Cannot recommend highly enough. The work was finished to a really high standard. They were really adaptable when the tiles we had ordered failed to arrive on time. They adjusted their plans and worked really hard to get the work done on time, without compromising on the quality of the finish. They were also really considerate of working around young children, and were very patient with little interruptions from a fascinated six year old!
