When is the best time to get windows cleaned?
As fortunate as we are to live in the beautiful Pacific Northwest, this climate brings rain, pollen, smoke, and constant moisture - so timing your window cleaning makes a big difference.
Keep reading to find out the best time to get your windows washed!
Spring (March–June)
Spring is prime time. It clears away winter grime, tree sap, and heavy pollen. You also get brighter indoor light right as the days get longer.
Fall (September–November)
Fall cleans off summer dust and wildfire residue and gets your home ready for winter. Clean glass also helps maximize natural light during the darker months.
Why These Seasons Work Best
Mild temperatures — detergents work properly and don’t evaporate too quickly.
Less direct heat — reduces streaking and “flash drying.”
Safer conditions for both exterior and interior window cleaning.
What to Avoid
Mid-summer afternoons: too hot → streaky results.
Freezing conditions: solution won’t behave properly.
Storm days: light rain is fine, but heavy wind/rain isn’t ideal.
Bonus Myth-Buster: Rain Doesn’t Make Clean Windows Dirty
Rainwater itself is clean. If your windows are freshly washed, rain won’t ruin them.
Dirty windows + rain = spots. Clean windows + rain = still clean.
Final Thought
Briteworx services homes in the Metro Vancouver, Tri-Cities (Coquitlam, Port Coquitlam, Port Moody) and across the bridge towards Surrey and Langley. Scheduling a window cleaning in spring and fall keeps your glass looking clear year-round and protects your frames, seals, and screens from long-term buildup.
Additionally, we highly recommend getting your exteriors professionally cleaned if you’re planning on listing your home. You can read more here about how a clean curb appeal can increase a home’s perceived value by up to 5%! That is a $50,000 swing on a $1,000,000 home!
