    What sealant should be used to seal between glass and wooden window frames? The guy who installed new glass on our windows has used decorators caulk by the looks of it. It has cracked and gone mouldy in places where condensation has formed.

    It shouldn't need sealing like that should of been sealed in the rebate but cleaning will stop it going mouldy

    its hard to say if thats caulk or silicone..some white silicones go like that. As gonch64 says , ideally it should be sealed within the rebate , ideally with a double sided glazing tape used too. My guess would be the silicone/caulk is masking either gaps between the frame and glass unit ( potentially frame isn't quite flat enough for the unit to sit flush everywhere , or slight damage to the wood work ). Using a sealant there is far from ideal

    Using any old sealant is a really bad thing as it can dissolve the edge sealant on DGU's. My whole conservatory had been sealed with silicone and the edge seals had all melted on the inside of the units. Just replaced the whole lot. Used glazers tape, silfix U9 to bed each unit in, and Hodgeson HS20 for a capping seal.
