How much does exterior door replacement cost in 2026?

Most homeowners pay $800–$2,500 to replace a standard exterior entry door with installation, including a pre-hung door unit, new hardware, and basic weatherstripping. Steel doors are the most cost-effective at $800–$1,500 installed; fiberglass doors run $1,200–$2,500; solid wood doors run $1,500–$4,000+. Doors with sidelights, transoms, or decorative glass add $300–$1,500 to the project.

What is the best material for an exterior door?

Fiberglass is the best all-around material for most homeowners: it doesn't warp or rot, resists denting better than steel, provides excellent thermal performance, and can be finished to mimic wood grain convincingly. Steel is the most cost-effective and most secure option but can dent and is susceptible to rust if the finish is damaged. Wood is the premium choice for traditional and historic homes but requires more maintenance — repainting or staining every 5–7 years.

Does door replacement require a building permit?

Replacing a door in an existing opening without changing the frame size typically does not require a permit in most jurisdictions. Enlarging the rough opening, adding a new exterior door where one didn't exist, or replacing a door in a fire-rated wall assembly (common in attached garages) does require a permit. Check with your local building department — requirements vary by city and state.

Should I replace just the door slab or the entire door unit?

If the existing frame is square, sound, and not rotted, replacing just the slab (the door itself, without the frame) saves $200–$600 in labor and materials. If the frame shows any rot, moisture damage, or is out of square, replace the entire pre-hung unit — a door hung in a compromised frame will have alignment and weathersealing problems regardless of how good the door is.

How much does it cost to replace a front door with sidelights?

A front door with sidelights (the narrow fixed glass panels on one or both sides) costs $1,500–$4,500 installed for fiberglass, $2,000–$6,000 for wood. The sidelights themselves cost $400–$1,500 depending on size and glass type, plus additional rough opening framing if the current opening needs to be widened. Door-and-sidelight systems are sold as pre-hung units that simplify installation compared to piecing together components.

Exterior Door Replacement Cost Guide 2026: Steel, Fiberglass, and Wood Entry Doors

September 24, 2026 · Cost Guide · 6 min read

Replacing an exterior entry door is one of the highest-ROI home improvement projects — the Cost vs. Value report consistently shows 60–70% cost recovery, and the functional benefits (better security, lower air infiltration, improved weatherstripping) are immediate. A standard front door replacement costs $800–$2,500 installed for most projects; complex configurations with sidelights, custom sizing, or premium materials run $3,000–$6,000+. Here's what drives each cost tier and what to look for when hiring.

Cost by Door Material

Steel Doors

Steel entry doors are the baseline choice for most replacement projects — widely available, affordable, and more secure than fiberglass or wood at equivalent price points. The steel skin is typically 24- or 26-gauge, bonded to a foam insulation core.

Unit cost: $300–$800 for a pre-hung steel door, including basic hardware
Installation labor: $400–$700 for a standard same-size replacement
Total installed: $700–$1,500

Trade-offs: Steel dents more easily than fiberglass. If the painted finish is scratched or chipped and left unaddressed, the exposed steel will rust. Steel doors must be repainted every 5–8 years in harsh climates (coastal areas, high UV exposure). Thermal performance (U-factor) is comparable to fiberglass at similar insulation core thicknesses.

Fiberglass Doors

Fiberglass has overtaken steel as the preferred material for mid-range to high-end replacement projects. It resists denting, won't rust, and can be painted or stained in a way that genuinely resembles wood grain without the maintenance commitment.

Unit cost: $500–$2,000 depending on panel detail, glass configuration, and brand (Therma-Tru, ProVia, Masonite are the major manufacturers)
Installation labor: $450–$800
Total installed: $1,000–$2,800 for a standard door; $2,500–$5,000 for premium configurations with decorative glass

Fiberglass doors have the best long-term maintenance profile of the three materials — they don't warp, rot, or corrode, and the surface can be refinished rather than repainted when the finish shows wear.

Wood Doors

Solid wood entry doors are the premium choice — visually unmatched and structurally excellent when properly maintained. Species range from affordable pine and fir to premium mahogany, oak, and cherry. The primary limitation is maintenance: wood is vulnerable to moisture and UV, and exterior surfaces require repainting or refinishing every 3–7 years depending on exposure.

