Had the home depot install a storm door (which was also purchased at the home depot).
Service man came and took measurements, and since it was an outdoor project he didn't require us to be home which was nice (talked over the phone instead.) A few weeks later the door came in and he quickly installed it. Zero problems, door fit perfectly, which was an issue with the last door we had which was measured improperly.
Only issue is that from the time the measurements were taken and the time the door was fully installed, there was quite a wait or at least a greater wait then we had expected (a month for a door). In the end though the no fuss installation made the wait well worth it.
