Just got up after a busy night shift and it's been raining heavily for past 6 hrs.
Water drips are coming from the top of the window recess... the plastered section where the Venetian blinds are fixed.
It looks as if it's coming from inside the cavity?
Upstairs window is dry.
How / why is this happening? And what can I do with more rain expected ;@)
incidentally wind is an easterley which is pushing rain direct against wall...
Terrace with wooden gutters?
concrete lintel above has blown? (NOT a builder btw)
Cheers for input mate...No semi detached
Plastic gutters that have been cleared but not great ;@/
if it's the guttering why no leaks upstairs though?
Hmm, if it is the guttering, they will have a visible leak and it will be running down the wall. If not that, check the pointing, esp around the cill above and check the silicone seals around the windows
How old?? Could be cavity bridging but would be surprised if it hadn't happened before. Also am I right in thinking this is a ground floor window leaking on the head of the window recess?
It happened once last year.
1930's house
Yep head of recess
pointing?
air brick in the front façade and wind blow rain?
Bruneep
don't do that to me
I'm embarassed enough as it is
Earlier this year fixed a similar problem on a 1970 house - problem was the pointing above the window had turned mainly to dust and the harder problem to see was the small gap in the silicone at the end of the window sill of the window above which we proved was the problem by testing with a watering can.
Thanks guys...
Wind eased and no longer dripping.
Will contact a builder tomorrow
Where are you located? If it's pointing and silicone, it's an easy diy fix
Check the guttering for leaks next time it rains
some photos may help?
Sounds more like water penetrating the bricks due to the wind, running down the cavity and not getting out through the drain holes thus eventually bridging the cavity. Pointing may be contributing but it's as likely the water's working through the bricks. Check your drain holes. The silicone sealent shouldn't be too much of an issue, more cosmetic and to stop drafts unless the windows have been very badly fitted, i.e. don't fit. If the poinitng etc is OK consider giving the bricks a coat of Thompsons waterseal or similar. The reason it's happening downstairs and not upstairs is the there is a larger surface area of brick above the downstairs window, therefore more water penetrating through to the cavity.
common fault on older houses usually pointing above window area
It's a 30's house there may well be no cavity and there certainly won't be any cavity trays above windows let alone weep holes. It's clearly wind driven rain getting in, as stated above via poor pointing or missing silicone.
You need to see if there are any Cavity Trays installed (fit into the brickwork) we're in the process of replacing windows and are having to have them fitted!
To many unknowns so hard to pin point.
First port of call would be pointing.
There will be no cavity trays in a 30s house 🙄
You never know 😉
1. pointing missing above window or some other rain penetration
2 damaged or not installed cavity tray
1)no cavity tray.
2)cavity tray with no perp end drains/vent
3)failed/poor seal at junction of window frame and wall
There will be no cavity trays in a 30s house
+1
Cavities in small areas of wall between down/upstairs windows are often full of cement or rubble, so any water getting through pointing or render on window sill could end up on inside leaf. there won't be any cavity trays and anyway they often end up being installed sloping towards the interior.
Ffs there will be NO cavity trays!!! Read the previous posts or just .....dont talk bollox!!
