Understanding Window Condensation in Calgary Homes
Why Windows Develop Condensation Problems
Types of Window Condensation
Exterior Window Condensation
Less common but still problematic, exterior condensation occurs when outdoor humidity contacts cold window surfaces, typically during spring and fall transition periods when overnight temperatures drop below the dew point.
Between-Pane Condensation
The most serious type occurs between double or triple-pane glass units, indicating failed window seals that allow moisture infiltration into sealed spaces. This type requires immediate professional attention to prevent permanent window damage.
Interior Window Condensation
The most common type occurs on the inside surface of windows when indoor humidity levels are high and window surfaces are cold. This typically happens during Calgary’s heating season when the temperature difference between indoor and outdoor air is greatest.
Interior condensation often appears first on bedroom and bathroom windows where humidity levels are naturally higher, and on north-facing windows that receive no direct solar heating to warm the glass surface.
Calgary-Specific Contributing Factors
Extreme Temperature Differences
Calgary’s winter temperatures often drop to -30°C while indoor temperatures remain at 20-22°C, creating 50-degree temperature differences across window glass. This extreme differential makes condensation almost inevitable without proper window insulation and humidity control.
Chinook Temperature Swings
Dry Winter Air and Indoor Humidification
New Home Construction
Newer Calgary homes often have higher insulation levels and tighter construction that can trap humidity indoors, concentrating moisture problems on windows if ventilation isn’t adequate.
Health and Structural Risks
Window condensation creates ideal conditions for mold and mildew growth around window frames, can damage wood window components through constant moisture exposure, stains and damages interior paint and wallpaper, and indicates humidity levels that may be unhealthy for occupants, particularly those with respiratory sensitivities.

How to Fix Window Condensation: Professional Solutions
Comprehensive Approaches to Eliminate Moisture Problems
Immediate Condensation Control
Surface Temperature Management
Installing storm windows or window insulation film increases interior glass surface temperatures, reducing the likelihood of condensation formation. These solutions are particularly effective for older single-pane windows common in Calgary's heritage neighborhoods.
Window treatments like cellular blinds or insulated curtains create air barriers that keep warm indoor air away from cold window surfaces while providing additional insulation that raises surface temperatures.
Humidity Level Control
Professional humidity testing determines optimal indoor humidity levels for your specific home and window configuration. Generally, Calgary homes need 30-40% relative humidity during winter months to maintain comfort while preventing condensation.
Mechanical ventilation improvements including bathroom and kitchen exhaust fans, whole-house ventilation systems, and controlled air exchange help maintain proper humidity levels throughout the home.
Advanced Window Solutions
Window Insulation Upgrades
Modern Low-E glass coatings significantly reduce heat transfer through windows, keeping interior glass surfaces warmer and reducing condensation likelihood. These coatings are particularly effective in Calgary's extreme climate conditions.
Triple-pane window systems provide maximum insulation, virtually eliminating condensation problems while dramatically improving energy efficiency. The investment often pays for itself through reduced heating costs and eliminated condensation damage.
Seal and Weatherstripping Improvements
Comprehensive air sealing around windows prevents cold air infiltration that can create localized cold spots and condensation. Professional installation ensures effective sealing while maintaining proper ventilation.
Ventilation System Integration
Whole-House Ventilation
Heat Recovery Ventilators (HRV) or Energy Recovery Ventilators (ERV) provide controlled air exchange that maintains indoor air quality while minimizing energy loss. These systems are particularly valuable in Calgary’s tight, well-insulated homes.
Proper ventilation design ensures fresh air circulation without creating drafts or uncomfortable temperature variations that can worsen condensation problems.
Professional Assessment and Solutions
Our comprehensive condensation assessment includes thermal imaging to identify cold spots and air leaks, humidity testing throughout your home to determine optimal control strategies, ventilation analysis to ensure proper air exchange rates, and window performance evaluation to determine upgrade benefits.
Based on assessment results, we provide customized solutions that may include window insulation improvements, ventilation system upgrades, humidity control recommendations, and window replacement when necessary for optimal performance.
Localized Humidity Control
Strategic placement of exhaust fans in high-humidity areas like kitchens, bathrooms, and laundry rooms removes moisture at its source before it can migrate to windows and cause condensation.
