Your Reliable Local Plumber in Cromer — Collis Bros Plumbing
Cromer is a relaxed, well-established suburb that sits comfortably between the coast and the plateau, the kind of place where people raise families, renovate homes and generally just get on with life. When plumbing problems interrupt that, people want a reliable local plumber who doesn’t complicate things unnecessarily.
That’s what Collis Bros Plumbing is. We’re a family plumbing business that’s been working across the Northern Beaches for years, and we work in Cromer regularly. We show up when we say we will, we diagnose problems correctly, we quote honestly and we carry out work to a standard we’re proud of. Simple as that.


Cromer’s Homes and Their Plumbing Realities
Cromer’s housing is fairly consistent in character, predominantly detached brick homes built from the 1960s through to the 1980s, often on well-sized blocks with good gardens, close to schools and parks. It’s a comfortable suburb to live in, and the homes reflect the care their owners put into them.
From a plumbing perspective, the consistent construction era means there’s a fairly predictable set of issues that come up regularly. Original clay drain lines are reaching the end of their structural life in many properties. Hot water systems installed during the last major round of suburb-wide upgrades are now due for replacement again. Bathroom renovations are popular as owners update homes that are forty-plus years old.
We see all of this regularly, and that familiarity with Cromer’s housing stock makes us genuinely efficient to work with here, we know what we’re likely to find before we even open the inspection hatch.
Plumbing Services Available in Cromer

Leak Detection and Plumbing Repairs
Hidden leaks are a particular concern in Cromer’s older, long-held 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 Cromer 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 Cromer 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 a heavy downpour, 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 Cromer: Given the age of much of Cromer’s underground plumbing, tree root intrusion into older clay and cast-iron pipes is one of the more frequent culprits we come across, particularly on the suburb’s well-established, tree-lined streets. 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 Cromer
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 Cromer 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 Cromer homes 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 Cromer homes, 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 Cromer, 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 Cromer 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
Cromer’s blend of established family homes and ongoing renovations means kitchen and bathroom plumbing makes up a significant chunk of our work in the suburb. Whether you’re refreshing a dated 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 Cromer 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 and other trades to keep renovation projects moving and make sure the plumbing matches the standard the rest of the build is aiming for.
Plumbing Health Maintenance for Cromer Properties
For Cromer homeowners who want to stay ahead of plumbing problems rather than react to them, we offer comprehensive plumbing health checks, a thorough inspection of all accessible plumbing with a clear, plain-language report on findings and recommendations.
These visits are particularly valuable for homeowners who haven’t had a professional look at their plumbing in years, or who are preparing a property for sale or long-term tenancy. We’ll identify what’s worn, what’s at risk and what’s in good shape, so you can make informed decisions about what to address and when.
