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.

Andrey knows what he’s doing. The quality of his roofing work was excellent. He is busy but did complete the works when he said he would. Inevitably there were material supply delays but Andrey returned calls and kept me and my tenants informed throughout.

All keen to quote within hours of posting the job. Exchanged messages and wanted to book him for a quote. Sent the videos of the pipe as requested and then got deafed. Messaged to ask if it was something he could do or not. He apologised and said he'd review the video and come back to me...that was 24th March...now on 10th April and still not replied. Total time waster

Spencer at Pocock Developments project managed our work very well. From the fully detailed quote, to advising on any pricing changes and providing some extra plastering work - got to say everything was managed smoothly and transparently, and the one hiccup over the roof tiles was put right quickly. Plus we appreciated Myron and Ivan's eye for detail and managing their work around the weather. Our two dormers look great, so thanks Pocock Development and we'd definitely use them again ????
