Exterior Door Replacement
Your front door is the focal point of your home's exterior and a critical barrier for security, weather protection, and energy efficiency. Replacing a worn or outdated exterior door enhances curb appeal, improves insulation, and can reduce energy costs significantly.
Types of Exterior Doors
Exterior doors come in several material types, each with distinct advantages for different applications:
- Fiberglass: The most popular choice for entry doors. Durable, energy-efficient, low maintenance, and available in wood-grain textures that convincingly mimic real wood. Costs $1,000-$4,000 installed.
- Steel: The most secure and affordable option. Excellent insulation, fire-resistant, and dent-resistant with modern finishes. Costs $500-$2,500 installed.
- Wood: Classic beauty and character. Best suited for covered entries or mild climates. Requires regular refinishing. Costs $1,500-$5,000+ installed.
- Sliding patio doors: Space-efficient with large glass panels for natural light. Vinyl frames are most common. Costs $1,200-$4,000 installed.
- French patio doors: Elegant double-door design for patios and decks. Costs $1,500-$6,000 installed.
What Door Replacement Costs
The total cost of exterior door replacement includes the door unit, frame, hardware, and professional installation. Here are typical price ranges:
- Standard entry door (fiberglass or steel): $1,000-$3,500 installed
- Premium entry door (decorative glass, sidelights): $2,500-$6,000 installed
- Sliding patio door: $1,200-$4,000 installed
- French doors: $1,500-$6,000 installed
- Storm door: $200-$600 installed
If the existing door frame is rotted or damaged, replacing the full frame adds $200-$800. Adding sidelights or a transom window increases both material costs and installation complexity. Energy-efficient doors with foam-core insulation and weatherstripping provide the best thermal performance.

A professional door installation ensures proper fit, weather sealing, and security. Poorly installed doors draft, stick, and can be a security vulnerability. When choosing a contractor:
- Verify precise measurement: Exterior door openings are not standard. The contractor should measure height, width, and depth at multiple points
- Check weatherproofing methods: Proper flashing, threshold sealing, and weatherstripping are essential to prevent water and air infiltration
- Ask about structural adjustments: If your opening is out of square (common in older homes), the installer needs to shim and adjust the frame for a proper fit
- Confirm hardware quality: Entry door hardware should be Grade 1 or Grade 2 rated for security. Verify the lock type and deadbolt are included
Frequently Asked Questions
A standard entry door replacement takes 4-6 hours for a professional installer. Patio door replacements may take 6-8 hours. Full-frame replacements add 1-2 hours.
Fiberglass doors with foam-core insulation offer the best energy efficiency. Steel doors are a close second. Wood doors are the least insulating unless they are solid hardwood, which is heavy and expensive.
While possible for experienced DIYers, professional installation is recommended. Improperly installed exterior doors can leak water, draft air, and compromise home security. The cost of professional installation is relatively small compared to the door itself.
Fiberglass and steel exterior doors last 25-30 years. Wood doors may need replacement sooner (15-25 years) depending on exposure and maintenance. Replace earlier if you notice drafts, difficulty latching, or visible damage.
