Update: the windows are fixed. He charged $25 labor plus the cost of the
glass. He said it took more than an hour to get the putty off the steel
window, the torch didn't do much. Sounds like I made the right decision
letting this one go to the expert.


Indeed. At less than $25/hour he must be working
for the fun of it. I've glazed those windows occasionally
in the past and never found a good replacement for
the clips that hold the glass in, so you probably saved
yourself an afternoon of unsatisfying hassle for $25.
