Quality work

From the initial consultation to the completion The Kelray team were professional, polite, friendly and patient. They kept us up to speed with every step of the alterations. Advice was offered when needed. I was particularly impressed by the quality of the work. They were considerate to our neighbours making sure that the entrance, hallways etc to our apartment were always kept clean. We are delighted by the end result and would have no hesitation in recommending Kelray to anyone.
