Chimney Installations in Melbourne — Fitted Properly.

The Chimney Side, Done Right

From the small but vital — a cap, cowl or spark arrestor to keep rain, birds and embers out — to the substantial — a flue liner and wood heater or fireplace installation — FreshDuct handles the chimney work that makes an install safe and effective.

Getting it right means matching the part or liner to your chimney and appliance, sealing the roof penetration, and keeping the correct clearances. We also manage gas fireplace work through licensed specialists, handling the flue and chimney side ourselves.

Done properly at install time, you avoid the classic problems — a smoky heater, a leaking cap, an unsafe flue — that are expensive to fix afterwards.

Our Installation Services

From caps to complete heater installs:

New fittings often follow a sweep or repair, so the chimney is clean and sound before anything is installed.

Draw, Heat and Safety Start at the Install

A correctly installed flue and cap is what lets a fireplace or heater do its job — creating the draught that pulls air through the fire, venting gases safely outside, and keeping rain and wildlife out. Cut corners on sizing, sealing or clearances and you get smoke, leaks, poor heat and a safety risk.

That’s why the chimney side is worth getting right at install time, by people who do it daily. A fitting installed properly simply works — and keeps working — rather than becoming a callback.

Sizing, Sealing and the Rules That Apply

The most common cause of a disappointing wood heater is a mismatched flue. A liner too large for the appliance cools the gases and weakens the draught; one too small chokes it. Manufacturers specify a flue size for a reason, and matching it is the difference between a heater that draws effortlessly and one that smokes.

Clearances and sealing matter just as much for safety. A wood heater and its flue must keep set distances from combustibles, and the flue must be supported and sealed where it passes through the roof — that’s what stops a flue fire reaching the structure and rain entering the cavity. In Victoria there are also rules around installation and where flues must terminate; we work to them, and point you to the Victorian wood heater rules.

Even the small installs reward care. A cap or cowl that’s the wrong size or simply jammed on is what works loose and rattles or blows off — whereas one matched and properly secured protects the flue quietly for years, and an anti-downdraft cowl can cure a chimney that smokes on windy days.

And where the appliance is gas, the certified work has to be done by a licensed gas fitter. Rather than pretend otherwise, we manage gas installs through licensed specialists and handle the chimney and flue ourselves — so you get one coordinated, correctly-licensed job.
