Mould and damp is the last thing any homeowner wants to deal with as the weather turns cold, but sometimes it can't be helped. So how can we get rid of such an unwelcome houseguest and how can people ensure it doesn't return?
Even though there isn't a solid answer, there are certain method homeowners can take up to mould-proof their house. According to Art Windows & Doors founder, Allan Reid, "while double glazing is effective in preventing some condensation, the colder conditions can, unfortunately, bring mould regardless."
However, there are a number of options to try out that could be right for you and your home to help tackle any unwanted mould. Below the double glazing expert has shared a variety of tips, starting with the rule everyone should follow to help reduce condensation in the first place, as reported by the Mirror.

Install an extractor fan:
Homeowners may want to look into getting an extractor fan installed - especially in rooms subject to excessive moisture like the bathroom and kitchen. Reid said: "You can install an extractor fan directly into a double-glazed window (and even single-glazed windows) for a significant reduction in condensation.
"This is particularly effective for rooms prone to steaming, such as kitchens and bathrooms, with cooking and showering leading to an increase in water vapour."
Replace the air tight seal:
He also mentions considering replacing the air-tight seal between your layers of glass is essential to prevent water vapour. He adds: "If the seal fails and the insulating gas is not present, the subsequent water vapour will reduce the lifespan of your windows and potentially lead to draughts and chilly air.
"Luckily, replacing an air-tight seal is often inexpensive, costing between £5 to £10 per window."
Ensure adequate ventilation:
Reid says it is important to have adequate ventilation in your home. "Whether you have single, double or triple-glazed windows, proper ventilation is always the best way to reduce condensation," he said.
"For double and triple-glazed windows, condensation between the layers of glass is indicative of a problem, such as the air-tight seal failing and letting the insulating gas out."
Trickle vents:
Reid says trickle vents can be fitted into all different types of window frames, including double and triple glazing, which are highly effective at aiding the circulation of air in your home, leading to a reduction in mould, condensation and dampness. "Unfortunately, some older homes may lack these features, but the units are mandatory when replacing windows as of 2022," Reid explains.
Keep an eye on varnish and paint:
Making sure you monitor the vanish and paint indoors is also another tip Reid claims helps. "If the paint around your windows is starting to chip, bulge or flake, this indicates a condensation problem," he said.
"Whether moisture is trapped underneath the paint or the varnish begins sweating during the colder months, this can exacerbate condensation problems further. In addition, paint can often hide dampness, which is caused by condensation. By ignoring the flaking paint and continuing to replace it, you avoid treating the problem, allowing it to worsen."
Additional glazing
"With triple glazing up to 40 per cent more thermally efficient than most uPVC double glazing, the extra layers can also help to reduce draughts, condensation and cold spots. With better insulation, you can moreover lower your energy bills and keep your home warmer in the colder months, meaning the extra cost is often worth it - especially as bills spiral," according to the pro.
Positive Input Ventilation (PIV) units
The double glazing expert says: "PIV units have several great benefits for your home, including improving the quality of air, eliminating humidity and condensation and reducing pollutants. PIV systems can also help to reduce any dust mite allergens and asthma symptoms.
"Another great bonus is that PIV units are incredibly cheap to run, costing from £1 to £2 a month after installation. For their low cost, their effective capabilities in eradicating both mould and condensation make them a popular choice."
What are the causes of damp and mould?
According to the NHS Choices website, mould and damp are caused by excess moisture. Moisture in buildings can be caused by leaking pipes, rising damp in basements or ground floors, or rain seeping in because of damage to the roof or around window frames. A newly-built home may be damp if the water used when building it is still drying out - for example, in the plaster on the walls. Excess moisture indoors can also be caused by condensation.
If you have mould or damp, it's important to find out why you have excess moisture in your home. When you know what's causing the damp, you can make sure your home is repaired or take steps to limit the moisture in the air. You may need to get a professional to remove mould for you - but, if it's only a small amount, you may be able to remove it yourself.
How does it affect your health?
The NHS says that if you have damp and mould, you're more likely to have or develop respiratory problems, respiratory infections, allergies or asthma. Damp and mould can also affect the immune system. Moulds produce allergens (substances that can cause an allergic reaction), irritants and, sometimes, toxic substances.
Inhaling or touching mould spores may cause an allergic reaction, such as sneezing, a runny nose, red eyes and skin rash. Moulds can also cause asthma attacks.
