Chimney Cowl / Terminal Fitting


Some of the most common chimney problems can be prevented with correct fitting of an appropriate terminal or cowl.  

Ideal examples of this are birds nesting, rainfall causing moisture issues in the chimney system, changes of wind direction causing smoke-back issues - all very common issues with chimneys which are in most cases preventable by fitting an appropriate terminal or cowl to your chimney pot.  

It is something often overlooked, which can result it far greater costs of remedy.    We offer various types of cowl fitting, from stainless steel high-top cowls, to anti-downdraught cowls to help with smoke-back issues and rotating cowls to assist with draw issues.  

We do not recommend or supply wire balloon bird guards. Although wire balloons prevent birds from entering the chimney, they still allow rain to enter the chimney, which can lead to damp build up. Another set back with wire balloons is that over time the mesh gets extremely thin and from the ground it appears as though the flue is protected, but from the roof - the top of the balloons rust out creating a hole for Jackdaws to pass through and build nests, which you won’t be aware of until problems occur. The main issue with wire balloons, is that they are not fixed - they are pushed into the pot and therefore without taking great precaution whilst carrying out a chimney sweep, it makes it extremely easy for them to be pushed off in the process of sweeping the chimney.  If your chimney has a wire balloon bird guard on a chimney that is in use, we recommend changing this for a fixed chimney cowl.

For redundant flue systems, we recommend installing vented terracotta "pepper pots". If the customer insists on using a wire balloon, then we make sure to use wire or jubilee clips to fix them to the pot so that they can not be easily knocked off or lifted by determined jackdaws.

Jack came today instead of Deri, but was equally cheerful and efficient, and did a very good, thorough, clean job. Wholeheartedly recommend!
Osian Jones
Messaged to check if they covered my area to do a chimney repair. Unfortunately they didn't but Deri took the time to send a video explaining the steps he would take to try and resolve the problem. Didn't have to, but shows what a professional he is by doing it. Would highly recommend. Thanks again for the help
Carl Clement
Superb service, Deri is knowledgeable, helpful and a pleasure to have in our home. Chimney swept quickly and professionally, useful advice for a first time stove owner, and even performed some additional maintenance for us. Highly recommended.

Thank you Derri and Jack your workmanship is incredible and you have transformed my fireplace. You were both polite and made me feel reassured that I was in safe hands. Nothing was a bother and you left the place clean and tidy every evening when you left. I recommend this skilful pair even if it means waiting for them. Derri still in touch to support me with what fire surround to have if I decide to have one. Thank you both for helping me on my long journey to make my place look amazing
Owen Pollard-Rice
Deri made an excellent job of our installation and finished to a very high standard. His workmanship is not common these days as he takes the time to make sure everything is completed to a high standard and really takes care to look after your property. I would thoroughly recommend him for any installation.
Nick Reynolds
Jack did a superb job cleaning the wood burner and chimney. He was also happy to share his expert knowledge to assist me further. Excellent service and I’m delighted to be added to their calendar for a regular visit.
Capers C
Excellent service given. We are extremely pleased with our installation from Deri. The work was carried out quickly and to a high standard. I have no reservations with using his services again and would recommend anyone to get in touch with him for sweeping and installation.
Anne Parker
The chimney in our 'new' house was swept by Deri. He is very affable and a pleasure to converse with. We were kept informed about our appointment and he turned up when he said he would. The job he did was very thorough, and there was no mess at all - which we have had with other sweeps! He also replaced the rope door seals, and was very particular about the way it was done. He was happy to answer all my questions and gave us advice regarding some issues we had with our stove. We have yet to light it, but I am confident all will be fine when we do. Deri is now booked to sweep our chimney next year!
Les Rennie
We had Deri to clean our chimneys last year and we were really impressed with his work and so asked him to come back and sort the wood burner in our lounge out. This was quite a big job which involved removing the hearth and replacing the flu amongst other things. Deri and Jack worked so hard and we couldn’t be happier with the finished result. When they had finished the job they left the room in an immaculate condition. We had to wait a while for them to come due to them being so busy but they are definitely worth the wait and we will be using them again. We would thoroughly recommend this company we really can’t fault them.
Mark Berridge
These guys are great from start to finish! Lots of information. Regular contact. Arrived on time ( no Pembrokeshire Promise) and thoroughly professional. Also really tidy workers!! Totally recommend!
Steve Davies
What a pleasure to meet Deri and Jack great hard working and professional craftsmen who overcame unforeseen problems with ease and a smile they fitted a “hungry penguin “ and a slate hearth in my conservatory and came across issues with the routing of the flue. I was kept informed at every step. They were meticulous in their work and cleaned up to a very high standard I cannot recommend highly enough. (View Image Review on Google - https://g.co/kgs/tVGJ4dT)
