Thanks for the advice. Can anyone tell me what the lumpy ugly whitish blackish material that the POS used previously to seal the vent might have been? (I can provide a picture though it will have my white silicone over it, it will still give an idea of what the original seal job looked like.) Reason I ask is I wonder if whatever he used allowed the leaking and subsequent damage.
Also can anyone please give me an idea of what it might cost to have a professional remove the whole thing and reseal.... one of you made mention of making a good living doing this sort of thing....thanks again for all your help.
Janet
