Preston's unlined bungalow and period flues have soft mortar that rain should never reach, and its post-war homes have heater flues ending in whatever cap came with them. FreshDuct fits rain caps, bird guards and cowls, and tells you honestly when a cowl will not cure the smoke.
Fireplace smokes in Preston? Before buying a cowl, check whether the opening is the problem — we test both.
An open flue on a Preston bungalow or Edwardian home is a rain gauge for the chimney breast. Water runs down unlined brick, soaks the soft mortar, pools on the smoke shelf and turns old soot into a tarry sludge that smells through the room in humid weather. A rain cap stops it at the top, and on a chimney that has already had its mortar repointed it is the fitting that protects the repair.
Birds and possums are the other reason to cap. Inner-north flues that sit idle over summer collect nests, and a possum that finds a warm chimney in a Preston roof will keep coming back. We fit caps with bird guards to open fireplaces, and possum-proof terminals where one has already moved in, after clearing what is in the flue so the guard is not sealing a nest inside.
Cowls are where Preston needs honesty. A fireplace that smokes because its opening was widened will not be fixed by an anti-downdraught cowl. So before we fit one we test the draw and measure the opening against the flue; if the wind is the culprit we fit the cowl and test again, and if the opening is, we say so and explain the alternative. Post-war heater flues get a cowl matched to the pipe, not the nearest fit.

Soft interwar mortar in a Preston flue does not cope with rain running down it season after season. A rain cap keeps the flue dry from the top, which protects the brick, the smoke shelf and the plaster on the chimney breast below.
A possum in a Preston chimney is a noise at night and a smell by day, and it will return to a flue that stays open. We clear the flue, confirm it is empty and fit a guarded cap that keeps possums and birds out without choking the draw.
Post-war Preston homes run heaters up the old fireplace flue or a steel pipe, and the cowl on top is whatever came in the box, often rusted or the wrong size. We measure the pipe, fit a cowl matched to it and test the draw with it on.

We measure the flue or heater pipe on the roof, check the draw from the hearth and decide with you which terminal solves the actual problem: rain, animals, wind or none of them. The quote is firm before anything goes on.
Once it is fitted and sealed, we test the draw again with the fire lit and send you a roof photo of the finished cap, so you know it is on square without climbing a Preston bungalow roof yourself.

Yes. The cowl is a separate part on the top of the pipe. We measure the flue on the roof, fit a cowl matched to it with corrosion-resistant fixings, and check the flashing and the top section while we are there, because on a heater fitted decades ago they are usually the same age as the cowl.
Yes. We clear the flue and confirm nothing is still inside, sweep out the nest material, then fit a cap with a guard that keeps possums and birds out while the fireplace still draws. On a flue that is never used, a vented cap keeps it dry and empty.
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.
