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.

David McGill from Dm Brickwork and his team built a Garage on the side of my house for me they have done a fantastic job exceeded my expectations. The guys are really nice friendly and professional. They helped my disabled wife move her car in and out of the drive as she couldn’t and even helped her in with the shopping. I will be asking them to come back to build a patio in the future and recommend them to anyone that needs building work done.
