hi i am having problems with the windows in my static caravan i purchased it second hand, the makers of the caravan are trying to fix the problem but they did not make the windows and at first they said the drain holes hadnt been knocked out therefore the water was just running down the cavity and soaking the carpet and skirtingboard they "fixed" this but the problem is still there they are coming back to it but is it possible that the drain holes are in the wrong place
