Complete guide to caravan damp repair

If you're a caravan owner, you probably know that damp is one of the most common issues you'll face. Whether you own a touring caravan or a static one, dealing with damp is crucial for maintaining the integrity of your vehicle and ensuring it stays in good condition.

Caravan damp repair can seem daunting, but with the right knowledge and tools, you can tackle it yourself or at least have a clear idea of when to call in the professionals.

In this guide, we look at everything you need to know about caravan damp repair. We've got you covered, from removing moisture and understanding the costs involved to keeping your caravan damp-free through the winter.

Is it worth repairing a damp caravan?

This is one of the first questions many caravan owners ask when they discover damp in their caravan.

The short answer is, yes—it is usually worth repairing a damp caravan, especially if it's a more serious issue or if you intend to continue using your caravan for years to come. However, whether it's worth it depends on the extent of the damage and the age of your caravan.

Here's why it's worth doing the repairs:

• Structural integrity—damp can cause long-term damage to the frame and floor of your caravan if left untreated. Wood can rot, and metal parts can rust. This compromises the overall structure of your caravan, potentially leading to costly repairs later on.
• Health concerns—persistent damp can lead to mould and mildew, triggering allergies and respiratory problems. So, fixing the damp is a matter of maintaining your caravan's value and your health.
• Preserving value—if you ever decide to sell your caravan, a damp-free caravan will hold much more value than one with visible damage or ongoing issues.

When might it not be worth repairing?

If the damage is extensive, especially in older caravans, replacing rather than repairing may be more cost-effective. In cases where the damage has spread throughout the entire caravan, it could cost more in repairs than buying a new caravan. That said, a professional damp surveyor can help you assess this.

Can you fix damp in a caravan?

Yes, you can fix damp in your caravan. It's a manageable DIY project in many cases, provided you catch it early and know where to focus your efforts.

Small damp patches are often the result of poor sealing around windows, doors, or joints, and can usually be fixed with some basic tools and materials.

Essential steps for fixing damp in your caravan include:

• Identify the source of the damp—before you start repairing, it's important to figure out where the moisture is coming from. Look for leaks around the roof, windows, doors, or plumbing areas.
• Dry out the affected area—use a dehumidifier or moisture absorber to remove any excess moisture. Make sure the caravan is properly ventilated to speed up the drying process.
• Treat mould and mildew—if mould or mildew has developed, clean the affected areas with a mixture of water and vinegar or a specialised mould remover.
• Repair the leak—once the area is dry, you can repair any seals or damaged areas. This could be replacing seals on windows or doors, redoing the roof sealant, or replacing rotting wood.
• Repainting or resealing—after the repairs, make sure the area is repainted or resealed to prevent future damp issues.

If the damp is more severe, especially if it has affected the walls or floor of the caravan, you may need to call in a professional. A damp report or survey can help identify the full extent of the damage.

How to remove moisture from a caravan?

Removing moisture from your caravan is one of the most important steps in dealing with damp. There are several ways to do this effectively:

• Use a dehumidifier—this is one of the most effective ways to remove excess moisture from your caravan. Make sure to use a caravan-specific dehumidifier, as they are designed to work in smaller, enclosed spaces.
• Open the windows and ventilate—fresh air is one of the best ways to prevent moisture build-up. Open your windows regularly, especially when you're using your caravan or after heavy rain.
• Moisture absorbers—you can also use moisture-absorbing products like silica gel bags or dehumidifying crystals to help absorb moisture from the air. These are great for smaller areas and can help in between larger drying efforts.
• Check for plumbing leaks—sometimes, hidden leaks can cause dampness. Ensure all pipes are secure and there are no slow leaks adding to the moisture problem.

By tackling the moisture issue head-on, you'll prevent future mould and mildew problems that can cause even more damage to your caravan.

How much is a damp report for a caravan?

If you want a detailed evaluation of the damp in your caravan, it's worth investing in a professional damp report. These reports assess the extent of the damp, identify the source of the issue, and provide recommendations for repairs. Damp report costs can vary, but here's a general guide:

• Standard damp survey—expect to pay around £150 to £250 for a standard damp survey. This includes the inspection and a written report of the findings.
• More extensive reports—for more complex surveys or additional services, costs can rise to £300 or more.

While it may seem like an added expense, a damp report can save you from undertaking unnecessary or incorrect repairs, and it'll give you a clear idea of the work involved and the cost to fix the damp.

Where to check for damp in a caravan

When looking for damp, you should inspect several key areas regularly, especially if you suspect moisture in your caravan. Here's where to check:

• Around windows and doors—these are the most common places where water can leak in, especially if the seals have worn away. Check for cracks or gaps in the seals and look for damp patches on the surrounding walls.
• Roof—your caravan's roof is vulnerable to leaks, especially if you've had heavy rain or storms. Inspect the roof for any cracked or damaged sealant, as well as around roof vents.
• Floor—damp can often be found around the floor, especially in static caravans where the ground level is lower. Look for soft spots or areas of discolouration on the flooring.
• Plumbing—if water runs through your caravan's pipes, check for leaks or condensation around the pipes, particularly in areas where the plumbing meets walls or floors.
• Storage compartments—if your caravan has external storage compartments, these can be prone to damp. Open them up and check the area regularly.

How do you keep a caravan damp-free in winter?

In winter, damp problems can take hold in caravans, especially if you don't take the right precautions. Here's how to keep your caravan damp-free during the colder months:

• Insulate the caravan—insulation helps keep the cold and moisture out, preventing damp from forming. Insulating your caravan's roof, floor, and walls is a good investment to keep things dry.
• Drain down your caravan—if you're not using your static caravan over the winter, make sure to drain down the water system to prevent freezing pipes and damp problems. You can read more on how to drain down a static caravan here.
• Use a caravan cover—a high-quality cover will protect your caravan from the elements, particularly rain and snow. Make sure the cover is breathable to avoid trapping moisture underneath.
• Ventilation is key—even in winter, ventilation is crucial. Make sure your caravan has proper airflow to prevent condensation from building up. You can also use moisture-absorbing products in areas that are prone to damp.
• Store your caravan properly—if you're not using it during the winter months, store it in a dry, sheltered location. Keeping it out of the elements is one of the best ways to prevent damp.
