Office window and glass cleaning

Internal glass, glazed partitions and meeting room screens kept smear-free, with external office windows arranged where access allows. Typical UK costs.

In short: Office window and glass cleaning covers internal glazing, glass partitions, meeting room screens, glass doors and balustrades, with external windows cleaned separately by water-fed pole or other safe access methods where possible. It suits modern offices with lots of glass, where fingerprints and smears are very visible. Internal glass is usually done within regular cleaning hours, and external window cleaning for a small office building often starts from around £50 to £150 per visit.

Modern offices use a lot of glass: frameless meeting room partitions, glass doors, manifestation strips, balustrades and screens between desks. They let light through but show every fingerprint, smear and splash, and reception glazing is often the first thing a visitor notices. Internal glass is usually built into a regular contract as a weekly task, with glass doors and touch points done on every visit, using purified water or a suitable glass cleaner and microfibre to avoid streaks.

External windows are a separate job because access and safety are different. Ground and low-level windows can often be reached from the ground with a water-fed pole system, which uses purified water and avoids ladders. Higher floors may need a cherry picker, rope access or a building maintenance unit. The Work at Height Regulations 2005 require work at height to be avoided where possible and properly planned where it is not, so the method is chosen before a price is given.

How it works

Survey the glazing

Internal and external glass is counted and measured, and access for each elevation is checked.

Agree the method

Internal glass is added to the regular schedule, and a safe method is chosen for any external windows.

Clean and check

Glass is cleaned with purified water or suitable products and checked in daylight for streaks.

Set the frequency

Internal glass is usually weekly, and external windows are often monthly, quarterly or every eight weeks.

Office window and glass cleaning: FAQs

Can regular office cleaners clean the outside windows?

Usually only if the windows can be reached safely from the ground or from inside, such as tilt-and-turn windows. Higher external glazing needs specialist window cleaners with water-fed poles, powered access or rope access, along with suitable training and risk assessments. Cleaners should not be asked to lean out of windows or use ladders for this work.

What is a water-fed pole system?

It is a lightweight telescopic pole with a brush head that sprays purified water onto the glass. Because the water has had its minerals removed, it dries without spots, so no squeegee or chemicals are needed. It lets window cleaners reach upper storeys from the ground, which is safer than using ladders.

How often should office windows be cleaned?

Internal glass and glass doors in busy areas are usually cleaned weekly, with doors and push plates done on every visit. External windows are commonly cleaned every four to twelve weeks, depending on how exposed the building is to traffic dirt, sea air or nearby construction. Many offices choose quarterly external cleans with extra visits before key events.

Why do our glass partitions still look streaky after cleaning?

Streaks usually come from too much product, dirty cloths, hard tap water drying on the glass or cleaning in direct sunlight. Using clean microfibre cloths, minimal product or purified water, and finishing with a dry buff normally solves it. Fingerprint-heavy areas such as door edges may need attention on every visit.
