Door cost overview
New openings add framing, drywall, and often permit work on top of the door's own installed cost. Load-bearing walls also require a header and an engineer's sign-off, which pushes them well above a like-for-like replacement.
How it works
Select door type
Choose interior, exterior entry, patio/sliding, or garage door.
Choose material
Steel, fiberglass, wood, and composite each have different price points and durability.
Add hardware and finishing
Locksets, hinges, and door frames add to the base door cost.
Door Installation Cost by Type
| Door Type | Cost Installed |
|---|---|
| Interior door | $226–$824 |
| Exterior / patio door | $500–$1,900 |
| Front / premium entry | $650–$3,300 |
Per door installed, including the door, labor, hardware, and threshold. New framing, sidelights, and smart locks add cost.
What's included — and what's extra
Usually included
- Door slab or pre-hung unit
- Standard hardware & hinges
- Installation labor & leveling
- Basic threshold & weatherstripping
Often extra
- New framing or re-sizing the opening
- Sidelights / transom / storm door
- Smart lock or premium hardware
- Old-door removal & disposal, painting
What moves the price
- Interior vs. exterior. Interior doors are cheapest; front and patio doors cost the most (weather sealing, security, glass).
- Material. Hollow-core interior is budget; solid-core, steel, fiberglass, and wood climb from there.
- Pre-hung vs. slab. Pre-hung (door + frame) installs faster; a slab into an existing frame is cheaper but fussier.
- New opening. Cutting a new opening or resizing adds framing, drywall, and permit cost.
Front Door Replacement Cost
Whether you call it a front door replacement or a front door installation, it's the same job and this calculator prices it the same way — "replacement" and "installation" are used interchangeably for swapping an existing front door, and only diverge in cost if the new door needs a resized or newly framed opening (see "Replacing a Door vs Installing a New One" below).
A front or premium entry door runs $650–$3,300 per door installed — the highest of the three door categories this calculator covers, because entry doors carry security hardware, weather sealing, and often glass or sidelights that interior and standard exterior doors don't need. Labor is roughly 30–35% of that total; the rest is the door unit itself and hardware.
Replacing a Door vs Installing a New One
"Replacement" and "installation" get used interchangeably, but they're different jobs priced differently. A straight replacement reuses the existing rough opening and often the existing frame — a slab door can go into a frame that's still square and in good condition, which is the cheaper, faster path. A new installation — a door where none existed, or a resized opening for a wider door, sidelights, or a transom — requires framing, drywall, and sometimes a permit, which is why the calculator's cost overview lists new-opening framing as a separate add-on rather than folding it into the base door price. A smart lock upgrade is a hardware add-on either way, not a reason by itself to reframe the opening.
Repair or replace?
Repair a sticking or squeaky door, a bad strike plate, or worn weatherstripping — cheap fixes. Replace when the door is rotted, warped, badly drafty, damaged, or you want better security or curb appeal. A new insulated exterior door also trims energy loss.
Material types, hiring & warranty
- Fiberglass: best insulation and no rot/rust — top pick for entry doors. Steel: strong and secure, dents; look for a Grade-1 deadbolt. Wood: beautiful, needs maintenance. Hollow-core: interior use only.
Questions to ask — and red flags:
- Pre-hung or slab, and is the opening square/plumb?
- Is framing, disposal, and painting included?
- Bundling multiple doors? Ask for the multi-door labor discount — many installers won't volunteer it.
Warranty: quality doors carry limited lifetime warranties on the slab and finish; confirm the installer's separate labor warranty and register the product.

About this calculator
How much does door installation cost?+
Door installation costs $226–$1,900 per door depending on type. Interior door installation runs $226–$824 including labor. Exterior door installation costs $500–$1,900 due to weatherproofing, security requirements, and more complex framing. Front entry doors cost $650–$3,300 installed.
How long does it take to install a door?+
A pre-hung interior door takes 2–4 hours to install. An exterior door replacement takes 4–8 hours. New rough opening framing adds 2–4 hours. A full entry door with sidelights can take 6–12 hours. Most single-door projects are completed in one day.
What is a pre-hung door vs. a slab door?+
A pre-hung door comes with the frame, hinges, and sometimes hardware already attached — easier and faster to install, especially for new openings. A slab door is just the door panel without frame — cheaper but requires an existing, in-good-condition frame to fit into. Pre-hung is recommended for exterior doors.
Can I install a door myself?+
An experienced DIYer can install an interior slab door replacement in an existing frame in 2–3 hours, saving $100–$250. Exterior doors require precise weatherproofing and plumb installation — mistakes lead to drafts, water intrusion, and security issues. Pre-hung exterior doors are best left to professionals.
What type of door is most energy-efficient?+
Fiberglass doors are the most energy-efficient — they have the highest R-value (R-5 to R-6), don't warp or rust, and can mimic wood grain. Steel doors with foam core are a close second (R-5 to R-7) and are more affordable. Solid wood has lower R-value (R-2 to R-3) and can warp with moisture.
Does replacing an exterior door increase home value?+
Yes — front door replacement returns 65–75% of its cost in added home value. A new steel entry door at $500–$1,900 installed is one of the most cost-effective curb appeal improvements available.
How much does it cost to replace a front door?+
Front and premium entry door replacement costs $650–$3,300 per door installed. That range covers the door unit, standard hardware, labor, and threshold/weatherstripping — the wide spread reflects material (steel vs. fiberglass vs. wood), glass, sidelights, and security hardware.
Is replacing a door cheaper than a new door installation?+
Yes, generally. A straight replacement that reuses the existing rough opening and frame skips the framing, drywall, and permit work a new opening requires. Cutting a new opening adds those trades on top of the door's own installed cost, and a load-bearing wall also needs an engineer's sign-off and a header, which is why new openings land well above a like-for-like swap.
