Painting your home—whether interior or exterior—is one of the best ways to refresh your space and boost curb appeal. But timing your project around the right season is just as important as choosing the right colour or finish. Below, we answer some of the most frequently asked questions about seasonal painting to help you plan effectively.
When is the best time of year to paint the exterior of my home in Ottawa?
Late spring through early fall—typically from May to October—is ideal for exterior painting in Ottawa. During these months, temperatures are warmer and more stable, with minimal rainfall and humidity. The best results occur when daytime temperatures are between 10°C and 25°C, with no drastic overnight drops.
Can I paint the outside of my house in the winter?
In most cases, exterior painting is not recommended in winter. Cold temperatures can affect paint adhesion, drying time, and final appearance. However, if you're in a pinch and using specialized cold-weather paint, consult with our paint experts to see what’s possible.
Is there an ideal season for interior painting?
Interior painting can be done year-round, but fall and winter are actually great times to tackle indoor projects. With lower humidity and consistent indoor temperatures, paint cures more evenly. Plus, painters tend to be less booked during colder months, so it's easier to schedule your project.
How does humidity affect painting?
High humidity slows down drying time and can lead to bubbling or blistering. This is especially important for interior painting during the summer and exterior painting after heavy rainfall. Aim for days with relative humidity below 70% for best results.
What should I do before painting in any season?
-
Check the weather forecast for several days ahead.
-
Prep surfaces thoroughly—clean, sand, and prime.
- Use quality tools and paint suited for the season.
- Consider using professional services if you're unsure.
