Key Takeaways: As October brings cooler outside temperatures and indoor moisture building up, condensation often becomes worse. Early action prevents mould, damage and discomfort.
- Outside temperatures drop, making indoor surfaces colder and increasing condensation risk.
- People spend more time indoors, producing more moisture from cooking, showers and drying clothes.
- Reduced natural ventilation in autumn traps this moisture, allowing droplets and mould to appear.
- Ignoring the early signs can lead to damage to finishes, furniture and health issues.
- Improving ventilation, maintaining temperature and addressing hidden damp issues help keep your home dry.
Most homes will have to deal with condensation at some point, but buildings are often designed to ensure this is a short-term problem. For example, you might notice condensation in your bathroom after a shower, but the extraction fan will be sufficient for removing the excess moisture from the room. The same goes for condensation appearing in your kitchen while you are cooking, but an open window or exhaust fan should be able to prevent this from lingering.
What we’re talking about in this blog post is the presence of a condensation problem, and this will often rear its head around this time of year. October is the prime time for condensation issues in homes due to a number of factors, including falling outside temperatures and a change in behaviour. In this guide, we’re exploring why condensation gets worse in London homes every October, and what you can do to fight back.
What causes condensation?
Condensation is caused by high humidity levels in your home. In an ideal situation, this moisture will be able to escape your home and it won’t settle on surfaces, but when it becomes trapped, it will be attracted to settle on the coldest surfaces in the room.
Some homes do not breathe as well as they could, which leads to a build up of condensation. You might notice it is worse after a shower or after you have been cooking a meal, but even simple things like sleeping will contribute to condensation. You exhale moisture on your breath when you breathe, and this can build up in your home if there isn’t sufficient ventilation.
A damp problem can also contribute to a condensation problem. This is because moisture is entering your home through the foundations, and this can contribute to high levels of humidity. No amount of ventilation will be able to address this, as there will also be more moisture.
Signs you might have a condensation problem
Condensation often rears its head and becomes more problematic around this time of year because a few contributing factors:
– The falling temperature means that your home might be cooler than usual.
– Your behaviour will change; you’re more likely to dry clothing indoors and have longer, hotter showers.
– If your condensation is linked to a damp problem, this can become more severe in autumn and winter as ground water starts to rise.
If you have a condensation problem in your home, it’s important that you’re able to spot the early signs so that you can take action. Common signs of a condensation issue include:
– Excess moisture on your windows, particularly in the morning
– Moisture on walls and doors
– Mildew and mould build up on walls, furniture and clothing
– A musty smell that won’t go away
– Soft wallpaper and peeling paintwork
Could your condensation problem be linked to a damp issue?
Condensation can be the result of how you are using your home and may be resolved by making more of an effort to ensure spaces are well ventilated. Dehumidifying units can also be highly effective in capturing excess moisture in your home.
If the issue is linked to an underlying damp problem, then these methods might prove to be ineffective. The reason is that your home is unable to handle excess moisture from your daily activities because it is already saturated with moisture from your foundations.
Autumn = High Risk Zone
When nights get colder and windows stay shut, warm moist indoor air meets cooler surfaces – the perfect recipe for condensation.
Maintain Air Flow & Surface Warmth
Keep vents open, use extraction, and ensure walls and windows stay warm so moisture can escape rather than settle.
So, if you’re dealing with a condensation issue that cannot be resolved, no matter what changes you make, it could be worth exploring if dampness is really to blame. Signs that you might have a rising damp problem would include:
– Water tidemarks on your walls
– Soft or rotting floorboards and skirting boards
– Peeling paint and flaky paintwork
– A damp or musty smell that won’t go away
– Emptying your dehumidifier units multiple times a day
– Mould build up on walls and behind furniture
If you’ve spotted any of these signs in your home alongside an excess of moisture buildup, this could be a sign that you have a combination of a damp problem and a condensation problem. Arrange a damp survey with our condensation experts in London to get to the bottom of the issues and take steps to prevent further damage to your home.
