Condensation creeping across your windows might seem like a small bother, but let it linger and you’re courting trouble—damp patches, mould creeping up sills, and even health risks, as the Government warns.
Warm indoor air clashing with chilly glass can turn your home into a breeding ground for respiratory nasties, and it’s not just ugly—it’s a proper hazard. Thankfully, you don’t need a fat wallet to fight back, says Allan Reid from Art Windows and Doors.
“Condensation is a frequent problem, particularly during winter when the contrast between indoor and outdoor temperatures is at its peak,” he tells The London Property News, flagging the stakes. “Though it might appear minor, the long-term impact can be considerable. If left unchecked, condensation can encourage mould growth, potentially harming both your property and your health.”
Skip the pricey dehumidifiers—Reid’s got thrifty fixes up his sleeve.
“You likely already have a natural dehumidifier at home – bicarbonate of soda,” he says. “Simply placing small bowls of it on windowsills can help absorb excess moisture in the air. Over time, you’ll see it harden, a sign that it’s working effectively. It’s an inexpensive and widely available solution, perfect for smaller rooms where it can help reduce humidity and prevent condensation.”
For bigger spaces, he reckons rock salt’s your mate—“naturally draws in dampness and can handle a higher volume, making it particularly useful in bigger rooms where condensation is an issue.”
Showering habits matter too.
“If you frequently have long, hot showers, the excess steam can significantly raise indoor humidity levels,” Reid cautions.
His fix? “Short and use warm rather than very hot water” showers, plus crack a window or flick on the extractor fan after. Then there’s a green twist—plants like peace lilies and Boston ferns.
“Naturally help absorb excess moisture from the air” and “assist with humidity control,” he says, while they “enhance the air quality in your home by removing pollutants.”
Don’t sleep on ventilation either.
“Allowing fresh air to circulate, even in winter, can help maintain a healthier indoor environment,” Reid advises.
“Opening windows for at least an hour lets out moisture-laden air and brings in drier outdoor air.”
Keep your heating sensible and stay sharp for trouble signs
“Water stains or mould, particularly in areas with poor ventilation,” he warns. “If left unaddressed, mould can become much harder to remove and may lead to both household damage and potential health concerns.”
If it’s too much, call in the pros—they can “identify the root cause and recommend solutions, which may include resealing window panes or even refitting windows to prevent further moisture build-up,” he suggests.
These budget tricks could be the difference between a mouldy mess and a fresh, healthy pad.
