Between the bay breeze and a winter of wood-heater smoke, the terminal on a Cheltenham flue has a hard life. FreshDuct fits corrosion-resistant cowls to heater flues and caps to open brick chimneys, fixed from the roof and photographed.
Cowl on a Cheltenham heater flue rusting at the base? Replace it before it sheds into the flue or lets go in a storm.
Cheltenham sits far enough from the beach that people forget the salt, and close enough that a galvanised cowl eventually reminds them. The cowl on a wood-heater flue is a thin spun-metal part in the most exposed spot on the house, and once the coating fails it rusts through at the base, seizes if it rotates, and finally lets go, leaving the flue open. Open brick chimneys with no cap at all are common too, and take the weather straight down onto the firebox.
The fix is the right terminal in the right material. Heater flues get a cowl in stainless or a coated corrosion-resistant finish, sized to the flue diameter and fixed so it cannot work loose; open chimneys get a rain cap with a bird guard, sealed to the top of the stack. Where a fire smokes back on a bay breeze, an anti-downdraught cowl replaces the standard one and we check the draw with the fire lit before leaving.
Most of the work is done from the roof on ordinary tiled pitches, and it is often combined with a sweep if the rods are already out and the old cowl is obviously past it. Every fitted cap or cowl is photographed from the roof before we come down, so you can see it is square, sealed and the right size without going up yourself, and the photo stays with the job record.
Corrosion-resistant cowls for wood-heater flues, rain caps and bird guards for open chimneys, and anti-downdraught cowls for breezy bayside conditions, fitted and photographed.
Galvanised cowls fail in Cheltenham long before they would inland, rusting at the base and the fixings. Stainless or coated corrosion-resistant terminals cost a little more and last far longer on a roof this close to the bay, which is why they are what we fit.
A cowl on a hard-used heater flue collects creosote and rust scale in its mesh and louvres, which throttles the draw and makes the heater smoulder. We clean or replace the cowl during a sweep, and fit one that can be cleaned again next year.
Wind coming off the bay can push smoke back down a Cheltenham flue on gusty evenings. A rotating or fixed anti-downdraught cowl steadies the draw, and we confirm it with the fire lit rather than promising it will work and leaving.
Real photos from Melbourne jobs — not stock, not staged.
We measure the flue diameter or the stack opening on site, choose a terminal to suit a heater or an open fire and the salt exposure, and fix it from the roof so it stays put in a bayside blow rather than ending up in the garden.
A photo of the finished cowl or cap comes with the job. If the old one was still sound and just needed cleaning, we tell you that instead of selling you a new one you did not need.

A galvanised one, not long; the base and the fixings rust in the bay air and it eventually lets go. A stainless or coated corrosion-resistant cowl lasts far longer for a modest extra cost, which is why it is the only kind we recommend this close to the water.
Often. A clogged or rusted cowl throttles the draw, and a standard cowl lets a bay breeze push smoke back down. We check the cowl for creosote and corrosion first, and fit an anti-downdraught type if the draw is the issue, testing it with the fire lit.
An open flue lets rain, leaves and birds straight in. A cap keeps the flue dry, keeps nests out and, on a wood heater, a spark arrestor stops embers leaving the flue.
Usually a downdraught — wind pushing back down the flue. An anti-downdraught cowl is the normal fix; we confirm the draw with a test before and after.
Yes. If we are on the roof for a sweep and the flue needs a cap, we can quote it on the spot and fit it the same visit where we have the right size.
