I wonder if anyone can suggest a good way to seal an old window frame in a stone house from the rain please.
We've discovered that the rain comes through under the bottom part of the window frame that sits on top of a flat granite block. The are no drainage channels or ridges to stop the rain driving in, especially in the right hand corner. There's a picture here: http://www.flickr.com/photos/siwilson/6143683012 /
I've raked out all the old mortar, various bits of silicone sealant, old socks etc. from underneath, and re-mortared with a hydraulic lime.
In heavy rain it still seeps underneath as of course the lime is porous. Also over time the wood's going to move etc. and cracks will open up.
For now, I've just blathered on water repellant, but I don't think that's a good long term solution. Can anyone think of a solution that won't look too gash. So far I've thought of either slapping silicone sealant all over it (which I think will look awful), or white flashing tape (ditto).
