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.

AVOID! Mr Art 13 (father&son) ABANDONED our 7-room project. Started 2 beds and a wetroom that now needs redone. After 10 weeks and 50% of the quote PAID, no room was left usable. Gave constant excuses for delays: “prices doubled,” “faulty pipes,” etc. They told us they DON'T CUT CORNERS and explained how coving screws should be filled and sanded, yet they paint over screws, leaving drips on the walls, flooring laid on an uneven base they poured, tiling on a dirty dusty wall, using unfit materials, etc.
