Extreme Cleaning & Facilities provides cleaning services, extreme cleaning and facility management from our base in Slough. Offices, schools, surgeries, shops, warehouses, landlords and households all use the same accountable team.
Most of our cleaning services are regular contracts: offices cleaned before staff arrive, schools in term time and the holidays, surgeries around clinic hours, shops before they open and warehouses around their shifts. Every contract starts with a checklist agreed with you, a written price and one point of contact, so you always know what is cleaned, when and by whom.
Our one-off cleaning services include deep cleans, end of tenancy cleaning, after builders cleaning, carpet cleaning and window cleaning. They are booked around your dates, priced in writing and often lead to a regular contract once customers have seen the standard.
When a job goes beyond normal cleaning, our extreme cleaning team handles hoarded homes, house clearances, fire and flood damage, biohazards, crime scenes, needles, graffiti and void properties. The team works in protective equipment, quietly and without judgement, and is available 24/7 on 01753 935935.
For whole buildings, facility management brings planned maintenance, reactive repairs, compliance checks, grounds and waste under the same contract as your cleaning services, so one team looks after the inside and the outside of the building.
We are based on Slough High Street and our cleaning services cover London, Berkshire, Buckinghamshire, Surrey, Hertfordshire and the South East, with larger contracts up to 200 miles away. See our pages for Slough, London, Reading, Windsor and the full list of areas we cover.
Every job is priced on its own, based on the size of the site, how often you need us and its condition. We never publish one price for everyone, because no two buildings are the same. Our price guides explain what affects the cost of office cleaning, end of tenancy cleaning and deep cleaning. New customers get 20% off their first job, taken off the written quote.
Use the quote form on this page, call 01753 935935 or send photos on WhatsApp to +44 7470 913065. We call back within working hours, Monday to Friday 9am to 5pm, and emergencies are answered at any time. Whether you need regular cleaning services for one office or one supplier for a whole portfolio of buildings, the first step is the same short conversation.
One team, one point of contact and one written price for all your cleaning services, with 20% off the first job.
