Hi, thank you for your response.
Not that I know of or can see. (Theres no water ingress marks anywhere else but at the bottom of the windows (above the bifolds))
Flashing looks good.
When we push on the bifolds the water will come in a little between a small gap.
You can see on the pictures...
Hello,
3 years ago we had a lean too extension fitted to the house. Bifold doors with 2 large windows in the roof.
Within 12 months I had to get the builder back due to a bad leak. The leak was coming in at the top of the bifold door, where it meets the frame and pooling on the floor.
