Window Condensation Prevention

Why condensation forms on windows and how to prevent it to avoid mold and moisture problems.

5 min read

Introduction

Window condensation is a common problem in Latvian homes, especially in autumn and winter. It's not just an aesthetic issue - prolonged condensation can cause mold growth, damage to wooden window frames, and health problems. Liepaja's coastal climate with high humidity makes this problem even more relevant.

Step by Step

  1. 1

    Ensure regular ventilation - open windows at least 2-3 times daily for 5-10 minutes, even in winter. Short intensive airing is more effective and economical than keeping a window slightly open for long periods. This allows moist air to escape without completely cooling down the room.

  2. 2

    Check and improve your ventilation system. In apartment buildings, make sure ventilation openings in the kitchen and bathroom aren't blocked. Hold a piece of paper against the opening - it should stick. If it doesn't, ventilation isn't working properly.

  3. 3

    Reduce moisture sources indoors. After showering or bathing, always turn on the fan or open a window. When cooking, use the range hood. Don't dry laundry in living spaces - use a drying room or well-ventilated area.

  4. 4

    Maintain optimal temperature in all rooms - at least 18-20 degrees C. Colder rooms promote condensation. Make sure radiators aren't blocked by furniture or curtains that prevent heat circulation near windows.

  5. 5

    Check window seals and glass units. If condensation forms between the glass panes - the sealed unit is damaged and needs replacement. If window frames are old and drafty, consider window replacement or installing additional seals.

Warnings

  • If condensation appears regularly and mold is already visible - act immediately! Mold can cause serious respiratory diseases, especially in children and allergy sufferers.
  • Don't completely close ventilation openings even if they cause drafts - this will lead to even bigger moisture problems.
  • Avoid excessive use of humidifiers - optimal indoor humidity is 40-60%.
