Caravan & Motorhome Damp Repair Specialists in North Wales

Evans Caravan and Camping provides professional caravan and motorhome damp repairs in North Wales, including moisture testing, leak detection, resealing and repairs from our workshop in Chwilog near Pwllheli.

Soft walls, stained panels, musty smells and spongy floors can indicate water ingress. Finding the source early may prevent the affected area from becoming more extensive and expensive to repair.

  • Professional damp and moisture testing
  • Water-ingress and leak investigation
  • Window, roof and joint resealing
  • Wall, panel and floor repairs

Send us photographs of the affected area, the caravan or motorhome details and a description of the symptoms. We can then advise whether a workshop inspection or damp test is required.

Warning signs to look for

Common Signs of Damp and Water Ingress

Damp is not always immediately visible. Changes to the walls, floors, seals or smell inside the vehicle can indicate a developing problem.

1

Soft or Spongy Walls

Interior wallboards may feel soft, uneven or less solid when pressed.

2

Stains or Discolouration

Dark marks, water stains or changes in the wall finish may indicate moisture behind the panel.

3

Musty Smells

A persistent damp or musty smell can indicate hidden moisture or affected internal materials.

4

Cracked or Failed Sealant

Sealant around windows, roof fittings, rails or corner joints may shrink, crack or separate over time.

5

Springy or Uneven Floors

Movement or softness in the floor can be associated with water damage or delamination.

6

Persistent Condensation

Ongoing moisture or condensation that does not clear may need further investigation.

Do not ignore a suspected leak. Water ingress can continue behind wallboards and fittings even when the visible area appears relatively small. Arrange an inspection before the affected section becomes more extensive.
Find the source before repairing

Damp Testing and Leak Detection

Moisture testing helps identify affected areas and gives the technician a clearer understanding of how far the water ingress may have travelled.

The visible stain or soft section is not always where the leak began. Water can enter around a window, roof fitting, rail or joint and move behind internal panels.

  • Moisture readings in relevant areas
  • Inspection of seals and external joints
  • Checks around windows and roof fittings
  • Wall-panel and floor assessment
  • Identification of likely ingress points
  • Advice on suitable repair options

Clear advice before work begins

Once the affected area and likely source have been assessed, we can discuss the work required and provide further information about the repair.

The extent of the repair cannot always be confirmed until damaged internal materials are opened or removed, particularly where water has travelled behind panels.
