Leaking windows

adonis10

We have lounge and bedroom window leaks, which looks to be caused partly by failing render outside and gaps underneath the window sills inside. Upstairs it appears to emanate from higher up, as shown in pics below. Any advice? Full window replacement, maybe? If so, would this result in new plaster being needed for the walls?





Two above show where the water is coming from in the lounge.





These final two show where the water is running from in bedroom - you can see this is underneath sills and running down wall. Bear in mind these two were taken when it happened during decoration, but it is the same issue. Foolish not to fix it when it happened previously, I know.

You need to get the cause of the leaks fixed. Then let the plaster dry out and then a determination can be made on the condition.

I fixed an issue for someone, damp patch coming through corner of room, due to small hole in back of cast iron downpipe. It took a couple of months to properly dry out. The plaster was no worse off and the new paint job over it looked good.

Just don't rush to decorate over it. Let it dry out properly.

Thanks.


Where would you look first? Who would be good to get in to investigate? I don't want people in who are not impartial as they will simply say it is x in order to get a sale.

It's very hard to see anything from those pictures I'm afraid.

You're rught, a window salesman will just offer to cure it with new windows. I'd get 3 different general builders in and then compare their diagnoses....

What is there outside? Gutters aove? Downpipes? Drain below?

If there's cracked render on the external wall, yes, water gets in behind the render and then canoot escape, so it gradually penetrates the wall and eventually you get penetrating damp inside.

Or as you say, poorly fitting windows which may just need sealing. Or rotten woodwork on window cills?

All are possibilities, but there's no point decorating till you've identified the problem, fixed it, and (as Tyler says) it's all dried out.

edit: you might do etter on the In My Home board, or on one of the DIYNOT boards.
