Interior Door Installation Pricing
Interior door installation runs approximately $375–$1,125 per door, scoped to the door type, the jamb condition, and the casing. A straightforward prehung interior door in a sound opening sits at the lower end, while a slab door fitted to a corrected opening with new casing sits at the higher end.
What changes the price: prehung vs slab, door dimensions, jamb condition, casing, hardware, opening correction, and finish work.
Exterior Door Installation Pricing
Exterior door installation runs approximately $550–$2,000+ per door, scoped to the door unit, the threshold, the weatherstripping, and the flashing. A straightforward exterior door sits at the lower end, while a door with opening correction, custom flashing, and exterior trim sits at the higher end.
What changes the price: door unit cost, threshold, sill and weatherproofing, flashing, trim, opening condition, and exterior exposure.
Prehung vs Slab Pricing
A prehung door unit costs more in material but less in fitting labor, because the door is already hung in the jamb. A slab door costs less in material but more in fitting labor, because the hinges are mortised and the strike is aligned to the existing frame.
What changes the price: door unit cost, hinge mortising, strike alignment, jamb condition, and opening correction.
What Makes Door Installation Cost More?
Several choices push a door installation toward the higher end of its range. These are the upgrades and conditions that add labor, material, or fitting complexity.
What changes the price: exterior exposure, opening correction, custom flashing, exterior trim, premium hardware, and damaged jamb replacement.
