The Exterior Cleaning Calendar: What to Do Each Month
Exterior cleaning is far easier when it is a rhythm through the year rather than a panic when something looks bad or fails. Spreading the jobs across the seasons keeps the home protected, avoids the spring rush, and means no single big backlog. Here is a simple month-by-month guide for a Lower Mainland home.

Winter and early spring
The wet, quiet months are a good time for the cleaning that protects the home through winter and does not need dry weather: roof soft washing and gutter checks matter most here, since the system is under the heaviest load. It is also the easy-to-book off-season. Early spring is when the winter's grime becomes visible and planning the spring refresh begins.
- December to February: roof soft wash and gutter checks in the off-season; keep downspouts draining through storms
- March: assess the winter's algae and moss; book the spring refresh before the rush
Spring and summer
Spring is the big reset, clearing the winter's growth off the whole envelope, and it is the busy season, so booking ahead helps. Summer's dry window is the time for the finishing jobs that need to cure or bond, deck and fence staining, concrete sealing, paver re-sanding, and for the outdoor-living surfaces you most want clean for the season.
- April to May: full spring refresh, roof, gutters, house wash, windows, walkways
- June to August: decks, fences, patios and pool areas; staining and sealing in the dry weather; window cleaning after pollen season
Fall
Fall is the most important preparation window of the year, getting the home ready for the wet season before it arrives. The gutters are the priority once the leaves are down, along with clearing roof moss and the walkway slip hazards before the dark, wet months.
- September to October: pre-winter roof and walkway cleaning; book gutter cleaning timing
- November: gutters cleared and flushed after the leaf drop, before the first freeze; confirm downspout drainage