Unit cost: $800–$3,000+ for pre-hung solid wood doors; custom millwork runs higher
Installation labor: $500–$1,000 — similar to fiberglass but slightly more care required with larger units
Total installed: $1,500–$4,500 for stock designs; significantly more for custom or architectural doors

Door Configurations and What They Add to Cost

Single Door (No Glass)

The baseline — a solid panel door with no glass. Maximum security, maximum insulation value, minimum visual complexity. This is the right choice for side entries, utility doors, or clients prioritizing energy efficiency over natural light.

Single Door with Glass Lite or Decorative Insert

Glass inserts add $150–$600 to the door unit cost depending on size and decorative complexity. Impact-rated glass inserts (required in hurricane zones and recommended for high-traffic areas) add $200–$400 over standard tempered glass. Note that glass inserts reduce the door's insulation value — the U-factor of the glass area is significantly higher than the foam core panel area.

Door with Sidelights

Sidelights are the narrow fixed glass panels flanking the door. They admit more light, create a more formal entry aesthetic, and require a wider rough opening (typically 5'–6' wide versus a standard 3' door opening). If your current entry doesn't have sidelights, adding them requires structural work — widening the rough opening, adding a new header, and rebuilding the exterior trim — which adds $800–$2,500 to the project beyond the door system cost.

Door + single sidelight: $1,500–$4,000 installed for fiberglass; more for wood
Door + two sidelights: $2,000–$5,500 installed for fiberglass

Door with Transom

A transom is a fixed window above the door. It adds height, light, and architectural character to an entry. Transoms usually come as a factory-assembled system with the door unit. Expect to add $400–$1,000 to the unit cost and $300–$600 in additional installation labor for transom framing.

Frame Condition: The Decision That Drives Budget

The biggest cost fork in a door replacement is whether to replace just the slab (the door itself) or the entire pre-hung unit (slab plus jamb, frame, and threshold).

Slab Replacement Only

If the existing frame is plumb, square, and structurally sound, a slab replacement keeps the existing frame and just swings in the new door. This saves $300–$700 in labor compared to a full pre-hung replacement.

Warning signs that slab-only won't work:

Soft or spongy frame material (wood rot)
Frame is visibly out of square (door drags, doesn't latch without force)
Visible daylight around the existing door from inside
Previous door showed swelling or sticking with seasonal temperature changes

Full Pre-Hung Replacement

The pre-hung unit includes the door slab, hinges, frame, and threshold in a single assembly. Installation requires removing the old unit, installing the new one level and plumb, and rebuilding the interior and exterior trim. This is more labor-intensive but ensures you're starting with a fresh, properly sealed system.

Installation Labor: What's Included and What Isn't

Standard labor ($400–$800) typically covers removing the old door, installing the new pre-hung unit, adjusting for plumb and level, installing hardware, and basic weatherstripping. Items that may not be included:

Interior and exterior trim finishing (patching, painting, or replacing casing)
Any rough opening modification
Threshold transition to existing flooring
Smart lock or keypad installation (if replacing basic hardware)
Disposal of old door unit

Get a written scope that specifies exactly what finishing work is included. A low bid that excludes finishing often comes out higher after the additional items are added back.

Security Upgrades Worth Considering at Replacement Time

Door replacement is the optimal time to upgrade security hardware at minimal additional labor cost, since the door is already off and the jamb is accessible:

Grade 1 deadbolt: ANSI Grade 1 deadbolts ($60–$120 for the lock) provide meaningfully higher kick-in resistance than Grade 2 or 3 hardware. The installation cost difference is negligible if done at replacement time.
Reinforced strike plate: A 3-inch strike plate secured with 3-inch screws into the framing (not just the jamb) improves kick-in resistance far more cost-effectively than a stronger lock alone. Cost: $20–$50.
Door reinforcement kit: Wrap-around door reinforcement kits (EZ Armor, Door Armor) reinforce the jamb, hinge, and strike plate areas. Cost: $100–$200 plus minimal installation labor.

What Contractors Handle and What to Verify

Door replacement is within the scope of general contractors, handymen with carpentry experience, and specialty door installation companies. For a standard same-size slab or pre-hung replacement, a skilled handyman is often sufficient. For projects involving rough opening modification, structural work, or high-end custom doors, use a general contractor or finish carpenter with demonstrated experience.

Before hiring, verify:

They've replaced exterior doors on similar home styles and materials (brick vs. wood frame handle differently)
They pull permits if your project requires one
Their quote separates material cost from labor so you can compare bids accurately
