Collis Bros Plumbing
Reliable Plumbing Solutions for Cremorne
From strata buildings and apartments, we deliver reliable plumbing solutions tailored to Cremorne properties.
Strata, Apartment, Heritage Home — Collis Bros Plumbing Does It All
Cremorne is one of those suburbs that packs a remarkable variety of property types into a relatively compact area. Freestanding federation homes and brick interwar houses sit alongside 1960s apartment blocks, modern strata buildings and everything in between. That diversity of property types means plumbing demands here span an unusually wide range, and the plumber you call needs to be capable across all of them.
Collis Bros Plumbing is. We work across residential homes, strata properties, period apartment buildings and commercial tenancies throughout Cremorne and the lower North Shore. We’re licensed, experienced and genuinely reliable, the kind of plumbing business that people recommend to their neighbours.Collis Bros Plumbing has been part of the Northern Beaches community for years, and Forestville is a suburb we genuinely enjoy working in. We’re called here for everything from blocked drains and hot water failures to full bathroom renovations, and we bring the same professional, no-nonsense approach to every job. Local knowledge, honest communication, and work you can rely on.


Plumbing Across Cremorne’s Diverse Property Mix
Cremorne’s older apartment buildings present a distinct set of plumbing challenges. Cast-iron drainage stacks from the 1950s and 60s, shared drain lines between multiple units, and building-wide infrastructure that’s been patched and modified over decades, all of these create situations that require a plumber who understands apartment-building plumbing, not just residential house plumbing.
For Cremorne’s freestanding homes, the challenges shift toward the heritage end: older pipes in difficult-to-access locations, bathroom and kitchen layouts that weren’t designed with modern fixtures in mind, and the ongoing work of maintaining century-old infrastructure.
For strata managers and property managers working in Cremorne, we offer the added benefit of fast response times, documentation of all work carried out and clear communication about what’s been done and what may be coming. We understand the reporting requirements of strata management and make that process as straightforward as possible.
Plumbing Across Cremorne’s Diverse Property Mix

Leak Detection and Plumbing Repairs
Hidden leaks are a particular concern in Cremorne’s older apartment blocks and heritage homes, where ageing pipework can be leaking quietly behind walls, under floors or beneath the slab for months before anyone notices. Watch for warning signs such as damp patches, bubbling paint, soft or spongy flooring, or a water bill that’s crept up without explanation. Our plumbers use proper leak detection equipment to pinpoint the source accurately, without tearing your property apart to find it.
Leak repairs we handle across Cremorne include leaking taps and mixers, cracked or burst pipes, toilet leaks, shower leaks, under-bench plumbing issues, damaged water lines and outdoor plumbing leaks.
If you think you’ve got a leak somewhere in your Cremorne property, get it checked sooner rather than later. The earlier we find it, the less it costs to fix.

Blocked Drains and Drainage Solutions
A blocked drain doesn’t wait for a convenient time. Whether it’s a kitchen sink refusing to empty, a bathroom backing up, or stormwater overwhelmed after heavy rainfall, Collis Bros Plumbing responds fast and gets your drainage moving again. Rather than just punching through the blockage, we work out why it happened so it doesn’t keep coming back.
We use high-pressure water jetting and CCTV drain cameras to locate blockages and check the condition of the pipework underground. That gives us an accurate picture of what’s really going on, so the fix we recommend actually solves the problem long-term.
Common Causes of Blocked Drains in Cremorne: Given the age of much of Cremorne’s underground plumbing, tree root intrusion into older clay and cast-iron pipes is one of the more frequent culprits we come across, particularly around the suburb’s mature streetscapes. Beyond that, we regularly deal with grease and soap build-up, hair clogging bathroom drains, wipes and foreign objects flushed down toilets, and structural damage in ageing drain lines.

Toilet Repairs and Installations in Cremorne
Few plumbing issues disrupt a household faster than a toilet problem. A cistern that won’t stop running can waste hundreds of litres a day and quietly inflate your water bill. A blocked or leaking toilet needs sorting straight away for obvious reasons. Our plumbers work across all toilet systems and types and, in most cases, can diagnose and fix the issue in a single visit.
Toilet services we provide in Cremorne include running or continuously cycling toilets, blocked toilets, leaking cisterns and pan connections, full toilet suite replacements, new toilet installations and water-efficient dual-flush upgrades.
Plenty of older toilet suites in Cremorne’s established homes and apartment buildings use far more water than they need to. If yours is outdated or unreliable, switching it out can improve performance and trim your household’s water use at the same time.

Tap and Fixture Installations
Taps and fixtures get used constantly, and it shows. Once they start leaking, wearing down or clashing with a freshly renovated kitchen or bathroom, it’s time for a swap. Collis Bros Plumbing installs and repairs the full spectrum of tapware and fixtures for Cremorne properties, from simple, no-fuss replacements to higher-end finishes for renovation projects.
We work with kitchen and bathroom mixers, basin and sink tapware, showerheads, laundry tubs and outdoor taps. Bring your own fixtures or let us recommend and source them, either way, the installation will be done properly and the finished result will look and work the way it should.

Hot Water System Plumbing
Not much affects everyday comfort like a hot water system that’s stopped pulling its weight. Collis Bros Plumbing services and installs hot water systems throughout Cremorne, getting households and tenants back to reliable hot water as quickly as possible. If it’s repairable, we’ll repair it. If it’s reached the end of the line, we’ll give you a straight assessment and a competitive quote for a replacement.
Hot water services we offer in Cremorne include hot water system fault diagnosis and repair, pipe and valve replacements, pressure and temperature relief valve servicing, system upgrades for improved efficiency, and full hot water system replacements and new installations.

Kitchen and Bathroom Plumbing
Cremorne’s mix of heritage homes, apartment renovations and premium residential developments means kitchen and bathroom plumbing makes up a significant chunk of our work in the suburb. Whether you’re modernising a period bathroom, fitting out a new kitchen or updating a laundry, our team delivers precise plumbing that fits seamlessly into the bigger renovation.
Kitchen and bathroom plumbing services in Cremorne include sink and basin installations, dishwasher and appliance plumbing connections, shower and bath rough-in and fitout, vanity and tapware installation, waste, overflow and trap connections, and pipe relocation and rerouting.
We coordinate with builders, designers, strata managers and other trades to keep renovation projects moving and make sure the plumbing matches the standard the rest of the build is aiming for.
Scheduled Maintenance for Strata and Property Managers
For strata committees and property managers responsible for buildings in Cremorne, we offer scheduled preventative maintenance programs, periodic inspections of common-area plumbing, hot water systems, drains and pipe infrastructure, with detailed written reports after each visit.
Proactive maintenance reduces emergency callouts, extends the lifespan of building plumbing infrastructure, and helps strata committees plan expenditure rather than react to failures. We can also provide compliance certificates for relevant plumbing work, and we’re experienced with the documentation requirements of strata management.
