Before you go into the detail of how to stop condensation in a caravan, you must first know what causes condensation in a caravan.

What Causes Condensation In A Caravan?

What Causes Condensation In A Caravan?

Here are some common causes of condensation in a caravan:

Poor Caravan Ventilation

The primary cause of condensation in a caravan is poor ventilation. When you keep the windows or door closed while performing daily chores, a temperature difference is created between the inside and outside of the caravan. This temperature difference causes condensation, especially during winters.

Cooking In Your Caravan

When you’re cooking in the caravan with the windows and door closed, moisture and water vapours start to accumulate in the caravan. Due to this, again, a temperature difference is created, which leads to condensation.

Weather Affects Your Caravan

During the cold weather, you keep the windows and door closed to keep your caravan warm. Moreover, you also use heaters to warm up the air inside your caravan. In such situations, condensation forms at the cold surfaces such as roof and door as they become cold due to weather.

Storing Wet Clothes In A Caravan

Wet items, such as towels, coats, or clothes can cause condensation. These wet items also create a temperature difference, a triggering factor for condensation. If you’ve wet items in your bathroom, the chances of condensation increase significantly.

Human Impact

You’re also contributing to creating condensation in your caravan by breathing and sweating. It’s believed that an adult can produce about 1 litre of water only by breathing in 12 hours, and this water creates moisture that causes condensation.

Is Condensation The Same As Damp?

How To Stop Condensation In A Caravan

By knowing the causes of the condensation, you must be wondering that it’s inevitable. It’s true, condensation can’t be avoided completely, but it can be minimized or stopped to some extent by following the tips below:

Improve Your Caravan Ventilation

Increasing the airflow in the caravan is the easiest way to get rid of condensation. Your caravan should ideally have at least two openings for ventilation. Moreover, you can also use a DC or battery-operated fan for keeping in the window. It will increase the airflow in the caravan, which stops condensation by reducing moisture.

Don’t Do Laundry In Your Caravan

Wet clothes can also increase moisture in the caravan; therefore, you should avoid drying laundry in the caravan where possible. Instead, you can use the caravan site facilities or nearest launderette for this purpose.

Wood Stoves For Caravans

Wood stoves work by using the moisture of the air. When the moisture is reduced, condensation will not form. Especially in cold weather, wood stoves are excellent to stop condensation in the caravan.

Ventilated Heaters For Your Caravan

In winters, you need heaters to keep your caravan warm. But heaters produce a water vapour that can cause condensation. Unlike other heaters, externally ventilated air heaters produce negligible water vapours. Thus, they are a great choice to stop condensation.

Dry Your Caravan Thoroughly

If you’re not going to live in the caravan for a while and you’re either putting it into storage or simply leaving it on your permanent caravan site, you really should dry all the places in your caravan where damp can form. These include walls, cupboards, furniture, etc. You can also put damp absorption crystals in your caravan, and these crystals absorb moisture and protect your caravan from condensation and dampness. They’ll also help prevent rust and squeaking door hinges when you return.

Invest In A Caravan Dehumidifier

Based on your caravan’s location, a dehumidifier can be the best way to stop condensation in the caravan. The recent models have a humidistat that can detect relative humidity to maintain safe humidity levels.

It’s an excellent way to stop condensation, freshen the air and reduce moisture. It can help reduce moisture on rainy days and winters when moisture can develop even from damp clothes.

Is Condensation The Same As Damp?

No, condensation isn’t the same as damp. But it can change to damp if you ignore it for long. Dampness is a more severe problem than condensation, and you can see visible signs of damp. These include visible spots on your caravan walls and an unpleasant musty odour.

What Are The Consequences Of Condensation In A Caravan?

If the moisture levels are high in your caravan, it can promote mold build-up that’s extremely dangerous to your health. If you’re exposed to mold, you’re at the risk of developing skin, eye, and throat irritation.

Moreover, the moisture can cause corrosion. Even a tiny amount of moisture will lead to corrosion; however, the speed of the process depends upon the amount of condensation.

What is good to get rid of moisture in a caravan?

If you want to get rid of moisture in a caravan, you should improve the ventilation, avoid drying laundry inside, and use a dehumidifier or a low-wattage heater. You can also use clove oil solution or dehumidifying crystals to reduce moisture. Keep your caravan clean and dry at all times and open the windows whenever you can.

How to stop condensation in a motorhome

There are several ways to stop condensation in a motorhome. One way is to use a dehumidifier or moisture removing products like damp rid or Eva-dry. Another way is to keep the motorhome warm and use double pane windows or lids while cooking. Opening a window or ceiling vent can help some of the humidity escape.

Running a fan can help evaporate condensation and evenly distribute the air temperature throughout the motorhome. Running a dehumidifier as well as a ceramic electric space heater are the two most common ways to prevent condensation inside a motorhome.

What Are The Consequences Of Condensation In A Caravan?


Condensation is a common problem in caravans and even at homes too. You can’t avoid it, as many things can increase moisture in your caravan that causes condensation. These include poor ventilation, weather conditions, cooking, wet, items, and even you.
