An open bungalow flue with nothing on top, a wood-heater cowl that has worked loose, a gas terminal choked with leaves: Box Hill roofs carry every kind. FreshDuct fits and refixes caps, cowls, guards and spark arrestors from the roof, with a photo of the result.
Smell of damp ash from an unused fireplace? Rain is coming straight down an open flue.
Look along the rooflines of the older streets in Box Hill and plenty of bungalow chimneys are simply open at the top. When the fireplace was in daily use that hardly mattered, because the flue stayed warm and dry. Used a few times a winter, or not at all, the same flue takes rain onto the smoke shelf, damp spreads through the unlined brick, and the living room carries a faint smell of wet ash in humid weather.
The newer homes have the opposite problem: they already have a terminal, and it is the terminal that fails. A wood-heater cowl works loose on its bracket and rattles or lets rain in around the flue, and a gas terminal collects leaves and cobwebs until the appliance struggles to vent. We refix or replace the cowl and clear the gas terminal, and the gas appliance itself is handled by the licensed gas specialists we arrange.
For the open bungalow flue the fix is a rain cap with a bird guard, measured to the flue and fixed to the brick with fasteners that will not rust out, then sealed at the crown so the cap is not the next place water gets in. Where an open fire smokes into the room on a windy night, we test the draw and fit an anti-downdraught cowl only if the test says that is the cause.
Rain caps, bird guards, cowls and spark arrestors for Box Hill’s open bungalow flues and the terminals on newer wood-heater and gas flues.
Decades without a cap leaves a Box Hill bungalow flue damp and full of whatever the wind dropped in. A rain cap with a bird guard, sized on site and sealed to the crown, is a small job that stops the rot.
A cowl on a newer home’s wood-heater flue loosens with heat cycles and wind until it rattles and leaks. We refix it to the flue properly, or replace it with one that fits, and confirm the draw with it on.
A gas fire in a newer Box Hill home vents through a terminal that fills with leaves and webs. We clear and check the terminal so the flue vents freely; anything on the appliance goes to the licensed gas specialists we arrange.

A cap that is roughly the right size is the one that blows off. We measure the flue opening and the crown on the roof, choose a cap or cowl that fits it and the appliance below, and fix it with fasteners that suit the brick or the flue.
If we are already in Box Hill sweeping your flue, the cap can be measured, quoted and often fitted on the same visit. Either way you get a photo of it from the roof, square and sealed.

Because the flue is open at the top. Rain runs down the unlined brick onto the smoke shelf, where it soaks into decades of old soot, and the smell drifts into the room in humid weather. A rain cap with a bird guard keeps the water out; if it persists, the crown or flashing is letting water in as well.
Often, yes. If the cowl is sound and the flue top is undamaged it can be refixed and sealed properly from the roof. If the bracket has rusted or the cowl no longer matches the flue, a replacement that fits is the better spend, and we tell you which before quoting.
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.
