Indoor moisture management involves identifying the causes of condensation to prevent mold growth and health issues. Condensation on interior glass typically indicates high humidity and poor ventilation, while moisture between panes suggests a seal failure in double glazing. Methods for managing humidity include mechanical ventilation systems (VMC), portable dehumidifiers, and cross ventilation. During winter, short bursts of intense ventilation may be more effective than leaving a single window slightly open. To manage heat during heatwaves, aluminum foil can be used on windows to deflect solar radiation. As temperatures drop in autumn, the temperature gap between interiors and exteriors can increase condensation. Experts from Lifestyle Blinds note that as outdoor temperatures drop, warm indoor air meets cold glass, causing moisture to collect on surfaces. To mitigate risks of rot and mold, homeowners are advised to regularly wipe condensation from windows, sills, and frame edges using a squeegee or microfibre cloth. To prevent windows from fogging, applying a small amount of dish soap to cleaned glass can act as an anti-fogging agent by lowering the surface tension of water. agent. For ventilation, rather than leaving windows slightly cracked—which can chill walls and encourage condensation—performing short, intense sessions of approximately ten minutes is more effective. This allows cold, dry air to rapidly replace moist air without deeply cooling the building structure. Other preventative measures Additional maintenance strategies include using extractor fans, covering pans while cooking, and ensuring laundry is dried in well-ventilated areas. Household items such as table salt, baking soda, Neil McKenzie of Halton Stairlifts suggests using coarse salt in small containers on windowsills to absorb moisture. For PVC or animal litter wooden windows, homeowners can also be placed use a 4mm Allen key to turn eccentric pins on windowsills the window sash to act as moisture absorbers. ‘winter mode’ to ensure a tighter seal. Keeping curtains open at night can also assist by allowing air circulation around the glass.
