Front door replacement cost calculator

A prehung steel entry door commonly costs $600 to $1,800 installed. Fiberglass is often $900 to $3,000. Wood is often $1,500 to $4,500. A sidelight adds roughly $500 to $1,500. A double door is closer to 1.7 times a single, not twice, because one opening still has one head. The driveway gate is on the fence calculator, not here.

Diagram, part by part

Front door replacement: every numbered part explained

The front door replacement drawing above has 9 numbered parts, from Prehung door to Glass, energy and impact ratings. Each card below frames one of them, and after you run the calculator it shows what that part adds to your estimate.

1. 1 Prehung door

   $600–$4,500 installed

   A prehung door comes already hung in its own frame with hinges, weatherstripping and a threshold, so it installs square and seals well. The old door and frame come out, and the new unit is shimmed, fastened and insulated in the rough opening.

   What moves it: Door material, glass, style and whether the rough opening needs work.

   On the quote: Ask for the brand, model and swing, and whether the frame is wood, composite or rot-resistant.

2. 2 Sidelight

   $500–$1,500 per side

   Sidelights are narrow glass panels beside the door, built into the same unit. Each side adds to the unit cost and needs a wider rough opening, which can mean reframing the wall.

   What moves it: Number of sidelights, glass type and opening width.

   On the quote: Ask whether the wall must be widened and how that is priced.

3. 3 Second slab (double)

   about 1.7×

   A double door uses two slabs in one frame, one active and one fixed with bolts. It costs about 1.7 times a single door, not twice, because the frame and installation are shared.

   What moves it: Door material and the opening width.

   On the quote: Ask how the fixed slab is secured and whether a multi-point lock is included.

4. 4 Sill pan, threshold & flashing

   Part of a proper install

   A sloped sill pan under the threshold and flashing tape around the frame carry any water that gets past the door back outside instead of into the floor framing. It is the step most often skipped.

   What moves it: Floor and wall type and exposure to driving rain.

   On the quote: Ask whether a sill pan is installed and how the frame is flashed.

5. 5 Lockset & haul-away

   $120–$350

   The lockset, deadbolt and strike plates, plus hauling away the old door. Longer strike screws into the framing make the door much harder to kick in.

   What moves it: Hardware grade and finish.

   On the quote: Ask for the lockset grade and whether reinforced strike plates are used.

6. 6 Casing, caulk and paint

   Usually a small extra

   New casing inside, trim outside, caulk and paint finish the opening. Factory-finished doors cost more but skip on-site painting.

   What moves it: Trim profile and whether the door is prefinished.

   On the quote: Ask whether painting and staining are included.

7. 7 Door material

   Steel to wood, about $600–$4,500

   Steel doors are the least expensive and secure but can dent and rust at cuts. Fiberglass resists dents and weather and can look like wood. Solid wood looks best but needs refinishing and protection from sun and rain.

   What moves it: Material, glass and decorative options.

   On the quote: Ask for the door's insulation value and the finish warranty.

8. 8 Rotted sill or subfloor

   Found during tear-out

   Old doors that leaked often leave a soft sill or subfloor that only shows when the threshold comes out. Repairing it first gives the new door a solid, level base.

   What moves it: How long the old door leaked and how far the rot spread.

   On the quote: Ask for an allowance or a per-hour rate for rot repair found during removal.

9. 9 Glass, energy and impact ratings

   Changes the unit price

   Glass in the door or sidelights can be standard, low-E for energy, privacy glass, or impact-rated in hurricane zones. Rated units cost more but may be required by code or give insurance credits.

   What moves it: Your climate and wind zone, and the glass area.

   On the quote: Ask for the U-factor and any impact or product-approval rating in writing.

Entry door

Price the opening, not the picture in the catalog

The installed price includes the unit, the labor to set it plumb, exterior trim, a lock, and hauling the old door. It grows when the rough opening is rotten, the size is not standard, or the code wants impact glass.

What to measure before you order. These close-ups are crops of the same AI-generated illustration.

01Slab and swing

The size and the swing

Width, height, and which hand. A wrong swing is a restock fee. Measure the old slab and the jamb.

02Sidelight glass

The glass

A sidelight or a door lite changes energy and breakage. Coastal wind-borne debris ratings are a different, more expensive unit.

