How Often Should You Get Your Windows Cleaned? (UK Guide)
Four-weekly, eight-weekly, or twice a year? The honest answer depends on where you live and what your windows are made of. Here's how to decide.
For most UK homes, every 4 to 8 weeks keeps windows genuinely clean. Four-weekly suits busy roads, coastal towns, and homes with young children or pets. Eight-weekly is plenty for a sheltered rural house. Anything longer than twelve weeks and each clean becomes a restoration job rather than maintenance — which usually costs more overall.
What actually dirties glass
- Traffic film — the biggest factor on main roads and school runs.
- Salt spray — coastal homes need a shorter cycle, often 4-weekly year round.
- Pollen and sap — spring peaks, especially under trees.
- Rain shadow and mineral deposits — hard-water areas leave spotting faster.
- Building work nearby — dust bonds to glass and needs prompt removal.
A simple schedule by situation
- Main road, city terrace, or coastal: every 4 weeks.
- Suburban semi or detached, quiet street: every 6 to 8 weeks.
- Rural, sheltered, few trees: every 8 to 12 weeks.
- Conservatory roof: 2 to 3 times a year, separate from the glass round.
- Interiors: 2 to 4 times a year for most households.
One-off cleans typically cost 40–60% more than the same property on a regular round, because the job takes longer and the visit isn't part of a planned route.
What happens if you leave it too long
Dirt is mildly abrasive and holds moisture against seals and frames. Left for a year, organic growth builds in the corners, uPVC greys, and mineral spotting can etch older glass permanently. None of that is dramatic in a single winter, but over a decade it shortens the life of the windows you paid thousands for.
Getting an honest price for your frequency
Ask any cleaner to quote you on the frequency you actually want, not their standard one — a good operator will price 4-weekly, 8-weekly, and one-off separately so you can see the difference. Many UK cleaners now put an instant quote tool on their website so you can compare those figures for your own address in under a minute, without waiting on a callback.
