I'm replacing 7 windows in a 1950 house. The house is wood frame with cedar shake siding that has been covered in vinyl siding. The current windows are aluminum, probably '70s vintage. I want to replace the aluminum windows with vinyl windows.
I got a bid for $4600 from one company that uses no-flange windows. They have a 25-year guarantee on product and installation.
The next lowest bid was from a company which uses only windows with flanges. They told me the "glue-and-screw" windows will eventually leak (because the caulk will eventually fail), while their windows, with flanges, won't. However, the guarantee is similar. Their bid was for almost $7000.
I don't want to spend the extra $2400 if I don't have to, but I don't want to sentence myself to a future of fixing leaky windows by going with the cheap option now.
Are "glue-and-screw" flangeless windows a bad idea?
One other consideration: I want to remove the vinyl siding and return the house to its cedar shake shell. I realize the window detailing was probably ruined when the vinyl went on -- but do either of these replacement options have a bearing on that?
Thanks in advance for your help!
