    I need some advice from anyone who has first hand experience of damp problems and fixing them. I've just had a habitation check done on a prospective purchase and it was found that a vent (blanked off from a previous heater installation) had been leaking. The damp meter identified a small area about 12 inches wide by 4 to 5 inches high at the base of the wall around this vent (circular blanking plate - see picture). The vent was removed and resealed. The examiner said that it would dry out gradually and not to worry about it. This was at a local motorhome dealer. I could feel a small area, maybe 6 inches by 1/2 and inch which was a little soft right at the base of the wall directly under the vent. His explaination seemed plausible given the evidence. The rest of the van was ok. Would this be a deal breaker? Do things dry out as I have been told (given that there is no more water ingress). This is a private purchase and it is a good clean van, the best I have seen so far. It is a 2006 Autocruise Starfire. No doubt people have damp problems and they get fixed. But just how concerned should I be?

    If you are happy with the dealers explanation, and as he say`s nothing much....

    Could be a good bargaining tool to get the price down a bit..:Wink:

    And do a reseal in the area when you get it...:Cool:

    Looks to be in a place that will not notice.. :thumb:

    It depends how soft (= how badly damaged) I suppose. We had damp identified in our main locker (rear offside corner) last August which required a (larger) piece cutting out, replacing and resealing. It cost a bit but not excessive considering the value of the van.

    We then had a few isolated spots of high readings in parts of the walls identified during the habitation service in January. That turned out to be minor ingress due to sealant starting to crack/shrink. We've had it re-sealed and it should dry OK.

    As Mo says, try to get the cost of any repair knocked off if the rest of the van is OK.

    Old-mo, what do you mean by a reseal? The offending vent was resealed today when it was identified. Or is this some other sort of seal that you are referring to.

    I'm more than capable of doing repairs. The trick is knowing just what to do or even if repairs are necessary.

    Sorry... :Sad:.. didn`t realise it was done today...

    Some one will be along, as I cannot remember the stuff.... But there is some thing you can inject into damp places and after it has dried and cured it sets rock hard...:thumb:

    But if you are happy and can get some sort of warranty on the area and repairs,,,, I would still try to get a bit more off the price.... wont hurt to ask... :thumb:

    Just re-read and see it`s a private sale, so doubt once you have bought there will be any redress..

    You have shown the blanking plate on the inside. The important seal is the outside what does that look like and has it been properly sealed.

    I would also have left the internal blanking off to allow moisture to escape and aid the drying process.

    Hi the stuff Mo is on about is Wet rot wood hardener (I think):Wink:If it's sealed on the out side then take the cover off on the inside -treat and leave until it's dried out :thumb:
    from your pic it does not look serious but deffo use it to drive the price down :thumb: most people don't understand damp :BigGrin: but almost everyone understands damp kills the value on a van -that's why people try to hide it :Wink:-9 OUT OF 10 will walk at the slightest damp -tell them you are prepared to take the risk provided the price drops accordingly :BigGrin:

    That's exactly my thoughts too Paul, when I saw the photo. :Sad:

    Regards,

    The vent on the outside had been completely sealed off and the vent body to wall seal had hardened and let the water in. That is the bit that has been resealed. I would probably remove it and replace. The inside plate is not the functioning seal. Thats just to cover the hole.

    I suppose the first thing that comes to mind is - if you don't trust what the chap who has done the test is telling you then why did you go there? As he doesn't appear to be gaining any benefit from this, in fact quite the opposite as he's not trying to get you to pay him to fix it, then my feeling would be to trust what you have been told and from what you have said I would have come to the same conclusion as the chap too.

    So assuming you go ahead and buy it, with a suitable discount, remove and refit the external cover with a suitable sealant (Sikaflex will do one). Also let it dry out properly and use the stuff that Terry has suggested and don't worry about it.

    If the rest of the van is good (have you had a mechanical check done?) and the price is good it would seem to be okay to proceed. Without knowing much more about the vehicle/age/condition though it's difficult for us to really advise further.

    Done a fair bit with damp vans in the past.
    As it is in a locker, I would remove an oblong section of the wallboard to check the extent of the damp & let it dry out properly, It will take forever to dry with the plasticised wallboard in place. Then treat the wood & fit a new piece of wallboard.

    Morning, after reading Pauls comment about shit job on blanking plate I had a good look again :thumb: Yep it is a shit BP BUT I can also see it's in a locker (underbed?) It is also under the leccy plug (entering the van) Why anyone would want to put a vent there beats me.
    I would still go ahead and follow my earlier advice etc, especially about knocking the price down :Wink: but do follow your instincts and don't get carried away with your wants it :Smile:Further investigation on your part is required,do you trust your local dealer who did the test -what has he to gain by telling you it's nothing to worry about ?He probably gave you his opinion after seeing both sides of the van,plus the van has nothing to do with him so what does he gain? How close to you is the van ? is it close enough to go back and take more pics etc,and have a very good poke around that hole?
    If it was me I would ask if I could TAKE THE PLATE OFF TO HAVE A GOOD LOOK -that alone will bring the seller down to earth so offer a couple of K less :Wink: and see there reaction :Smile:(poss more off:Wink:)Damp can be very expensive to have done for you, but if you are any good at DIY it can also be a easy fix.Just be cautious and good luck :Smile:

    I'm curious... why does it have what looks like a submersible pump inlet ( right of EHU socket) feeding a wall mounted shure-flo pump .. ?

    Or am I mistaken ..

    Also looks like laminated flooring has been laid.. and not fitted very well.. (gap around wheel arch) .. or are they all like that ?

    The more I look at this picture and the read the OP text the more I dislike this van

    * odd place to fit a heater.. and why would it need one ? This van would come with both water and space heater..
    * strange water pump set up.. this submersible pump inlet is not shown in other pictures of this van on Google. .. and it has an on board fresh water tank.. why ?
    * badly fitted flooring..
    * the wall patch is very poor.. (that's being kind)

    and we haven't seen a picture of the outside..

    I'd want these questions answered before even starting to bargain..

    I think the photo in the OP is on its side. What shows as the RHS is the bottom as there is a yellow manual dump valve there.

    Don't think so, looks correct way up to me to me Graham .. that's the wheel arch on the right, under the shureflo..

    lots of strange things in that photo..

    *dump valve on wall
    * dodgy patch
    * submersible pump inlet feeding shureflo
    * heater (allegedly) fitted under EHU socket..

    without a physical inspection it's all conjecture based on one photo (which may be upside down :Laughing:)
