How Much Does Door Installation Cost?

Door installation costs vary dramatically depending on the type, material, and complexity of the project. A basic interior door replacement can cost as little as $150, while a high-end exterior or french door installation can exceed $4,000. Understanding the cost breakdown helps you budget accurately and avoid surprise expenses.

The total cost includes the door unit itself, hardware such as hinges, knobs, and locks, any required framing modifications, and professional labor. In 2026, labor rates for door installation typically range from $150 to $500 per door depending on complexity and your local market.

Door Types and Price Ranges

Interior doors are the most affordable, ranging from $150 to $500 installed. This includes hollow-core and solid-core options for bedrooms, bathrooms, and closets. Exterior doors cost more due to weatherproofing and security requirements, typically ranging from $500 to $2,000 installed. Patio doors offer wide access to outdoor spaces and cost $800 to $2,500. French doors, with their glass panels and elegant design, range from $1,500 to $4,000. Sliding glass doors are a space-efficient alternative to french doors, costing $700 to $2,500.

Door Materials Compared

Wood doors offer timeless beauty and excellent insulation but require regular maintenance and cost more upfront. Fiberglass doors mimic the look of wood while providing superior durability, weather resistance, and minimal maintenance. Steel doors are the most affordable exterior option and provide excellent security, but they can dent and conduct heat. Each material has distinct advantages depending on the location and purpose of the door.

Installation Complexity Factors

A standard installation involves removing the old door and hanging the new one in the existing frame. This is the simplest and least expensive approach. Moderate complexity includes minor frame adjustments, shimming, or weatherstripping upgrades. Complex installations require enlarging or reducing the rough opening, adding a header, or modifying the framing structure. The most complex jobs involve structural modifications that may require a building permit and professional engineering.

Hardware and Finishing Costs

• Interior door knobs and hinges — $20 to $80 per door
• Exterior deadbolts and handle sets — $50 to $300 per door
• Weatherstripping and threshold — $20 to $60 per exterior door
• Painting or staining — $50 to $150 per door
• Trim and casing — $30 to $100 per door

Frequently Asked Questions

Can I install a door myself?

Interior prehung doors are a manageable DIY project for homeowners with basic carpentry skills. Exterior doors require more expertise due to weatherproofing, security, and structural considerations. Incorrect exterior door installation can lead to air and water infiltration.

How long does door installation take?

A professional can install a standard interior door in one to two hours. Exterior doors take two to four hours. Complex installations involving framing work can take a full day or longer.

Should I replace the frame or just the door?

If the existing frame is square, plumb, and in good condition, replacing just the door slab saves money. If the frame is damaged, warped, or out of square, replacing the entire prehung unit is more reliable and often easier.

What is the best exterior door material?

Fiberglass is the best all-around choice for most homeowners. It resists denting, warping, and rotting while providing good insulation. Steel is the best value for security. Wood is ideal for historic homes or when aesthetics are the top priority.

Do I need a permit to replace a door?

Most door replacements that use the same rough opening do not require a permit. However, changing the size of an opening, adding a new doorway, or modifying a load-bearing wall typically requires a building permit and inspection.
