Introduction

Damp is the silent enemy of every motorhome and caravan owner. You may not see it coming, but once it sets in, the repair bill can run into the thousands. A simple yearly check could be the difference between enjoying your pride and joy or facing a complete rebuild.

What Causes Damp in Motorhomes?

• Leaking seals around windows, doors, and skylights.

• Roof joints where panels and trims meet.

• External fittings such as ladders, bike racks, or awnings where screws pierce the shell.

• Ageing mastic that loses flexibility over time.

Moisture sneaks in slowly. Left untreated, it weakens walls, causes soft floors, and creates a breeding ground for mould.

The Cost of Ignoring Damp

• Small leak left untreated: £200–£500 repair.

• Damp spreading into the wall structure: £1,500–£3,000.

• Full panel or floor replacement: £5,000+.

That’s not scare tactics — it’s what we see in our workshop every year.

Why a Professional Damp Check Matters

• Full perimeter inspection of walls, floors, and roof.

• Moisture readings at all known problem points.

• Sealant and joint condition report.

• Advice on prevention before problems spread.
