Double-Hung Windows in Boise, ID
Idaho's capital, from the historic North End to the Foothills
The double-hung is the window Boise's older streets were built around — the North End and East End are full of 1900s–1930s homes whose original wood double-hungs have swollen, painted shut, or lost their sash cords decades ago. Iron Crest Exteriors replaces them with modern double-hungs whose sashes both operate and tilt in for cleaning, in vinyl or fiberglass frames and grid patterns that keep the proportions these historic facades depend on. With proper flashing and air sealing on century-old framing, the new units finally open and close while sealing out the drafts that roll off the Foothills.

Our process
How double-hung windows works in Boise
- 01
On-site measure & assessment
We measure every opening, check the existing frame and surrounding wall for rot or water damage, and confirm frame material and glass package before quoting a firm price.
- 02
Glass & frame selection
We match U-factor and SHGC to each elevation and walk you through vinyl, fiberglass, and composite frames so you understand the trade-offs before anything is ordered.
- 03
Remove old units & inspect
Old sashes and frames come out and we inspect the rough opening, addressing any rot or moisture damage we find before the new unit goes in.
- 04
Set, flash & insulate
Each window is set level and square, flashed and air-sealed to the weather barrier, and the gaps are insulated so the rated performance is actually achieved.
- 05
Trim, seal & walkthrough
Interior and exterior trim is finished, joints are sealed, we test every sash for smooth operation, and we walk the job with you before closeout.
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.

Do you work outside Boise, too?

Will you clean up after double-hung 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 double-hung and single-hung?
In a double-hung both sashes operate and tilt in for cleaning; in a single-hung only the bottom sash moves. Double-hung costs a bit more but gives you top-down ventilation and far easier cleaning on upper floors, which is why most of our valley customers choose it.
Will new double-hung windows stop my drafts?
A properly installed, well-flashed double-hung with a low U-factor seals far tighter than old single-pane or worn aluminum windows. Most drafts we find trace to failed seals and poor air-sealing around the old frame, and correct installation is what fixes that — not just the new unit.
What does U-factor and SHGC mean for my home?
U-factor measures how well the window resists heat loss — lower is better for our cold winters. SHGC measures how much solar heat the glass lets in — a lower SHGC on south- and west-facing walls keeps summer afternoons cooler. We match both to each elevation.
