Discussion Board Forum for Vinyl Windows

Is it ok to do this? What needs to be done when replacing with a finless? I know how to get them out. Some siding will be removed. Wouldn't it make it much easier in the future to replace the window? Why do they even use the fins in new construction? Is it that much better at being water tight or so...

You can do it . I did the same thing wth the same windows. Just take your time. Most important things: plumb , level, square and tight fit (but not too tight) measurement is important.

I am replacing some vinyl windows with new vinyl windows. I have all the molding etc. off. I can see all the studs. If I measure at 3 points for the width and height, how much do I need to take off the measurement? Thanks
