The clay pots on a Fitzroy terrace stack sit high above the parapet and mostly open to the sky. FreshDuct fits pot-mounted caps, bird guards and anti-downdraught cowls to Victorian terrace flues, with the right pot confirmed before anything goes on.
Fireplace smoking back in a Fitzroy terrace? Wind tumbling off the neighbouring stacks and rooflines is the usual cause, and a cowl usually fixes it.
Look along any Fitzroy roofline and you will see rows of clay pots on the parapet stacks, most of them wide open. Each one tops a tall, narrow, unlined flue, so the rain that goes in has a long way to fall and plenty of soft mortar to soak into on the way down. Birds find an open pot on a shared stack quickly, and a nest a few metres down a flue you rarely use goes unnoticed until the smell arrives.
Capping a terrace pot is a matter of the right pot and the right fitting. On a stack that carries flues from two houses, the pot has to be matched to your fireplace first, which we do with a camera and a smoke check. Then a cap sized to the pot is clamped on, with a bird guard on the flues you use and a vented cap on the ones you do not, so water and nests stay out while the flue still breathes.
Downdraught is the other terrace complaint. Stacks that stand close together, with taller buildings and rooflines around them, give the wind plenty to eddy off, and an open pot on the sheltered side gets smoke pushed back down it. An anti-downdraught cowl on that pot is the usual cure, and we test the fire with the cowl fitted rather than assuming it has worked. Photos of every fitted cap come from the roof.

On a parapet stack carrying both houses’ flues, capping the wrong pot is easy and helps nobody. We match your fireplace to its pot with a camera and smoke check before anything is fitted, and leave the neighbour’s pots exactly as we found them.
Terrace pots that have stood open for years are usually part-filled with nesting material. We clear what we can reach and check the flue below on camera before fitting a cap with a bird guard, so nothing is sealed in above a fireplace you may light later.
A row of heritage terraces is not the place for an oversized galvanised hood. We fit caps and cowls that clamp neatly onto the original clay pot and read as part of the stack from the street, rather than removing the pot to fit a modern terminal.

When a Fitzroy fireplace smokes on windy evenings, the cause is usually air tumbling off a taller neighbour or the next stack along and dropping down an open pot. An anti-downdraught cowl turns with the wind and keeps the draw going up.
We light the fire with the cowl fitted and watch the draw before we call it fixed. If the flue itself is the problem, blocked or too cold to draw, we say so rather than sell a cowl that will not help.

Usually. Terrace stacks sit close to taller neighbours and rooflines, and wind eddying off them pushes smoke back down an open pot. An anti-downdraught cowl on that pot is the normal fix, and we test the draw with the fire lit before we leave.
No. Caps and cowls clamp onto the existing pot, so the original stays in place and the stack looks the same from the street. We size the cap to the pot on site, fit it from the roof and photograph it in place for you.
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.
