Aluminium sliding window that faces south. In a storm the inside track fills with water. No visible weep holes on the exterior. How does the water drain away? Should i be concerned?
It kind of looks like the weep holes are covered up on the outside.. This is the most obvious cause that I can think of. It looks like the outside sill is rendered - if the window was installed prior to render, then it is feasible that the weepholes were rendered over.
Also, weep holes can become clogged, so if the weepholes are found, check there is nothing blocking them (dirt, debris).
There doesn't appear to be any weep holes or flashing above the window either - it is possible that if this is not flashed correctly, then water could be getting in at the window head, and trickling down to the inside track, which is then holding water.
Hope this helps
thank you for your reply.

It's great that you've received fantastic advice from @jaga. Looking at the photos you posted, it seems that there are no weep holes. Traditionally weep holes use to be drilled into the corner of the aluminium rail on the outside end. The modern ones now have a stamped cut out at the corner to let water out. However, before you drill a hole in your window frame, I suggest investigating thoroughly every part of the aluminium rail before attempting to drill. I suggest only a small hole using a Drill Bit rated for steel use.
Here is a handy guide to help you drill into the aluminium.
