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.

John and the team did an outstanding job. It was easy to work with John and he was very knowledgeable, and provided very sensible advice. Other people quoted work which was over-the-top or wouldn't have solved the problem but John got right to the issue in a no-nonsense way. Quality of the work undertaken was very good, considering the age of the building and complexity. Would recommend.

James and Andy provided excellent advice and did a great job. The job revealed some extra work was needed but the changes were all discussed and agreed without pressure before being implemented and James was able to bring in extra team members whilst on site so the work was completed in a timely fashion. All of the team were personable and a pleasure to have on site.

Bit of difficulty getting messages answered, but arrived early on the agreed date, which was fine. Completed the task quickly and effectively. The company's terms request payment once the quote is accepted. I pay once the job is completed (unless it's a large job, requiring a deposit, for example.) He asked for cash and I said I preferred bank transfer. He started showing me messages on his phone from people who had paid cash in advance. I said I am not them and I would transfer the money this afternoon.
