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!

They both are very friendly and are very good at being neat and paying close attention to detail. Alex offered a reasonable price and made sure they both took their time so it was done to a very high standard and to my satisfaction.

Cannot recommend highly enough. The work was finished to a really high standard. They were really adaptable when the tiles we had ordered failed to arrive on time. They adjusted their plans and worked really hard to get the work done on time, without compromising on the quality of the finish. They were also really considerate of working around young children, and were very patient with little interruptions from a fascinated six year old!

Rob and his team did a really high quality job and we are very pleased with the end result (and I am the son of a builder, so my expectations were high to start with).. The finish is excellent on the render and the quality is constant through what was a fairly large rendering job on my detached house. The team were tidy and worked hard to the deadline throughout the process. If you need a high quality rendering job, then I would highly recommending considering Rob's services.

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.
