Caravan Winterization: Preparing your tourer for winter


If you intend on tucking your caravan up for the winter rather than braving a cold-weather tour, there are a few key steps you need to take in order to ensure it’ll be in a good condition when pulled out of hibernation in the spring.

touring caravan in the snow

Drain all water from the system

The number one priority is to ensure that all water is removed from the caravan’s fresh and waste water systems, as if left in the pipes this water could freeze and expand when the temperature drops below zero, causing the pipes to burst. Set all of the taps inside the caravan to the open position and open up any exterior water taps as well, to ensure all water has run out of the caravan.

Once this has been done you may also want to pour a little anti-freeze down the kitchen and bathroom plug holes, to ensure any residual water in the U-Bends does not freeze.

Also empty and clean out the cassette toilet with plenty of fresh water before completely draining the system. You may then want to apply some Maintenance Spray (such as the ones made by Thetford) to the cassette seal and blade to avoid corrosion or sticking over the winter months.

Fight the damp

Another issue over winter is the build up of condensation or damp inside the caravan, which in the short term can cause mould on soft furnishings or carpets but if left untreated can cause more serious problems of damp in the caravans woodwork and body shell – something you definitely want to avoid. Make sure that all soft furnishings are removed and stored inside your home for the winter, and that seat cushions are removed and propped up in such a way that air can circulate.

Cupboard doors and draws should be left slightly ajar so that fresh air can get in, and you should also completely empty and clean the fridge and freezer compartment using a little bicarbonate of soda and warm water, again propping the door open to allow air to circulate.

It’s also a good idea to place a few bowls of salt around the caravan as these will absorb the moisture in the air and help to stop damp building up on windows and surfaces over the winter.

Guard from the elements

Whether you are storing your caravan at home or on a storage site it is a good idea to take precautions to protect your caravan from high winds, or the worst of the elements. One way to protect your caravan at home might be to build a caravan porch. These can be built relatively cheaply and will protect your caravan from direct exposure to rain and snow over the winter months.

If you don’t want to splash out on the building of a caravan porch (or if you store your caravan away from home in an outdoor storage location) then a breathable caravan cover is another good way to protect your ‘van from the elements. It’s vitally important that you opt for a breathable, waterproof cover that lets fresh air in but keeps the wind, rain and snow out. Never use a plastic cover that doesn’t allow air to pass through as this will cause a build up of condensation on the inside of the cover (and in the van), undoing all your hardwork to avoid the dreaded damp!

Protect your wheels

Being stood in the same position all winter puts a lot of pressure on one area of a tyre, and can cause it to become cracked, warped or damaged. If your caravan is going to be left pretty much in one place for the duration of the winter, then you need to take some simple steps to ensure the tyres are in good working order come spring.

One simple way to spread the load across the entire tyre is to move the caravan periodically over the winter months, so that a different part of the tyre is in contact with the ground when moved back into its storage location.

It’s also a good idea to ensure tyres are inflated to the correct pressure, so check now and after every two months of storage.

Another option are “winter wheels” which completely replace your caravans existing wheels with square metal holders. These have the added benefit of making your caravan more secure as it cannot be towed away.

Please note: Providing the tourer’s normal wheels are stored securely away from the caravan then a Caravan Guard insurance customer would obviously not need to fit a wheelclamp when “Winter Wheels” are being used.

Clean and empty

If you aren’t going to be using your caravan over the winter then you’ll want to ensure that other little visitors such as mice aren’t making it their home for a few months either. Always remove all food stuffs from the caravan and clean out all the cupboards, ensuring no crumbs or dirt are left behind to attract vermin.

As well as giving the inside of the caravan a thorough clean, it’s also a good idea to clean the outside of the van and apply a protective wax or polish (AutoGlym and Fenwick’s offer a wide range of products suitable for caravans) to keep out the elements over the winter. This is particularly important if you aren’t using a caravan cover as it will give water and dirt nothing to hold on to, and make that first spring clean much easier next season.

Security and final checks

It’s important when your caravan is laid up for the winter that all windows and doors are locked and any security devices are engaged in order to comply with the terms set out on your caravan insurance policy. If you have a tracking device or alarm which uses battery power to operate then you may need to keep an external power source connected to avoid these devices running flat, or at least give your caravan leisure battery a regular charge. Of course some caravan tracking devices will warn you that they are due to run out of power.

If you don’t have such electronic security devices and all power is to be turned off in the caravan then it is a good idea to remove the caravan’s battery and keep it in your house on a trickle charge, to keep it in good condition over the winter.

Gas bottles should be disconnected and removed to avoid accidental leakage of gas through the system over winter, which is obviously a major fire risk. These can be stored safely in the garage until needed, but just be sure to double check that any taps are turned to the closed position whilst in storage.

    I would have thought that it was not a good idea to have a battery on charge in the house as a battery gives off a highly explosive gas when being charged it is recommended that when charging a battery it should be done in a well ventilated area.

