I was wondering if I could get some help from this forum, as I belong over in the masonry forum and I'm terrible with carpentry.
I had a room plastered in my house, and the company opened a few of the windows. They are double hung Anderson windows. The top section of the window no longer is able to support itself... it just slides down if I unlatch the safety lock. None of the other windows operate like this, and they are only 5 years old. I dont see any way to "lock" the upper part so it stays up. Was some compression seal broken? Are they broken or am I missing something?
Thanks for any help
