Window companies love a number they can't be held to. "Starting at $299 installed" is one. The $2,400-a-window quote after a three-hour pitch is another. Here's what replacement windows actually cost across New Jersey in 2026 — per window and per house — and the seven things that move your number.
2026 New Jersey price brackets
Those are fixed-price ranges for a licensed, insured contractor doing it right: sill pan, flashing membrane, foam, interior stops and exterior capping. A handyman number will be lower. The window-chain number will be higher, and a good chunk of it is the pitch.
| Window or door | Typical installed price |
|---|---|
| Vinyl double-hung, insert (pocket) replacement | $650 – $1,400 each |
| Vinyl double-hung, full-frame replacement | $1,000 – $1,900 each |
| Fiberglass or composite window | $1,200 – $2,500+ each |
| Wood-clad window (the look for older homes) | $1,500 – $3,200+ each |
| Bay or bow window | $4,000 – $10,000 |
| Basement egress window with well, drain and permit | $4,500 – $9,500 |
| Whole house, 12–15 windows, vinyl to fiberglass | $9K – $30K |
| Entry door, fiberglass or steel, pre-hung | $2,200 – $6,500 |
| Sliding or French patio door | $2,500 – $7,000 |
Where the money goes on a $1,100 window
Use these to read a quote. If the window is 80% of the number, the flashing and trim aren't in it.
- The unit itself: 45–55%. Frame material, glass package and size decide this line.
- Labor: 30–40%. Pull the old sash and frame, flash the opening, set it plumb and square, foam it, trim it.
- Exterior capping and interior trim: 5–10%. Aluminum coil bent on site to wrap the old wood, new stops or casing inside.
- Flashing tape, sill pan, foam, caulk, disposal: the rest.
The 7 things that move the price
An insert goes inside your existing frame: less labor, less mess, a bit less glass. A full-frame replacement takes everything out to the rough opening so we can check the framing, flash the hole and set the new unit. It costs $300–$600 more per window and it's the right call when the sill is rotten, the frame is out of square, or you want a bigger view.
Vinyl is the value pick and lasts 20–30 years. Fiberglass costs about 40% more, barely moves with heat and cold, and can be painted. Wood-clad — real wood inside, a metal or fiberglass skin outside — is the look for a 1920s colonial in Ridgewood or Montclair, and it's priced like it.
Double-pane low-E with argon is standard and right for most houses. Triple-pane adds $150–$300 a window and earns it on a busy road. Laminated glass cuts noise more than a third pane does. And the code requires tempered glass next to a tub, a door or a floor — a line item, not an upsell.
A standard double-hung is cheap to make. A six-foot picture window, an arch over the front door or a trapezoid in a split-level's gable is not. Odd shapes can double the unit price and add weeks to the lead time.
Setting up, protecting the floors and running a dumpster costs about the same for three windows as for fifteen. Do the whole house and the per-window price drops. Do one wall a year and you pay for five setups.
Houses from the 50s and 60s across Bergen and Passaic often still have the original wood windows with aluminum storms, and the sills under them — especially on the weather side — are often soft. We probe every sill on the free visit and price rot repair by the opening, so it's in your fixed number, not on a change order.
Ladder work is slower. A three-story colonial or a window over a porch roof takes staging, and brick or stucco needs different trim than clapboard. Not dramatic money, but real, and it belongs on the quote.
Why the big window brands quote $1,800 for a $900 window
The national window companies sell in your living room. A commissioned rep spends three hours on the demonstration, shows you a "list price," then knocks 40% off if you sign tonight. The next day his manager calls with a lower number. None of that changes what the window costs to make or install. It's a pitch, and you're paying for it.
We don't have salesmen. The foreman who measures your openings writes the itemized price on the spot, and it's the same number next month. No franchise fees, no commissioned salesmen and no rented subcontractors is how we land typically 15–30% under national-brand quotes for the same or better spec. Bring us any written quote and we'll match the scope line by line.
Do you need a permit in New Jersey?
Replacing a window with the same size unit in a one- or two-family home is usually ordinary maintenance under the state construction code, so no permit. Change the opening size, add a structural header, or cut the foundation for an egress window and you need one, with an inspection. We check your town before we order; if a permit is required, it's in the price and in our name.
Timeline, and the best time of year
We measure every opening twice on the free visit. Custom units take three to six weeks to arrive. The install is one or two days for most houses, and every opening is opened, flashed, set, foamed and trimmed the same day — you never sleep with a hole in the wall.
Winter installs are fine — each opening is open for under an hour, one room at a time with the door closed. Spring and fall are the busy seasons, so for a summer install, order in April.

Questions people ask next
How much does one replacement window cost in NJ?
A vinyl insert installed by a licensed contractor runs about $650 to $1,400 in 2026. Full-frame, fiberglass or wood-clad pushes that to $1,200 to $3,200. One window costs more per unit than a whole house, because the setup is the same either way.
Is it cheaper to replace all the windows at once?
Per window, yes — usually 10–20% less than doing them in batches. If the budget only covers half, do the weather side and the worst sills first. We'll price the rest so you know the number when you're ready.
Are triple-pane windows worth it in New Jersey?
On a busy road or near a highway, yes — the noise drop is the part you'll notice. For energy alone, double-pane low-E with argon gets most of the gain for less money. We'll price both so you can decide window by window.
Will new windows lower my heating bill?
Some, depending on what you have now. Going from single-pane wood with leaky storms to double-pane is a real drop in drafts and on the bill. Going from 15-year-old vinyl to new vinyl is about comfort more than savings. Nobody's windows pay for themselves in five years, whatever the rep says.
