Window Replacement & Restoration in Sunset / 30th Street
Original 1925 double-hung restoration with weatherstripping and storm windows, divided-light wood-clad replacement matching Craftsman grille patterns, premium dual-pane on post-war Sunset Park.
Window work in Sunset divides into two materially different programs. North of West State on the bungalow streets, the original 1925 wood double-hung windows with their divided-light upper sashes and chain-and-weight operating systems are often restorable — failed glazing putty, sticking sashes, painted-shut weights, and worn weatherstripping are all addressable through restoration at $850-$2,500 per window, often paired with period-appropriate aluminum or wood storm window addition for thermal performance ($350-$850 per opening). Where original windows are beyond restoration, replacement matching the original Craftsman divided-light grille pattern is the standard — Marvin Signature, Pella Architect Reserve, Sierra Pacific H3 in simulated divided light wood with painted finishes and divided-light grilles. South of West State on Sunset Park and Veterans Park, original 1945-1965 wood double-hungs (single-pane) are typically beyond restoration after 60-80 years and warrant premium dual-pane replacement. Lower Bench transition splits often have original aluminum sliders that need replacement. Iron Crest works the entire Sunset corridor — restoration where viable, premium replacement where justified — and runs EPA RRP universal across every project.
Window strategy in Sunset depends on era, original window condition, and whether period authenticity matters to the owner.
1920s–1939 Craftsman bungalow wood double-hungs (27th–33rd north of West State)
Original wood double-hung single-pane with divided-light upper sashes (typically 6-over-1 or 4-over-1 grille patterns). Chain-and-weight operating systems. Substantial period character — divided light, painted wood casings, sometimes leaded or beveled glass in transom or sidelights. Restoration strongly preferred. Period-appropriate replacement (simulated divided light wood-clad matching original profile) where restoration isn't viable. Storm window addition ($350-$850 per opening) for thermal performance.
1940s–1959 Sunset Park and Veterans Park wood double-hungs
Wood double-hung single-pane with simpler post-war grille patterns (typically 1-over-1 or 6-over-6). Less elaborate divided light. Restoration sometimes viable but often replacement is more cost-effective. Premium dual-pane replacement standard.
1960s–1985 Lower Bench transition aluminum sliders and wood double-hungs
Original aluminum slider windows or first-generation dual-pane wood-clad. Often seal failures with visible internal condensation. Replacement scope common with premium dual-pane low-E argon-filled.
2010+ townhomes and 30th Street infill
Modern dual-pane or triple-pane from original construction. Replacement less common.
Five recurring window project shapes account for nearly every Sunset quote.
1. The 1925 Bungalow Whole-House Restoration
Comprehensive restoration of original wood double-hung windows on a Sunset Craftsman bungalow. Reglazing failed putty (linseed oil-based glazing compound), chain-and-weight repair or sash chain replacement, weatherstripping installation (bronze or felt-lined for period authenticity), sash work to address sticking or painted-shut conditions, hardware refurbishment. Sometimes includes storm window addition for thermal performance. Preserves period character at substantially lower cost than replacement.
Target homes: Pre-1940 original Sunset Craftsman bungalows on 27th–33rd north of West State.
2. The Bungalow Restoration with Storm Window Addition
Whole-house restoration of original wood double-hungs plus addition of period-appropriate storm windows (factory-finished aluminum in colors matching original — typically white or bronze) for thermal performance enhancement. Often achieves comparable thermal performance to replacement at lower cost while preserving original windows.
Target homes: Sunset bungalows wanting balance of preservation and energy performance.
3. The Bungalow HPC-Style Period-Matched Replacement
Where restoration isn't viable on a 1925 bungalow, full replacement with simulated divided light wood or aluminum-clad wood matching original profile, divided light pattern, and aesthetic. Marvin Signature or Pella Architect Reserve typical specification. Triple-pane low-E argon-filled glazing. Painted finishes matching original. Note: Sunset is not within a Boise Historic District, so HPC review doesn't apply — but Iron Crest applies HPC-style sensitivity for resale value preservation.
Target homes: Pre-1940 original Sunset bungalows where original windows are beyond restoration.
4. The Whole-House Premium Replacement (Post-War Sunset)
Full window replacement on a 1945–1980 Sunset Park, Veterans Park, or Lower Bench home. Premium brand specification (Marvin, Pella, Andersen, Sierra Pacific). Triple-pane low-E argon-filled glazing typical. Aluminum-clad exterior with painted or stained interior. Standard aesthetic matching home design.
Target homes: Pre-1985 Sunset homes with end-of-life original windows.
5. The Spot Replacement
Specific window replacement(s) — typically 3-8 windows that have failed seals, structural damage, or are beyond restoration. HPC-style period matching for bungalow scope; standard premium replacement for post-war.
Target homes: Sunset homes with isolated window issues.
The Sunset / 30th Street spans roughly two square miles with distinct sub-neighborhoods, each with its own remodeling personality.
