Most schools have their main window clean in the summer holidays, when the site is empty and parking is free, with a lighter clean of entrances, halls and reception glass in the Easter or October half-term. Term-time visits are possible but need careful planning around pupils.
Why the holidays work best
A school site in the holidays is a different place: no pupils, no drop-off traffic and usually only the site manager and a few staff. That makes it the easiest time to set up hoses, reach every elevation and clean inside classrooms without disturbing anyone.
The summer holiday is the natural slot for the big clean, because it is long enough to fit around decorating, flooring and other contractors. Many site managers book it early, as July and August get busy for every trade.
What should be cleaned during term?
Entrances and reception glass take the most hand marks and are what parents and visitors see first. A short visit every half term or every term keeps them looking right. Sports halls and dining halls with large glazed walls may also suit a mid-year clean, especially if they are used for events or lettings.
Term-time visits are best timed for INSET days, after school or very early in the morning. Water-fed pole cleaning is quiet, and the cleaner stays on the ground, so it fits around a working school more easily than ladders or a cherry picker.
What about safeguarding and site rules?
Every school has its own visitor and contractor rules. Expect to sign in at reception, wear a visitor badge and follow the site manager’s instructions about where to park, which gates to use and which areas are off limits. If the clean happens during the school day, it should be planned so the cleaner is never working inside areas with pupils present.
Ask the cleaning company what checks and paperwork they can provide, and tell them early what your school or trust requires. It is much easier to sort before the first visit than on the morning of it.
How high can school windows be cleaned from the ground?
Most schools are one to three storeys, which is well within reach of a water-fed pole from the ground. Windows above flat roofs, canopies and covered walkways can also be reached without climbing, which is one of the main reasons schools moved away from ladders.
The things that limit reach are usually access, not height: fenced play areas, temporary classrooms close to the main building, planting beds and plant rooms. These are all checked on a site survey.
A simple yearly plan
Summer holidays: full clean, outside and inside. October half-term: entrances, reception and halls. Easter: outside of all ground-floor glass and entrances. That pattern suits most primary and secondary schools, and it can be scaled up or down for nurseries, academies and colleges.
Quick questions
Can you clean during the school day?
Yes, if planned with the site manager, though holidays and INSET days are easier.
Do you clean nurseries and pre-schools?
Yes. Smaller sites often suit a clean every half term.
Can trusts with several schools have one contract?
Yes, with a separate line and invoice for each school.
