Marvin sliding door weatherstripping

A quick learner from Columbus, Ohio says:
I have an oversized (8 foot) Marvin sliding patio door. It's about 10 years old and the outside weather strip is in need of replacement. Who do I call to it replaced. I tried to call a local distributor several times and they never return my call, apparently they don't want to do it. Can you please tell me where I can buy a replacement for it so I can attempt to do it myself.

You can try to browse through the replacement weatherstripping catalog section or you can post a quick photo of your old weatherstripping so that we can see what it looks like.
A home owner from Scarsdale, New York says:

I am looking to buy weather strips for my patio doors (brand: Marvin Integrity). Currently when it gets cold, the air from outside comes inside the house. Can you get back to me on which product to buy. Please see attached pictures of the doors. Please get back to me as soon as you can.

Hi Jenny. Thank you for submitting your photos. Please take a look at the Swisco 58-008 Prime Door Seal. This looks like it should work as a replacement.
