shouldn't Marvin windows/doors last more than 20 years?
I have some Marvin swinging patio doors that started leaking at the bottom recently. These were installed when the house was built 20 years ago. I've had someone try replacing the weather stripping at the bottom but this had no impact. I'm now looking at replacing these doors. I have another older home and as we've needed to replace doors and windows I've always gone with Marvin. So far no problems but none are 20 years old yet.
I'd like to replace these leakers with Marvin sliding french doors but I find myself asking - why am I replacing a failing Marvin product with more Marvin? Could it be an installation problem? The contractor who has been working with me to fix/replace didn't mention anything looking to be wrong from that perspective.
