We have two Marvin Elevate 8‘x12’ sliders and they both leak air so much. The wind is extremely loud sounding because the sliders are bowed and the weather stripping is not sufficient for these doors. I contacted the place where I ordered the windows from and they said a Marvin sales rep will come out to look at it. He also said he’s heard of this before and that they have a new, better fitting, weather strip to replace our old one with. It’s been a few months and still no one has come out to look at it. Anyone else have this issue? On cold days in New England, it feels like an air conditioning unit when I walk up to the door. This can’t be normal? I am starting to really regret going with Marvin for our new home.
