Maintaining the comfort and cleanliness of your mobile home is essential to ensuring enjoyable and worry-free travels. One issue that can quickly compromise the interior environment of your caravan is the growth of mould and mildew. This can be visible on any part of your caravan, but is particularly prevalent on the window seals. These fungi not only detract from the appearance of your caravan but can also lead to unpleasant odours, health concerns and even damage to the seals themselves.
Understanding how mould and mildew develop and taking steps to prevent their growth is an important lesson for any caravan owner. This article from Caravan Seals explores practical strategies to keep your window seals mould-free. We look at our both personal experiences and tried-and-true methods to help you maintain a clean and healthy living space in your caravan.
What Causes Mould and Mildew?
Before looking at how to prevent mould and mildew, it's important to understand why it develops on caravan window seals in the first place. Mould and mildew are types of fungi that thrive in environments where moisture, warmth and poor ventilation are present. In a caravan, the combination of these factors can often come together, especially around window seals. This can create the perfect conditions for these unwelcome guests to take hold.
Window seals can trap moisture over time. This can occur for several reasons. First, the seals are constantly exposed to the elements, meaning they endure rain, condensation and humidity. Even small amounts of moisture can accumulate in the seals, especially if the caravan is not regularly ventilated or if it is stored in a damp location.
Temperature fluctuations can exacerbate the problem. For example, in cooler climates, the warm air inside the caravan can meet the cold surface of the windows and lead to condensation. If the seals are not properly maintained or if they begin to wear down, this moisture can become trapped and provide an ideal breeding ground for mould and mildew.
Poor ventilation further compounds the issue. Caravans, by their nature, are compact spaces where air circulation is often limited. When windows are kept closed for long periods, such as during storage or when the caravan is not in use, the lack of airflow can cause the interior to become humid. This stagnant moist air settles around the windows and seals encouraging the growth of mould and mildew.
Our team have all experienced first-hand where persistent rain and chilly temperatures led to condensation inside our caravans. The window seals, often already a few years old, began to show signs of mould growth, particularly in areas where water had collected. I’m sure this is a common experience for us all of how quickly these conditions can lead to problems if not managed properly.
Regular Cleaning, Inspection and Maintenance
One of the most effective ways to prevent mould and mildew is through regular cleaning. Using a mild detergent and warm water, gently clean the window seals to remove any dirt or grime that can trap moisture. It's advisable to do this at least once a month, or more frequently if you've been travelling in wet conditions.
We always recommend paying special attention to the grooves and crevices of the seals. These areas are prime spots that are often missed with a quick wipe. After cleaning ensure the seals are thoroughly dried with a soft cloth to eliminate any lingering moisture.
Periodic inspection of your window seals can help you catch early signs of mould or mildew before they become more significant issues. Look for discolouration, a musty smell or any soft spots on the seals that might indicate the beginning of fungal growth.
Ensuring Proper Ventilation and Using Dehumidifiers
Good ventilation is required in preventing the build-up of moisture inside your caravan. When cooking, showering or even just during humid weather, make sure to open windows or use ventilation fans that allow the moist air to escape. This reduces the amount of trapped damp air and the chances of condensation forming on windows and seals.
We always make it a habit of opening the windows slightly during the day, even in cooler weather, to promote airflow. We find that this simple practice allows the damp air to escape and significantly reduces condensation and, subsequently, the occurrence of mould.
For those who often find themselves in humid environments or during the winter months when ventilation is less feasible, using a dehumidifier can also be a game-changer. These devices help remove excess moisture from the air and create a less hospitable environment for mould and mildew. We use a compact portable dehumidifier from Screwfix that runs quietly in the background. Especially during trips to coastal areas where humidity is higher, it's been instrumental in keeping the interior dry and mould-free.
Proper Storage
How you store your caravan when it's not in use also plays a role in preventing mould and mildew. If possible, store your caravan in a covered dry location. If indoor storage isn't an option, investing in a quality caravan cover that allows for breathability can protect against moisture accumulation.
After a particularly damp autumn season, we moved our caravan under a carport rather than leaving it exposed. This change significantly reduced the moisture levels inside, and I noticed far fewer issues with mould when I took it out again in the spring.
