The Window Source How Much Do Replacement Windows Cost in New Hampshire? (2026 Guide) New Hampshire, Massachusetts, and Maine
The short answer: our replacement windows run $545 to $683 per window, installed. That’s the real, in-writing price for a white double hung with basic installation included — not a teaser number that doubles on install day. Here’s the full breakdown, because we think you should be able to see the numbers before anyone sits in your living room.
Installed Prices by Model (2026)
| Model | Installed from | Highlights |
|---|---|---|
| Harvey Slimline | $545 | Sleek narrow frame, built by Harvey in New England |
| Harvey Classic — our best seller | $617 | .24 U-value, fusion-welded, double-strength glass |
| Gentek Series 3000 | $587 | Foam insulation, double-strength glass |
| Gentek Series 9000 | $683 | Triple pane, Energy Star Most Efficient, tax credit eligible |
Every model includes a transferable Lifetime Warranty and professional installation by our own crew. Prices are for white double hungs with basic installation; optional grids, colors, and wood grains add cost.
What Does a Whole House Cost?
Most New England homes have 8–15 windows. At our prices, a typical 10-window home runs roughly $5,450 to $6,830 depending on the model — and orders of 10 or more windows currently take $250 off with the 250 Sale. Compare that with the $1,000-and-up per-window quotes national brands are known for, and you can see why our tagline is “Best Window. Best Price. Guaranteed.”
What Changes the Price?
Size and shape. Standard double hung sizes anchor the prices above; oversized units, bays, bows, and specialty shapes are custom-quoted. Options. Colonial grids, exterior colors, and interior wood grains add to the base price. Glass package. Stepping up to triple pane (the Series 9000) costs more up front and saves the most on heating. The condition of your openings. If we find rot or damage during the measure, we tell you in the written quote — our installers are known for replacing rotten areas rather than simply covering them.
Why We Quote in Writing, in Your Home
Phone estimates are guesses — and in this industry, the guess often doubles once someone finally measures. We do it once, properly: measure every opening, quote the exact price in writing, and leave you to decide. No pressure in your living room, no expiring “tonight only” discounts.
Can I Finance New Windows?
Yes — financing through Synchrony runs as low as 0% for 18 months*, which puts a house full of windows around $87/month*. Since new windows start saving on your utility bills immediately, many customers finance the install and let the energy savings help carry the payment. *Rates and terms dependent on qualifying credit.
