Rain coming in kitchen window 19 January at 3:30PM in In my home (includes DIY) MoneySaving 10 replies 313 views

When we get heavy rain and strong winds in a certain direction we get streams of water down our kitchen window in 3 places across the window on the inside.  It seems to be coming from the part above the p v c and then down the window and ends up in the cill.  Outside it is in 2 or 3 different places.  Anyone give advice on how to solve it?  Thanks

Hi,

if not raining just now, any chance photies outside and in?

pics would help but if its driving rain and water is running down the window from the top it sounds like a seal may have gone or some of the sealant around the frame. is it a opening window or just a fixed window?

It's a fixed window large pane just off to get pics.

The inside one is a bit dark but outside is better

Hard to tell for sure from the pics, but the first and simplest thing to do is take a look at the brown sealant around the edges of the window (especially the top edge).  If it's cracked or pulling away from either the window or the brickwork at all, replace it.  Dead simple DIY job (though it can be a bit of a fiddle to remove the old stuff, especially from brickwork).  Buy a couple of tubes of good-quality exterior-grade silicone and re-seal it.

For the sake of a couple of hour's work and a few quid for some sealant, it's got to be worth a try.

It's not set into the wall very deeply.

I wonder if the water is running down the top overhang and into a flaw or two in the seal.

With the heat wave and now freezing it could well have caused it to pull away in places.

Easy to do and cheap. You could even just do a quick cover of sealant until the weather is nicer to get the old stuff out and put in new.

Thanks for replies, gives me something to go on.

one option is to wait for a nice dry day then get a hose on it methodically, dont spray the whole window, work in sections.  There arent that many places it can be getting in along the top of the window frame although water has a habit of not always acting straight down - i had a slow leak in a pipe once which caused a water stain on the ceiling in the adjacent room. lots of floorbaords later finally found the leaky joint.  as suggested though, replacing the sealant is an easy job and once you've stripped the old stuff off it may be obvious where water is getting in

I suspect it is coming from the overhang.

Remove old silicone, renew silicone and then fit some upvc quadrant trim on, then seal again, thus double sealed. Providing there’s enough overhang, you can get 9mm quadrant, or a flat trim cut do.
