Term time cleaning keeps a school ticking over. Staff and pupils get a clean building each morning, washrooms are maintained, and floors are vacuumed. What it cannot do is deal with the built up grime, staining, and residue that accumulates in the areas a daily routine does not reach properly.
That is what a school deep clean is for.
When Should a School Deep Clean Happen
The most common times to deep clean a school are during half term breaks, the Christmas and Easter holidays, and the summer shutdown. These windows give enough time to work through the building properly without any disruption to staff or pupils.
Many schools schedule at least one full deep clean per year during the summer, with lighter deep cleans at half term targeting the areas that need the most attention, such as kitchens, washrooms, and high traffic corridors.
What a School Deep Clean Actually Covers
A deep clean goes significantly further than a daily routine. Here is what a thorough programme typically includes.
Classrooms get a full clean from ceiling to floor. That means high level dusting of light fittings and ventilation, cleaning of walls and skirting boards, full floor treatment including stripping and resealing hard floors or deep extraction on carpeted areas, and detailed cleaning of desks, chairs, and storage that the daily clean does not have time to cover properly.
Kitchens and canteens require specialist attention. Grease builds up in extraction systems, behind equipment, and under surfaces over a term. These areas need degreasing, deep cleaning of all appliances, and thorough treatment of floors that standard mopping simply cannot replicate.
Washrooms are among the highest priority areas in any school. A deep clean addresses limescale, grout staining, tile cleaning, and full disinfection of all surfaces, including areas that are regularly cleaned but never fully sanitised during a daily visit.
Corridors and communal spaces accumulate dirt, scuffs, and general wear throughout a term. A deep clean strips floors back, removes built up marks, and restores surfaces to the standard they should be at.
Before and After
One of the most useful aspects of a school deep clean is the visible difference it makes. At Overstone School we carry out the ongoing daily cleaning contract with a team of four, two full deep cleans a year, and periodic carpet cleaning. You can see the full details in our Overstone School deep clean case study.
Getting the Right Team In
Not every cleaning company has the experience to deep clean a school properly. All staff working in educational settings must hold a current enhanced DBS check, and the products used must be appropriate for an environment where children will be present.
