Owen and his team were a joy to employ. They had an upbeat can-do attitude to work that involved demolishing an internal wall and reconstruction and refurbishment of a chimney breast. They worked quickly and efficiently, and to a very high standard. They started early each day and worked with enthusiasm and drive, always leaving the site clean and tidy. I am absolutely delighted with the outcome!
