We have a bay window that juts out from the house and has some supports on the outside wall that it rests on, if that makes sense! I decided to give it all a lick of paint and when I looked on the underside there is a small gap all the way round it. Is this there for ventilation or can I seal it up?
The gap runs all the way along from left to right, not the best picture though!
