How often should windows be cleaned?

A practical guide for homes, schools, offices and shops in Leicestershire.

By Pure Flex Cleaning LtdUpdated September 2026

Short answer: most homes are cleaned every 4–8 weeks, offices and schools monthly or quarterly, and busy shop fronts weekly or fortnightly. The right frequency depends on your location, how visible the glass is and what the building is used for.

Homes

For most houses in Leicestershire, a clean every 4 weeks keeps windows consistently clear, while every 8 weeks suits homes away from main roads and trees. Homes near busy roads, farmland or building sites get dirty faster and benefit from the shorter cycle.
