Understanding the Cost to Add an Exterior Door

For construction professionals, accurately estimating the cost to add an exterior door is essential. Current estimates for a standard installation range from $1,400 to $1,800 for a prehung steel door in an existing opening, while creating a new opening can cost between $3,000 and $4,500. These figures include material, labor, and finishing costs.

Factors Influencing Cost Variations

Costs can vary widely due to several factors:

  • Door style and material (fiberglass, steel, wood, glass panels)
  • Wall type and required structural framing
  • Siding, trim, and interior finish match-ups
  • Hardware, locks, smart sensors, and weatherstripping
  • Local code requirements and permit fees
  • Site accessibility and demolition complexity

Average Baseline Pricing in Residential Construction

For a standard 36" prehung steel door, expect costs of $1,400–$1,800 in regions like Buffalo, NY. Creating a new opening can push costs to $3,000–$4,500 due to additional framing and repairs.

Detailed Cost Breakdown

  • Door & Hardware: $250–$1,200+
  • Rough Carpentry: $300–$900
  • Weather Barrier & Insulation: $80–$180
  • Exterior Siding & Trim Repair: $150–$700
  • Interior Drywall & Paint: $120–$400
  • Disposal & Cleanup: $50–$150
  • Permit & Inspection: $35–$150

Regional Labor Multipliers

Labor costs account for 40–60% of the total cost to add an exterior door. In Buffalo, carpentry rates are around $60 per hour, while in suburban Colorado Springs, they may be closer to $48.

Hidden Costs Professionals Should Consider

  • Electrical reroutes for lights or outlets
  • Masonry cuts on brick veneers
  • Upgrading to smart locks or low-E glass
  • Temporary weather protection

DIY vs. Professional Installation

While DIY may seem cost-effective, professional installation ensures precision and warranty protection. Professional carpenters prevent common issues like hinge bind and ensure proper flashing.

Energy Efficiency and ROI

Replacing an old door with an insulated fiberglass panel can reduce heat loss by up to 28%, saving approximately $320 over five winters in Buffalo.

Financing and Scheduling Tips

  • Combine projects for discounts
  • Book during shoulder seasons for lower rates
  • Use milestone invoicing for payment flexibility
