We performed a comprehensive exterior clean on this commercial property in Watford to address significant organic growth and environmental staining. The project involved a deep clean of the horizontal corrugated metal cladding and the lower red brick foundation. Our team focused on removing dark vertical streaks and biological buildup that had accumulated across the building’s facade over time. We utilized specialized cleaning methods to restore the white and grey metal panels, ensuring the removal of all surface contaminants without compromising the fasteners or trim. The process successfully cleared the staining from the siding and service doors, revealing the original finish of the building materials.
