From bird-proof caps on old village chimneys to spark arrestors on wood heaters near the treed foothill blocks, FreshDuct fits and photographs the right terminal for each Berwick flue.
Wood heater on a treed Berwick block? A spark arrestor cowl keeps embers in the flue and leaves out.
The terminal on a Berwick flue is doing a different job depending on the house. On an older brick chimney near the village it is keeping rain, birds and leaf litter out of an open flue that may not have had a cap for decades. On an estate wood heater it is the cowl that came with the flue kit, which is fine until it corrodes, loses a fixing or starts letting wind push smoke back into the room.
Near the foothill fringe and on the treed blocks, the terminal has a third job: keeping embers in. A wood heater running hard on a windy night can send sparks out of an open cowl and onto dry leaf litter in the gutters. A spark arrestor cowl with mesh sized for the appliance stops that without choking the draw, and we test the draw with it fitted so the heater still burns cleanly.
Gas fires in the newer homes have their own terminal type, and we do not change it without the licensed gas specialists we arrange, but we do check it is clear, secure and not blocked by a nest. Every cap or cowl we fit is measured on site, matched to the flue and appliance, fixed and sealed from the roof and photographed so you can see it without climbing up.
Rain caps, bird guards, anti-downdraught cowls and spark arrestors fitted to Berwick's village chimneys and estate wood-heater flues.
Berwick homes on treed blocks toward the hills have gutters full of dry leaves under a hard-working wood heater. A spark arrestor cowl with the right mesh keeps embers in the flue, and we confirm it does not throttle the draw.
The cowl supplied with an estate flue kit is often thin metal that rusts at the fixings within a few winters. We replace it with a heavier cowl sized to the flue and fixed so it does not rattle or lift in wind.
Older Berwick chimneys near the village are frequently uncapped, and every autumn brings leaves and nesting birds down them. A cap with a bird guard closes the flue to weather and wildlife while leaving the draw unaffected.

We measure the flue, note whether it serves an open fire, a wood heater or a gas fire, and look at the block. A treed block gets a spark arrestor; a flue that smokes back gets an anti-downdraught cowl; an open brick flue gets a bird guard.
It is fixed and sealed from the roof, the draw is checked with the terminal on, and a photo of the finished cap comes with the job so you can see it without a ladder.

Yes, as long as we know the flue make and diameter. The arrestor is a terminal made for that system, so it locks on where the plain cowl came off. We size the mesh to the heater so it holds embers without throttling the draw, and clear it at each sweep because a treed block fills it with leaf litter.
Yes. The cowl that comes with many builder flue kits is light-gauge and corrodes at the fixings. We measure the flue, fit a heavier cowl that suits it, fix and seal it from the roof and photograph the result.
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.
