The short answer
A vinyl replacement window costs about $460 to $1,550 installed in the New York metro, and ten of them run roughly $4,600 to $15,700. What matters most here is the building. A same-size swap in NYC often needs no DOB permit, but landmarks, co-op boards and window guard rules can add steps, while New Jersey treats a same-opening swap as maintenance.
What window replacement costs in New York
Our prices start from national installed costs and apply the New York City construction cost factor of 1.31 from the U.S. Army Corps of Engineers. A window that costs $1,000 to install in an average US market tends to cost about $1,310 here.
| Job | New York (typical range) | US average |
|---|---|---|
| Vinyl window, installed | $460–$1,550 | $350–$1,200 |
| Fiberglass window, installed | $785–$2,600 | $600–$2,000 |
| Wood window, installed | $1,050–$3,950 | $800–$3,000 |
| Aluminum window, installed | $230–$1,300 | $175–$1,000 |
| Composite window, installed | $525–$3,000 | $400–$2,300 |
| 10 vinyl windows, installed | $4,600–$15,700 | $3,500–$12,000 |
| Bay window, vinyl | $1,450–$5,050 | $1,100–$3,850 |
| New trim, per window | $52–$155 | $40–$120 |
Estimates for 2026, including labor and standard parts. New York prices use the metro's construction cost factor of 1.31 (US average = 1.00) from the U.S. Army Corps of Engineers Area Cost Factors. Your quote depends on access, materials and the condition of the home.
The table assumes an insert replacement in a standard opening. Two upgrades are common in this climate, and our calculator prices both. A full-frame replacement adds about 30%, which takes a typical $850 vinyl window to about $1,100. Triple-pane glass adds about 18%, or roughly $1,000 for the same window.
What else moves a New York quote:
- Height and access. Our calculator adds 20% for a third-story window. Ask each installer how the crew will reach upper floors on a walk-up or row house.
- Masonry openings. In brick and brownstone buildings, a window that does not fit the old opening means masonry work, and in NYC that can bring a permit.
- Custom shapes. Arched and oversized windows are made to order and take longer to arrive.
- Lead-safe work. Most homes in the metro were built before 1980, so many jobs follow EPA lead-safe rules.

Frames and glass for New York winters
Central Park's January nights average 27.9°F, and nor'easters bring wind-driven rain and snow from September to April (NWS normals, NWS). Here the window's main job is to keep heat in and wind and water out.
| Frame | Metro installed price per window | Good fit for |
|---|---|---|
| Vinyl | $460 to $1,550 | Detached houses on Long Island, in Westchester and NJ |
| Fiberglass | $785 to $2,600 | Large openings and owners who want a stiff, paintable frame |
| Wood or clad wood | $1,050 to $3,950 | Brownstones, prewar houses, landmark districts |
| Aluminum | $230 to $1,300 | Slim frames; choose a thermally broken model |
| Composite | $525 to $3,000 | Wood look with less upkeep |
Our guides cover each frame in depth: vinyl, fiberglass, wood and aluminum. In a landmark district, the choice of frame may be decided for you, as explained below.
Which ENERGY STAR zone you are in
ENERGY STAR sets window targets by climate zone, and the New York metro straddles two of them.
| Where | IECC zone | ENERGY STAR zone | Window U-factor | SHGC |
|---|---|---|---|---|
| Five boroughs, Nassau, Suffolk, Westchester | 4A | North-Central | 0.25 or lower | 0.40 or lower |
| Essex, Hudson, Union counties (Newark, Jersey City) | 4A | North-Central | 0.25 or lower | 0.40 or lower |
| Bergen, Passaic, Morris, Somerset counties | 5A | Northern | 0.22 or lower | 0.17 or higher |
Sources: 2021 IECC county table, NJ Bulletin 22-1, ENERGY STAR Version 7.0.
In the Northern zone, the SHGC figure is a floor rather than a ceiling, so a low-gain glass made for southern climates can fail it. A window certified for North-Central may not qualify in Bergen County. Ask for the certification for your county. Our energy-efficient windows guide explains the label.
