Hard Flooring- 11 Sep 2025
I’m not happy with the job George did for me. Just a day the floor started moving. I contacted him and he cut the call on me like I’m a piece of shit. I am a sick single mum struggling. He took £2500 from me and the job is not good. I’m sad and disappointed in him.😭😭😭😭

Joinery & Cabinet Making- 28 Oct 2022
Rafal was very helpful, and came up with alternative solutions to the job too from what I'd first suggested. He was prompt, cleaned up each day, and did a really good job which I'm very happy with. It was slightly worrying not to get a confirmed price for the work beforehand, just an estimate, but it turned out that was because it was hard to tell the time the job would take, and in the end what he did charge produced a really good result. I'd highly recommend him.

Extensions- 14 Feb 2021
Adam and the DJ Russell team have been great, I cannot recommend them highly enough. The job started on the 3rd of November 2020 and was completed on the 3rd of February 2021. All the neighbourhood have been impressed with the speed and accuracy of workmanship displayed. From the general builders (Bruce, Martin and Steve) to the brickies (Paul, Matt and Steve) and to the carpenters (Paolo and Dominic) through to the electricians (Max and his team) and the plumbers (Mark and Jack) and last but not least the plasterers (Gary and Craig) they all have kept me occupied with producing huge quantities of tea and coffee (-: but most of all they have constructed a quality extension for our home. Thank you for all your hard work and professionalism.

Catalin completely transformed both bathrooms! He listened to our requests and has come with good solutions to our problems, including recessed shelves and replacing the hot water cylinder with a combi boiler, to give us more space in the bathroom. The work was done to a very high standard and has helped us to source materials and sanitary ware. Catalin and his team has done a fabulous job! I highly recommend him!
