My parents live in a maisonette on 2nd floor and there is another house on top. In December 2020 following a period of heavy rain, water started entering one of the rooms, with water dripping from the white window trim and surrounding areas.
Landlord has done a bunch of work to try and fix the problem - they redid the above house balcony which is directly above the bedroom, they applied waterproofing paint and did tests with coloured water to try and trigger the problem.
A few days ago, again after a period of heavy rain, water started dripping again from the same place, so basically back to square 1.
Back in summer 2020, they did some work which involved attaching scaffolding to the building and left behind holes which were not filled after work finished. Could this be the source of the problem? I can't find much information about it but it's a hole directly above the window area and surely can't be good for the building? They are called putlock holes according to Google
Couple of pictures - 1st one shows an attempt to look inside the leftover hole and 2nd shows it in relation to room - you can see internal damaged area in 2nd picture.
