What we Offer - Servicing / Maintenance Products & Pricing

As an essential service, we offer standalone products and services including subscription packages, to all of our customers. We are here to take the hassle out of organising your chimney sweep, to make sure your chimney is kept safe by being maintained at regular intervals, from the first service we carry out and going forward. With the biggest uptake of new clients being from Oct onwards, if you are having your first service carried out during winter, we encourage the next sweep to be carried out at the end of the burning season. This is a preferable time not just out of convenience, but by way of the fact that it is best to have the bulk of the soot from the burning season removed at the end of the burning season. This leaves the appliance ready to use, in plenty of time before winter sets in. 

Making your booking

Please note - If you believe there is a nest in the chimney or there is the likelihood of requiring additional services, please review all of the services we offer and make your booking accordingly.   If only booked in for a sweep we would not have allocated sufficient time to your booking to remove a nest for example, but would still have to charge for the call-out.  So it is important to ensure that bookings are made accordingly to the required service(s). 

First Sweep - What to Expect

With our booking system, you will be allotted an AM or PM timeslot. With the nature of our job, it isn’t always possible to determine how long each job will take, so we can not guarantee an exact timeslot at all times. We will of course be as accommodating as we can, endeavouring to cause as little disturbance to your day as possible. We are at all times conscientious of others’ property and take care to take adequate measures to maintain cleanliness. Our aim is to leave the property cleaner than it was when we arrived, by the time we’re all finished - so you needn’t worry about any mess. Dust sheets will be laid (with floor runners when appropriate) and the fireplace / stove is sealed up, keeping all the mess contained. 

Our preferred method is rotary power sweeping. A sweeping brush or flail head is used to clean the chimney. The soot/debris are then hoovered up using professional equipment and taken away. Depending on the type of soot, it is more often than not disposed of by way of licensed waste disposal or otherwise sparsely distributed in areas where it can benefit wildlife growth. 

Our sweeps will happily answer any questions or queries you may have at the time. If you are using our services for the first time and you are unsure of how safely your stove has been installed, we recommend booking a sweep & safety inspection.

Fab service. Thanks. Jack was friendly, methodical and did a great job.
Jac Hall
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.
F Rees
Deri came to my home today and worked above and beyond, I highly recommend him he has heaps of knowledge and runs a very professional business. Thank you very much!! I will without a doubt use him in future.
Peter Howell
Your expert advice, the installation with a chimney check and a new cowl were of the highest standard, with an organised work plan in a quiet engaging working atmosphere. Guaranteed to be the perfect combination at the ‘HEART of the HOME’. DIOLCH YN FAWR IAWN. Gwynne, Mary, Peter
Julie Griffiths
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 -
