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.

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.

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.

They were highly professional, communicative, organised & very skilled in their undertaking of my job. I was extremely nervous & anxious about making a choice for this work with my knowledge of the trade being zero. I definitely made the right choice!

I was apprehensive at first as I spoke to so many electricians and got so much info mixed up. Felix is very experienced and explained with clarity, which put my mind at ease. The job was honestly priced and within my budget. He is friendly and conscientious. Tidied after himself. I will definitely recommend.

Very strong recommendation for Adam. My shower temperature has not been great for a while. A previous plumber scared me by implying it was a major job - replacing, retiling, expensive, destructive - so I put it off. Charlie, however, managed to sort it by just correctly fitting the cartridge. No fuss, minimal cost. Brilliant.
