We had a new aluminium sliding patio door and windows installed into a new kitchen extension 3 years ago. However, every winter when the storms arrive rainwater rushes in. The original installer came back when called but couldn't work out root cause. Out of desperation he siliconed round the exterior of the window, which helps for the remainder of that season but degrades before the next season. At this stage he says he cannot afford to keep returning. So we are left with an expensive leaky patio door.
I've had a second builder take a look and he's a little stumped, too.
The weep holes and channels are clear and are not overflowing.
What I believe is happening (based on the affect of the silicone trick above) is that the water that enters the frame down the window is falling onto the runner that the wheels of the door sit upon. This runner has a central silver line. Unfortunately the water isn't falling off this runner into the channel that would take it outside. It seems that there's a little black line that sits somewhat proud of the runner, which I think stops the water falling into the channel. Then, when there's enough water, it overflows the silver line onto the inner side of the runner and thus into the kitchen.
Has anyone experienced this before? Any tricks or tips? The door is from KatUK.
