A wide bungalow pot and a slim terrace pot need different caps, and Northcote has plenty of both. FreshDuct fits rain caps, bird guards and anti-downdraught cowls sized to the flue, sealed from the roof and photographed.
Northcote fireplace smoking on windy nights? A cowl matched to the pot usually settles it.
Look along a Northcote roofline and you will see the two chimney types side by side: rows of slim pots on the Victorian terrace stacks toward the flat, and broad single flues on the Edwardian and bungalow chimneys up the hill. Very few of either have anything over them. That leaves the flue open to rain, to leaves, and to the birds that treat an uncapped pot as a ready-made nesting hole.
Sizing is the whole job. A cap made for a narrow terrace pot will not seat on a wide bungalow flue, and a large cap forced onto a slim pot chokes the draw and makes the fire smoke. We measure the pot on the roof, choose a cap with a guard that lets the flue breathe freely, and fix it so it stays square through a winter of wind.
Houses on the rise toward High Street stand more open to the weather than those down on the flat, and that is where a fireplace is most likely to smoke on a windy night. An anti-downdraught cowl is the usual answer; we fit it, light a test and watch the draw before calling it fixed. Every cap is photographed from the roof so you can see it without a ladder.
Rain caps, bird guards and anti-downdraught cowls measured to the pot, for the slim terrace stacks and wide bungalow flues of Northcote.
The single broad flue on a Northcote California bungalow lets in far more rain than a slim terrace pot, and it ends up as a wet smoke shelf and a musty front room. A rain cap sized to the wider opening keeps the flue dry without slowing the draw.
Chimneys up the Northcote hill sit higher in the wind than those near the flat, and a gust across the pot can push smoke back into the room. We fit an anti-downdraught cowl to the flue that smokes and test the draw with it on before we leave.
A row of original pots is part of what makes a Northcote terrace look right, and a bright steel cowl on every one spoils it. We fit low caps in a quiet finish to the flues in use and vented caps to the rest, so the pots stay.

Fitting a cowl and leaving is not a fix. On a Northcote flue we light a test after the cowl goes on and watch that the smoke goes up and stays up, because a downdraught that survives the cowl usually means the pot or the flue needs another look.
Caps and cowls are quoted firm once the pot is measured, fitted from the roof with harness work where the pitch calls for it, and photographed before we come down so you can see the finished job.

The working flue needs a proper cap with a bird guard. The three idle flues should get vented caps rather than being left open or sealed shut, so rain and birds stay out but the old brick can still breathe. All four are fitted and photographed from the roof in one visit.
Not if it is sized to the flue. A wide bungalow flue needs a cap with an opening to match, so the smoke leaves as freely as it did with the pot open. We measure first, fit a cap that suits the flue, and test the draw with the cap on.
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.
