About us

Xenon began life in 1987 as Shiners Window Cleaners, which is now our specialist window cleaning division. Our aim – to provide 100 per cent customer satisfaction – is as focused now as it was back then.

At Xenon we have a number of core values which underpin the way we operate. We place great importance on internal communication and close liaison between staff and clients so that potential or real situations don’t become major issues. We believe that an enjoyable workplace brings benefits such as better cleaning standards and a higher level of staff continuity.
