The exterior of my wooden windows, which are old but fairly solid, were sanded and painted last summer by professionals, using Dulux trade undercoat (2 coats) and gloss. A few weeks ago I noticed some of the paint was bubbling up slightly, and when I investigated I found I could peel the paint off by hand and underneath the wood was very damp. In fact it was wet in places - I could squeeze water out of it by pressing on it. As we had not had rain for about 6 weeks prior to this, I am wondering where the water came from. It is only along the bottom edge of the frames (opening and non-opening). In some places it may have been caused by the putty separating from the glass and allowing rain in, although in other places the putty looks sound. I noticed that the damp appears to come from the middle out, i.e. it's wetter about an inch into the frame than it is on the outside. The opening windows are also damp along their outside bottom edge, even where the paint looks sound.
Sorry - bit long winded - but I am now in the process of repairing the frames and replacing the putty, and I want to be sure I haven't missed whatever might have caused the problem. Anyone got any idea what's happened?
