Chimney Smoke Draw & Pressure Testing


There are two types of smoke test in the industry, referred to quite simply as 'Smoke Test I' and 'Smoke Test II'.   The differences are quite simple as we detail below - but only one is offered as a stand-alone service, while the other is completed as part of a chimney sweep.  


Smoke Test I (‘pressure test’)

A smoke test type 1 is used to test the integrity of the flue. If a chimney stack had any integrity issues, whereby the smoke was able to leak out into the property, the smoke test type 1 would highlight these areas in order for them to be remedied. To carry out this test the flue is sealed off at the fireplace, access is gained to the top of the chimney to seal off at the top of the pot. With pressurised smoke within the flue system we inspect for any smoke evacuation points (leaks). Any leakage points will be highlighted and any additional work required provided with an estimate to return to rectify. 

The cost of the Smoke Test Type one is dependent on the height and access to the chimney stack.  We have based our listed pricing on a typical single or two story height property with a standard height chimney accessible with roof ladders.   Please bear in mind in some cases scaffolding would be required, which would of course be an added cost.  


Smoke Test II (‘smoke evacuation test’)

A smoke test type 2 is carried out as standard after a chimney sweep, on systems whereby we can not confirm with certainty that the brush has cleared the top of the flue, or where we want to test the draw of the flue. It is usually done by heating the flue at first and then lighting a smoke bomb to see how well the smoke evacuates. 

Our smoke evacuation test (smoke test type two) is included as part of all of our sweep packages when required.

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)
