New Construction Windows in Boise, ID
Idaho's capital, from the historic North End to the Foothills
New-construction windows are designed to be installed into an open, unfinished wall — they have a nailing fin that fastens directly to the sheathing and integrates with the weather barrier, which makes them the correct choice for new homes, additions, and any project where the wall is opened to the framing. It's a different unit and a different install from a replacement window that slots into an existing frame.
We install new-construction windows on additions, rebuilds, and openings taken back to the studs, working from the framing out — setting the unit by its fin, integrating it with the flashing and weather-resistive barrier, and air-sealing and insulating before the wall is closed up. Because we're starting from an open wall, the result is a fully integrated, weather-tight opening rather than a unit wedged into an old frame.
Starting from the framing is the advantage. The flashing laps correctly over the fin and into the weather barrier, the rough opening can be sized right, and the air-sealing and insulation are done before drywall — all the things that are compromised or impossible when you're working around existing finishes. Done in sequence, it's the highest-performing way to install a window.
These windows belong in new walls, not as a swap into an existing finished opening — for that, a replacement (insert) window is the right product. We'll confirm which your project actually needs so the unit, the install, and the weatherproofing match the situation.

Our process
How new construction windows works in Boise
- 01
Coordinate with framing
We confirm rough-opening sizes against the window schedule and coordinate timing so the openings are framed correctly and ready for the units.
- 02
Window & glass selection
We match frame material, operating style, and a low-E glass package to each elevation's U-factor and SHGC needs before ordering.
- 03
Set by the fin & flash
Each unit is set level, square, and plumb and fastened by its nailing fin, then flashed so the laps shed water out over the fin and into the weather barrier.
- 04
Integrate barrier, air-seal & insulate
We integrate the weather-resistive barrier over the flashing and air-seal and insulate the rough opening before the wall is closed — the sequence a replacement can't match.
- 05
Trim, finish & walkthrough
Once the wall is finished, we set interior and exterior trim, test operation, and walk the completed openings with you.
Every Boise job includes pulling any permit Ada County requires and a full clean-up — we leave your home tight, weather-sealed, and looking sharp.
Working in Boise
Idaho's capital, from the historic North End to the Foothills
Boise climbs from the Boise River and its Greenbelt up into the Foothills, layering century-old North End and East End homes over mid-century Bench ranches and newer hillside subdivisions like Harris Ranch. That spread of building eras means the exterior conditions vary block by block — original old-growth wood lap and cedar shakes downtown, painted hardboard and aluminum on the Bench, and 1990s–2000s vinyl on the foothill edges that is now reaching replacement age.
Older Boise homes often hide failing siding and single-pane wood or aluminum windows behind charming facades, while south- and west-facing foothill elevations take a beating from intense afternoon sun. Freeze-thaw swings and wind off the hills make proper flashing, house wrap, and a weather-tight install matter as much as the material itself.

Will you clean up after new construction windows in Boise?
Always. Every Boise job ends with a full clean-up — we haul away the old materials and packaging and leave your Ada County home tidy and protected.
What's the difference between new-construction and replacement windows?
A new-construction window has a nailing fin that fastens to the sheathing and integrates with the weather barrier — it's for open, unfinished walls. A replacement (insert) window slots into an existing frame without disturbing the surrounding finishes. They're different units for different situations, and we'll confirm which your project needs.
When do I need new-construction windows?
On new homes, additions, and any opening taken back to the framing — anywhere the wall is open to the studs. If you're swapping a window into an existing finished opening without opening the wall, a replacement window is the right product instead.
Why is the install better from an open wall?
Because the flashing can lap correctly over the fin and into the weather barrier, the rough opening can be sized right, and the air-sealing and insulation are done before drywall — all the steps that are compromised or impossible when working around existing finishes. Done in sequence, it's the highest-performing way to install a window.
