in Facilities Management

Pioneering with integrity

Lewis & Graves is one of the most respected Facilities Management Companies in the South East. We work mostly in the education and Local Authority sectors. As you can imagine, both these areas are notoriously difficult to keep clean, safe and hygienic. We have become very good at it, though.


In 2006 we successfully contained and eradicated serious viral outbreaks in four Kent schools.


All the directors and staff have a deep personal commitment to the success and reputation of the company. We are always looking at new materials, equipment and methods of working, not only to improve the standard of service delivery but also to increase our productivity levels wherever we can. This is why we came across STERI-7.


They have a great range of high-level, broad-spectrum biocidal disinfectants with really impressive up to 99.9999% kill rates. These and a their fogging machines make our business promises so much easier to deliver.


At Lewis & Graves we maintain that a continuous quality service can only be achieved and continued successfully by investing in quality materials and equipment like those offered by the STERI-7 team.


It’s a great partnership.

Wherever large numbers of people congregate, you’ll find a high risk of contamination. Offices, wash rooms, restaurants, cafés; the list is almost endless.


Trying to keep these spaces simply clean, never mind hygienic, is a never-ending battle. They are happy breeding grounds for a wide range of nasties; from the unpleasant to the downright hostile. Bacteria like E.Coli and Salmonella and viruses like Norovirus and Influenza are everywhere and on everything.

STERI-7's High Level Disinfectant Cleaners are gentle yet powerful enough to satisfy the most stringent criteria.


STERI-7 XTRA is a one stage High-Level Multi-surface Disinfectant Cleaner. One application of STERI-7 XTRA effectively kills bacteria, viruses, fungi, spores and moulds up to 99.9999% on a surface. Destroying many harmful bacteria and mycobacteria including MRSA, Salmonella, E.Coli. P. aeruginosa, Listeria and Tuberculosis (TB), spores such as Clostridium Difficile and Bacilis cereus, viruses from H1N1 (Human Flu) through to Norovirus and even fungi and yeasts like Aspergillus niger and Candida albicans.


Yet despite being poisonous to pathogens, STERI-7 products are non-irritant* and non-corrosive. All STERI-7 products also use our unique Reactive Barrier Technology.


Reactive Barrier Technology is a 7th Generation specialised Micro-Emulsion which provides an optional sustained release system – this means that the Reactive Barrier can be switched on or off depending on the situation. It’s simple, if you rinse STERI-7 XTRA after application you remove the Reactive Barrier, if you leave STERI-7 XTRA to dry you enable the Reactive Barrier Technology providing added biosecurity and PROTECTION BETWEEN CLEANS.


STERI-7 XTRA’s unique properties ensure a hygienically clean and safer environment. When used regularly STERI-7 XTRA will reduce the chances of cross contamination.


STERI-7 disinfectant and disinfectant cleaners can be used in our proprietary STERI-7 BioMist ULV Fogging Machine. STERI-7 BioMister's powerful 1250 watt motor produces 4,500 cubic feet of fog per minute and can reach a distance of 10 metres; disinfecting an average working space in less than quarter of an hour.


Anyone from a café to a restaurant chain, an office manager to the CEO of a facilities management company like Lewis & Graves can use STERI-7 products liberally, knowing that they will not only offer exceptional cleaning but also unparalleled and formidable support in their continual conflict with contamination and infection.
