Introduction

Every motorhome owner dreads the word damp. But most causes are predictable — and preventable if you know where to look.

The Top 5 Causes

1. Window and Door Seals
   Rubber seals shrink and crack over time. Regular resealing is a must.

2. Roof Joints
   Movement while driving stresses joints. Without resealing, water finds a way in.

3. External Accessories
   Bike racks, awnings, and ladders create extra penetration points. These need annual checks.

4. Ageing Mastic
   The flexible sealant hardens with age, leaving cracks.

5. Neglected Repairs
   Small knocks or scratches can expose raw material underneath — easy entry points for moisture.

Prevention Tips

• Have seals inspected every 12 months.

• Store your van under cover if possible.

• After heavy rain, check for internal condensation or leaks.

• Book a professional damp check every year.

Our Advice

Don’t give damp a chance. Regular maintenance costs little compared to major structural repairs.
