Manchester's weather is not kind to glass. Rain carries dust and pollution onto windows, dries, and leaves a film that dulls the view and the look of your property. So how often should windows be cleaned? It depends on the property type, its location and what you're trying to achieve — here's our guidance from cleaning windows across Greater Manchester.
Homes: every 4 to 8 weeks
For most houses and flats, a 4-weekly or 8-weekly window clean keeps glass consistently clear. Four-weekly suits homes on main roads, near trees, under flight paths or with light-coloured frames that show dirt; eight-weekly suits quieter suburban streets. Most of our residential window cleaning rounds in Manchester are on one of these two cycles, with frames and sills included every visit.
Shopfronts: weekly to fortnightly
Retail glass works hard: fingerprints, rain splash from the pavement, traffic film and, in the city centre, the after-effects of a Saturday night. A shopfront on a busy high street usually needs weekly cleaning; a quieter parade can manage fortnightly. Restaurants and bars often add a weekly clean of doors and low glass even if the upper glazing is done less often.
Offices: monthly to quarterly
Office glazing is less exposed to hand contact but still picks up traffic film and rain marks. Monthly for ground-floor and reception glass, quarterly for upper floors, is a typical commercial specification. Internal glass and partitions are usually handled by your office cleaning contract.
Factors that mean more frequent cleaning
- Main roads and traffic: diesel particulates leave a grey film quickly
- Trees: sap, pollen and bird droppings
- Flight paths: south Manchester near the airport sees more airborne residue
- New builds and construction nearby: fine dust for months
- Coastal or exposed sites: wind-driven grime
- Light or white frames: show dirt sooner than dark frames
- Solar panels: clean twice a year to maintain output
Why regular rounds cost less than one-offs
Glass that's cleaned regularly never gets to the point of needing heavy work, so each visit is quick — and the price reflects that. A one-off clean of neglected windows takes longer, may need extra passes to remove baked-on residue, and is priced accordingly. Regular customers on our rounds pay from £15 per visit for a typical semi; a one-off first clean of the same house may be £25–£30.
Does the method matter?
Yes. Pure-water reach-and-wash cleaning leaves no detergent residue on the glass, so dirt has less to cling to and windows stay cleaner for longer between visits — one reason we use it. Read our comparison of pure-water vs traditional window cleaning.
