That was my first thought as well. My reply back to him was "you're kidding
right?". And he said no.. he does it that way all the time. This wouldn't
be the first thing he's done that demonstrates he's a bit of a hack. I just
hope to hell my new window doesn't leak everywhere and the stucco patch fall
out when the rainy season hits.... Has a general contractor's license
too... .. Ah well.. live and learn.. glad I caught this one before we
installed.
