We have lived in this house since late 2019. There are seven timber windows mostly on the NE and NW faces of the house (see photo below, windows numbered 1 to 7). In 2022 we got double glazing retrofitted and shortly after the exterior professionally painted. During the retrofitting one of the installers said there was a bit of rot at the bottom of the frame in window 3. He said he dug it out and put some bog in it and thought that would probably work. After about 18 months I noticed peeling paint. I contacted the painter to ask them to come have a look. I've had no luck getting them around. Then I noticed that the exterior concrete sill had no slope at all. Which seemed bad. So we had a guy come round to refit them with a good slope. I hoped the water would shed better. Since then the peeling has gotten much worse and there is sign of water damage inside — way beyond anything you would expect in a double glazed home with two heatpumps and floor and ceiling insulation. I think there is a serious water tightness issue in these windows. I've also noticed that the exterior sills that sits above the concrete sills also have no slope on them. Basically we want out windows and house watertight and weatherproof. Our preference is to remove the bottom windows and sort it out and wall it up and keep only the top windows. This would give us more wall space inside. But depending on the price we're open to other less extreme options. Windows 3, 4 and 6 are the large windows with the dimensions you can see in the picture. Windows 1, 2, 5, and 7 are smaller, only as big as the smaller "half" of the bigger windows. Really keen to get this sorted as I am worried that the problem is growing with every day of rain we're having this summer.