30th Street commercial / Whitewater Park
The recently revitalized commercial-residential corridor along 30th Street between West State Street and the Boise River. Anchored by the Boise Whitewater Park (kayaking and surfing wave), Esther Simplot Park, the Greenbelt, and the 30th Street commercial district (Push & Pour, Local Cellular, Steelhead, breweries). Mix of original 1920s-40s bungalows undergoing gentrification, mid-century infill, and new 2010s-2020s townhomes and small apartment buildings. Walkable urban character. Home values $475K-$985K (single-family) with strong appreciation curve.
Sunset Park / West State Street
The neighborhood centered on Sunset Park along West State Street and surrounding residential streets. Predominantly 1925-1955 single-family homes (1,200-1,800 sq ft) on 50' × 110' to 60' × 130' lots. Quieter than 30th Street corridor, family-focused community character with mature street trees. Home values $475K-$785K.
Veterans Park
The neighborhood surrounding Veterans Memorial Park along Veterans Memorial Parkway, west of Sunset Park. Mix of 1940s-60s post-war housing and 1970s-80s infill. Lots typically 60' × 120'. Strong family-focused community with park access and Greenbelt proximity. Home values $475K-$785K.
Lower Bench transition (south side)
The southern edge of Sunset where the neighborhood transitions toward the geological Boise Bench. Mix of 1940s-60s post-war ranches and 1970s-80s splits. Slightly elevated terrain compared to the Whitewater Park flats. Home values $425K-$685K.
Original Sunset bungalow streets
The earliest Sunset streets, predating the 1940s-50s post-war wave. 1920s-30s Craftsman bungalows and minor revival styles, sometimes with substantial original architectural character. Pre-1940 construction occasional EPA RRP and asbestos considerations. Lots typically 50' × 110'. Home values $485K-$725K.
32nd Street / Esther Simplot Park area
The neighborhoods immediately north of Esther Simplot Park along 32nd Street and surrounding residential streets. Mix of 1930s-50s bungalows and ranches with significant recent investment. Walking distance to park amenities, Whitewater Park, downtown bridges. Home values $525K-$925K.
Sunset window pricing reflects period authenticity premium for pre-1940 bungalows, EPA RRP universal, and the cost difference between restoration ($850-$2,500/window) and replacement ($1,800-$4,500+/window).
Sunset / 30th Street window replacement ranges
Spot replacement (3-8 windows) (Specific windows with HPC-style matching for bungalows): $15,500–$38,000 / 2–4 weeks
1925 bungalow whole-house restoration (Comprehensive restoration of original wood double-hungs): $22,000–$58,000 / 4–8 weeks
Bungalow restoration with storm window addition (Restoration plus period-appropriate storm windows): $28,000–$85,000 / 5–10 weeks
Whole-house premium replacement (post-war) (Full home with premium brand triple-pane on 1945-1985 homes): $32,000–$65,000 / 3–6 weeks
Bungalow HPC-style period-matched replacement (Premium simulated divided light wood matching original Craftsman profile): $58,000–$95,000 / 12–18 weeks
Pricing assumes Iron Crest's standard scope: EPA RRP throughout pre-1978 work, premium brand specification (Marvin Signature, Pella Architect Reserve, Sierra Pacific H3, Andersen E-Series), period-correct divided-light grille pattern matching for bungalow scope, comprehensive flashing integration with WRB and siding, and a 5-year workmanship warranty + manufacturer warranties (typically 20-year structural, 10-year glazing on premium replacements).
Sunset / 30th Street is not within any City of Boise Historic District. There is no Historic Preservation Commission review for these neighborhoods. No HOAs for most Sunset streets — historically working-class to middle-class neighborhoods without modern HOA structure.
City of Boise standard permits apply for electrical, plumbing, structural, and mechanical work. Permit timelines are typically 2-4 weeks for over-the-counter scopes and 3-5 weeks for full plan review with structural drawings.
EPA Lead Renovation, Repair and Painting (RRP) Program applies to virtually every Sunset project given the universal pre-1978 construction. Iron Crest carries RRP certification and follows lead-safe work practices including HEPA containment, wet-paste paint scraping, lead-safe disposal.
Asbestos testing required for pre-1980 demolition work. Common in popcorn ceilings, vinyl asbestos floor tile, sheet flooring mastic, pipe insulation, and sometimes original siding products on pre-1980 Sunset homes. Pre-1940 original Sunset bungalows occasionally have plaster-and-lath walls (rather than later drywall) requiring different demolition practices.
Sunset lots are typically smaller than West Boise or Northwest Boise (50'-60' frontage with 110'-130' depth, often 0.13-0.18 acre) but generally accommodate additions and deck work. Setback compliance occasionally constrains larger detached ADU siting on smaller bungalow streets.
Some Sunset properties along the Boise River corridor are subject to flood plain considerations. FEMA flood zone verification required for any work that affects building elevation, foundation, or substantial scope. Iron Crest reviews flood zone status during pre-construction for river-adjacent properties.
