Trying to install the pivot shoes on replacement vinyl window. The manufacture sent the parts and recommended to cut the jamb so I can take the broken shoes out and put new one in. Will it weaken the structure of the window frame? Manufacture also mentioned using heat gun to open up the jamb - I don' t like the idea. I like your jamb spreader. Unfortunately, it 's not cost effective because I only need to repair one window - the new one only costs $150. Wish I could rent the jamb spreader, but nowhere to be found.
thank you
Cutting the jamb is a viable option, sure. You just have to be careful not to cut yourself. We do not recommend a heat gun unless there are absolutely no other options available at all. Heat guns can damage the jamb permanently if you aren't careful.
