How to Install an Aluminum Storm Door
A tightly weatherstripped storm door can reduce air leakage around a front door by as much as 45 percent
Q: "I know storm doors cut down on drafts, but are they difficult to install?"
—Maryanne Collins, Islip, N.Y.
A: Not at all. Storm doors are sometimes made of wood or fiberglass, but most—including the Andersen 3000 Series storm I'm installing here—are built from low-maintenance aluminum.
Home centers stock standard sizes and can supply custom sizes in a couple of weeks. Look for models that have weatherstripped mounting rails, which allow you to install the door yourself in about an hour.
Before you start, check the width of the jamb and the thickness of the door casing. If the jamb is less than 2½ inches wide or the casing is less than 1 inch thick, pad out the casing with ¾-inch-wide filler strips. They'll support the mounting rail and allow clearance for the handle when the storm door is shut.
