How to Prevent Window Condensation

Window condensation is a common issue in many homes, especially during colder months. It not only blocks your view but can also lead to mold, rot, and long-term damage to your windows and walls. Fortunately, there are simple and effective ways to minimize excess moisture in the air and reduce condensation. Here’s how to prevent window condensation and keep your home dry, healthy, and comfortable.

Bathroom Tips

Bathrooms are one of the primary sources of indoor humidity. Here’s how to manage moisture effectively:

• Use an exhaust fan: Always run the exhaust fan while showering or bathing, and keep it running for at least 30 minutes afterward. This helps remove steam before it settles on surfaces.
• Ensure proper ventilation: Exhaust fans should vent directly outside, not into the attic. Check regularly for blockages or weak airflow.
• Wipe down surfaces: After every shower or bath, squeegee and dry the walls and surfaces around the tub or shower to prevent water buildup.
• Fix leaks and damage: Repair cracked tiles, damaged grout, or deteriorated caulking promptly to prevent moisture from seeping into walls.
• Address plumbing issues quickly: Even minor leaks can add significant moisture over time.
• Clean visible mould: Use unscented dish soap and water to scrub away any mould you find.

Kitchen Tips

Cooking generates a lot of moisture, especially when boiling water or frying.

• Use the range hood: Always use your kitchen exhaust fan when cooking, preferably on the highest setting. Ensure it vents outdoors.
• Cook smart: Using the back burners can help the range hood capture more steam and smoke.
• Maintain your fan: Clean and inspect the hood regularly to ensure effective airflow.

Laundry Room Tips

Appliances in the laundry room can be another source of humidity. Proper use and maintenance help reduce excess moisture.

Washing Machine

• Leave the door open between uses to let the interior dry and prevent mould buildup.
• Ensure that drain pipes or hoses don’t splash or leak. Pipe extensions can help direct water more effectively.
• Check for leaks around hoses and connections.

Clothes Dryer

• Make sure your dryer vents to the outside, not indoors or into a crawlspace.
• Seal duct joints with foil tape to prevent warm air and lint from escaping.
• Clean the lint tray after every load.
• Regularly inspect and clear the outside exhaust vent to ensure it’s not blocked by lint, snow, or debris

Managing Window Condensation

Even with ventilation, some moisture may still find its way to your windows. Here’s how to keep it under control:

• Maintain proper humidity: Keep your indoor relative humidity between 30% and 50%. A hygrometer can help you monitor this.
• Use ventilation systems: Run bathroom and kitchen exhaust fans regularly to reduce indoor moisture.
• Let warm air circulate: Keep window coverings open during the day. Heavy curtains can trap cool air near the glass, increasing condensation risk.
• Clear airflow paths: Don’t block baseboard heaters or vents with furniture. Keep doors open to promote good air circulation.
• Wipe down window frames: Dry any condensation on your windowsills daily to prevent mould and water damage.
• Remove humidifiers: If you’re experiencing ongoing condensation, try unplugging humidifiers to reduce indoor humidity levels.
