i recently installed brand new double hung window ( by milguard).
2 of the windows--double double hung--seem to have dificulty
shutting all the way, even though they are plumbed, leveled and
i have to slam the windows down quite forcefully in order for
the latch to catch and lock. i don't have this problem with other
double hung windows in the house..
all the windows rest on the rough sill as suggested by the manufacturer's
what do you think is the problem?
thank you in advance.
