There are three basic steps to installing a storm door. These are relatively universal across all brands and models, but you should always follow the installation instructions for your specific storm door.

Then cut and install the hinge-side Z-bar: Place the Z-bar against the opening on the hinge side of the door and mark the top. Measure the height of the door opening, from the bottom of the rain cap to the top of the sill.

questions to ask

Q. How long does it take to install a storm door?

A handy homeowner can install a prehung storm door in about 4 hours or less. If your door needs to open using an extender kit, you may want to plan on an additional 30 minutes to an hour. Many home centers also offer professional storm door installation.

Q. Do storm doors come with a frame?

Today’s prehung storm door kits come with a frame and are offered in popular and standard door widths, including 30-, 32-, 34- and 36-inch sizes. Double-door kits and custom-order sizes are also available.

Q. Is wood core or aluminum better for storm doors?

Many storm doors are made from a wood core covered with vinyl, PVC, composites or aluminum. These wood-core doors offer increased durability and insulation, but when subjected to extremely harsh conditions, the wood core can rot over time. Aluminum, on the other hand, will not rot or corrode, although it may pit and show scratches, and is generally more expensive. Each material has benefits and drawbacks, so buyers need to balance cost, aesthetics, durability, and desired features.
