Crying Windows or How to Resolve the Condensation Issue?

Key Takeaways:

• The temperature difference between the inside of your home and the window glass causes condensation on windows.
• Solutions range from weatherproofing to HRV systems and window replacement.
• Ignoring condensation can lead to long-term issues like mould and moisture damage.

Condensation on windows is a widespread issue across Canada, affecting homes in all provinces. For instance, regions with extreme climates, such as the northern territories, can experience temperature fluctuations ranging from -40°C in winter to +30°C in summer. These dramatic temperature shifts can lead to a condensation increase of up to 50% on windows. However, regardless of the climate challenges, homeowners can take proactive measures to eliminate this problem and enhance their comfort. You can effectively manage indoor humidity and prevent condensation by implementing strategies like weatherproofing, installing HRV systems, and considering window replacements.

Weatherproofing: A First Line of Defense

Over time, even the best-installed windows can suffer damage from the elements. This can result in small tears or gaps in the window's lining, allowing more air to enter your home. When outside air mixes with the warmer (or cooler) air inside, the risk of condensation rises.

One quick fix to help reduce condensation is weatherproofing your windows. By adding weather stripping to the outside, you can minimize air leaks. Applying caulk to the non-movable parts can reduce airflow if you have single-pane windows.

While weatherproofing won’t solve the issue entirely, it’s a solid temporary measure that can help reduce condensation build-up and buy you some time before considering more permanent solutions.

HRV Systems: A Long-Term Solution for Indoor Humidity

If the condensation issue persists, it could be due to the humidity levels inside your home. One effective solution is installing an HRV (Heat Recovery Ventilation) system.

An HRV system uses a heat exchanger to balance the temperature and humidity inside your home. By reducing the humidity, condensation on your windows is minimized. When paired with adequately sealed windows, this can drastically improve the overall comfort of your home. HRV systems are highly energy-efficient and work seamlessly with your existing heating and cooling systems, making them a practical long-term investment.

One Winnipeg homeowner had been battling condensation for years. After investing in an HRV system, the moisture problems were drastically reduced, and they even noticed a drop in their energy bills during winter.

When to Consider Window Replacement

If your crying window problem persists even after trying home repairs, it might be a sign that your windows are too old and need replacing. Modern windows, particularly vinyl windows, installed by experienced professionals create airtight seals that block out external air completely, preventing condensation from building up.

Vinyl windows offer better insulation and lower thermal conductivity than traditional wood windows. This means they are less likely to experience condensation issues. They also resist moisture, preventing mould growth and requiring less maintenance over time.

Replacing your windows doesn’t just solve the condensation problem. It’s also an opportunity to choose windows that suit your home's needs better. For instance, casement windows might provide better ventilation if you’ve been struggling with poor airflow. Or, if you’re looking to add more style to your home, a bay or bow window can make a significant visual impact while improving energy efficiency.

Vinyl vs. Wood Windows

When choosing windows for your home, understanding the differences between vinyl and wood options can help you make an informed decision, especially regarding condensation resistance. Below is a comparison that highlights the key aspects of each type:

Vinyl windows are generally the better option for condensation due to their superior insulation, moisture resistance, and lower likelihood of condensation buildup. They provide a long-term solution that can help maintain a comfortable indoor environment while minimizing the risk of moisture-related issues. In contrast, while aesthetically appealing, wood windows may require more maintenance and are more susceptible to condensation and moisture damage if not correctly cared for.

How to Prevent Condensation on Windows: A Quick Recap

To help prevent condensation on windows, follow these tips:

• Weatherproofing : Add weather stripping or caulk to reduce air leaks.
• HRV Systems : Install a system to manage indoor humidity and reduce condensation.
• Window Replacement : Upgrade to airtight, energy-efficient windows for a long-term solution.
