    hi guys,

    On holiday and woke up to soggy duvets today. Got a leak on the rear window. We can see where it is coming from.

    If I cannot get sikaflex to repair, any ideas on what I can use that I can buy in a b&e or similar? Is there a guide somewhere that someone can point me to please?

    Bit of a dampner!

    As a temporary measure, you could put a thick bead of sealant round the outside to deflect rain.

    Gaffer tape on the outside of the whole window frame, wait till home get it resealed then, when the window can be removed and check for where the water is getting in

    At the moment you only know where it is coming out (y)

    The Gaffer tape solution will be probably your best bet till you return home. You will be able to get it dry enough to stick. Sealant will struggle to adhere unless you use a specialist under water type.
    Good luck

    Try to see if it is coming in though between the glass and the frame or from around the frame itself. if its from the frame you will need to take the frame out and clean and reseal it, this is not as hard as you may think, as long as you take you're time and you have the tools, screwdriver with changeable head a sealant and sealant you will be fine.

    Thanks guys. With my leg being what it is I haven't looked at it yet. En route to Weston super mare where hopefully it will be drier and we can put on a temporary gaffer solution. Was thinking plumbers mate or similar on the inside?

    @Hydrocell from what my missus has told me, there is water pooling around the inside of frame (externally). Will investigate further when we stop.

    The problem won't be at the bottom it will be at the top or higher up that the bottom sill I would think. A mighty pain in the bum in this damp weather to get it dry enough to re-seal.

    Don't put anything on the inside. If your temp repair on the outside doesn't hold you're better off with the water coming into the van where you can see it and clean it up than it coming in and getting trapped between the inner and outer skins where it will end up soaking the body of the van doing damage you might not notice until it's too late.

    STIXALL is pretty good you can use it even when it's wet and it will seal it.

    When we had this problem with a newish caravan we had to replace the rubber all around window, a Dealer not the one we bought the van from contacted the maker and managed to get us the rubber free of charge , hubby and I managed the job on our own.

    Had this problem on both side windows in Greece and stopped for the remaining 4 weeks of the trip using gaffer tape as mentioned. Windows renewed by Autotrail on return under warranty though van was over a year old. As said, DO NOT seal the inside, but do seal the complete window surround till you return.
    Good luck.

    Hi guys - back from hols. The leak was more or less sorted by putting gaffa on the outside of the window (albeit, there was one or two drips coming through, but 95% less water at least). So, now I'm back. How do I go about fixing the window..?

    I have a friend who does double glazing who is happy to help me, if I can tell him what needs to be done. I'm assuming, remove the window and sikaflex the seal?

    So, how do I remove the window, inspect and seal? And are there other things I should be considering (i.e. whether I need a new rubber seal?) The van is 6 years old.

    The inner & outer parts of the window squeeze the van wall between them. Undo all the inner screws (they may be hidden under trim caps) whilst your helper outside the van leans gently on the window to stop it falling out. Remove inner frame then from the outside remove the window. If it is stuck to the van wall it may need gentle pressure from the inside or the use of a broad plastic kitchen spatula to free it. Clean off old sealant - white spirit will clean off remnants - then allow window cutout to dry if still wet. Use the type of mastic linked below this message. Do not use Sikaflex (the variety most people mean is a polyurethane adhesive which will make an excellent seal but will also prevent future removal of the window). No sealant should be used inside the van.

    ............... which is also available in various widths from most caravan / MH accessory shops.

    Thanks for this - appreciated.

    A couple of questions:

    Am I right in thinking that the mastic will be placed over the rubber seal and then pushed into place?

    The width of the tape, can I tell what width is required, or is it a case of removing the window, measuring the seal and then going with that?

    they should be fitted on non setting mastic ribbon tape dont use silicon of any sort as they are very acidic and can cause corrosion problems

    if you use 20mm mastic and its too wide, you can just trim off the excess with an old credit card etc. it always oozes a little anyway just dont be tempted to overtighted the screws and force all the mastic out

    If the gaffer tape virtuall cured it suggest the water is coming between the window plastic and the seal and not between the window frame and the van, it will be worth checking that the drainage channels are clear.

    And gaffer tape can be an absolute sod to get off after some time so don't leave it any longer than needed.
