Door Installation & Replacement Cost in Montclair, NJ

Updated August 11, 2026 • Montclair NJ Guide

Exterior door installation in Montclair typically costs $900–$3,500 installed depending on material, with solid wood front doors — common on Victorian and Colonial homes — running toward the higher end. Interior doors run $250–$900 each. Montclair’s older housing stock adds two wrinkles most national cost guides skip: non-standard door openings that need custom sizing, and historic district review for street-facing changes. This guide covers real local pricing and both of those factors.

TL;DR — Quick Estimates

Steel entry door: $900–$1,800
Fiberglass entry door: $1,500–$2,800
Solid wood entry door: $2,500–$5,000+
Storm door: $300–$900
Interior door (each): $250–$900

Exterior Door Cost by Material

Material	Notes	Typical Cost (Montclair)
Steel	Most affordable, durable, good insulation; limited styling options	$900–$1,800
Fiberglass	Can mimic wood grain, low maintenance, good middle-ground choice	$1,500–$2,800
Solid wood	Authentic look for period homes; needs more maintenance, higher upfront cost	$2,500–$5,000+
With sidelights or custom sizing	Common on Montclair's older, non-standard openings	+$500–$2,000
Storm door (add-on)	Installed separately or alongside a new entry door	$300–$900

Labor typically runs $150–$500 of the total per door for a straightforward like-for-like swap, more if the frame needs to be replaced or the opening isn't standard size. A patio or sliding glass door is a different category entirely — those run $1,500–$5,000+ installed depending on size and glass type, and are usually quoted separately from a standard entry door.

Why Montclair Doors Cost More Than the National Average

Non-standard openings

Montclair's Victorian, Colonial, and Craftsman homes were built before modern door sizing was standardized, and many original openings are taller, narrower, or otherwise off-spec compared to today's stock sizes. Custom-ordering a door to fit adds cost and lead time versus grabbing a standard size off the shelf.

Frame condition

An old frame that's settled out of square or has rot at the sill often needs full replacement — a new prehung unit rather than just swapping the door slab in the existing frame. This is a common surprise once an installer actually inspects the opening rather than just measuring it.

Historic district review

Homes in Montclair's four locally designated landmark districts (Town Center, Upper Montclair, Pine Street, Watchung Plaza) can require Historic Preservation Commission review for a front door replacement that changes its design or appearance, which can push homeowners toward wood or wood-clad doors with specific profiles rather than a standard off-the-shelf option.

Historic District Rules for Door Replacement

If your home sits in Town Center, Upper Montclair, Pine Street, or Watchung Plaza — Montclair's four locally designated landmark districts — a front door replacement that's visible from the street and changes the door's design, scale, or appearance can require a Certificate of Appropriateness from the Historic Preservation Commission before work begins. A repair, or a replacement that exactly matches the existing door's design, generally doesn't trigger this review.

This is the same review process that applies to window replacement on these homes — our window replacement cost guide covers how that process works in more detail, and much of it carries over directly to doors. If you're unsure whether your address falls within a designated district, confirm with Montclair's Building Department before ordering anything custom.

Interior Doors and Whole-House Projects

Interior door replacement is usually a smaller, more straightforward job — $250–$900 per door installed, with cost driven mostly by whether it's hollow-core, solid-core, or a paneled style matching an older home's original trim. Replacing several doors in one visit (a common move during a broader renovation) reduces the per-door labor cost compared to scheduling them one at a time.

Door replacement often comes up alongside a bigger project rather than as a standalone job — a kitchen remodel that relocates a doorway, a basement finishing project adding an egress door, or a full house renovation replacing trim and doors together. See our kitchen remodel cost guide or basement finishing cost guide if doors are one piece of a larger scope.

Finding a Door Installer in Montclair

Ask the installer to inspect the frame, not just measure the opening — frame condition is the biggest source of quote surprises on older homes.
If you're in a historic district, confirm before ordering whether your chosen door needs Commission review.
Verify NJ Home Improvement Contractor (HIC) registration and get a written estimate that separates door cost, frame work (if needed), and labor.
Ask about air sealing and flashing details around the new door — a door that's installed without proper flashing is a common source of water intrusion at the threshold and header down the road.

Frequently Asked Questions

How much does exterior door installation cost in Montclair, NJ?

A standard exterior door installed in Montclair typically runs $900–$3,500, depending on material. Steel entry doors sit at the lower end ($900–$1,800 installed); fiberglass runs $1,500–$2,800; solid wood — often preferred on Montclair's Victorian and Colonial homes for its authentic look — runs $2,500–$5,000+. Doors with sidelights or non-standard sizing (common on older homes) add $500–$2,000.

How much does interior door replacement cost?

Interior doors run $250–$900 installed each, including the door, hinges, and hardware. Hollow-core doors are the least expensive option; solid-core and paneled doors that match the style of an older Montclair home's original woodwork cost more. Replacing several interior doors in the same visit typically reduces the per-door labor cost versus scheduling them separately.

Do I need a permit to replace a door in Montclair?

A like-for-like exterior door swap in the same opening generally doesn't require a permit. Enlarging or moving the opening, replacing a load-bearing header, or work on a home in one of Montclair's designated historic districts can require a permit or a Certificate of Appropriateness — confirm with the Building Department before ordering a non-standard-size door, since custom sizing is common on pre-1960 openings and changes what review applies.

Are there special rules for exterior doors on homes in Montclair's historic districts?

Yes, for homes in the four locally designated landmark districts (Town Center, Upper Montclair, Pine Street, and Watchung Plaza). Alterations visible from the street — including a front door replacement that changes its design, scale, or appearance — can require review and a Certificate of Appropriateness from the Historic Preservation Commission. A repair or exact-match replacement of an existing door generally doesn't trigger this review; a design change does. Confirm your home's district status before ordering a door that doesn't match the original.

Should I replace just the door or the whole frame?

If the existing frame is square, solid, and not rotted, a new door can often be installed in the existing frame — faster and cheaper. On many older Montclair homes, though, the frame itself has settled out of square or has wood rot at the sill, and a new prehung door unit (door plus new frame) installs more reliably and seals better than fighting an out-of-square old frame. An installer should check the frame condition before quoting, not just measure the door opening.