  2. Ian Fleming says:

    Thanks for this advice as first season caravan owners it’s excellent and very easily followed

  3. Maz Tucker says:

    Thanks for the advice, we packed our caravan away at the end of October, there was a copy of things we didn’t do but most of the important ones we can happily say done. Thanks for the good advice.

  4. judith connors says:

    Good easy to understand advice. Thank you.

  5. mike sheldrick says:

    We have as first time caravaners adhered to the letter for winterising our caravan. We was wondering if to buy a caravan cover but some say no and some say yes what would you do ?
    Great advice to us newbies thanks.

  6. Neil says:

    Glad you’re finding the advice useful guys.

    With regards to caravan covers, we think they’re a great idea providing you go for a high quality breathable one. In fact, the caravan covered in snow in the photo belongs to a friend of Caravan Guard, and they have now purchased a breathable cover after the amount of snow we had last winter!

    It’s also a good idea to go for a cover which is specifically designed for your caravan as it will not only fit perfectly, but should also have a door zip, meaning you can still check inside the caravan sporadically through the winter.

    thanks again for everyone’s comments,

    Good helpful article on ‘winterizing’ the caravan – some things I hadn’t thought of.

  8. peter hicks says:

    I used a breathable cover for the first time last winter and was all good. The cover needed a few patches where it rubbed on projections ~ used the bag for patches ~ but the van was clean & tidy this spring.

  9. J Button says:

    Really helpful advice for us who are facing the first winter with our caravan. We had thought of most of it, but some really useful things we hadn’t.

    Just two questions – we have been advised to keep the mains lead plugged in all, the time to keep the battery charged. Do you agree with that?

    Secondly, a magazine article (sorry, no idea where or when) suggested putting a small electric heater on frost setting in the van, on the basis that the electicity it used would be far less than reparing any damage caused by ice or damp. What do you think?

    Many thanks, James

  10. David Hinchliffe says:

    One point not mentioned, to get all the water out of the van, close all taps, take the head off the shower and blow down the shower pipe, I got another litre of water out using this method, don’t forget to open tapes again afterwards, I also remove the filter as these can hold water, keep the filter to put in when you sterilise the pipes next spring, then replace it with a new one. Good article.

  11. David Hinchliffe says:

    In response to another questioner, we leave our van connected to the electric supply and have done so for the past 3 winters, with out problems, we also put in an electric greenhouse heater on frost setting when the weather gets very cold. hope this helps. David

  12. Neil says:

    Nice tip David!

    The “Floe” systems do a similar thing but using an electronic air pump, and will ensure that every last drop of water is flushed out.

    We’ve not tested the system ourself but the Caravan Magazine reviews have been nothing but positive: http://www.keepfloeing.com/

  13. David Hinchliffe says:

    The Flow system is very good, but costs about £40, mine is free. keep putting great articles in your news letter. Thanks David

  14. Dick Harrison says:

    We thought we had done everything but the WATER FILTER froze and split last winter. We now disconnect it so it has no residual water trapped in it. (Yes I know they recommend that it is replaced annually but they are not cheap and we haven’t used it much this year!)

  15. Neil says:

    James

    With regards to your two questions, we know that leaving a caravan plugged into the mains isn’t possible for some people, and perhaps more importantly that leaving a free standing electric heater on for so long could be a potential fire hazard, even if left on frost setting. However David’s advice above on using a greenhouse heater seems worth bearing in mind, as these devices are specifically designed to be left on permanently and have a very low heat output.

    That said, if you don’t have any electronic security that relies on it then probably best to just take the leisure battery, or if you do, then just plug your mains lead in overnight now and again to keep the battery topped up.

    Or you could just follow the tips above to avoid dampness or freezing, rather than relying on an electric heater.

    thanks for your comments,

  16. Graham Coulson says:

    If you take the battery out remember not to store it on a cold concrete floor as this could damage it. Thetford had a lot of problems last year with split toilet tanks , even if drained there was still some water left. They have a free upgrade drain pipe for some models , contact thetford and they will send you one free.

  17. Eileen Holt says:

    I keep my caravan at a friends house so I have a small solar panel in my front window which is connected to the battery to trickle charge it during the winter months.

  18. Brian Ellis says:

    Regarding battery charging, we leave our battery connected year round via an electronic timer which is set to come on 24hrs per week. Enough to keep the battery in top condition, rather than having to remember to plug.

  19. Mike and Bev Parrott says:

    Have been a caravaner for several years.Just bought a new swift 565,so many new additions compared to our old ‘van, so we are very grateful for all your advice and other comments,some of which we were aware of but equally some that we wer’nt aware.Thanks and keep on puting your ideas forward people, its nice to share so we can all be at the top of our game.

  20. A Reed says:

    We have a timer on our motorhome that comes on every night on economey 7 also we have a frost watch heater that comes on during the night and a dehumidifier running during the night – 7 years of this along with a cover has proved to be perfect

  21. peter scott says:

    no need to buy new water filter, just get a refill kit, either from caravan dealer or Fitapac

  22. ruth mcnulty says:

    I don’t know what or where the water filter is. Can someone explain what I should do to disconnect it please?