03Sill and threshold

The wall under the sill

Soft rim board and a rotten jamb are common. A unit price for carpentry keeps the bid honest.

Before you sign a quote or file a claim, verify these three details

Unit

Steel, fiberglass or wood, prehung, size written.

Lock and trim

Included, or a separate finish carpenter.

Rot

Who repairs the sill and the trim, per hour or per piece.

Front door replacement cost (2026)

Front door or gate: two different jobs

An entry door is part of the dwelling envelope: weatherstripping, a sill, a lock, and a rough opening in a wall that is supposed to stay dry. A gate is a fence leaf. People search both as “main entrance.” Only one of them is on this page. Gates, including a driveway gate, stay with the fence tool because the posts, the operator and the coverage (often Other Structures) are different.

Prehung is the right default. A slab-only swap into a twisted jamb looks cheap and leaks. Standard sizes — 36 by 80 is the common single — keep you in this band. An arched top, a true divided sidelight wall, or a pivot door does not.

Storm and impact damage are where insurance shows up. A door that has been swelling for a decade is wear. If wind took the door or a tree did, photograph the opening before it is boarded, and price board-up on the tree-and-tarp page if that visit already happened.

Worked example: fiberglass single with one sidelight

Storm damage, rot, and the deductible

• Wind, hail or a falling object that destroys the door can be a dwelling claim, subject to a wind deductible that is sometimes a percentage of Coverage A. Run the hail deductible calculator if that percentage applies to the opening too.
• Rot and a bad sill are maintenance unless a covered opening let the water in and you can show it.
• An upgrade from a steel slab to a wood double is not fully owed. Like-kind is the argument.
• The garage vehicle door is the garage door calculator. Do not mix the two invoices.

Front door replacement cost by region

The calculator's default front door replacement job, repriced for each of its six regions. At the national average it runs $1,520 – $4,850; South / Lower Midwest is the lowest at $1,322 – $4,220, and West Coast metro is the highest at $1,976 – $6,305, a gap of about $1,370 at the midpoint.

What “Door” does to the price

Every other input stays at its default and only “Door” changes. The cheapest choice, Steel, prehung, comes to $1,220 – $3,650; the most expensive, Wood, prehung, comes to $2,120 – $6,350.

What “Opening” does to the price

Every other input stays at its default and only “Opening” changes. The cheapest choice, Single door, comes to $1,020 – $3,350; the most expensive, Double door, comes to $1,650 – $5,450.

How age changes the front door replacement claim payout

Using the default job, a $1,000 deductible and a 30-year expected life. At 10 years old, about $1,062 is held back as depreciation; a replacement cost policy releases it after the work is finished, while an actual cash value policy keeps it.

Quote checklist: 6 items to verify

Front door quotes are easiest to compare by unit, installation details and trim.

1. Unit details. Brand, model, material, glass, swing and size.
2. Prehung or slab. A prehung unit with frame, or only a slab hung in the old frame.
3. Sill pan and flashing. How water is kept out under the threshold.
4. Rot repair. An allowance or rate for sill and subfloor repair.
5. Hardware. Lockset, deadbolt and reinforced strike plates.
6. Trim and finish. Casing, caulk, paint or stain, and haul-away.

How long the job takes

Ask the installer to secure the opening the same day; a front door should never be left boarded overnight.

Common mistakes that raise the cost

• Measuring the slab, not the opening. Prehung doors are ordered by rough opening size.
• Skipping the sill pan. Water under the threshold rots the floor framing.
• Short strike screws. Short screws let a door be kicked in easily.
• Ignoring the swing. Changing the swing affects hardware, trim and furniture.
• Leaving wood unfinished. Bare wood doors swell and crack within a season.

Ways to keep the cost down

Standard sizes and simple glass keep prices reasonable.

• Keep the same size. No reframing.
• Choose stock steel or fiberglass. Quick delivery.
• Skip sidelights. Lower unit cost.
• Paint it yourself. If unfinished.
• Reuse good hardware. If it fits.
• Fix rot early. Smaller repairs.

Signs a front door needs replacing

Weatherstripping can fix some problems, not these.

• Drafts after new weatherstripping. Frame issues.
• Rot at the sill. Water damage.
• Sticking or sagging. Frame movement.
• Cracked panels. Security concern.
• Poor locks. Weak security.
