet gurgles while the shower drains slowly and the laundry sink backs up together, the blockage sits in the shared sewer main downstream, and that combination needs professional attention before raw sewage surcharges back indoors.
The pit that overflows in rain
A stormwater pit that overflows every decent downpour usually holds years of silt and debris washed off steep sandstone slopes, and clearing it before summer storms arrive is far kinder on the wallet than pumping water out of a garage. Our stormwater team handles the full pit and line cleanup.
Why It Matters to Act Early
Sewage always finds the low point
A surcharging main backs up through the lowest fixture in the house, and flooring, skirting and stored belongings cost far more to restore than the blockage ever cost to clear.
Roots never stop growing
A joint that admits fine root hairs this winter admits a root ball next year, and every season of regrowth makes the eventual repair bigger, deeper and more expensive.
Clean drains protect the whole system
A line cleared properly and repaired where it is damaged keeps the rest of the household plumbing working as designed, instead of masking a fault that quietly worsens behind it.
How it works
How We Get It Done, Step by Step
- 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.
- 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.
- 03
Clear, verify and show you
The chosen clearing method runs through the line, whether that is jetting, cutting or relining, and a final camera pass confirms water now falls freely, with the footage shown to you before the crew packs up.
- 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 Mount Colah
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 Mount Colah 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.

Good questions, straight answers
Six Questions Mount Colah Locals Ask About Blocked Drains
What causes most blocked drains around here?
Tree roots entering cracked earthenware joints cause most blockages locally, because the suburb's bushland fringes and mid-century clay pipework give hungry roots exactly the moisture pathway they hunt for along ageing lines.
How much does it cost to clear a blocked drain?
The call out is free and you receive a single fixed written price covering the complete clear before any work starts, so the number you approve is the number on the invoice.
Can you tell what damaged the pipe without digging?
A CCTV camera inspection shows the blockage, the cracks and the root entry points along the whole run, which means the repair targets the exact fault instead of excavating on speculation.
Do you handle Sydney Water sewer main blockages?
Yes, our licensed plumbers manage the boundary and main side requirements under Sydney Water rules, and we handle the paperwork and coordination so the responsibility is sorted without you chasing the utility.
Why does my drain block every time it rains heavily?
Heavy runoff off the local sandstone slopes washes silt and debris into stormwater lines faster than they can clear, and a partially choked pit or pipe surcharges once the volume peaks during a downpour.
Is a gurgling toilet really urgent?
Gurgling means air is trapped by a blockage forming in the shared sewer line, and catching it early usually means a simple clear rather than an after-hours callout when the main surcharges.
