Labor Costs
Door installation labor costs $100–$400 per door for standard pre-hung doors and $300–$800 for exterior doors or custom installations. Replacing a door in an existing frame takes less time than installing a new opening.
Factors That Affect Doors Cost
Door Type
Interior hollow-core doors are the most affordable, while solid wood exterior doors and French doors are the most expensive. Specialty doors like pivot doors and oversized entries command premium prices.
Material
Fiberglass and steel exterior doors offer the best value for durability and insulation. Solid wood doors cost 2–3 times more but offer unmatched aesthetics and craftsmanship.
Frame Modifications
Installing a door in an existing frame costs less than creating a new opening or widening a doorway. Structural changes require header installation and drywall repair, adding $500–$2,000.
Glass & Features
Doors with sidelights, transoms, or decorative glass inserts cost more than solid panels. Energy-efficient glass with Low-E coatings adds to the price but improves insulation.
Hardware & Locks
Basic door hardware costs $30–$75, while premium handles, deadbolts, and smart locks range from $100–$400. High-security locksets and electronic entry systems add to the total cost.
Tips To Save Money On Doors
Choose Pre-Hung Doors
Pre-hung doors with the frame included are faster and cheaper to install than slab doors that require custom fitting. They also ensure a better seal and smoother operation.
Select Fiberglass Over Wood
Fiberglass exterior doors cost 30–50% less than solid wood, are more energy-efficient, and require less maintenance. Many fiberglass doors convincingly mimic the look of real wood.
Replace Multiple Doors at Once
Contractors often offer per-door discounts for multi-door projects. Replacing all your interior doors at once is more cost-effective than doing them one at a time.
Keep the Existing Frame
If the door frame is in good condition, installing a slab door in the existing frame saves $100–$300 per door compared to full pre-hung replacements.
