How often should you clean your windows?

Most homes benefit from a professional window clean every four to eight weeks. Shops, offices and other businesses usually need cleaning more often, typically fortnightly or weekly, to keep a smart frontage. The right interval depends on where you live, what surrounds your property and the time of year, so treat four to eight weeks as a starting point rather than a fixed rule.

Recommended window cleaning frequency

Here is a realistic guide for different property types. Adjust based on how quickly your glass actually gets dirty.

Property typeSuggested frequency
Family home, average locationEvery 4 to 8 weeks
Home on a busy road or near treesEvery 4 weeks
Shopfront or retail unitWeekly to fortnightly
Office buildingFortnightly to monthly
Conservatory glass and roofTwice a year (see below)

What makes windows get dirty faster?

Two identical houses can need very different schedules. These factors speed up how quickly glass grimes over:

  • Busy roads: traffic film and dust settle on glass quickly.
  • Nearby trees: sap, pollen and bird mess all mark windows.
  • Weather and season: autumn and winter bring rain spots, mud and salt.
  • Coastal or rural exposure: salt air and farm dust both build up fast.

It is not just about the view

Regular window cleaning does more than keep your glass clear. Dirt, grit and organic matter sitting in frames and seals can shorten their life, and grime left on glass can etch over time. Cleaning the whole window, glass, frames and sills, protects the unit and keeps everything working as it should. Our window cleaning service always includes frames and sills, not just the glass.

What about conservatories and hard-to-reach glass?

Conservatory roofs and upper-floor windows collect dirt, moss and algae and are best cleaned with the right reach-and-wash equipment rather than ladders. Conservatories usually need attention once or twice a year; see our guide on cleaning a conservatory roof safely. For everything else, modern water-fed poles reach upper storeys safely from the ground.

We clean residential and commercial windows across the area, from Derby to Nottingham, on a schedule that suits you.

FAQs

Frequently asked questions

Most homes benefit from a clean every four to eight weeks. Homes on busy roads, near trees, or in exposed locations dirty faster and may need cleaning every four weeks to stay consistently clear.

Shopfronts and retail units usually need weekly or fortnightly cleaning to keep a smart frontage, while offices often work well on a fortnightly to monthly schedule. A clean frontage directly affects how customers see your business.

It should. A proper window clean covers the glass, frames and sills, because dirt left in frames and seals can shorten their life. Cleaning the whole unit protects the window, not just the view.
