Carpentry- 21 Nov 2016
George designed, built, installed a set of custom-made doors for under my stairwell. Lovely guy, very courteous and pleasant to have around, and the work was precise and pleasing. I had one or two tweaks I needed done to the doors after the job had been completed which he helpfully came back and did for me. Happy to recommend him.

Extensions- 13 Nov 2019
Mark managed the whole job (which was complex and involved three different rooms; change of use and new build) effectively and efficiently and engaged family members and friends in various trades as needed. With extensive experience Mark was able to make suggestions and put forward many ideas to improve the basic plans that we had which was most helpful. This included raising a ceiling level to a better height than we had envisaged possible and removing the need for a pier so that a wall could be flat throughout the new kitchen. Mark has a good eye for the aesthetics of a job. He is also very amenable to adding on extra smaller jobs in the process and even procuring some materials that I wanted in order to do something myself ! The workmanship and finish is high quality for a competitive price. I would not hesitate to recommend Mark and have, in fact, already done so for another couple of potential jobs. Finally, Mark is a really nice guy and great to have a chat and cup of tea with (two sugars!)
