Exterior Doors - A Guide To Buying Used or Surplus

If you need a new front or back door but want to keep the cost down, you have three routes: buy a secondhand or salvaged door, buy surplus or unsold stock from a local door company, or buy new and have it installed. A typical exterior door replacement runs about $550 to $2,400 installed, so a secondhand or surplus door can save real money, but only if it fits your opening and seals well. Here's what each option costs, where to find affordable doors near you, and how to make sure a used door will actually work.

What Exterior Door Replacement Costs

Item Typical cost
Exterior door installed (typical project) About $550 to $2,400, averaging around $1,450
Fiberglass front door installed About $1,265 on average
Wood exterior door installed About $600 to $2,920, averaging around $1,755
Installation labor About $40 to $90 an hour; prehung doors take less time
Secondhand or salvaged door Often a fraction of new, but you may need to add a frame, hardware, weatherstripping, and installation

Ranges are national estimates; frame repair, sidelights, glass, and custom sizes raise the price.

Option 1: Local Door Companies and Installers

Searching for a local door company near you is often the fastest way to an affordable, properly installed door, especially if you ask the right questions:

  • Ask about unsold, surplus, and discontinued doors. Many door dealers and installers have doors left over from cancelled orders, discontinued styles, or showroom displays, sold below list price.
  • Get measuring included. A door company can measure your opening and tell you whether a standard prehung unit fits or whether you need a custom size.
  • Get installation and a warranty in one quote, including removal and disposal of the old door, trim, and hardware.
  • Compare at least three companies in your area. Prices for the same door and installation can vary widely.

Option 2: Surplus, Overstock, and Closeout Doors

Home improvement stores, building supply yards, and door outlets sell overstock, returns, and closeout doors at a discount. These are usually new, so you get modern weather sealing and energy efficiency. Check for shipping damage, confirm the swing direction, and ask whether a damaged-box or returned unit still carries a warranty.

Option 3: Secondhand and Salvaged Doors

Used doors can be a bargain, and older solid-wood doors can add real character. You'll find them at:

  • Nonprofit home improvement stores that resell donated building materials.
  • Architectural salvage yards, which specialize in reclaimed and vintage doors.
  • Local online marketplaces and classifieds, where homeowners and contractors sell leftovers from remodels.
  • Demolition and remodeling contractors, who sometimes sell doors they remove.

Will a Secondhand Door Fit? Check These First

  • Size: measure your opening's width, height, and jamb depth. A common U.S. entry door is 36 by 80 inches, but older homes often have non-standard sizes.
  • Slab or prehung: a slab is just the door; a prehung unit includes the frame and hinges and is much easier to install correctly.
  • Swing direction: confirm whether it opens left or right and in or out.
  • Hardware holes: check where the lock and handle bores are; mismatched holes need patching or a new lockset.
  • Condition and seal: look for warping, rot, cracks, and how well it will seal. An exterior door that doesn't seal will cost you in energy bills.
  • Lead paint: painted doors from homes built before 1978 may contain lead paint. Don't sand or scrape them yourself without proper precautions.
  • Interior vs. exterior: never use an interior door outside; it isn't built for weather or security.

DIY or Professional Installation?

Replacing a prehung door in an existing, square opening is a manageable project for an experienced DIYer. If the frame is damaged, the opening isn't square, or you're fitting a used slab into an old frame, a professional installer is usually worth the cost, because a poorly hung exterior door leaks air and water and won't lock reliably.

How to Get the Best Price

  1. Decide on prehung or slab based on your frame's condition.
  2. Measure carefully and take photos of the opening.
  3. Call local door companies about surplus, discontinued, and display doors before you buy new.
  4. Get three written quotes that list the door, hardware, labor, removal, and disposal.
  5. Budget for extras: weatherstripping, threshold, paint or stain, and a new lockset.

The Bottom Line

For the best value, start by asking local door companies about unsold and surplus doors, compare a closeout or overstock door, and consider secondhand only if it fits your opening and will seal well. With installed exterior doors commonly costing $550 to $2,400, the right affordable option can save you hundreds, as long as the door is the right size and properly installed.