  23. Nigel Bancroft says:

    I have been considering putting a dehumidifier linked to a timer within the caravan during the winter period. Has anybody got any information about this method.

  24. Dick Harrison says:

    The filter is somewhere in the between the water connection and the taps. On our Bailey it is in the cupboard beside the Fridge under the sink but it may be on the other side nearer the water inlet.

  25. Graham Coulson says:

    A dehumidifier sounds great, but , watch out for how much they cost to run !!, they are not cheap. I have one and it works very well but i have stopped using it due to the cost.

  26. Dick Harrison says:

    I didn’t tell Ruth that the filter is not easy to disconnect. It might need two water-pump pliers to release the Speedfit connectors and also arms that bend always. I have looked at the Filtapac and it seems that using that as a replacement would make the operation much easier next winter!

  27. Colin Schofield says:

    Hi,
    Have just used the floe system on my coachman, dead easy! 20 mins, all done. £44 quid from makers direct, web address http://www.keepfloeing.com they also make a digital thermostat about £19, although I have not yet tried this. but intend to. I have no connection with them, but have found the MD Jason very friendly and helpful.

  28. Mervyn Stannard says:

    I would back up Colins comments on the floe system for draining have used on my Bailey Ranger this year and got over 1ltr out of the system

  29. Colin Schofield says:

    Revised address for keepfloeing.

  30. Colin P says:

    I jack-up the van with wheels off ground – will this avoid problems?
    Door opened as often as possible throughout winter – will this avoid damp?

  31. D Walker says:

    1st year having a caravan really good info. thanx :)

  32. jane s says:

    are the blinds up or down for winter ,i put 7 humifiers in my caravan when i went back in spring i had somemould in bathroom area any tips

  33. sid says:

    were is the drain plug for composs amega 482

  34. Raymond Carey says:

    When caravan stored away for winter make sure to take everything including curtains seats to protects from mould. With regards to the advice as in above comments, Do not puts bowls of salt during the winter as we previously done this for years on our older caravans, this can cause the screw area to rust, yes bad rust and mould on wood. Please make sure you use the proper item which can be bought at your local caravan accessory shop, we bought the kill rock moisture traps and was able to buy a refill bucket 2.5 kg which should be sufficient to dehumidify a closed room up to 40 cubic metres for up to 6 months, can be used for kitchens bathrooms and anywhere in the house, the refill bucket cost £13.00 and the units are about £5.00 each but you can use them year after year.

  35. Vic Holamn says:

    Can you seal off the floor vents during the winter to prevent damp air getting in? We store the caravan at home and open up to air quite regularly, but still see signs of slight mould forming on cushions which we stand sideways on the floor. Thanks

  36. Alan says:

    We have a central heating system with rads in our van,
    We have been told this doesn’t need draining down over winter
    Any advice please?
    Thanks guys

    • Hi Alan,

      Thanks for getting in touch. Can I ask which make and model you have? I’ll pass your query on to the relevant manufacturer. Guidance on this area often varies so it’s probably best seeking expert advice.

      Thanks

  37. Terence Boucher says:

    One point that I would mention. Is that prior to covering your van ensure you have it serviced especially for damp. Prior to going away to France in 2011 we had the van serviced as usual, on our return I cleaned the van and when dry put our cover back on. Due to constraints we have not used it for two years, I took it off recently cleaned the van (no pressure hose) and on checking inside found the bottom wall between the fridge and cooker was damp. I called our service engineer and on inspection he noticed that the outer fridge grill was showing possible mastic had degraded and that was where damp had come in. On taking the grill off it was noticed that in the top lh corner mastic was in fact missing! very possible that when being made a small portion had been missed. Consequently the centre piece of wood had become damp and a cost of £900 to renew the inside lhs completely. My advice therefore is to ensure you have the van serviced before putting the cover on and possibly have a check on your outer grills. The problem had possibly occurred in France where we had very heavy rainfall, who knows, although we did have regular servicing and damp meters applied. could have been a slow build up over the years.

  38. Terence Boucher says:

    One other point I would make, is to place your chassis on axle stands and cover the tyres the serves to give added security, also saves the tyres from standing on ground.

  39. Alan says:

    Hi lucie
    It’s a buccaneer cruiser
    2000 model, it has factory fitted central heating and aircon,
    This is a new purchase and has been very well looked after, and I would like to keep it this way, any help you may impart would be great fully received.

    • Hi Alan,

      I’ve had a look on the Elddis website for you but I can’t seem to find anything on the Cruiser. Like I say advice in this area differs depending on make and model so it’s probably best if you check your user manual or speak to your dealer. Alternatively, you could call Elddis on 0871 964 2113.

      Sorry I can’t be of more assistance.

      Thanks

      Lucie

    • Hi Alan,

      I passed your query on to caravan expert and journalist Doug King who tells me: “The advice not to drain down is correct. If you haven’t played around with the solution in the central heating system you don’t need to drain it as it is an antifreeze mixture.”

      I hope this helps!

      Thanks

    We are first time caravan owners and have left the warm air heating on low setting would you advise this it is plugged into the mains at home
