WITH freezing temperatures and snow hitting Scotland this week, many homeowners are dealing with persistent issues of dampness and condensation. It's a common problem in the winter months and with no sign of sunshine returning anytime soon, people have already started looking for ways to keep their homes safe. Condensation on windows occurs when warm, moist air comes into contact with cold surfaces.

And since windows are often colder than insulated walls, condensation is more likely to occur on them. This could then drip onto surfaces and cause mould to form - and this can be dangerous to our health if left untreated. It also looks awful and can be a pain to get rid of once it starts to spread. Luckily one expert has revealed how you can rid your windows of condensation without having to splurge on a dehumidifier.

Dehumidifiers can be expensive to buy and can also result in high energy bills if they're left running constantly. Condensation is a frequent problem... If left unchecked, it can encourage mould growth, potentially harming both your property and your health. He said: “Condensation is a frequent problem, particularly during winter when the contrast between indoor and outdoor temperatures is at its peak.

"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. "However, if you don’t have a dehumidifier or don’t want to splurge on one, there are easy ways to prevent condensation from seeping into your windows.”. You might not realise it, but you could actually have a built-in dehumidifier already in your home.

Bicarbonate of soda works in the same way and can be used to get rid of condensation. The experts say: “You likely already have a natural dehumidifier at home - bicarbonate of soda. "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 larger rooms like living rooms or dining rooms, you might need something stronger than bicarbonate of soda. This is where rock salt comes in - experts say these are another good alternative for getting rid of extra moisture in the air. Allan said: “For larger, less confined spaces, rock salt is a great option for tackling excess moisture. "It naturally draws in dampness and can handle a higher volume, making it particularly useful in bigger rooms where condensation is an issue.

"You can pick some up at your local supermarket or order it in bulk online.”. Condensation can also be caused by cooking, showering, washing up, doing laundry, gas or using paraffin heaters. Which means condensation is most commonly found in bathrooms or kitchens as this is where there is more humidity. So in a bid to help get rid of this issue, experts suggest taking shorter showers in a bid to reduce the amount of hot steam it creates.

They explained: "If you frequently have long, hot showers, the excess steam can significantly raise indoor humidity levels. "It’s best to keep showers short and use warm rather than very hot water. "Make sure to ventilate the bathroom afterwards - either by opening a window or switching on an extractor fan - to help clear the moisture and prevent damp problems.”. ALLAN also shared his top piece of advice on how to spot the first signs of dampness in your home.

He said: "Keep an eye out for signs of excess moisture, such as water stains or mould, particularly in areas with poor ventilation. "If left unaddressed, mould can become much harder to remove and may lead to both household damage and potential health concerns. "However, if the problem becomes too severe to manage on your own, it's best to contact a professional. "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.”.

Most people know that some indoor plants can make a room more humid - but did you know other plans can actually remove moisture from the air?. Having a few of these humidity-absorbing plants can make a huge difference when you're battling condensation. The experts suggest: “Few people realise that certain plants, such as peace lilies and Boston ferns, naturally help absorb excess moisture from the air.

"You can find these plants at most home and garden shops, and they not only assist with humidity control but also improve the air quality in your home by removing pollutants.”. Putting the heating on can not only result in high energy bills, but it can actually cause mould to form on areas like the walls or ceilings. This is because it can lead to moisture being trapped in the air. So homeowners have been urged to use it "sensibly" and also keep rooms ventilated at the same time.
