How caravan skirting is made and fitted
The planks
Skirting uses the same uPVC profiles as decking fascias: tongue-and-groove planks about 150 mm wide in white, cream, oak, grey or green, fixed to a light frame that stands on the ground and clips to the chassis rail. Taller planks or a double row are used on lodges and park homes that sit higher. The plastic does not rot where it touches wet ground, which is why timber skirting has mostly disappeared from parks.
Vents and hatches
The space under a caravan needs to breathe, or condensation forms on the underside of the floor. Installers fit vents at intervals, usually two or more per long side, and a hatch near the stopcock and the waste connection. Park rules often say the void under the van must not be used for storage, so the hatch is for access only.
Fitting with decking
Where a deck meets the van, the skirting runs under the deck edge so the two finish flush. If you are having decking fitted, order the skirting with it: the installer is already on site with the materials and the colour will match exactly.
Ground and frost
Skirting sits on the ground, so it should be bottom-edged with a flexible trim or set just clear of gravel to allow for frost heave and settlement. On a sloping pitch the planks are stepped, not cut on a slant.