What the energy codes require
The 2025 NYC Energy Conservation Code allows a vertical window U-factor of 0.27 and an SHGC of 0.40 in climate zone 4, and it applies to complete energy filings made on or after March 30, 2026 (NYC DOB, DOB FAQ). The 2025 state energy code, used outside the city, lists the same 0.27 for zone 4 (NYS Department of State). The city's permit rule also says a permit exemption does not excuse work from the energy code, so the rating applies even when no permit is filed (1 RCNY 101-14).
In New Jersey, a building undergoing alteration has to meet the state's Rehabilitation Subcode rather than the full energy subcode for new buildings (NJ Bulletin 22-1). The ENERGY STAR rating for your zone is the simplest target there.
The federal tax credit for energy-efficient windows does not apply to windows placed in service after December 31, 2025 (IRS).
Do you need a permit to replace windows?
It depends on the state and the building.
| Where | Same-size replacement | What can add a step |
|---|---|---|
| New York City | Often no DOB permit, if all four conditions are met | Landmark or historic district, co-op or condo board, fire-rated windows, masonry or lintel work |
| Long Island and Westchester | Ask the town, village or city building department | Coastal windborne debris zone |
| New Jersey | No permit for the same opening without changing framing | Changing the opening, framing or egress |
New York City
The Department of Buildings rule on minor work lists the replacement of existing windows, including balcony doors, as work that needs no permit when four things are true: the window is not on the lot line, the masonry opening does not change, light and ventilation are not reduced, and the operable area stays the same (1 RCNY 101-14). Replacing required fire-rated windows does need a permit. So does removing and replacing steel lintels above windows beyond a small area.
The same rule says the exemption does not cancel filings with other agencies. The Landmarks Preservation Commission oversees more than 38,000 properties, most in 157 historic districts. Replacing windows on a landmarked building takes a Permit for Minor Work, which has no fee, while fixing broken glass needs no LPC review (NYC Business). Apply before you order, since the permit covers changes to the building's protected features and the new windows have to match what LPC approves.
In a co-op or condo, when a unit owner files a DOB application, it must include a statement that the board authorized it (DOB OPPN 17/87). Ask the managing agent for the building's own window rules and alteration agreement before you collect quotes.
Long Island and Westchester
Outside the city, the state's Uniform Code applies and each town, village or city runs its own building department (NYS Department of State). State rules list the only kinds of work a town may exempt from permits (19 NYCRR 1203.3), and practice varies by town, so call your building department before you sign.
On the coast, ask one more question. The state lets each town mark itself as a windborne debris zone if it lies within a mile of the coast where design wind speeds reach 130 mph, or anywhere they reach 140 mph. In those places, new glazed openings must resist windborne debris with impact glass or shutters (NYS DOS bulletin). Our impact windows guide covers the product.
New Jersey
New Jersey's Uniform Construction Code treats window and door replacement in the same opening, without changing the framing, as ordinary maintenance: no permit and no inspection (N.J.A.C. 5:23-2.7). Changing the size of the opening or the egress from a room takes a permit from the municipal construction official.
Window guards, egress and safety
Window guards in NYC apartments
In a building with three or more apartments, the owner must install approved window guards on every window in any apartment where a child 10 or younger lives, including first-floor and bathroom windows and windows onto a balcony or terrace. Windows that open onto a fire escape are excluded (NYC Health). If you own a multifamily building or a unit in one, plan for the guards when you order new windows, since they mount to the window opening.
Bedroom escape windows
The state residential code lets a replacement window skip the minimum opening and sill height rules for bedroom escape windows only if the new window is the manufacturer's largest standard size that fits the existing opening, in the same style or one that opens wider (2020 Residential Code of NYS, R310.2.5). Swapping a double-hung for a smaller fixed window in a bedroom does not qualify.
Lead-safe work in older buildings
Most of the metro's housing predates the 1978 lead paint ban. In the Census Bureau's 2024 survey, 77.9% of New York City homes were built before 1980, along with 84.1% in Nassau County and 71.9% in Bergen County. Nearly half of Brooklyn's homes were built before 1940 (Census Reporter, ACS 2024).
