How to remove replacement casement window

Need directions to finding book or internet instructions on removing a vinyl casement replacement window.

 

Is this window a replacement window, or a retrofit window? (When it was installed, was the original frame removed, or left in place?)

If it was a replacement window, you may find that the outside trim was removed and the window was installed using the nail fin.

If it was a retrofit window, you may find that it is held in place with 3" screws through the side of the frame into the trimmer studs of the rough opening of the window.

Don't know of any book or on-line instructions. This site may be your best bet. But, since you can see the window and we can't, you will have to determine HOW it was secured in place before we can help you.

 

Lefty, Thanks for response on removing my casement window.
It has the four screws through sash frame and fastened to rough opening. If windows never have both these screw fasteners and fins, then I believe the window is simply stuck fast with caulking. Will try to remove as much as I can and then try to pull out window. Appreciate your help, this is a great web site.

4 screws through the frame into the rough opening -- the window was retrofitted. Removing the 4 screws is the easy part. What sort of caulking was used to seal the window to the frame or siding will determine how difficult removing it will be. Some contractors use silicon for this (in my opinion --"FOOLS"). A better choice would be something like Sikaflex or Vulkem. But that will make removal more difficult for you. They work better because they seal better and won't come unsealed nearly as easily.

 

Lefty you mentioned Sakaflex and Vulkem;
never heard of them.
are those product same as Butyl caulk?
