Bay & Bow Windows in Boise, ID
Idaho's capital, from the historic North End to the Foothills
A bay or bow window is one of the more transformative upgrades for a Boise living or dining room — an angled bay pairs a fixed center with two canted side units, while a bow curves several equal units into a softer projection, both cantilevering out to pull daylight from three directions and add a shelf or window seat inside. The older homes of the North End and East End, with their formal front rooms, are natural candidates, and foothill custom builds use them to frame a Table Rock or valley view. Because the assembly projects past the wall, Iron Crest Exteriors treats the insulated seat and head board, structural support, and flashing as the heart of the job. Done right, it turns a flat North End wall into the room's signature feature.

Our process
How bay & bow windows works in Boise
- 01
On-site assessment & design
We evaluate the wall, plan the bay or bow configuration and projection, and confirm structural support needs before quoting a firm price.
- 02
Glass & frame selection
We match U-factor and SHGC to the elevation, choose operable side units for ventilation, and explain vinyl, fiberglass, and composite frame options.
- 03
Remove old unit & inspect
The old window comes out and we inspect and prepare the opening and surrounding wall, addressing rot or moisture before building out the projection.
- 04
Support, set, flash & insulate
We provide proper structural support, set the assembly level and square, then flash, insulate, and seal the unit — including the projecting roof or head and seat — so it's weather-tight and warm.
- 05
Trim, finish & walkthrough
Interior and exterior trim and the seat or shelf are finished, joints sealed, operable units tested, and we walk the completed projection 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.

Bay & Bow Windows in Boise — FAQs
Will adding a bay window to my historic North End home keep its period character?
It can, when the proportions and trim are planned to suit the house. Many Boise North End and East End homes from the 1900s–1930s had bay projections originally or read naturally with one, so we size the bay or bow to the room's scale, configure divided-light or simpler sashes to match the era, and detail the interior seat and exterior trim to fit the facade rather than fight it. If your block falls under any historic or design guidance, we'll work the configuration to suit it before anything is built.

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 a bay and a bow window?
A bay typically combines a large fixed center with two angled side units for a sharper, more angular projection, while a bow uses a curve of several equal-sized units for a softer, rounded one. We'll show you both against your wall and room proportions so you can choose the look you want.
Do bay and bow windows open?
The side units usually do — they're commonly operable casements or double-hungs — so you get ventilation along with the view, while a large center unit may be fixed for maximum glass. We configure the operable units to suit the room.
