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.

I highly recommend Thomas and his team for their excellent workmanship. They were punctual, polite, and trustworthy, completing the job — detailed pointing, brickwork replacement, installing a new gutter and downpipe, repairing a wooden patio door, and tiling. All work done to a high standard with quality materials. He provided valuable advice, and the site was left clean. Working with him for the first time, I appreciated the professionalism and good rapport established. A great experience overall!
