We get asked about our front door and storm door pretty often. When we were trying to decide on doors we drove around our neighborhood taking pictures and really liked one of our neighbor's doors. We took the picture to Edward Hines Lumber, and they were super helpful looking through books with us to find similar door styles.
We ended up buying our front door from Simpson Door Company: And our storm door from The Combination Door Company. It has a glass front for winter and a screen front that we use the rest of the year.
We ordered both of them through Edward Hines. They came unfinished, and we stained and sealed them. We were on a really tight budget for our siding, windows, and roof so we could do them all at one time, but this splurge on the doors was totally worth it - it really makes all the difference in the look of the entire house.
