Let's look at your windows drainage systems: Check to make certain the drainage or "weep holes" are always clear of dirt, stucco, sand, or building materials, both inside and outside the window or door in the bottom of the frame.It's normal for water to accumulate in the sill or track area with wind-driven rain. The water is intended to drain to the outside as water builds up or outside pressure subsides.Keep sill or track areas clean of dirt or debris.Use a small, soft bottle brush to clear openings.
