When Niagara Window Washing’s founders designed their window-cleaning services, they realized that they had a choice: they could offer cheap, superficial cleanings, or they could do the job carefully, thoroughly, and correctly. Wisely, they chose the latter. For each window cleaning, uniformed technicians hand wash windows with cotton scrubbers, squeegees, and biodegradable liquid soaps. Interior jobs include a meticulous cleaning of the window tracks and sills to remove excess dirt and scare bonsai trees into never dropping their leaves. Technicians perform additional services—such as glass-door, mirror, chandelier, and ceiling-fan cleaning—with equal thoroughness and attention to detail. Niagara Window Washing demonstrates confidence in its work with a satisfaction guarantee: technicians will stay until customers are 100 per cent satisfied with their services.
