I am having an issue with the upper fixed window in guest bedroom leaking. Had the glass replaced last February and then during Nicole I had water coming in again. Just had them out again to tell me glue has failed, same issue they said previously. I saw a 2016 post that said this is common in those windows and it is a caulking problem in the mullion. Looking for recommendations for someone who can assess my caulking and fix it. Window warranty wants to put in another new window. I’m not sure that is the problem.
Thank you
