Most offices suit outside window cleaning every four to eight weeks, with entrance doors and reception glass more often. Quiet business parks can stretch to quarterly. Offices on busy roads, near building sites or under trees usually need the shorter end of that range.
What decides the right frequency?
Four things decide it: what is around the building, how much glass faces the public, who visits you and what the glass is like. Traffic, trees, building work and coastal air all shorten the gap between cleans. A glazed reception that clients walk through needs more care than a back elevation over a car park.
Start with the entrance. Doors, side panels and reception glass get hand marks every day, and they are the first thing a visitor sees. Many offices have the entrance cleaned every two to four weeks and the rest of the building on a longer cycle. That keeps the cost down without the front of the building ever looking tired.
Then look at the main elevations. Glass facing a busy road picks up a grey traffic film within a few weeks. Glass facing a field, a river or a quiet car park can go much longer. It is normal for one building to have two or three different frequencies on one contract.
Is monthly window cleaning too often for an office?
Monthly is not too often for a client-facing office on a main road, a showroom or a building with a large glazed atrium. For a back-office unit on a quiet estate, monthly is usually more than it needs, and every eight or twelve weeks is fine.
A simple test helps. Stand outside on a bright morning a month after a clean. If the glass looks dull from the car park or you can see streaks in low sun, monthly is right. If it still looks clean, try a longer cycle and check again.
What about the inside of office windows?
Inside glass gets dirty much more slowly than outside glass, but it collects dust, fingerprints and condensation marks, especially in kitchens, meeting rooms and anywhere people lean on the glass. Most offices have inside glass done every second or third outside visit, or twice a year.
Inside work needs a little more planning: desks near windows, blinds, plants and IT kit on sills. We agree a time, usually early or late in the day, and work room by room so nobody is disturbed for long.
Does the season change how often offices need cleaning?
Yes, a little. Spring brings pollen and tree sap, and autumn brings leaf debris and more road spray. Winter sun sits low and shows every streak on south-facing glass. Some offices add one extra clean in spring or autumn rather than shortening the whole year.
Pure water cleaning works in light rain, so a wet week does not have to mean a missed visit. Heavy frost and high winds are the main reasons a clean moves, and the visit is rebooked as soon as conditions allow.
How do you keep it on track?
Put the frequency in writing, with the elevations, doors and inside glass listed separately. Ask for the same day each cycle where possible, and an invoice after each visit that says what was cleaned. That makes it easy for a facilities manager or office manager to check the service at a glance, and to change one part of the schedule without starting again.
Quick questions
Can different parts of the building be cleaned at different frequencies?
Yes. Entrances monthly and the rest every eight or twelve weeks is a very common setup.
Do we need to be in the office when you clean?
Not for outside glass. For inside glass we agree a time with you.
Can you clean outside office hours?
Yes. Early mornings are common, and weekend visits can be arranged for inside work.
