M Allan
When initially discussing the project, Tony explained any problems/issues clearly and then provided a detailed estimate for the works. He completed the work efficiently and notably kept a tight handle on chosen subcontractors! The professionalism and expertise shown by Tony and his team will come in handy again in the future, I'm sure.
