Carpentry- 25 Mar 2022
Colin was professional and friendly at all times. He appreciated that we had a business to run while he worked and it worked perfectly. The quality of his work was exceptional and he kept cleaning as he went and ensured everything was working perfectly before he left. I would recommend him for any work you need and we will be using him again very soon on the projects. Thank you.

Bricklaying- 2 Oct 2022
Andrew came to look at the wall to advise me on the work required, he gave me a quote for two sections of the wall, the first part required replacing damaged bricks and part rebuilding, the second repointing. I accepted Andrew’s. quote and started the work the following Saturday. The completed work is far beyond what I thought would be possible.) Many thanks Shaun. Robert.
