Extreme Cleaning and Facilities, often just called Extreme or Extreme Cleaning, is a cleaning and facilities company based at Regal Court Business Centre on Slough High Street. We bring three services together under one brand, so a business, landlord or property manager can use one team for the whole building instead of juggling several suppliers.
What Extreme Cleaning does
Cleaning. Office and commercial cleaning, deep cleans, end of tenancy, window cleaning, carpet cleaning, communal areas, after builders cleaning, and cleaning for schools, healthcare, retail and industrial sites.
Extreme cleaning. The jobs most cleaners turn down: hoarded homes, house clearances, fire and flood damage, biohazard, crime scene and trauma cleaning, needle sweeps, graffiti removal and void properties. Available 24/7.
Facility management. Planned maintenance, reactive repairs, compliance checks, grounds maintenance and waste, all on one contract.
Where we work
We are based in Slough and work across Berkshire, Buckinghamshire, London and the South East, and further afield for larger contracts. See the areas we cover, or our pages for Slough, Reading, Maidenhead, Windsor, High Wycombe and Bracknell.
