What’s in these numbers
Each total is a typical job, priced the way a contractor’s estimate is priced:
- A pre-hung interior door unit: the door already hung in its frame, set in the opening, with the old door and frame taken out.
- Overhead and profit: 20%, the standard markup on a contractor’s estimate.
- Sales tax on the materials, at the state’s average rate.
Not in them: painting or staining the door and trim, new hardware sets, casing upgrades, resizing an opening, and double, French or barn doors.
Pre-hung or slab
- Pre-hung: the door comes hung in a new frame, with hinges, ready to set in the opening; used when the frame is damaged or the door is a new size.
- Slab only: just the door, hung on the existing frame. Less material, but the hinges and latch have to line up with the old frame.
What moves the price
- The door. Solid-core, paneled, wood species and 8 foot doors cost more than a standard unit.
- Double and specialty doors. French, Dutch, barn and double doors are priced on their own.
- Finishing. Paint, stain and new hardware are extra steps.
- Where you live. Pick your state in the box above.
