• I fit a variety of chimney cowls and chimney pots. I will only fit a cowl I think is suitable for your particular application be it solid fuel, gas, oil or a situation where a downdraft may occur.

  • Chimney pots can be supplied in a variety of sizes. Ask me about the building regulations in regulation to the bore size of a chimney pot

  • Really a pre fit survey is required to determine the type of cowl that is suitable.

  • I always try to fit a high quality cowl; I think if you are paying for someone to go on your roof to fit a cowl then it is false economy to fit a cheap poor quality cowl which may not last long. On numerous occasions I have also had calls from customers who have in the past had a cone top or balloon guard fitted by some one else only to find it on the lawn a few years later, dislodged by a bird or the wind. 

  • I usually do not fit a cowl when I am sweeping the chimney. I need at least one other man to go on the roof and a set of ladders (obviously). Also I need to check the access for the ladders.

VERY IMPOTANT.   THE COWLS ABOVE ARE NOT TO BE USED ON CHIMNEYS WITH LIVE FIRES. THEY ARE A CARBON MONOXIDE RISK.

CHIMNEY COWLS AND POTS, SALES AND FITTING

We also fit a stainless steel anti downdraft cowl that is particularly heavily shrouded which has the additional of reducing water ingress. Obviously these cowls are more expensive than the other anti downdraft cowls we fit. These cowls are also strap fix

STAINLESS STEEL ANTI DOWNDRAFT COWLS.

  • Older properties often have a fireplace in every room and now most of these fireplaces have been removed and the builders opening bricked/ blocked up. If the job was done properly a vent would have been fitted at the bottom of the flu to allow air to circulate through the chimney. without this vent you can experience falling damp.

  • Besides taking care of the flue by putting a vent in you should ideally take care of the top of the chimney. This is where the ventilation terminal comes in. It allows a reduced amount of air to flow through the flue to keep it dry but prevents water getting in through the chimney pot. Every year a surprisingly large amount of water gets into a uk chimney. In the winter this water can freeze leading to structural problems in the chimney.

  • Of course if you have a bricked up chimney and a birds nests in the flue then it is impossible to remove the nest, since it has to be removed by sweeping it out from the bottom. the nest will prevent air flow through the flue and lead to damp problems. the largest nest I have removed filled a previously empty mini skip, another filled 8 bin sacks!!

  • An additional benefit of fitting a ventilation terminal is that they can significantly reduce heat loss from the house due excessive air flow through the chimney.

  • NOTE SOME SO CALLED CHIMNEY CAPS DO NOT ALLOW AIR TO FLOW, OURS DO!

  • Unlike a lot of ventilation terminals the ones I use do not require sealing with mastic. Over time the mastic will deteriorate causing ingress of water as it tracks down the body of the cowl.

  • The ventilation cowls we fit are basically maintenance free can be easily removed should the flue need to be brought back into use in the future.

  • Bird guards that are suitable for gas are not suitable for solid fuel and vice versa, this is because the rules concerning mesh size are different for each situation.

  • Our cowls are generally held in place with a stainless steel strap which I turn helps hold the chimney pot in together by putting the pot into compression. So it can help stop cracks in the pot opening up.

  • In addition cowls are fitted above solid fuel appliances should be either painted or manufactured from stainless steel because of the corrosive nature of the products of combustion.

  • Most of the bird guards we fit are made of high quality aluminium alloy (some are stainless steel) and are protected with powder coating. They also have a rain cap as standard.
