Exterior common entry doors

[Keaton Vols]

I am replacing entry doors on my fourplex. I live in North Dakota so we get all the weather extremes. Was wondering if it worth it to go with fiberglass doors to prevent rust on steel doors? Or if anyone has any experience with fiberglass, good or bad

Hi Keaton,

I had one on a personal residence and liked it a lot. I'm actually about to replace the front door on my apartment building and was probably going to go with Fiberglass.  I live near Chicago, so we get all 4 seasons and a ton of moisture.  Fiberglass door held up well.  Fiberglass is going to cost 100-300 more, but the door I'm replacing is probably close to 50 years old, so for that length of time, a little more on the cost isn't the end of the world. 

I'm interested to hear what NEGATIVE things people have to say about fiberglass entry doors.  I don't see any drawbacks but haven't ruled that out.
