Hi everyone,
We live in a 2 story detached house and have had a problem with our south west facing gable end which has 2 window openings on the second floor, and a lean too extension on the ground floor. Its in the opening to the extension where we are suffering with a leak under heavy rainfall.
The extension is only a year old but have had the leak for the past 5 years with many people coming and trying to fix it. It seems to be making its way down the inside edge of the outside block, hitting the lintel and dispersing out along it.
Things we have had done over the past 4 ish years:
1.We have had the whole gable end re rendered with 2 coats of waterproof render! (before the extension)
2.Had dry verge system installed on roof, (as noticed original cement had come loose and cracking)
3.We had a national company come in and replace all our windows (what a **** up that was!) butchered the house, which we then had "repaired". However i recently removed the trim on outside of the biggest window on the gable end to find a 1.5 inch gap around both sides and across the top with no insulation and could see the back of internal wall/ plasterboard.
I noticed that the top of the window frame had a puddle of water on it all the way along. I have filled with expanding foam, trimmed it back, masticed it, then bought & applied fresh trim and sealed.
I haven't looked at the other window as it all looks good plus there is no trim as i guess it fits correctly! So didn't see the point in exploring there!
I guess im just asking / checking that there isn't another possible cause for a leak?
I think the problem is the bigger window being incorrectly fitted! im not entirely sure its level as water seems to run to the left on the external sill, which is more or less above where it leaks.
There is a cavity tray but that's above the opening downstairs, which is lower than the flashing on the new lean too roof. My last idea i have with all this is to cut a block out and fit a new cavity tray higher than the flashing for the roof!
Any help or advice is welcome as am at my wits end with this !
