Damp repairs
There’s always a sense of excitement getting away on a trip, and there’s a sense of relief when everything seems shipshape in the van.
But what if it’s not, and there’s that telltale musty smell that tells you all is not well?
Well, here’s the thing: leaks and damp can creep up on you, and even if all seems well, there may be something brewing. The best course of action is to ask us to run our damp meter over your van to check that all is well. It’s a simple and quick way to put your mind at rest. If there are issues that need attention, we’ll be happy to sort out any problems you may have.

How can I tell if my motorhome is damp?
You can often detect damp by musty smells, discolouration, soft wall panels, or condensation.
How can I tell if my motorhome is damp?
You can often detect damp by musty smells, discolouration, soft wall panels, or condensation.The best way I recommend to see if you have damp or water ingress is to book a Damp Report.
Damp in a motorhome can sneak in slowly, so it’s important to know the early warning signs. A musty or stale odour is usually the first giveaway, even if no visual damage is present yet. Other clues include discoloured wall coverings, bubbling wallpaper, black mould in corners, or soft spots when pressing gently on walls or ceilings. In colder months, you might also notice persistent condensation on windows or skylights.
These signs may point to moisture building up inside the structure – possibly from a leak or poor ventilation. However, not all damp is obvious to the naked eye, which is why many owners choose to have an annual damp check done professionally. Using moisture meters and pressure testing can detect problems long before visible damage occurs, potentially saving you thousands in future repairs.
What causes damp in motorhomes?
Damp is usually caused by leaks through seals, joints, or vents, and sometimes by internal condensation.
What causes damp in motorhomes?
Damp is usually caused by leaks through seals, joints, or vents, and sometimes by internal condensation.The number one cause of damp in motorhomes is water ingress, typically through failed seals around windows, roof lights, vents, or body joints. Over time, sealants degrade due to UV exposure, road vibration, and temperature changes. Even small cracks can let in moisture, especially during rainy seasons or when the motorhome is stored outside for long periods.
Another common culprit is internal condensation, especially in colder months when cooking, showering, or sleeping without adequate ventilation leads to moisture buildup. If warm air hits cold surfaces (like windows or walls), condensation forms and can slowly soak into timber or insulation. The key is prevention through regular checks and good airflow, especially in winter or when the vehicle is unused.
Is damp in a motorhome dangerous?
Yes, damp can lead to structural damage, mold growth, and costly repairs if left untreated.
Is damp in a motorhome dangerous?
Yes, damp can lead to structural damage, mold growth, and costly repairs if left untreated.Damp isn’t just a cosmetic issue – it can compromise the structural integrity of your motorhome. When moisture seeps into wooden frameworks, it can cause rot, weakening the walls, floors, or roof. Over time, this can affect the safety of the vehicle and make it much harder (or impossible) to repair without major work.
It can also cause health issues. Mould thrives in damp environments and can aggravate allergies or respiratory problems. Plus, the presence of damp significantly reduces the resale value of your vehicle. Many buyers will walk away from even minor signs of damp or expect a steep discount. Regular damp checks help catch these problems early and protect your investment.
How often should I check my motorhome for damp?
You should check at least once a year, or more often if it's stored outdoors or unused for long periods.
How often should I check my motorhome for damp?
You should check at least once a year, or more often if it's stored outdoors or unused for long periods.The recommended minimum is an annual damp check, typically as part of your routine habitation service. However, if your motorhome is stored outside, especially during the winter, it’s smart to check it every few months. Moisture can build up quickly in cold, damp conditions, especially if seals are starting to degrade or condensation is forming regularly.
During long periods of non-use, consider inspecting vulnerable areas like around windows, skylights, and seams, and running a dehumidifier or moisture trap inside. Early detection is key and even better, professional pressure testing can detect leaks long before they become visible. A little vigilance goes a long way in preventing major repairs.
Can I check for damp myself?
You can look for visible signs and use a damp meter, but professional checks are more accurate.

You can look for visible signs and use a damp meter, but professional checks are more accurate.DIY damp checks are a good starting point. Walk through your motorhome and look for peeling wallpaper, mould, dark staining, or spongy-feeling panels. You can also buy an inexpensive moisture meter online, which gives you a rough idea of moisture levels in various areas. It’s better than guessing but keep in mind, it’s only a surface-level check.
Professional inspections go deeper. Technicians use calibrated damp meters, pressure testing systems, and bubble solutions to find leaks that aren’t yet visible. These tools can detect early-stage water ingress that you’d likely miss on your own. That’s why annual checks from a trusted workshop (like us at Bristol Caravans!) are highly recommended.
How is a professional damp check done?
A professional damp check uses meters, air pressure, and bubble solution to find leaks and moisture inside the structure.
How is a professional damp check done?
A professional damp check uses meters, air pressure, and bubble solution to find leaks and moisture inside the structure.At Bristol Caravans, we use a multi-step approach. First, we inspect known weak points like windows, joints, vents, and roof lights for any visible signs of wear. Then we use a calibrated damp meter to measure internal moisture levels at key points. If readings are high or inconsistent, we go further.
We’ll seal the motorhome, gently pressurise the interior with an airline, and apply bubble solution around the outside. Any bubbling shows where air and water could be entering. This technique is precise, non-invasive, and helps us find even tiny leaks before they become major problems.
Can damp be repaired?
Yes, damp can be repaired, from simple sealant work to more involved panel or floor replacements.
Can damp be repaired?
Yes, damp can be repaired, from simple sealant work to more involved panel or floor replacements.Minor damp issues, like cracked sealant around a window or roof light, can often be repaired quickly and affordably. Resealing the affected area and drying out the interior may be all that’s needed. Moisture traps and dehumidifiers can also help reduce ongoing condensation issues.
However, if damp has been left untreated, it may have damaged internal woodwork or insulation. In those cases, we may need to remove and replace damaged panels, flooring, or even sections of framework. It sounds drastic, but restoring your motorhome properly is the only way to prevent future problems and protect resale value.
How can I prevent damp in my vehicle?
Regularly check seals, keep it well-ventilated, and book an annual damp inspection.

Regularly check seals, keep it well-ventilated, and book an annual damp inspection.Prevention starts with regular maintenance. Inspect and reseal joints, vents, windows, and roof lights every few years, especially before winter storage. Good ventilation is key too, leave skylights slightly ajar when safe, or use roof fans to prevent condensation buildup from cooking, showering, or sleeping.
Use moisture traps, especially during storage or in colder months. If your motorhome is unused for long periods, consider periodic airing out or using a dehumidifier. Most importantly, get a professional damp check at least once a year particularly before or after the winter season. It’s the best way to spot leaks early and avoid expensive surprises.
