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!
