Egress Windows in Boise, ID
Idaho's capital, from the historic North End to the Foothills
Boise basements run the full spread of the city's eras — daylight and walkout lower levels under newer Foothills and Harris Ranch homes, and tight, low-headroom cellars beneath North End and Bench houses where one small original window is the only opening below grade. Finishing those levels into bedrooms, guest suites, or rentals is among the most common ways Boise homeowners add livable square footage, and code requires any sleeping room to have a compliant egress opening: minimum clear width, height, and total area, with a sill an occupant can reach. Where the existing window falls short, that means cutting and reinforcing the foundation wall and building a drained well. Iron Crest Exteriors handles all of it, so a Boise basement bedroom finally counts as one.

Our process
How egress windows works in Boise
- 01
Assessment & code check
We evaluate the opening, the foundation, and the grade, and confirm the exact clear-opening width, height, area, and sill-height figures the code requires before quoting.
- 02
Plan cut & reinforcement
Where the opening must be enlarged in a foundation wall, we plan the cut and any reinforcement so the wall stays sound and the opening meets the egress dimensions.
- 03
Cut, set & build the well
We make the opening, set the egress unit level and square, and build the window well to the required size with a ladder or step where the depth calls for one.
- 04
Drainage, flash & insulate
We install proper well drainage so it won't fill with water or snowmelt, then flash, air-seal, and insulate the unit so it's weather-tight and warm.
- 05
Finish, inspect & walkthrough
Trim and grading around the well are finished, the work is coordinated for inspection against the egress code, and we walk the completed opening 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.

Egress Windows in Boise — FAQs
We're finishing a basement bedroom in our North End home — does it legally need an egress window?
Yes. Building code requires every room used for sleeping — including a finished basement bedroom — to have a compliant emergency escape opening, and that applies regardless of the home's age. Many North End and Bench basements only have a small original window that falls short of the minimum clear width, height, and area, so the work usually means enlarging the opening, cutting and reinforcing the foundation wall, and building a window well. We coordinate the permit and inspection, because it's both structural and life-safety work.
Is egress windows available across Boise?
It is — every neighborhood in Boise and the surrounding Ada County, including the North End, the East End, and the Bench. Ask us for a free on-site estimate.
Do you work outside Boise, too?
We do — along with Boise, we regularly handle egress windows in nearby Garden City, Eagle, Meridian, Kuna and across the wider Treasure Valley. If you're near the Boise River, you're well inside our service area.
Will you clean up after egress 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.
Do I legally need an egress window?
Any room used as a sleeping room — including a finished basement bedroom — is required by building code to have a compliant egress opening for emergency escape and rescue. Without one, the space can't legally be called or used as a bedroom, which also affects appraisal and resale.
Can you cut an egress opening into my foundation?
Yes. Where an existing basement opening is too small, we plan and make the cut in the foundation wall with any reinforcement the structure needs, then build the window well. It requires a permit and inspection, which we coordinate, because it's both structural and life-safety work.
