What’s the Best Temperature and Time of Year to Clean Exterior Windows in Toronto?
Northern Touch Window Cleaning, a trusted Toronto-based company specializing in exterior window cleaning, recommends choosing the right temperature and seasonal timing to prevent streaks, smudges, and long-term glass degradation. The outside temperature and sunlight exposure can dramatically affect both the effectiveness and safety of your window washing experience.
Cleaning outside windows in either extreme cold or direct sun often leads to poor results. Too much heat causes water to evaporate too quickly, leaving behind residue, while sub-zero temperatures may result in frozen runoff and brittle seals.
What Weather Is Best to Wash Windows Outside?
Ideal window cleaning weather is cool, dry, and overcast. This is when water doesn’t evaporate too fast or freeze prematurely. According to pros at Northern Touch, the best temperature to wash outside windows is between 5°C and 20°C (41°F–68°F)—warm enough to prevent freezing, but not hot enough to cause flash-drying.
Should You Use Hot or Cold Water for Cleaning Windows?
For outside windows, professionals use lukewarm to mildly hot water during spring or fall cleanings. This helps break down dirt without risking thermal shock to the glass, especially in colder temperatures. In winter, however, overly hot water can crack frigid windows, so technicians use warm solutions balanced with anti-freeze detergents.
Can You Wash Windows in Cold Weather?
Yes, but with caution. Washing windows in cold weather, especially during Toronto’s winter, demands specialized techniques. Northern Touch Window Cleaning uses temperature-adapted cleaning solutions that prevent freezing and avoid thermal shock to glass panes.
In temperatures near or below 0°C (32°F), water can freeze before it’s wiped away, leading to hazardous ice buildup on glass or window frames. More importantly, condensation from indoor heat clashing with the cold exterior may cause fogging or streaks from the inside, creating the illusion of a dirty window even after cleaning.

H2: Fall vs. Spring: What’s the Best Season for Exterior Window Cleaning in Toronto?
Between fall and spring, fall wins for durability and spring for clarity.
Fall window cleaning in Toronto ensures windows stay clear through the snowy months, reducing the buildup of salt residue, rain spots, and urban grime that accumulates during winter.
Fall also offers stable temperatures—usually between 8°C and 16°C (46°F–61°F)—which are perfect for exterior window washing.
Spring window cleaning, on the other hand, clears away winter’s debris. It’s ideal for freshening up views and boosting curb appeal as the sunlight increases. However, demand surges during this season, meaning fewer appointment slots and potentially rushed service if not booked early.
When Should You Book an Exterior Window Cleaning in Toronto?
For crystal-clear results and minimal risks, Northern Touch recommends the following:
| Season | Best Use Case | Temperature Range | Notes |
|---|---|---|---|
| Spring | Remove winter debris and boost clarity | 5°C–18°C (41°F–64°F) | Book early to avoid peak demand |
| Summer | Avoid unless early morning or cloudy | 18°C–25°C (64°F–77°F) | Risk of streaking in high heat |
| Fall | Long-lasting results into winter | 8°C–16°C (46°F–61°F) | Best for prepping windows pre-snow |
| Winter | Possible with precautions | ≥ -2°C (28°F) | Requires specialty tools and anti-freeze solution |
Fall and spring consistently offer the best balance between service quality and environmental safety.
