Groundwork & Foundations- 5 Aug 2024
Des and Steve did an outstanding job digging for the foundation and pouring the concrete. They were professional, very tidy, and friendly throughout the process. I also want to express my appreciation for their plumber, Tony, who did a great job redoing the connection to the old cast iron water supply pipe and moving the stopcock. Their combined efforts were impressive and much appreciated. Now waiting for them to carry on with thd brick work.

Costal has done a great job. I wouldn't say he was the cheapest quote but after reading the reviews we hired him because of his reliability. I found him reliable and always turned up when we needed during the project. He recommended us other contractors and supported us to achieve the goal we were trying to achieve. I would recommend Costel 100% if you want to have reliable builders for your home. Thank you

Extensions- 6 Mar 2023
So glad we found Paul to conduct our house extension. Whilst work is still ongoing I have found Paul to be polite, considerate, and very experienced in the building trade, a big plus point is his costs and reliability. His knowledge is invaluable and has given us lots of ideas to consider during the build. Currently the team of builders conducting works to date have been lovely to be around and brickwork is amazing! Although still some way to go, looking forward to the next few months and the finished job.

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.
