Hey Guys, A squirrel was trapped in my fathers house and tried to eat his way our of a couple windows while he was away on vacation. Seems I need to replace the sashs on two windows which are beyond repair. The current windows are standard 1960s single pane double hung units, no weights/pulley. Is there a simple sash replacement kit that can be installed, or am I looking at an entire replacement window. I'd love to just pull the sash and install a new sash liner and be done with it. All input is appreciated. Thanks, Bryan

Hello everyone first time poster and hoping to be able to pluck some brains or get an idea on how to properly install the rope or if I am using the correct rope... I have a bathroom window that won't stay open, I did a google search but none seem to be exactly the kind of design the way the window is held up or down. I guess I don't know what or how to call it... The tracks looks something like this: [url=http://www.homedepot.com/p/Prime-Line-28-in-Sash-Window-Channel-Balance-FA-2740/202625178]Prime-Line 28 in. Sash Window Channel Balance-FA 2740 at The Home Depot[/url] The spring isn't as long but the problem is trying to figure out how to properly wrap and install the rope and if I am using the correct rope.. I went to the nearby Lowe's and the guy said it was an old window and didn't have that particular kind of rope but found some medium duty twisted nylon rope about the same size and said it should work as it was rated for 30 lbs and was waterproof. The old rope looked like a standard brown rope. I try following the picture but.. The first time I tried to wrap it it was to loose. The window would stay open however every time you touch it or sneezed it would slowly drop down until it was closed. The second time I tighten everything it was too tight and had to fight the window to completely close. The rope snapped in one week and as I was trying to untie everything apparently the ropes around the pulley was under quite bit of tension and when I try to unwrap the rope it snapped shooting the spring backwards.. My questions are... 1. Am I even using the correct rope in the first place? It says good for 30 lbs.. 2. How do you determine how "tight" the rope should be when putting everything back together. Should stuff be tight already? or should stuff be a little loose? What is the proper way to put everything back together? Do you have to allow some slack before tying both ends? When I was putting the window back in, the first time I allowed the base where the window would clip on in the center of the frame and then tighten and put the window back in... which allowed to much slack. The second time I moved the track where the windows clip on much higher up and shorten the rope.. However when it came down to push the window back down... it was very hard.. You can feel the spring being pulled and wanting to retract back.. I believe I might be just installing the rope incorrectly.. I was wondering if someone had a diagram of how the rope is suppose to go and how "tight" or lose the ropes are suppose to be for installation.. The pulleys are the same as the link above.. It looks like it is a simple project but I just can't figure it out... Appreciate any tips or idea's At this rate even if the window stays only half way would be a victory.. it is a bathroom window that we open for fresh air to get in and close during use and winter time.. It doesn't help that the toilet is right next to the window... The house was built in the Mid 30's Gambrel style house.
