Deciding how often to clean office windows is less about a fixed rule and more about matching the schedule to the building's exposure: how tall it is, how close it sits to a busy road, how sheltered or exposed it is, and how much the appearance matters to visiting clients.
This guide sets out a practical way to work out the right frequency for your building, what access planning involves for multi-storey offices, and what a regular contract typically costs.
Working Out the Right Frequency
As a general starting point, ground and first-floor office windows in a typical location do well with a four to six weekly clean, while upper floors on taller buildings can often go a little longer between visits since they collect less traffic grime, though they catch more airborne dust and rain streaking.
Buildings near busy roads, in city centres, or close to construction sites need more frequent attention, sometimes fortnightly, while sheltered suburban office parks can often stretch to six or eight weeks without visibly suffering. It is worth reviewing the schedule after any nearby construction work starts or finishes, since dust levels can change noticeably and a frequency that worked fine before may no longer be enough.
Access Planning for Multi-Storey Offices
Water-fed pole systems using purified water now cover most buildings up to around four or five storeys from ground level, reaching upper windows without ladders or cherry pickers, which keeps costs down and avoids disruption to staff and visitors. Taller buildings typically rely on a MEWP, rope access, or in some cases a permanently installed building maintenance unit if one already exists.
Whatever the method, scheduling around office hours matters. Most contractors are happy to work early morning, during lunch, or after hours to avoid disrupting meetings and client visits, particularly for ground-floor glazing near reception areas.
Interior Glazing and Reception Areas
Exterior cleaning keeps the building looking presentable from outside, but interior glazing, particularly reception areas, meeting rooms and glass partitions, often needs its own separate schedule since it is handled differently and usually sits within the general office cleaning contract rather than the exterior window round.
It is worth confirming with any contractor exactly what is and is not included, since exterior-only contracts are common and interior glazing left unaddressed can undercut an otherwise smart-looking building. Some office managers get around this by booking a specialist glazing clean quarterly alongside the general office cleaning contract, which covers meeting room glass and partition walls that daily cleaning staff do not always have time to reach properly.
Typical Costs
Regular exterior office window cleaning typically runs from around £30 to £100+ per visit for a small to medium office depending on size and access method, with larger multi-storey buildings priced individually based on square metreage and access complexity.
A fixed contract on a rolling schedule is usually cheaper per visit than one-off bookings, and it removes the need to remember to arrange cleaning ahead of client visits or inspections.
