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.
