Gosh I haven't posted on here for ages. Need a bit of advice. I seem to have a leak between the external door frame and the wall of the caravan. The door is the Hartal type with screw fixings on small brackets on the inside of the caravan. These are then covered by a large white lip seal again on the inside. The caravan is a 2007 Vanmaster, but I have seen the same door on many other makes of caravan. I want to take the whole frame out and reseal it but am not sure whether this is possible. If it's bedded in with non setting mastic then I guess it is. But maybe these frames are bonded in in which case I think I might damage something getting it out. Can anyone offer an opinion? If it is mastic should I reseal with a tape or use a round section of mastic? Many thanks.