Under the EPA's Renovation, Repair and Painting rule, window replacement in a pre-1978 home always counts as covered work, so a certified firm has to do it with lead-safe practices (EPA). New York City adds Local Law 1 of 2004 for rental buildings with three or more units built before 1960 where a young child lives (NYC HPD). NYC's home improvement license also requires EPA lead certification or a signed affirmation.
How to check a window installer before you hire
New York and New Jersey have no state window license. The license that matters is the home improvement license or registration for where you live.
| Where you live | What the installer needs | Where to check |
|---|---|---|
| Five boroughs | NYC DCWP Home Improvement Contractor license for jobs over $200 | DCWP license lookup or 311 |
| Nassau County | County home improvement license | Nassau Consumer Affairs |
| Suffolk County | County home improvement license | Suffolk Consumer Affairs, (631) 853-4600 |
| Westchester County | County home improvement license | Westchester Consumer Protection, (914) 995-2155 |
| New Jersey | HIC registration, which covers windows | NJ Consumer Affairs, 1-800-242-5846 |

Before you sign:
- Look up the license or registration number and check that the business name matches.
- Get the window line, frame, U-factor, SHGC and ENERGY STAR zone in writing, plus insert or full-frame.
- For a pre-1978 home, ask for the firm's EPA lead-safe certification.
- Get a written contract for any job over $500. Both states give you three business days to cancel. In New York State, a contractor must put deposits in a trust account at a New York bank within five business days or give you a bond, and progress payments must match the work done.
- In New Jersey, be wary of anyone asking for more than one third of the price up front, and ask for proof of the required $500,000 liability insurance.
Every installer in the GOLDGCP network passes six-step vetting: license verification, an insurance check, a background and business check, a portfolio review, client reference calls, and onboarding with a quality score. You pay in milestones, each one after you approve that stage. Read more about how milestone payments work.

Frequently asked questions
How much does window replacement cost in NYC?
A vinyl replacement window costs about $460 to $1,550 installed in the New York metro, fiberglass $785 to $2,600 and wood $1,050 to $3,950. Ten vinyl windows run about $4,600 to $15,700. Full-frame installation adds about 30% and triple-pane glass about 18%.
Do I need a permit to replace windows in NYC?
Often not. DOB exempts replacing existing windows when the window is not on the lot line, the masonry opening stays the same, light and ventilation are not reduced, and the operable area does not change. Fire-rated windows need a permit, and landmarked buildings need an LPC Permit for Minor Work.
Can I replace windows in a landmarked building in New York?
Yes, with LPC approval first. Replacing windows on a landmarked building or in one of the city's 157 historic districts takes a Permit for Minor Work, which has no fee. Apply and get the permit before you order the windows.
What U-factor do new windows need in New York?
The 2025 NYC Energy Conservation Code and the 2025 state code list a maximum U-factor of 0.27 for windows in climate zone 4, which covers the five boroughs, Long Island and Westchester. ENERGY STAR's North-Central zone asks for 0.25 or lower.
Do I need a permit to replace windows in New Jersey?
Not for a replacement in the same opening without changing the framing. New Jersey's Uniform Construction Code treats it as ordinary maintenance with no permit or inspection. Enlarging the opening or changing a bedroom's escape window needs a permit from your town's construction official.
Who has to install window guards in New York City?
The owner of a building with three or more apartments must install approved window guards on the windows of any apartment where a child 10 or younger lives, including first-floor and bathroom windows. Windows that open onto a fire escape are excluded.
Do window installers need a license on Long Island?
Yes. Nassau County and Suffolk County each require a county home improvement license, so ask for the license number and check it with the county. Westchester has its own county license, NYC uses a DCWP license, and New Jersey requires HIC registration with the Division of Consumer Affairs.
How we calculate these prices
GOLDGCP starts from national price ranges for each job, taken from published 2026 cost guides and checked against local price guides where they exist. To get a local price, we multiply the national range by the construction cost factor for the metro from the U.S. Army Corps of Engineers Area Cost Factors (US average = 1.00). For ZIP codes outside the 50 largest metros, the calculator uses the state's price level from the Bureau of Economic Analysis Regional Price Parities. Ranges include labor and standard materials but not unusual site conditions, so a written quote after an inspection is always the final price.
