Short answer
Yes. Interior windows can be cleaned any time of year, and exterior windows can be cleaned on dry winter days when temperatures are above freezing. We reschedule exterior work if it's too cold for water to dry without freezing.
What limits winter cleaning
The main issue is freezing. Water needs to dry, not ice up on the glass or on walkways below. Boise winters have plenty of mild, dry days — especially outside inversion stretches — so exterior cleanings are often possible with a little scheduling flexibility.
Why some people prefer it
Low winter sun shines straight through the glass and shows every streak, and inversions leave a gray film that makes houses feel darker. Winter is also a quieter time to book, and interior-focused cleanings are a nice reset after the holidays.
Holiday timing
Many customers clean windows in early November before guests arrive — and if you're also getting Christmas lights installed, it's easy to do both close together.
