Extensions- 18 Sep 2024
Chris was quick to respond to my enquiry and came round to view the premises and offer a quote straight away. Chris and his team took down and old conservatory and turned it into an extension. All the team were great, even my super shy son was chatting away to the chaps after school. All works completed in the time frame and to a great standard. I took advantage by asking for other jobs while the guys were here, and Chris was so helpful. I will definitely be keeping Chris in mind for any future works.

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.

I got a good feeling as soon as I met Darren from Keystone. Sometimes, I find builders and tradespeople difficult to talk to but Darren was super friendly and chatty, as we went through my plans. Darren's input was really helpful and he and his team got the work done quickly and efficiently; also couldn't believe how tidy they were, thought there was going to be mess everywhere! Amazing job, at a really good price and great communication throughout...can't recommend highly enough.
