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.

Ian came round to take a look at a damp patch that had started showing up on one of the utility room walls. He turned up on time, was really friendly, and clearly knew what he was talking about. He gave everything a proper check over and explained what was likely going on in a way that actually made sense. He didn’t try to make a mountain out of a molehill or push for any unnecessary work—just gave honest, practical advice on what to do next. Really appreciated how straightforward and helpful he was.

I have been an electrician since 2008, I do have my 18th edition electrical installation certificate, and I can sign off electrical work. I am a very creative electrician with many great ideas on what will look good and what will look Great.
Dev was very personable and did a fantastic job. He left the place cleaner than when he started and managed to correct a number if short cuts taken with the previous hood installation. I would definitely recommend if you are looking for an electrician

John and the team did an outstanding job. It was easy to work with John and he was very knowledgeable, and provided very sensible advice.
