In one of the bedrooms, the bottom corner of the double glazing windows becomes damp when it rains heavily. I THINK it's because there's a bad seal on the outside of the windowsill? I can only guess, the wet sits on plaster then dries up pretty quickly when the rain stops.
There's an old conservatory with slanted roof below the window so it's not as simple as getting a ladder up there and checking out the sealant, if I get someone out it'll have to be full scaffolding to get there (unless they have hobbies involving hanging out of windows)
I guess my real question is am I at any significant risk of the entire frame coming out because of the faulty points? Is there a way I could fix it from the inside? Stick some kind of foam or sealant in the hole on the inside (I poked it while wet and now there's a hole don't ask)
I've added some photos of what it looks like when rained through, as well as the aforementioned hole. (the crack in the plaster in the last photo was because the plaster was put on then left to dry in the blazing hot sun and it didn't like it)
