Latest review:
I engaged Edi to work on a full renovation and refurbishment of a 4 bedroom detached house with front and back gardens on Blackheath’s Cator Estate. Edi did an extensive amount of work, including stripping out; plumbing; plastering; windows installation; carpentry; and decoration. In addition, after commencing the property work, once the scaffold had been erected, following sensible advice, Edi and his team replaced the roof and fully insulated the attic; fitted additional electric points; rebuilt the garden patio; and replaced the flooring throughout, in addition to other important jobs including re rendering and pointing of chimneys, building new wardrobes in the main bedrooms; and upgrading the radiators. A new kitchen, and two new bathrooms have been fitted. The kitchen redesign meant knocking through a wall with the lounge to create a larger space. Edi is a highly skilled craftsman, who thinks creatively as he works to make best use of the space, including shelf fittings, and additional lighting for example. He has built some beautiful wardrobes, and the internal decorations have brightened up what was previously a rather shabby looking house. In addition to the above, I wish to commend Edi for his professionalism, courtesy, and passion for doing the best work possible. On all the site visits I attended, and every time I spoke with him on the phone, it was striking how much he cared about the work that he was doing, his desire to ensure that the house would look the best. I always left site visits with the feeling that he cared so much about the house that he could be safely relied on to give the best advice to enable us to make the right decisions. I also noticed that Edi and his team would take the upmost care to keep the property safe, tidy and in good shape throughout the project. He can be fully trusted to look after any site he works on. He is intelligent and careful when it comes to safety and security. It has been a pleasure for Edi and his team to work with us over a period of around 6 months, and he did so much to reduce the stress of a significant project so that we could always rely on him to work methodically, patiently and sensibly, and to make best use of the resources available. His pleasantness shines through, and everyone I know who has spoken to him has always provided me with the most positive feedback I have no hesitation in recommending Edi to anyone who wishes to engage him for future projects, and is most deserving of the good words that I and others that work with him have to say about him.

Conversions - General- 27 Oct 2025
Bagnall Brickwork provided great service when I requested a quote to reinforce a wall for a heavy 50kg TV mount. Although they didn’t end up doing the work, their honest advice helped me realise that reinforcement wasn’t actually necessary for my situation. Thanks to their guidance, I was able to find a much more cost-effective and appropriate solution without compromising safety or quality. This experience shows their ethical approach - they prioritise giving trustworthy advice over making unnecessary sales. Highly recommended for anyone seeking professional, reliable, and principled brickwork or building services.

Architecture- 20 Nov 2016
This is the first time we are carrying out an extension work at our property. Sean worked with us from a very early stage, prepared the drawings, coordinated with the council and ensured that we received the building approval on time. He was always available to advice us (when requested) on design challenges, choosing installers and material choices which we found very helpful. We are very happy with his work and thoroughly recommend him.
