Why Install a Storm Door?

Storm doors serve as a protective layer over your exterior entry doors. They shield the main door from weather damage, improve energy efficiency by creating an insulating air pocket, and allow ventilation when you open the main door. A quality storm door can extend the life of your entry door by decades while reducing energy costs.

In 2026, storm door prices range from $100 for a basic aluminum model to over $500 for a premium full-view door with retractable screens. Installation adds $75 to $250 depending on whether the frame needs modification. For most homeowners, the combination of energy savings and door protection makes storm doors a worthwhile investment.

Storm Door Types

Full-view storm doors feature a single large glass panel that maximizes natural light and showcases your entry door. They are the most popular style for homeowners who want to show off a decorative front door. Ventilating storm doors include operable glass and screen panels that let you control airflow while keeping insects out. Retractable screen doors use a roll-up screen that disappears into the frame when not in use, offering a clean look and full visibility.

Storm Door Materials

Aluminum storm doors are the most common and affordable option. They are lightweight, corrosion-resistant, and available in many colors. Wood storm doors offer a traditional look and good insulation but require more maintenance. Vinyl storm doors provide excellent insulation and weather resistance with minimal maintenance, though they come in fewer style options.

Energy Savings from Storm Doors

Storm doors create a dead-air space between the storm door and the entry door, reducing heat transfer. This insulating buffer can reduce energy loss through the door by 25 to 50 percent. The actual savings depend on how well-sealed your existing entry door is, your climate, and the quality of the storm door. Homeowners in cold climates typically save $50 to $150 per year per door.

Installation Considerations

• Measure the door opening carefully — storm doors come in standard sizes but require precise fit
• Check the condition of the brick mold or exterior casing that the storm door attaches to
• Ensure adequate clearance for the storm door to open fully without hitting railings or walls
• Consider the direction of prevailing winds when choosing hinge placement
• Avoid installing storm doors on doors that receive direct afternoon sun in hot climates, as trapped heat can damage the entry door finish

Frequently Asked Questions

How long do storm doors last?

A quality aluminum storm door lasts 25 to 40 years with minimal maintenance. Wood storm doors can last just as long but require periodic painting or staining. The hardware and closer mechanism may need replacement every 10 to 15 years.

Can I install a storm door myself?

Yes, storm door installation is one of the more approachable DIY projects. Most storm doors come with complete installation kits and detailed instructions. A handy homeowner can complete the job in two to three hours. The key is accurate measurement and ensuring the frame is plumb and square.

Do storm doors work in hot climates?

Storm doors can trap heat between the storm door and entry door, which is beneficial in cold climates but potentially damaging in hot climates. In hot regions, choose a storm door with a low-E glass option or a ventilating model, and avoid installation on south or west-facing doors that receive direct afternoon sun.

What size storm door do I need?

Measure the width and height of the door opening (not the door itself). Most exterior doors are 32, 34, or 36 inches wide and 80 inches tall. Storm doors are available in these standard sizes. For non-standard openings, some manufacturers offer custom sizing.
