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!

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.

Floyd was great from when he came to measure up and give us the quote to working through some difficulties and creating a finished kitchen. Nothing was too much effort and he went above and beyond with things he didn’t need to. Was so happy with the kitchen I have recommended him to friends as well.

Mariusz came to give us a quote for complete strip out and refit of small bathroom. We already had an idea of how the new bathroom should look and had chosen almost all the new fittings, etc. Mariusz suggested a completely new layout, which we would never have thought of and many different fittings. We decided to go with Mariusz's layout and many of his suggestions for the fittings. The finished bathroom is absolutely outstanding and beyond our expectations. Mariusz is truly a master craftsman.
