In this article, we will answer the following question: How do you fix damp in a caravan? We will discuss the prevention of mould and damp in a motor house and the quick solutions to fix these issues.
How do you fix damp in a caravan?
Fixing damp in a caravan takes time, and sometimes lots of money (that is if you want to replace the affected areas). The simplest solution is to wait for it to dry out. There are a few tricks that can quicken the process, but it is also essential to understand where all of this humidity came from and prevent it.
Thus, here are our quick solutions and preventions methods to fix damp in a caravan:
- Use a garage dehumidifier for winter storage – When the temperatures are cool, particularly between October and March, the humidity level increases considerably inside the premises. Mould, musty smell and rust are the consequences.
- Invest in a good hygrometer – Hygrometers help control humidity levels and take the necessary measures against mould in good time. It helps reduce the damp in the caravan by regularly ventilating the cabin, including creating a draft for five minutes.
- If the caravan is contaminated with mould – Clean the mould-prone surfaces with an appropriate disinfectant that kills and removes mould spores. Contaminated textiles should either be discarded or treated with disinfectant and then washed at a minimum of 60 ° C,.
The problem of too high a humidity level in a caravan appears especially on winter days, after cooking or showering. If the humidity level regularly exceeds 70%, it can cause rust, mould, musty odour and rot. To remedy this, dehumidification must be carried regularly.
How to reduce humidity in a motorhome?
With the onset of fall and the colder temperatures, you will no doubt have seen condensation forming on your windows. As the air outside is colder than the air inside your motorhome, the water vapour contained in the ambient air liquefies in contact with the cold surface of the windows.
The humidity thus generated is a plague on your vehicle. It can cause mould, damage woodwork which will rot over time or corrode metal parts.
It is therefore very important to protect your motorhome against humidity and there are simple and inexpensive solutions.
Start by measuring the humidity in your caravan. Humidity is measured using a hygrometer. It indicates the level of humidity present in the air. To measure the humidity level, you can use a hygrometer or a weather station in which it is generally integrated.
The ideal humidity level recommended normally is around 40-50% relative humidity. But in winter, to avoid condensation, you have to go below 40%. It is advisable to regularly measure the humidity level inside your motorhome in order to anticipate possible damage and prevent the appearance of mould.

10 tips to fight against humidity inside a motorhome
- Thoroughly inspect the motorhome and plug the “air holes”
Walk around the vehicle and locate any small holes or visible cracks in order to fill them up. Go up on the roof and check the joints of the skylights. In general, go around the windows and do not hesitate to run your finger along the joints to feel the air infiltration.
- Improve insulation and glazing
Manufacturers pay particular attention to insulation on new models of motorhomes because they know that motorhomes now travel in all seasons. So there are a lot fewer problems with recent vehicles.
On the other hand, on older models, do not hesitate to have a repairer diagnosed and consider improvement work.
- Install a dehumidifier in your motorhome
Arguably the simplest solution, purchasing a dehumidifier can be a very worthwhile investment by extending the life of your vehicle and your comfort.
The principle is simple: the air is drawn into the device and gets rid of the water vapour by meeting a cold surface on which it will liquefy. The water is thus collected in a tank which must be emptied regularly.
Electric dehumidifiers take up a bit of space but are very efficient. For a more discreet and especially less bulky model, you can opt for a humidity absorber so the action is more passive but which offers the advantage of not requiring a power supply.
- Slightly heat the vehicle
Heating naturally dries the air. There is no need to dramatically increase the room temperature. A few degrees are usually sufficient to clear the atmosphere.
- Activate ventilation in the wet rooms
Make sure that the ventilation works perfectly in the kitchen, bathroom and toilet. Remember to regularly clean the air vents, which can become blocked over time.
- Aerate regularly
Leave a window ajar to facilitate air circulation.
- Avoid creating additional water vapour
It is often easier to avoid releasing water vapour than to get rid of it then. Remember to put a lid on your pots when you boil water. Avoid drying your laundry inside the vehicle. Take your showers outside when possible. Cook as much as possible outdoors
- Leave cupboards open
A little trick is to leave all cupboard doors open to equalize the temperature throughout. It is essential to promote the circulation of air in all nooks and crannies. Plus, if an infiltration happens in a closet, it will be easier to spot and prevent you from having unexpected surprises down the road.
- Make sure your mattress is protected
Using a thermometer, measure the temperature under the bed. If it is 5 to 10 ° lower than the room temperature, it will be necessary to reinforce the insulation under the bed. Avoid contact with the mattress with a cold surface.
If your motorhome is housed in a shed, visit it to check that it is properly insulated and that there are no visible traces of mould. If you protect your vehicle with a protective cover, be sure to choose a breathable motorhome cover. Microporous, they allow air to circulate and remove moisture.
Regularly measure the humidity level inside the vehicle and record it in order to follow its evolution. If you detect a significant increase in humidity, it may indicate a leak in the roof or walls. In this case, conduct a thorough inspection.
