Bujar was very prompt in response to my initial posting, calling to assess the job within a day and then confirming a start date for the work. He and his team did an excellent job on the hall tiling and also managing the cloakroom plumbing ( moving a sink and toilet) to complete the tiling here. I would highly recommend him and his team for doing a great job.
