Winter is hard on glass. By spring the outside of your windows wears a film of road salt, sand and furnace exhaust, and the low sun shows every streak of it. That's why spring is the busy season for window cleaners, with fall as the other good slot before the cold makes water work miserable. Book early if you want April rather than June.
A proper visit covers more than the panes. Screens come out and get washed, tracks and sills get wiped, and on older houses the storm windows come down or go back up. Sealed double and triple glazing has one limit worth knowing. Fog between the panes means the seal has failed, and no squeegee can reach it.
Ask who's actually climbing the ladder and whether they're covered. In British Columbia, WorkSafeBC warns that you could be held jointly liable for premiums a hired contractor doesn't pay. It lets you pull a free clearance letter online before the crew shows up.
Our listings show what each window cleaner says on its own website: what a visit includes, its hours, and what customers report in public reviews. Pick your province, then your city, to find crews that work near you.
Either can do a good job, and plenty of crews carry both. A water-fed pole washes upper floors from the ground with filtered water that dries without spots, and it keeps ladders off soft spring lawns. A squeegee gives a crisp finish on glass you can reach. Neither likes a hard frost. Water sets on the glass and in the hose, so many crews put the pole away until the thaw.
A clean each spring and another each fall suits most houses here. The spring visit takes off salt spray and grit from winter roads. The fall visit clears pollen, bugs and cottonwood fluff before the windows stay shut for months. Glass facing a busy street or a building site gets dirty faster. A sheltered back window can skip a round and nobody will notice.
Not always, so get the list in writing. Some quotes cover the glass and nothing else. A full visit takes screens out, washes them and wipes the tracks and sills. Older houses add storm windows, and taking them down or putting them up is extra labour that a cheap quote quietly leaves out. Mention any sash that sticks or tilts in before the crew arrives.
Inside, any day you like. Outside, it depends on the cold. Below freezing, water and soap can ice up on the glass before the squeegee clears it, and a pole's hose can freeze solid. Some crews add an antifreeze product to the bucket and keep working on milder days. Others close for the season. Ask before you book a date in January, and expect a rain check.
A separate trade with its own rules. Condo towers get cleaned from boatswain's chairs, suspended platforms or rope access, not ladders. In Ontario, a window cleaning regulation makes the building owner keep sketches of the roof anchors and have them inspected. The contractor must also phone a provincial inspector before chair or platform work begins. On a house, a crew that wants to stand on a balcony rail is a crew to send home.
