A brand new window should not need the hinge adjusted. Have the Marvin service tech out to have a look.

The window is also scraping on the bottom of the sash.

I repeat, have the dealer send out Marvin service before your adjusting things make it worse. Are you sure the window is installed 100% correct?

I dont know. The contractor is blaming the window. My adjusting improved it so I can at least close the window but it feels very tight still. I hope Marvin is better to deal with than my contractor.

I cannot say for sure but my bet is it is not installed properly as I am yet to hear of a Marvin or any other quality window that needed the hinges adjusted upon initial installation.

Are these casements? Does that go away once you engage the lock/latch? Most multi-point locking casements have a progressive action where the bottom catches first and the lock subsequently pulls the rest of the panel in to seal.

If that is not the answer, it could be product OR install related. The general rule is that install is far more likely, but these days with the manufacturing issues across the industry a product issue could very well be a possibility as well.

The best next step is to follow MWM's advice and have a Marvin service rep come out and take a look.

My first thought is a bad install, especially after seeing the scraping on the bottom sash. I would have Marvin come out cause they will be able to speak to either issue(s); bad install and/or window adjustments.

Yep I’m having the Marvin rep come tomorrow to inspect. The installer cant figure it out (which doesnt give me faith in the other windows he installed now).
