How Much Does Front Door Replacement Cost?

Front door replacement runs $1,200 to $4,500 installed for most homes — with the door unit itself accounting for roughly 60% of that cost. The rest is labor, hardware, and whatever surprises show up in the rough opening once we pull the old frame. I’ve priced out hundreds of these jobs, and the number that shocks homeowners most isn’t the door. It’s the rot they didn’t know was behind it.

What Drives the Cost of a New Front Door

Material moves the number more than anything else. You’re choosing between fiberglass, steel, and wood, and that one decision can shift your total by $1,500 or more. Door size matters too — a standard 3/0 x 6/8 (36″ x 80″) costs a lot less to install than a custom 8-foot entry or a double-door configuration. Then you’re adding glass, hardware, sidelites, and the question of whether your existing frame can stay.

Before I quote anything, I check three things: the rough opening, the sill, and the brick mold. If water has been sitting at the base of that door for years, you’ve got rot. I’ve pulled doors on jobs priced at $1,800 and found $600 worth of framing and sill repair hiding underneath. Get that framing condition looked at before anybody writes a number down. If they won’t check it, find somebody else.

Cost by Door Material

Steel is the budget choice. It dents. It rusts at the bottom once the factory finish gets nicked, and it pulls cold right through the slab into your entryway all winter long. Yes, a basic steel door has a foam insulating core, but the thermal performance doesn’t touch a quality fiberglass unit. In a climate with real winters, steel is a temporary answer to a permanent question.

Fiberglass is what I’d put on my own house. Pella’s Therma-Tru line and Andersen’s fiberglass entries hold up. Marvin makes a wood-clad fiberglass hybrid that’s worth a look if you want the grain and warmth of wood without signing up for annual refinishing. Fiberglass won’t rot, won’t rack, and you can paint or stain it to look like wood. Pull the NFRC label on any unit you’re considering — that’s real thermal performance data from an independent testing program, not whatever the manufacturer printed on the box.

Wood is beautiful. I won’t argue that. I put a solid mahogany door on a craftsman bungalow in Columbia once and the homeowner teared up a little looking at it. Eight years later she called me because it was warped, cracking, and starting to fail at the bottom rail — because nobody had refinished it. Wood demands a yearly maintenance cycle. Skip it and you’re looking at rot inside a decade. Most people skip it.

Labor Costs for Front Door Installation

A carpenter or door installer charges $200–$500 for a clean swap — same rough opening, no structural changes, no rot, pre-hung unit going into a frame that’s still square and solid. That’s a 3-to-4-hour job for an experienced crew.

Find rot, need to replace the frame, or widen the opening and you’re adding $300–$800 in labor on top of that. Replacing a transom or sidelites at the same time adds another half-day. In the Northeast and Pacific Northwest I’ve seen labor-only quotes of $700–$900 on a standard unit — those markets run expensive, and that’s just reality.

ENERGY STAR Performance and What It Costs You if You Ignore It

The Department of Energy puts front door heat loss at up to 11% of a home’s total heating load when the door isn’t performing. The ENERGY STAR program sets minimum U-factor and Solar Heat Gain Coefficient (SHGC) thresholds by climate zone — go to the ENERGY STAR website and look up your zone before you order anything.

How old is your weatherstripping right now? Go check. I’ve seen $4,000 doors installed against a warped frame that leaked just as badly as the original. The frame and the weatherstrip do as much work as the door slab itself. New door against a bad frame is money thrown away.

In most Northern climate zones, you want a U-factor of 0.17 or lower. Pella, Andersen, and Marvin fiberglass entries all hit that mark in their mid-to-upper lines. When a door brand makes thermal claims without pointing you to NFRC-certified test data, walk away.

What I’ve Seen in the Field: Red Flags That Add to Your Cost

• Soft sill plates. Press your thumb into the wood at the base of the current door frame. If it gives at all, you’ve got rot. Plan on $200–$400 in sill and subfloor repair before the new door goes in.
• Out-of-square openings. Old homes settle. A rough opening that’s out of plumb by more than 3/8″ requires shimming and reframing. Your door won’t seal properly without it.
• Incorrect rough opening size. Don’t assume your new unit matches the old one. Measure the rough opening before you order anything. A door that’s 1/2″ too wide means reframing. A door that’s 1/2″ too narrow means filler strips and air infiltration.
• Existing transom or sidelites with failed seals. If you’re keeping the existing sidelites and just replacing the door, check those glass units. Failed IGU seals mean foggy glass and zero thermal performance.
• Non-standard door height. Older homes often have 6/6 (78″) rough openings. Modern pre-hung units are built for 6/8 (80″). That 2-inch difference requires a header modification. Budget $300–$500 extra if that’s your situation.

Hardware, Glass, and Add-On Costs

A basic lockset comes with most pre-hung units. Upgrade to a Schlage or Kwikset SmartKey deadbolt and you’re adding $80–$150. Step up to a smart lock — Schlage Encode, Yale Assure — and you’re at $200–$350 for the hardware alone. Don’t cut corners on the deadbolt. That’s the primary security point on your house. I’ve seen contractors spec the cheapest Grade 3 hardware on a $4,000 door. That’s backwards.

Decorative glass panels add $300–$1,200 to a door unit’s price. They look sharp and they trade away your privacy and sightlines in the process. If you want natural light without putting yourself on display, go with textured or rain glass over clear. Andersen’s full-lite fiberglass entries have good options here — dual-pane insulated glass that still hits NFRC thermal specs.

Sidelites — the glass panels flanking the door — add $400–$1,500 per panel installed. A full surround, two sidelites plus a transom, on a premium Pella or Marvin unit can push your total above $8,000. That’s not a hypothetical. I’ve quoted those jobs and watched homeowners go pale. Know what you’re walking into before you fall in love with a showroom display.

What a Front Door Replacement Actually Pays Back

Remodeling Magazine’s Cost vs. Value Report puts steel door replacement among the top-returning projects in home improvement year after year — 65–75% back at resale on average. Fiberglass entries return a little less on paper but drive stronger buyer perception at the showing. A rotted, sticking front door tells every buyer that this house hasn’t been looked after. A solid new entry with good hardware says somebody cared about the place.

Don’t buy the cheapest unit because the sticker price looks good. A $400 steel door in a harsh climate has a 10-year service life. A $2,200 fiberglass unit runs 40 years. Work that math before a big-box store talks you into their promotional steel special. I’ve replaced those doors. Sometimes twice on the same house.
