So you dodged a bullet, let this be a wake up call for ya.
Remember another little thing tho, more often than not, you will find windows that have an over hang that rain won’t touch or even directly under the eaves sometimes, the glaziers or whoever installs them won’t caulk it or seal it at all because they know they can get away with it.
I’ve seen this countless times and have had a ton of leaky windows.
Kurt Kempton had an awesome idea I plagiarized years ago…on his estimate form on the very bottom there was a very cool disclaimer that said something along the lines that if water gets in the house that theres a very slight chance, if it rains and it leaks then it will probably leak when the glass is cleaned as well and to let them know before hand so they can avoid that area.
Crazy how things get blown out of proportion sometimes eh?
