I have sliding glass windows on Aluminium tracks and when it rains heavily (especially when it is windy) the rain water comes in on the window sill & wets the wall underneath.
The water seems to be filling the window tracks & then entering. Any thoughts on how to fix this?
I am adding a photo of the window tracks. The weep holes seem present and unblocked? There's a trio of aligned holes on the track rails. This is a three panel horizontal sliding window.
For approx. a 6 ft horizontal span of window there seem to be three sets of holes laterally. Do I need more holes? Larger holes?
What else could be the problem? The water influx seems to only happen when it rains heavily and on windy days. Being in a subtropical climate the thunderstorms can be quite severe.
