Doors and Windows - Plastic door glass mull, where to find.

I noticed pohocker's previous post about installing storm doors over metal doors with plastic mulls.

I did this and my mulls are cracked and warped and no good anymore. We failed to vent them properly.

The doors are 6'-8" x 2'-8" and are insulated hollow metal. The glass covers the door except for 6" top and sides, and 10" on bottom.
We are about to sell our house and I want to replace the mulls and not the doors... $$$.
I would appreciate any help finding replacement mulls as I am not having any luck.
We live in Huntsville Alabama if that helps.
Thanks.

Any home center or glass house should be able to order this part for you, provided you know the brand of door and size of glass. Whether they want to send the plastic frame only... or the plastic frame AND glass is sometimes up to the company. Generally, the glass is glued to the outer plastic frame, which is why they sometimes send it all as one unit.

Thanks.

I guess I will have to actually visit a home center or glass supplier as I can not find any information online. And furthermore, there are no markings on the doors at all to tell me who made them. Usually they are on the door swing side, a plate of some kind. But nothing on mine. Bummer. :wall:
Know where I might find a marking?

Examine the hinge side of the door- sometimes there will be a sticker there. Otherwise, look at the hinges- perhaps they will say "Stanley" or "Therma-tru" or something. If all else fails, get down on your knees and make a sketch of exactly what the weatherstrip looks like on the bottom. Sometimes you can take that into a lumber yard and they can identify the brand of door by the type of weatherstrip used.

As a last place to check, you might look in the corner of the glass for an etching... or some sort of stamp on the aluminum spacer bar in your thermopane... but those markings often belong to the glass manufacturer, not the door company.

And look on the TOP of the door for a mfgr. name. The bottom is going to get cut off to make it fit the threshold. The top isn't going to be disturbed 99% of the time -- that's why the mfgr. will put his name there.
