Spring may be just around the corner, but in Ottawa, the battle with window condensation isn’t over yet. As the days warm up and the nights stay chilly, many homeowners start noticing foggy windows and excess moisture. Frustrating reminders that condensation isn’t just a winter problem.
At Canadian Comfort, we've spent over 55 years helping Ottawa residents enjoy clear, dry windows year-round. With our expertise in high-quality, made-in-Canada windows, we’re here to help you understand why condensation happens and how to keep it under control.
Understanding Window Condensation
Window condensation happens when warm, humid air comes into contact with a cooler surface, causing water droplets to form. In Ottawa’s climate, this is especially common during seasonal transitions when temperatures fluctuate dramatically between day and night. While a little condensation isn’t necessarily a problem, excessive moisture can lead to bigger concerns like mould growth, damaged window frames, and wood rot issues that no homeowner wants to deal with.
Prevention Strategies
Improve Ventilation
One of the simplest and most effective ways to reduce window condensation is by improving airflow in your home. Even in cooler months, cracking a window for a few minutes daily helps fresh air circulate and keeps humidity levels in check. In moisture-heavy areas like kitchens, bathrooms, and laundry rooms, exhaust fans play a crucial role in quickly removing humid air before it settles on your windows.
Control Indoor Humidity
Maintaining optimal indoor humidity levels (between 30-50%) can significantly reduce window condensation. Consider using a dehumidifier, especially in basements or other damp areas of your home. Our North Star windows are designed to help maintain consistent indoor temperatures, which can aid in humidity control.
Upgrade to Energy-Efficient Windows
Investing in high-quality, energy-efficient windows can make a world of difference. At Canadian Comfort, we offer a range of options designed to combat condensation:
Triple-Glazed Windows: These provide superior insulation, keeping the inner pane warmer and less prone to condensation.
Low-E Window Coatings: This special coating reflects heat back into your home, keeping the glass surface warmer.
Casement Vinyl Windows and Awning Windows: These styles allow for better airflow when opened, helping to reduce moisture buildup.
Proper Window Coverings
While curtains and blinds are great for privacy, they can trap moisture against the windowpane. Ensure your window coverings allow for air circulation. Consider using shorter curtains or blinds that don't completely cover the glass for bay vinyl windows or bow vinyl windows.
Addressing Existing Condensation
If you're already dealing with window condensation, don't worry. There are steps you can take to address the issue:
Wipe Down Windows
Regularly wiping down your windows with a clean, dry cloth can help remove excess moisture. This is particularly important for single-hung tilt-in vinyl windows and double-hung tilt-in vinyl windows, which can be easily cleaned from the inside.
Check for Proper Sealing
Inspect your windows for any gaps or cracks in the sealing. Our combination vinyl windows and picture windows are designed with superior sealing technology, but over time, all windows may need some maintenance. If you notice any issues, it might be time for a professional inspection.
Consider Window Replacement
If your windows are old or consistently problematic, it might be time for an upgrade. Our double slider lift-out windows and single slider lift-out windows offer excellent ventilation options, while our double slider slide-&-turn windows provide easy access for cleaning and maintenance.
