I ordered an Andersen 4000 36" x 80" storm door which has yet to arrive. In preparation, I'm going to have to build out on the mullion between the door and sidelights on both sides. My door handle sticks out too far to allow installation of the storm door onto the mullion. I'm including a couple of pics to demonstrate what I'm talking about. The mullion is 2" wide, and 35" wide measured from the inside surfaces (39" wide measured from the outside surfaces.

Any info on how to go about prepping for this storm door.

 

Is there a roof over this porch area? Have you considered placing the storm door some distance from the entry door to make an enclosed porch?

 

I have installed storms but only on the door section and always the door knob of the storm hits the main door knob so the storm needs to be spaced out some. You probably also need to space out to allow room for the door closer cylinders.

For low maintenance I make the spacers from PVC molding or 3/4" thick sheets that I rip into strips but wood can also be used and is probably easier to get and less expensive. I keep the storm as close as possible to the door so it does not look like it's hanging out in space and so there is not a gap down at the threshold.

A issue you may run into with storms covering the storms is how will you clean the windows? Will you have access to the narrow space between the storm and main door side lights?

 

Here are some links to older threads on this topic where this has been covered before.

Thanks, XSleeper, those do help. One issue is that once the question is answered and the job is done, people don't often put up "after" photos to show how things turned out. Those would be helpful. I'll try to do that with this post.
