Colonial's cleaning focuses on every detail in order to deliver a quality image as well as extend the life of your parking assets. Supplementing our man-power and elbow grease with technology, we utilize the most current riding sweepers and scrubbers for parking facility cleaning. Regular sweeping keeps dust and debris from accumulating on deck surfaces. Semi-annual scrubbing, which includes scrubbing the deck with a wet soapy solution, removes corrosive salts and other contaminates from the surface of concrete parking structures minimizing structural repairs and greatly extending their life.
