Republic vinyl replacement window service
I have Republic casement and double-hung vinyl replacement windows that are about 15 years old. The double-hungs were terrific for several years but of late have become nearly impossible to open and close. Because they originally worked, and tilt out with ease. I'm thinking the problem is with the balances and not with the window being out of square. Republic is out of business since 2008, but I've read that there are only a few spring manufacturers and it's possible I can find replacements? Is anyone familiar with Republic, and what balance this might be?
I checked in the track for a screw to adjust the opening and don't see any screws in the track whatsoever. The photos are of the balance spring, and also one of the bottom of the bottom sash, where there are screws to attach the sash to a little plastic (pivot?) block. I tried turning those a bit but it didn't seem to help the tension and I was afraid if I went too far the sash would come out of the pivot block and I wouldn't know how to get it back.
A couple of the casement windows were forced closed, while the lock latch was in the closed position, by someone of strength attempting to be helpful during a sudden rainstorm. I could use a couple of parts to get the windows working properly again. There's a horizontal brass (?) plate attached to the crank assembly, with a hole into which a matching peg on the window frame is seated. When the window was forced, it bent the brass plate to the degree the peg pops out unless I open and close the window verrrrry slooooowly. It was a trick even getting the peg reseated in the first place! Am I out of luck because Republic is out of business?
And yes, a good end-of-summer cleaning is in order but have done that in the past, to nearly-new condition, and no joy. Tried rubbing bar soap on the balance spring, too.
