Window Cleaning


We have placed significant investment in window cleaning technology with our own drop mapping, fabric auditing and cradle checking systems that deliver live reports via tablets or other mobile devices.

Principle Window Cleaning started in 2014 and now directly employs more than 70 staff. The team are amongst the best and most highly trained in the industry and bring huge commitment and a wealth of experience to our window cleaning operations, which includes some of the most complex vertical cleaning in the Capital. We have our own abseilers and use a variety of equipment including reach and wash systems, ropes, MEWPS, cradles and BMUs.

Planning is meticulous. Window cleaners will use an app to check weather and wind speeds days in advance so they can plan tasks and schedule safely and effectively, and keep clients up to date. Anemometers are used to check wind speed and work will be postponed if winds are too high or if the temperature is forecast to be too cold. Our window cleaning team is IT literate and able to record and report in real-time using our cloud-based systems. Staff provide equipment checks and sign off on their mobile phones, taking pictures as they need to and sending to our portal.
