Have 2 bay windows out the front with 48 panes of glass.
Putty looks in good condition but reckon it has dried and shrunk and rain is running down the glass and getting in behind it, and going through to the inside of the house where the interior timber is quite wet
Looking at it, the wooden frame seems to have a lip that the glass sits against with the putty on the outside.
Would I just remove all the old putty and re-apply or do I need something sealing the glass and the lip as well as putty on the outside?
