How often should Christchurch windows be cleaned?

Ask three window cleaners how often glass needs cleaning and you will get four answers. The honest version is that it depends on the house — but there is a sensible default for Christchurch, and a short list of reasons to clean more or less often. This guide walks through both.

The default: twice a year

For most Christchurch homes, a clean in spring and another in autumn keeps glass genuinely bright year-round. Spring clears the winter film — condensation residue, heater haze and the dust that settled while windows stayed shut for months. Autumn clears pollen, nor'wester dust and the insect debris of summer before the short days arrive, when every scrap of daylight matters most.

Twice-yearly also matches how dirt bonds to glass. Fresh grime comes off easily; grime left for eighteen months starts to need real persuasion. Regular cleans stay quick and straightforward, which is exactly what you want — glass that has slipped too far may need a deep clean for tired windows to reset it first.

Reasons to clean more often

• Busy roads: traffic film builds fast on street-facing panes. Homes on main routes often want those front windows done three or four times a year.
• Big trees: overhanging branches drop pollen, sap, honeydew and bird lime. Glass under trees can look tired within weeks in spring.
• Sea air: salt drift reaches further inland than many expect, and it hazes glass steadily. Eastern suburbs feel this most.
• Young families: ranch-sliders at toddler height collect handprints at an astonishing rate. A mid-cycle wipe of the sliders keeps things sane.
• Rentals and sales: inspections, re-tenancies and open homes all reward glass that sparkles on the day.

Reasons you can stretch it out

Sheltered, high, rarely-touched panes — the clerestory window in the stairwell, the glass nobody opens — stay clean far longer than working glass. There is no virtue in cleaning glass that is already clean; spend the effort where daylight actually enters your living spaces.

Workplaces run on a different clock

Shopfronts and entrance doors earn a monthly or fortnightly rhythm because customers see them every day — our business and office cleaning page covers that world. Interior office partitions can usually follow the twice-yearly home rhythm unless the lighting shows every mark.

Working out your rhythm

Start with spring and autumn, then notice which panes go first. The ones facing the road, the garden or the sea will tell you plainly whether your house is a twice-a-year house or a three-times one. And if you cannot remember the last clean at all, begin with the revival and build the routine from there.
