Hi all been a member for a while, but my son has just started, and just bought a second hand swift challenger 460/2 from the biggest caravan dealer in somerset.
The van is in great condition, except that now he has it home and over the wet weekend, we have noticed some moisture inside the shower cubicle, for my sins I checked for damp in all the walls but did not check the ceiling DOH!
It looks like moisture is coming in via the lights in the shower, on the basis that leaks dont travel uphill, i checked to find there is a joint running width of the van right over the shower cubicle, it not looking great, with black mould on the right hand side and a possible hole in the mastic, we have rechecked for damp, and ceiling is dry except for about 6 inches from the rear end area of the end bathroom (about 1 sq ft in area), outside that moisture level is very low.
The seal is as per the sketch attached i.e. a 'd' plastic strip on mastic, my plan is to replace it, I have successfully changed the awning rail on my older eldiss of a few years ago.
My question, is the d strip just bedded in the mastic, there are no screws, therefore if i prize it off & remove mastic and then refit with new d strip and roll of mastic (not a mastic gun), is that all i need to do.
Is this how it is attached?
We appear to have minor damp on the floor in the same corner of about 4" square, but not bad, I also intend painting with bitumastic.
Thoughts
PS we are in dispute with caravan shop who said there was no damp. but fear we may lose hence my question
