A common question we get asked is, why is my uPVC door or window frame leaking?
People might not realise that uPVC is designed to allow water to run off the window and door into the frame and then drain out from the frame. Every uPVC door and window will have drainage holes in the frame if the drainage holes become blocked, your door and window will appear to leak.
You might think your uPVC is leaking if you see this:
- Water coming from the bottom of the door.
- Water on the window sill from the frame.
The good news is that there is nothing wrong with your uPVC door or window frame and this is how they are designed to work. You simply need to unblock the drainage holes – and that’s really easy.
Watch our Everest Expert show you where the drainage holes are in the frame and how to clean them.
