Craig got in touch quickly, gave me a rough estimate over the phone and answered all my questions. Surveyor arrived on time, gave instant quote. Price was good. Michael and (another) Craig turned up to do the job on the day, time given. Good, tidy job. Can't fault anything, from start to finish!! Would recommend!

George and his team are experienced builders, replaced my front door with a custom frame/sidelights and raising the floor level in the hallway quite quickly - in fact, they were the only who came next day, gave a quote straightaway and were ready to start in just couple of days. They also had all the necessary tools and materials, were ready to buy something additional quickly on the day - if further adjustments were required to fit everything as I asked. Thanks a lot for your help, guys!
Dmitry
Highly recommend. These guys did a fantastic job of constructing our pergola and decking. Very hardworking and reliable. The job was completed in the time frame agreed and to a very high standard. We would 100% use them again.

One to be careful with is the electrician Ben. The work seems alright, but his advise left us with excessive lighting in Kitchen and sitting room and our decision against TV sockets in ALL rooms was interpreted as NO TV and phone socket at all, which then later had to be added at extra cost and left the choice of suppliers limited. His crew also did the plumbing and the bathroom installation and the later was not done to the general standard of U&U constructions work.
