New Construction Windows in Boise, ID
Idaho's capital, from the historic North End to the Foothills
Boise's new-build pipeline runs from infill teardown-rebuilds in the North End and East End to whole subdivisions climbing the Foothills around Harris Ranch and into Southeast Boise, and every framed opening needs windows set before close-up. Iron Crest Exteriors works new construction for builders and GCs the way the open wall allows — nail-fin units set level and square to the plan-spec schedule, flashed so the laps shed water out over the fin and into the weather barrier, then air-sealed and insulated before drywall. On steep foothill lots and tight downtown infill alike, our crews schedule around framing so openings are ready for the energy-code inspection. That sequence carries a Boise home through freeze-thaw winters without air leaking around the frame.

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.

New Construction Windows in Boise — FAQs
How do you handle the varied window schedules across Boise's foothill subdivisions versus North End infill?
We work off the plans for each job rather than a one-size approach. A Foothills production home and a North End custom infill carry different schedules — grid patterns, sizes, U-factor and SHGC targets by elevation — so we confirm rough-opening dimensions against the schedule before the units arrive, install to whatever the approved plans and architectural review call for, and coordinate timing with your framing crew so the openings stay on the build calendar through inspection.
Do you offer new construction windows throughout Boise?

Absolutely. Beyond Boise, we cover Garden City, Eagle, Meridian, Kuna and the rest of the Treasure Valley — anywhere out toward the Boise River is comfortably within our range.
What's the site like after the work is done in Boise?
Spotless. We finish every Boise project by clearing out old materials and debris, so your Ada County property is left clean 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.
