Spring is the natural reset point after a Calgary winter. Here's a window-focused checklist covering what actually needs attention.

The Checklist

  • Exterior glass: road salt, sand, and hard water spots from months of snow and melt.
  • Window tracks: grit and debris that's built up all winter, often causing sticking.
  • Screens: if removed for winter, clean before reinstalling; if left on, check for tears from wind and weather.
  • Seals and caulking: a good time to spot cracks or gaps that formed over the freeze-thaw cycle — not a cleaning task, but worth noting while you're at it.
  • Interior sills: dust accumulation from a winter with windows closed and less air circulation near them.

Timing

Late April to May is typically the sweet spot — after the worst of the freeze-thaw cycle but before pollen season peaks.

Don't Forget Siding

If you have vinyl or Hardie board siding, spring is also the right time to address winter grime there — often bundled with window cleaning for a full exterior refresh.
