Caravan Winterisation or Motorhome Winterisation

Caravan winterisation, and Motorhome winterisation is easy to do and below we have listed the steps to take. When we service your vehicle, we will winterise your van free of charge if you wish. If you would like us to do it for you on a separate occasion, we will be more than happy to do it for you, however there may be a charge


  • The Vehicles Water System – completely drain the hot and cold-water system in the van, you can do this by ensuring all the taps are open, these will by your boiler under a seat and then removing the drain plug, normally on the outside of the van (see owners handbook). This process can take up to an hour so please be patient.  A good time to drain the system is before you leave your last outing of the year, if you open the valves for the journey home it will make extra sure all water is drained. Once back ensure that the bung is replaced in the drain plugs but leave the taps open, to stop the build-up of pressure in the system.


  • Drain all water carriers completely and leave the plugs off to avoid unwanted smells.


  • The Toilet – Completely drain the water holding tank into the cassette and remove the cassette for draining and cleaning.  Once the cassette is fully cleaned out and rinsed use Thetford’s Maintenance Spray or similar to coat the cassette seal and blade. This will help avoid corrosion over the winter months (this is available from your local dealers). Using alternative chemicals may result in permanent damage to the seals. Leave the blade open to avoid sticking, this also helps prevent the cassette from being stolen.


  • Plug all water inlets and waste outlets to avoid smell and creepy crawlies coming in.


  • To take care of your upholstery, remove all cushions, pillows and bedding and if possible, store them in your home. If not remove the seats and back cushions and place them, end on end in the centre walkway of the caravan.


  • Open all internal doors and cupboards to allow the air to circulate.


  • Thoroughly clean the fridge/freezer with bicarb of soda or anti-bacterial liquid. Leave the door propped open to avoid pressure build up and a stagnant smell.


  • Ensure all windows and vents are locked shut and unobstructed and are secure from mice, spiders etc. Close all blinds/curtains for extra security.


  • Remove your leisure battery if you can and keep the charge topped up every 5-6 weeks, please note if you van has an alarm these normally are run off their own separate batteries, so removal of the leisure battery should not affect the security, (you will need to check out your own van to ensure this is the case)


  • If you can remove all gas cylinders do so and store in an adequately ventilated location.  If not ensure that all cylinders are fully turned off and the gas compartment is locked. Remember when storing Butane gas, it begins to freeze at temperatures below 4 degrees C. Propane does not.


  • Carry out periodic inspections of your van over winter to ensure that no damp is in the van and to ensure it is holding out against the frost.


  • Putting in several dehumidifiers in the motor home and caravan is always a good idea, you will be surprized how much moisture these collect. You don’t need the expensive ones, this is about being functional, and check them weekly of you can or if not put more in, 5/6 will be fine
