No single date suits every house, but there is a sensible order of jobs through the year. This planner ties each season's checks to Ontario cues such as the spring thaw, seed drop and leaf fall, shows how to adjust it for your own lot and explains where the wash itself fits.

How this planner works
The planner runs on cues, not dates, because a late spring or an early frost moves everything. It sorts the year into three kinds of job: looking (short inspections), preventing (clearing, trimming and drainage) and washing (the actual service). Most of the year is looking and preventing. The wash is a decision you make when the evidence says so.
Each check takes about fifteen minutes. Keep one phone folder for the photos so year-on-year comparisons are easy, and copy the table into your calendar as reminders for the checks, not for the wash.
The year at a glance
| Period | Cue to watch for | What to do | Wash decision |
|---|---|---|---|
| Late winter, after the thaw | Snow gone, walls drying | Walk all four sides. Note salt film, ice-dam stains, loose trim and roof streaks through binoculars | Not yet. Nights are still freezing |
| April to mid May | Nights above freezing, buds opening | Clear eavestroughs, trim back branches and shrubs, repair caulk and paint on dry days | Book a slot if a problem wall needs one |
| Late May to June | Maple seed pods and pollen mostly down | Wash walls and trim if triggers showed up, then clean windows | Good window for a spring wash |
| July and August | Humid weeks, heavy dew | Spot-check the shadiest wall after wet spells and keep sprinklers off the siding | Only for fast-growing spots |
| September to early October | Cool nights, leaves still on | Second walk-around and photo comparison | Decide on a fall wash while days are mild |
| Late October to November | Leaf drop | Clear eavestroughs once maples and oaks are mostly bare, and sweep leaves from wall bases | No wash. Focus on debris |
| December to February | Freezing weather | Log what you saw and list spring jobs | No wash |

Three dials that adjust the planner to your house
- Shade. Homes under mature trees, or beside a ravine, should add a check after each wet month. Open, sunny lots can keep to the two big walk-arounds.
- Material. Painted wood, stucco and porous brick hold moisture, so act earlier on them. Smooth vinyl can wait a little longer.
- Water. Walls beside a downspout, a sprinkler or a hedge stay wet longer. Fix the water source first, and expect those walls to need more attention.
Turn each dial up or down by one notch, and you have a schedule that fits your house instead of an average one.
When the weather disagrees with the plan
Do not chase a date. A wash needs the right conditions.
- Temperature. Keep the air comfortably above freezing while the mix is on the wall and for several hours afterwards. Cleaning mixes work more slowly in the cold, and rinse water can freeze on steps and walls. Product labels often give a minimum temperature.
- Wind. Calm days keep mist off the neighbours' plants and cars.
- Rain. Dry weather while the mix is on the wall matters, and a soaked lawn or thawing ground will not absorb rinse water.
- Spare day. Keep one free, and check the forecast at weather.gc.ca before committing.
If you miss the spring window, nothing is lost. Growth is not on a deadline, and early fall works as well. Frost is the only hard stop.
A one-line log that makes next year easier
After each walk-around, write one line per wall with four things: the date, the wall or roof slope, its condition and the action you chose.
A spring entry might read: north wall, faint green tint at the base, watch and recheck after the June rains. An early fall entry might read: roof, north slope, two new streaks, ask for a roof assessment.
Two or three rounds of this tell you how long your shadiest wall takes to green, which is the most useful number in the whole planner. The exterior maintenance schedule for Ontario shows where it sits alongside gutters, windows and other seasonal jobs.
Where the wash itself fits
How often the wash itself is needed varies widely, from every year on a damp, shaded lot to much less often on a sunny one. When a check says it is time, the next step is a free written quote. Soft washing at D&D is priced from $350 for a typical Kitchener-Waterloo home. The spring exterior cleaning checklist covers the jobs that go alongside it.
Key Takeaways
- The planner runs on Ontario cues such as thaw, seed drop, humid spells and leaf fall, and most of the year is inspection and prevention, not washing.
- Spring washing works best after seed pods and pollen have mostly fallen, and fall washing works while days are mild and above freezing.
- Shade, material and water sources are the three dials that adjust the planner for your own lot.
- Log one line per wall after each check, since the time your shadiest wall takes to green is the number that sets your schedule.
