7 Ways to Avoid Window Condensation

Cleaning Mold from Windows

Excessive condensation is a problem that many homeowners face at one time or another. It occurs when there is too much humidity in the house or when warm air touches cold surfaces.

Condensation forms when excess moisture builds up and doesn’t have anywhere to go. So it settles on different surfaces, such as windowsills, walls, and ceilings, causing mold formation.

How can you avoid window condensation? Let’s look at 7 key approaches.

  1. Proper Window Installation
  2. Ensure Excellent Ventilation in the Laundry Room
  3. Dry Clothes In Your Backyard
  4. Close Bathroom and Kitchen Doors
  5. Wipe Down Windowsills
  6. Use Lids While Cooking
  7. Consider a Dehumidifier

Without further ado, let’s talk about each.

Proper Window Installation

Window condensation often occurs when windows are improperly installed. They allow cool air to seep in and settle on the warm window frames and windowsills. Thus condensation occurs. If you notice condensation appearing around the joint between glass and window frames or between the window frame and the wall, call the window repair specialists.

Ensure Excellent Ventilation in the Laundry Room

Your washing machine produces over half a gallon of water each time it runs a cycle. This water is emitted into the air. It settles on surfaces, creating condensation. To avoid this problem, make sure the area is properly ventilated. The same is true for your kitchen.

Dry Clothes In Your Backyard

Whenever the weather allows, try to dry your clothing outdoors. Wet clothes create excess moisture buildup wherever you hang them to dry. If the weather is cold, hang your wet clothes in a closed bathroom or basement with open windows.

Close Bathroom and Kitchen Doors

The majority of condensation occurs in kitchens and bathrooms. While ensuring proper ventilation in these areas, don’t forget to close doors when cooking or taking a shower. This way moisture doesn’t have an opportunity to spread all over your house.

Wipe Down Windowsills

If you see moisture settling on your windowsills or other cool surfaces in your home, wipe it down immediately. Otherwise, it could provide an excellent environment for mold growth.

When you book seasonal window cleanings, ask the experts to inspect your windows for cracks and damages to ensure no cool air comes from the outside.

Use Lids While Cooking

When you cook, moisture evaporates from your pans and pots. If you keep lids on, you reduce the chances of moisture settling on windowsills. Meanwhile, such an approach can keep your kitchen windows clean longer.

Professional window cleaners often note that kitchen windows and windowsills are the dirtiest and most prone to mold growth.

Consider a Dehumidifier

If you suffer from high humidity levels in your home, consider investing in a dehumidifier. It could help reduce condensation formation on different surfaces. It’s vital to replace dehumidifier filters regularly to avoid mold formation inside the unit and mold spores spreading through the air.

Closely following sources of condensation could help you avoid such unfortunate consequences as mold formation and damaged surfaces.
