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 at Quebuild went above and beyond for us on this job. He completed all the work in a timely manner and for a very reasonable price. He was super knowledgeable and extremely attentive to detail, making sure to leave a high quality finish in terms of decoration - and he came back afterwards to address a few small things that needed doing. He was also a pleasure to have around - and I would highly recommend him for any other work. 10/10.

The work completely was of a very high standard with immaculate attention to details. Jerry was punctual from the survey stage to the end of the work. He sorted little snags with the wall, separated the work area with a plastic sheet so the dust was minimised. After each day, my home was left clean and the job was progressing well.
