Homeowners typically pay a broad range to replace exterior doors, with fiberglass and steel leading the market. Main cost drivers include door size, insulation, hardware, finish, and installation complexity. This guide compares price ranges, explains where money goes, and highlights ways to save.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Door Unit (Fiberglass) | $250 | $450 | $900 | Standard 6’8″ x 36″ with foam core |
| Door Unit (Steel) | $200 | $350 | $700 | Combination steel with polyurethane core |
| Hardware & Trim | $50 | $150 | $400 | Knob/lever, lockset, hinges, exterior trim |
| Labor & Installation | $300 | $800 | $2,000 | Removal, fitment, sealing, finish |
| Delivery & Disposal | $50 | $150 | $350 | Old door removal and waste handling |
| Total Project | $700 | $1,700 | $4,350 | Assumes standard entry door with basic hardware |
Overview Of Costs
Price ranges reflect material differences, installation complexity, and regional labor rates. Fiberglass doors generally cost more upfront than basic steel doors but offer better insulation, lower maintenance, and often longer life. Typical installed totals span from about $1,200 to $3,800 for fiberglass, and from roughly $1,000 to $3,000 for steel, depending on thickness, core, and finish. In special cases, custom sizes, decorative glass, or high-end hardware push totals higher. Assumptions: region, specs, labor hours.
Cost Breakdown
Material quality and construction method drive most of the delta between fiberglass and steel. A table below shows common cost components and expected ranges. Per-unit pricing is provided where applicable to help compare options side by side.

What Drives Price
Material core, door thickness, and finish type are the main price levers. Fiberglass doors often feature a foam core for insulation and a fiberglass exterior that resists dents and corrosion, with higher prices for decorative glass or custom colors. Steel doors vary by thickness, insulation quality, and reinforcement; premium models use thicker steel, better cores, and enhanced weatherstripping. Installation complexity, door sizing, and frame work add substantial costs when replacing nonstandard openings or retrofitting new hardware.
Cost Drivers
Regional labor rates and install time can swing totals by 10–25%. In urban areas, installers charge higher hourly rates, but jobs may take similar total time due to access constraints. Rural markets may offer lower rates but schedule delays. Door dimensions matter: a 36″ x 80″ single door is cheaper than a 42″ x 80″ unit or a double-door setup with sidelights. Glass options, security features, and impact-rated models raise both material and labor costs.
Ways To Save
Smart planning and material choice can trim the bill without sacrificing performance. Consider standard sizes to avoid custom milling, select midrange hardware, and choose compressive weatherstripping. If insulation is a priority, fiberglass with an R-Value emphasis can be cost-effective over a steel core that requires additional energy upgrades. Scheduling installation during off-peak seasons may yield lower labor rates and faster availability.
Regional Price Differences
Prices vary by region due to labor markets and installation complexity. In the Northeast, expect higher labor rates and more robust hardware options, with 5–12% higher total costs than the national average. The Midwest typically sees moderate prices, often within ±5–10% of averages. The Southwest can skew lower on labor but higher on material due to decorative glass and climate-specific thresholds. Quantities and availability of standard sizes can also shift final numbers by 5–15% depending on local supply chains.
Labor & Installation Time
Install time influences total cost through crew size and hourly rates. A standard replacement for a 6’8″ door generally requires 4–8 hours with 1–2 installers. Adding sidelights or a decorative transom increases labor hours substantially. For fiberglass, installation may be slightly quicker when doors are lighter or easier to set, while steel units can require more careful alignment with reinforced frames. Labor efficiency and weather sealing are frequent cost drivers.
