Stop paying to heat
the outdoors.
Replacement windows that cut the drafts, quiet the house, and hold your heat through a New Hampshire winter, installed and sealed right.
Old windows are one of the leakiest parts of a house. Single panes and failed seals let heat pour out and cold air in, and no amount of turning up the thermostat fixes a window that has quit insulating. Fogging between the glass is the seal telling you it is done.
We replace one window or every window, sealed and trimmed so the install is as tight as the glass. Most replacement windows run about $500 to $1,200 each installed depending on size and type. You get a firm number at the free estimate.
When it is time
Windows rarely fail dramatically. They just get draftier, harder to open, and more expensive to live with each winter. Here is what usually means it is worth replacing them.
| What you notice | What it means |
|---|---|
| Fog or moisture between panes | The insulating seal has failed |
| Drafts near the window | Air is leaking around or through it |
| Hard to open, close, or lock | Worn or swollen frames and hardware |
| Rising heating bills | You are heating air that leaves through the glass |
Glass and frames
For our climate, double-pane low-E glass in a well-insulated frame is the baseline. It reflects heat back into the room in winter and keeps it out in summer. Triple-pane is the upgrade for the coldest, noisiest, or most exposed spots.
| Option | Best for | Relative cost |
|---|---|---|
| Double-pane, low-E | Most homes, the New England baseline | $$ |
| Triple-pane | Coldest, noisiest, most exposed rooms | $$$ |
| Vinyl frames | Low maintenance, good insulation, most homes | $$ |
How the job goes
- Free on-site measure. We measure each opening, check the condition of the frames and trim, and give you a written quote.
- Old units out. The old windows come out and we look at the surrounding wood before the new ones go in.
- Set, flashed, insulated. New windows are set level, flashed against water, and insulated around the frame so there is no draft path.
- Trimmed and sealed. We finish the exterior trim and seal it, and clean up the old windows and debris.
What windows cost, and what moves the price.
| Scope | Typical range |
|---|---|
| Per window, installed | about $500–$1,200 |
| Larger, specialty, or triple-pane | more, quoted on site |
| Whole-house project | scales with the number and size of windows |
| Factor | Why it matters |
|---|---|
| Number of windows | The biggest driver of a whole-house project. |
| Size & style | Large, bay, or specialty shapes cost more than standard units. |
| Glass package | Triple-pane and premium coatings add cost. |
| Frame material | Vinyl, wood, and composite frames price differently. |
| Rot or trim repair | Any bad wood around the opening is fixed before the new window goes in. |

Window questions.
When is it worth replacing my windows?+
When you feel drafts, see condensation between the panes, struggle to open or lock them, or your heating bills keep climbing. Fogging between the glass means the seal has failed and the window is no longer insulating the way it should.
How much do replacement windows cost in New Hampshire?+
Most replacement windows run about $500 to $1,200 per window installed, depending on size, frame material, and glass. A whole-house project scales from there. These are typical ranges, not a quote; we price your specific windows on site.
Will new windows lower my heating bill?+
Modern double-pane, low-E windows insulate far better than old single-pane or failed units, so they cut drafts and help hold heat through a New Hampshire winter. How much you save depends on what you have now and how leaky it is.
Do you replace one window or the whole house?+
Both. We will replace a single failed window or do every window in the house. If only a few are bad we will tell you that rather than sell you a full project you do not need.
Do you seal and trim around the new windows?+
Yes. A window is only as good as its install. We flash, insulate, and seal around each unit and finish the exterior trim so water and cold air stay out.
