A reliable construction expert
I am a contractor based in County Down and have been in the industry for over 30 years. I have worked in various areas of construction throughout my career ranging from ground-up housing construction, solar installations, property repair and refurbishment, to even set construction for Game Of Thrones.
I have worked with numerous material suppliers, manufacturers, and various tradesmen such as plumbers, electricians, and structural engineers. The relationships that I have built with these contacts not only allow me to plan every aspect of development that a client may need, but they also allow me to make fair and competitive quotes for all work that I do.
