Winter is a true test for windows. Large temperature differences, moisture, and cold winds challenge their durability and insulation. Without proper care, windows may develop drafts, mold caused by excess moisture, and higher heating bills due to heat loss.
Drafts – why do they appear?
Drafts usually occur when seals are worn out, frames have gaps, or windows are poorly adjusted. In winter, this leads to discomfort and higher energy consumption.
What to do:
-
Check the seals – if the rubber is hard or cracked, replace it.
-
Adjust the closing pressure – in winter windows should close tighter, in summer slightly looser.
-
Add extra sealing strips or insulation tape if needed to reduce airflow.
Mold and moisture around windows
When warm indoor air meets cold glass, condensation forms. If not removed, it can create damp conditions and lead to mold.
Solutions:
-
Ventilate rooms regularly, even in winter – short, intensive airing reduces humidity.
-
Use a dehumidifier if moisture is excessive.
-
Clean frames and seals to prevent dirt from trapping moisture.
Practical winter care tips
-
Wash windows before the cold season – clean glass lets in more light and retains warmth better.
-
Lubricate hinges and moving parts with silicone oil to avoid freezing or sticking.
-
Check window sills and drip caps – they should direct water away from the frame and wall.
Conclusion
Winter window maintenance is not just about appearance but also about health and efficiency. Properly maintained windows keep your home warm, prevent mold growth, and help reduce heating costs.
