Why Does Condensation Happen?
Condensation forms when too much moisture in the air meets cold window surfaces. This often happens in modern, energy-efficient homes that trap heat but also trap humidity. While this may seem harmless, it can damage your windows, walls, and even furniture.

What Causes Excess Moisture?

Everyday activities like cooking, showering, and laundry add water vapor to the air. This moisture gets trapped in modern “tight” homes, leading to condensation issues. Did you know:

• A family of four can add 18 gallons of water vapor to the air each week through daily activities?

Keep Humidity at the Right Level

Here’s a guide for maximum indoor humidity based on outside temperatures:

Staying within these limits will help reduce condensation while keeping your home comfortable.

7 Easy Steps to Control Condensation

1. Install Storm Windows or Double Glazing: These prevent cold air from meeting moist indoor air.
2. Turn Off Humidifiers: Avoid using furnace humidifiers or other devices that add moisture.
3. Improve Ventilation: Open vents or louvers in crawl spaces and basements to improve airflow.
4. Run Exhaust Fans: Use fans in kitchens and bathrooms more frequently, especially during and after cooking or showering.
5. Open Fireplace Dampers: This allows moisture-laden air to escape more easily.
6. Ventilate Daily: Open windows for a few minutes each day to bring in fresh, dry air and let out moist air.
7. Check Attics and Crawl Spaces: Ensure proper ventilation to prevent moisture buildup.

What About Temporary Condensation?

If your home is newly built or recently remodeled, materials like wood and plaster release moisture into the air. This can cause temporary condensation, which usually disappears after the first heating season.
