How to Winterise Your Static Caravan. The Ultimate Guide for a Cosy & Carefree Winter

Why Winterising Matters

As the crisp air settles in and temperatures start to dip, it’s important to prepare your static caravan for winter. Whether you’re closing up for the season or planning the occasional winter escape, winterising helps protect your caravan from damage caused by freezing temperatures, damp, and neglect.

Neglecting these steps could lead to burst pipes, mould, or costly repairs — all of which can easily be avoided with a bit of preparation.

Step 1: Drain Down Your Water System

Water left in pipes can freeze and expand, leading to leaks or bursts. To prevent this:

  1. Turn off the main water supply.
  2. Open all taps (hot and cold) to let water drain out.
  3. Flush the toilet to empty the cistern.
  4. If possible, use compressed air to blow out any remaining water from the system.
  5. Pour a little non-toxic antifreeze into plug holes, traps, and the toilet bowl.

💡 Tip: Some holiday parks offer professional drain-down services — a good option if you’re unsure.

Step 2: Deep Clean Before You Leave

A thorough clean now means fewer surprises in spring. Empty cupboards and the fridge, wipe down all surfaces, vacuum floors, and remove any food to discourage pests.

Don’t forget to clean curtains and upholstery — mildew loves fabric left in damp conditions.

Step 3: Ventilation is Key

Condensation can cause mould, so balance security with airflow:

  • Leave internal doors and cupboards open for air circulation.
  • Fit moisture traps or dehumidifier crystals.
  • Keep vents clear — don’t block them for “warmth,” as this can make damp worse.

Step 4: Protect Furniture & Soft Furnishings

If you won’t be using your caravan for a few months:

  • Store bedding and cushions in airtight containers.
  • Lift seating cushions away from walls to allow airflow.
  • Cover furniture with breathable sheets to keep dust off.

Step 5: Disconnect Gas & Electricity

Turn off all appliances and unplug them. If you’re using bottled gas, disconnect and store bottles securely outside. Remove any batteries from alarms, clocks, or remotes to avoid corrosion.

Step 6: Check Exterior & Gutters

Inspect the exterior for damage and make sure seals around windows and doors are intact. Clear gutters and downpipes to prevent blockages and freezing water buildup.

If your caravan is near trees, consider a breathable cover to keep debris off the roof.

Step 7: Do a Final Security Check

Lock all doors and windows, draw curtains to deter prying eyes, and make sure your security system (if you have one) is active. Motion lights or timers can also help deter unwanted visitors.

Bonus: Winter Visits

If your park stays open year-round, winter stays can be magical — think frosty mornings, quiet walks, and cosy evenings by the heater. Just make sure you keep a small toolkit and antifreeze handy in case of cold snaps.

In Summary

Winterising your static caravan might take a day, but it’ll save you time, money, and stress in spring. Drain, clean, ventilate, and secure — and you’ll return to a caravan that’s fresh, dry, and ready for another season of memories.
