Storm door installation cost

Installing a storm door costs $250 to $900, typically around $450 including the door. Labor alone is $100 to $300. It is one of the cheapest exterior improvements there is, and one of the few where the wrong choice actively damages what it is protecting.

What it costs

The overheating problem nobody mentions

This is the reason to read before buying.

A full-view glass storm door in front of a dark-colored entry door, facing south or west, creates a sealed air space that reaches 140 to 180°F in summer. Fiberglass and steel doors delaminate, warp and blister at those temperatures, and most entry door manufacturers explicitly void the warranty if a full-glass storm door is fitted in that situation.

The rules that keep you inside the warranty, roughly:

• Avoid a full-view glass storm door on a south or west facing dark door with no shade
• Use a ventilating model where the glass slides or swaps for screen, so heat can escape
• A porch, an overhang or a light-colored door reduces the risk substantially
• Check the entry door manufacturer's actual wording, because it varies

If your entry door faces north, or sits under a deep porch, this is not a concern.

What it is actually for

A screen door for ventilation is the honest main use. A retractable screen model gives you glass in winter and screen in summer from one door.

Weather protection. It keeps rain and wind off the entry door, which meaningfully extends the life of the finish on a wood or painted door.

A modest energy benefit. The trapped air layer is worth something, roughly like adding a single glazed pane. On a well-sealed modern entry door it is marginal; on an old leaky one it is noticeable.

Security, on heavy-duty models with a steel frame and a proper lock, which is a different product at a different price.

Light and appearance, for people who want the front door open with the storm door closed.

Choosing one

Frame material. Aluminum is standard, light and adequate. Steel-reinforced or solid steel frames cost more and do not flex, which matters on a wide or exposed door.

Glass and screen arrangement. Full-view with a removable panel means storing a glass panel somewhere for six months. Retractable screen models keep both in the door, which is much better in practice and costs $150 to $300 more.

Handedness and swing. It must match the entry door's hinge side. Getting this wrong is the most common ordering mistake.

Closer quality. Two closers rather than one on a wide door, and a hold-open mechanism. A cheap single closer is what makes a storm door slam and eventually pull its hinge screws out.

Sweep and expander. The adjustable bottom expander is what makes the seal work on an out-of-square opening, which most are.

Frequently asked questions

Can I install one myself?

It is a realistic DIY job: the door comes pre-hung in its own frame and screws to the existing brickmould or trim. Two things matter. Check the trim is sound before you screw into it, and take time squaring the frame, because a storm door that is not square will not latch.

Will it void my entry door warranty?

It can, on a full-glass model over a dark door in direct sun. Read the entry door manufacturer's wording before buying, and prefer a ventilating model where there is any doubt.

Is it worth it for energy savings?

Modestly, and it is not the main reason to buy one. Over an old, leaky entry door in a cold climate the difference is noticeable. Over a modern insulated door it is small.

How long do they last?

Fifteen to thirty years. The closers and the screen are the parts that wear and both are cheap to replace.

Does it help with security?

A standard aluminum storm door does not; the frame is light and the glass is ordinary. Purpose-built security storm doors with steel frames and laminated glass do, and they cost $600 to $1,500.
