Plumbing, Drainage and Gas, all one local team
Plumbers and gas specialists in the one team, so nobody subcontracts the gas out and nobody waits on another schedule. Pick what's gone wrong and we'll tell you what it takes to fix it.
Emergency plumbing
Burst pipes, no water, sewage backing up, or a gas smell you don't like. We pick up after hours and tell you straight away whether it can wait.
Emergency plumbing
Hot water systems
Repairs, replacements and heat pump upgrades. Same-day changeovers where we can. A cold shower in Blackheath in July is its own emergency.
Hot water systems
Taps, toilets and repairs
Dripping taps, a toilet that runs all night, pressure that has dropped off. The jobs too small to bother with and too annoying to live with.
Taps, toilets and repairs
Rainwater tanks and bushfire supply
Tanks, pumps and mains changeover, and the static water supply that a fire truck can actually connect to when it matters.
Rainwater tanks and bushfire supply
Gas plumbing
Heaters, cooktops, gas hot water, BBQ points and compliance certificates. Licensed gasfitting, in a climate where your heater does the heavy lifting.
Gas plumbing
Blocked drains
Jetting, camera inspections and root cutting. Mountain blocks mean big trees over old clay pipes. We find the cause rather than clearing it once.
Blocked drains
Sewer and drainage installation
New drainage rather than unblocking old drainage. Sewer connections, stormwater lines, pits and the falls that make them work.
Sewer and drainage installation
Roof plumbing
Gutters, downpipes, flashings and the leak that only shows up in heavy rain. Roof plumbing is a licensed class in NSW, and it is on our licence.
Roof plumbing
Pipe locating
Underground pipes traced and marked on the surface before anyone puts a shovel or a post hole in the ground. You dig once, in the right place.
Pipe locating
Water service replacement
The pipe from the meter to the house. When it is old galvanised, it rusts from the inside and takes your pressure and your water quality with it.
Water service replacement
Bathroom renovations
Full rough-in and fit-off, working alongside your builder or tiler. Compliance handled, waterproofing coordinated, no surprises at handover.
Bathroom renovations
New homes and extensions
Rough-in and fit-off on new builds, extensions and secondary dwellings. Water, waste, gas and roof drainage, coordinated with your builder rather than around them.
New homes and extensions
Commercial plumbing and gas
Cafes, kitchens, accommodation and community buildings. The plumbing and gas, and the certificates your insurer, landlord or council asks for.

You live a kilometre up. Your plumbing knows it.
Katoomba averages a 2.6 °C minimum in July and runs about 7 °C colder than Sydney, with settled snow most years. Frost splits pipes, heaters get worked hard, and hot water systems fail in the exact week you need them most.
We service gas heaters before winter, lag exposed pipework, and carry the parts that fail up here. A plumber driving up from Penrith is guessing at a climate they don't live in.
Across the Upper Mountains, every day
Based in Katoomba, so the villages other firms treat as too far are a short run for us. Pick your suburb for what's specific to it.
Also covering Lawson, Hazelbrook, Bullaburra and Woodford. Call and ask.
Word of mouth since 2016

“My worst nightmare happened 10.15pm last night. Thankfully I was still awake when the pipe of my hydronic heater sprung a leak. Hot water began squirting out everywhere. I was on my own trying to find a bucket to hold the water. In desperation I rang Aidan Dunn Upper Mountains Emergency Plumber. He took my call straightaway and talked me through what to do. Aidan was so kind and understanding during the process and came to the rescue.”
“Being tradie myself I really appreciate job well done, in timely manner and reasonably priced. Once you experience Aidan and his team you never look back. Polite, on time, communicating well and finished job looks million bucks. On top of that the emergency response when you really need it is impressive - Saturday or Sunday doesn’t matter.”
“Needed a new gas oven installed after our previous one broke down. The whole process was simple - a couple of text messages and photos to Aidan, followed by installation the next day by James and Cameron. Great value, thoroughly recommended!”
The team on the other end of the phone
Call Upper Mountains Plumbing and Gas and you'll usually get Aidan on the phone. He leads the team, quotes the job, and picks up afterwards if something is not right. More than ten years in the trade, and on the mountain since 2016. Licensed for plumbing, drainage and gas, with Gasfitter and LP Gasfitter on the same ticket, and based in Katoomba, so our plumbers are already up here.
Call 0498 184 488Holiday lets, guesthouses and managed properties
The Blue Mountains took 2.9 million visitor nights in the year to March 2026. Every one of them needs hot water, a working toilet and safe gas. A fault means a refund and a one-star review.
Priority response for property managers and short-stay owners in Katoomba, Leura and Blackheath. Compliance checks between guests, and one number to call when a guest reports a problem at 9pm on a Saturday. Ask about a standing property agreement when you call.
The things people ask
What suburbs do you cover?
Katoomba, Leura, Blackheath, Wentworth Falls, Medlow Bath and Mount Victoria, and the smaller places in between them. We are based in Katoomba, so most of the Upper Mountains is a short drive rather than a trip up the highway. If you are not sure whether you are in range, ring and ask.
Are you licensed and insured?
Yes, and you can check it rather than take our word for it. Licence 479856C carries Plumber, Drainer, Gasfitter, LP Gasfitter and Roof Plumber, and it is on the NSW public register along with any compliance history. We are fully insured.
Are you gas specialists, or plumbers who do a bit of gas?
Gas is a licensed trade in its own right and we hold it in our own right. Licence 479856C carries Gasfitter and LP Gasfitter alongside Plumber, Drainer and Roof Plumber, so heaters, cooktops, gas hot water, LPG bottles and the compliance certificates are our work rather than a subcontractor's. Google lists us under Gasfitter and LPG conversion for the same reason.
Will I need another trade, or can you do the lot?
In most cases we can do the lot. The same licence covers the plumbing, the drainage, the gas and the roof plumbing, so a job that touches more than one of those is still one team and one price rather than three trades and three schedules.
How do I get a price?
Call and describe it, or send the form and we will call you back. For anything straightforward you will get a price before we start work. For anything we need to see first, we will tell you that honestly instead of guessing at a number over the phone.
Blocked, leaking, freezing or gasless?
Call Aidan. No call centre, no lead-selling middleman, no waiting on a form.
