Daily office cleaning keeps desks wiped, bins empty and washrooms stocked. But some dirt accumulates where daily cleaning doesn't reach — in carpet pile, on upholstered chairs, inside the fridge, on top of cabinets, in vents and behind the kitchen appliances. That's what an office deep clean addresses. The question is how often you need one.
The short answer
For most offices, every three to six months. Quarterly for busy, high-footfall or client-facing offices; twice a year for smaller or lower-occupancy spaces. On top of that, book a deep clean at specific trigger points (below).
What an office deep clean includes
- Carpets hot-water-extraction cleaned, including under desks where accessible
- Upholstered chairs and soft seating cleaned
- Hard floors machine-scrubbed and, where appropriate, re-sealed or buffed
- Kitchen: appliances pulled out and cleaned behind; fridge, microwave, dishwasher and cupboards inside and out; tiles and grout
- Washrooms: descaled, grout and sealant cleaned, vents and high-level areas dusted
- High-level dusting: tops of cabinets, partitions, light fittings, vents, blinds
- Desks cleared (by staff) and fully cleaned, including cable trays and monitor stands
- Internal glass, partitions and door furniture
- Touch-point sanitisation throughout
Trigger points for an extra deep clean
- Moving in or out of an office — both for handover and for a fresh start
- After refurbishment or building work (see after builders cleaning)
- Illness outbreaks — a sanitisation deep clean helps break the cycle
- Before an important visit, audit or investor meeting
- Changing cleaning contractor — start the new contract from a clean baseline
- Seasonal — many businesses schedule one in January and one in late summer
Factors that push frequency up
- Headcount and desk density
- Client or public footfall
- Kitchen use — an office that cooks needs more than one that reheats
- Carpet colour and traffic — light carpets in corridors show soiling fast
- Proximity to main roads or construction (dust ingress)
- Pets or hot-desking
Deep cleaning and your daily contract
The most cost-effective approach is to build periodic deep cleaning into your office cleaning contract, so it's scheduled and budgeted rather than booked in a panic. At Danitam we include a quarterly or six-monthly deep clean option in every office cleaning quote in Manchester, carried out by the same team who know your building — usually over a weekend or evening so nobody is disrupted.
