NII Clean commenced trading in 2019 when Mark and Erica Donley began to see an opening for a company who could professionally clean the outside envelope of commercial and residential buildings.

Our services and skills have developed quickly as we have helped many customers restore and renew the appearance of their property.

In June 2021 NII Clean acquired a high profile workshop and trade counter on the Bushmills Road in Coleraine. These premises serve as both a base for NII Cleans's services and a new show room servicing both private and trade customers where we sell, Service & Repairs. Main stockist for PdPro, Streamline Systems & CBD Pressure Washers
