Simon Gasson established this unique and versatile cleaning company in 1994 initially working hands-on alongside his cleaning operatives. Today he draws on his years of experience in the industry to sustain high company standards and support the training and development of his staff. Simon oversees operations and is responsible for client liaison across the company portfolio.
Simon introduced his brother Nicholas to the company in 1996; after gaining experience and product knowledge as an operative and supervisor, he became a partner in the business. Alongside his operational responsibilities, Nick controls finance and purchasing for the company. A county athlete himself, he also looks after our sports sponsorship activities with Blackheath & Bromley Harriers.
The partnership has gone from strength to strength with leading names in commerce and industry forming a solid client base, benefiting from the company’s highly skilled personnel, using the latest equipment and techniques, backed up by a strong operations team and help desk facility.
