How Often Should Windows Be Cleaned in Guelph?

The standard recommendation for residential windows in Guelph is twice per year — typically once in spring (April–May) and once in fall (September–October). Here's why that schedule works and when to clean more often.

Why Spring Cleaning Makes Sense

Spring window cleaning in Guelph addresses:

• Winter film buildup: Road salt spray, calcium deposits from ice melters, and condensation cycles leave a haze on exterior glass that's particularly noticeable in spring sunlight
• Tree pollen: Guelph's many mature trees produce heavy pollen in April–May that coats exterior surfaces. Cleaning after peak pollen season (late May) is ideal timing
• Winter grime on tracks and sills: Interior sills accumulate condensation residue and debris through a long Guelph winter — spring is the right time to address it thoroughly

Why Fall Cleaning Makes Sense

A fall cleaning in September or October:

• Removes summer's accumulated dust, insect debris, and sprinkler mineral deposits
• Ensures maximum natural light through clean glass heading into Guelph's darker winter months
• Allows inspection of window seals and frames before cold weather sets in — a good window cleaner will flag failing seals or damaged caulking while they have every window in view

When to Clean More Frequently

Some Guelph properties benefit from cleaning more than twice a year:

• Homes near the Speed River or Stone Road with heavy tree pollen exposure — bird droppings and sap are perennial issues
• Homes on arterial roads (Stone Road, Gordon, Edinburgh, Hanlon) — traffic exhaust and road spray accumulate faster
• Homes with dogs — nose prints and pawing on lower windows are constant
• Properties near construction — dust and concrete particles etch glass if left too long

Signs It's Been Too Long

• Noticeable film or haze visible from inside, even with interior lighting
• Water spots that don't wipe away with a cloth (mineral deposits requiring chemical removal)
• Bird droppings that have dried and hardened (acidic; starts etching glass surface if left)
• Visible mould or mildew in window tracks or on gaskets
