Installing a Storm Door on exterior door with snap on PVC brick molding
-Mark-

I installed an exterior door a couple of years ago that has a snap on brick molding (brick molding snaps into a groove along sides and top of jamb). I now want to install a storm door. Can I safely screw the storm door frame into this PVC brick molding ? Any advice ?

Thank you,

- Mark G.

I wouldn't screw anything into PVC.

Really ? Ok, so there are a lot of new exterior doors being made this way these days. How is someone suppose to install a storm door with this setup ? Do I have to remove the brick mold and replace the whole thing with wood ?

You can screw into the brick molding but it's not structural like wood, so the supplied screws will not hold. You need screws which are long enough to pass through the molding and bite into the framing behind it which with normal framing would be at least 2 1/2" long. It would be wisest to pre-drill some pilot holes at least as large as the minor diameter of the screws through the molding to preclude splitting. I'd seat the hinge side of the frame (which holds the weight) on a bead of caulking for some extra bonding and support too; use "Duo-Sul" by Siroflex as it's almost as good as glue once cured and it sets fast.

Perfect, thank you for taking the time to provide this advice. This was helpful and much appreciated.

You can screw the storm door to the PVC brickmold, as long as it is not a security storm door. Use 1 5/8 or 1 3/4" screws. Longer screws will not hit any structural support.

I have done this and even though it was not a security door, a group of thieve worked really hard to get the door off, but were unable to get through the exterior door as I reinforced it before installing the security door.

I beg to differ; do the math:

Storm flange: < 1 /16"
Brick Molding at thickest part: 1 - 1/4" (it's actually thinner where the flange mounts)
Wall sheathing normally: 1/2" Nominal, actually more like 7/16". Tyvek thickness insignificant.
----------
Total distance to framing: <1 - 13/ 16"
Thread length on supplied screws: ~1"
----------
Screw length to equal holding: <2 - 13/16"

Since that size isn't made a 2- 3/4" or 3" length screw will suffice, and the 3" will compensate for 3/4" sheathings. You will have to aim the screw slightly outward toward the stud to be sure you get a good bite but you can hit the framing with commonly available screws. I'd rather do this than to chance having the brick molding un-snap. And it will be far more secure than being screwed into the PVC alone even if it doesn't unsnap. All doors should be mounted as securely as is reasonably possible- there can be a huge amount of force involved on them when slammed or when the wind catches them. I've never seen a problem with a door being mounted too securely but I run into the opposite almost daily and the usual cause is from the screw(s) stripping from what it's screwed into. Security door or no, mount it well just because you can and it's easy to do.

Your math is fundamentally wrong. The brickmold mounts to the edge of the door frame which in turn is approximately flush with the edge of the siding, or the inside edge of the bricks. Since most storm doors have screw holes along the inside edge the frame, the holes are about a half inch from the outboard edge of the brickmold. You would need a 3" or longer screw going in at a 45 degree angle to hit any support at all.

The screws will hold in PVC better than you would think. I recommend putting your security in the primary door rather than the storm door. They are so flimsy to begin with that reinforcing them just isn't worth the trouble.