30th Street and 27th Street commercial corridors are within City of Boise transit-oriented development planning overlays in some areas. Mixed-use and small multi-family projects subject to specific design review. Pure residential renovation generally not affected.
Boise River Greenbelt easements occasionally affect rear-yard work on properties backing to the river. Iron Crest verifies Greenbelt easement status during pre-construction.
Window specification for Sunset prioritizes period authenticity for pre-1940 bungalows and premium thermal performance for the broader corridor.
Restoration — original wood double-hung work
Reglazing failing putty (linseed oil-based glazing compound). Chain-and-weight repair or sash chain replacement. Weatherstripping installation (bronze or felt-lined for period authenticity). Sash work to address sticking, painted-shut, or warped conditions. Hardware refurbishment or replacement matching period. Cost: $850–$2,500 per window for comprehensive restoration.
Storm windows — period-appropriate addition
Factory-finished aluminum storm windows in colors matching original (white, almond, bronze) for thermal performance enhancement. Sometimes traditional wood storm windows for premium tier. Cost: $350–$850 per storm window installed.
Marvin Signature — premium replacement
Wood interior with aluminum-clad exterior. Simulated divided light grilles matching original 1925 Craftsman profile. Triple-pane low-E argon-filled standard. Custom sizing to match original openings. Cost: $1,800–$4,500 per window installed.
Pella Architect Reserve — premium replacement alternative
Wood interior with fiberglass-clad exterior. Comparable to Marvin Signature in build quality. Cost: $1,500–$4,200 per window installed.
Sierra Pacific H3 (Idaho-manufactured)
Wood interior with aluminum-clad exterior. Sometimes preferred for projects valuing locally-made products. Cost: $1,400–$3,800 per window installed.
Glazing — triple-pane low-E argon-filled for premium tier
Triple-pane standard for premium Sunset replacement. Low-E coating reduces summer solar gain and winter heat loss. Argon gas fill reduces convective heat transfer. U-factor target ≤ 0.20.

Operable mechanism — double-hung typical for bungalows
Double-hung is original to most Sunset windows. Replacement double-hungs maintain operation type. Sometimes casement windows for accent applications.
Sunset window projects surface specific issues during pre-construction.
- •Universal pre-1978 lead-paint at window assemblies. EPA RRP-certified protocols required. Cost addition: $1,800–$5,500 for window-specific scope.
- •Failed sheathing or framing around window opening. Original construction may have water damage. Repair: $850–$3,500 per window.
- •Inadequate or no flashing in original installation. Pre-1990 windows often have inadequate flashing. New installation requires proper pan flashing, sill flashing, head flashing.
- •Window opening size variations. Original windows sometimes installed in non-standard openings. Custom-sized windows or opening modifications: $300–$1,500 per window.
- •Trim and casing condition (pre-1940 bungalows). Original trim sometimes has substantial period character worth preserving. Refinishing or restoration: $85–$285 per window.
- •Asbestos in glazing putty (pre-1980 windows). Some pre-1980 windows have asbestos in glazing materials. Testing required. Abatement: $1,500–$5,500.
- •Restoration vs replacement decision-making. Cost-benefit analysis of restoration ($850-$2,500/window) versus replacement ($1,800-$4,500+/window). Iron Crest provides specific recommendations during walkthrough.
- •FEMA flood zone for river-adjacent properties. Some 30th Street area properties subject to flood plain. Iron Crest verifies during pre-construction.
- •Original leaded or beveled glass preservation (rare but valuable). Some 1925 bungalows have leaded transoms or beveled glass sidelights worth preserving. Specialty preservation: $1,500-$5,500 per element.

Should I restore or replace my original 1925 wood windows?
Restoration generally preferred where condition allows — preserves period character, often more cost-effective ($850-$2,500/window). Restoration addresses failing glazing putty, chain-and-weight, weatherstripping, sash issues. Replacement ($1,800-$4,500+/window) provides modern thermal performance. Iron Crest provides specific recommendations during walkthrough.
How much does whole-house window work cost?
$22,000-$58,000 for whole-house restoration of 1925 bungalow; $28,000-$85,000 for restoration with storm window addition; $32,000-$65,000 for whole-house premium replacement on post-war Sunset; $58,000-$95,000 for bungalow HPC-style period-matched replacement.
What window brands are appropriate for 1925 Sunset bungalows?
Marvin Signature, Pella Architect Reserve, and Sierra Pacific H3 simulated divided light wood or aluminum-clad wood matching original Craftsman grille pattern (typically 6-over-1 or 4-over-1). Custom-fabricated wood windows for absolute period authenticity. Iron Crest specifies appropriate brand based on owner priorities.
What about storm windows?
Storm windows offer significant thermal performance enhancement to original wood double-hungs without replacement. Factory-finished aluminum storm windows ($350-$850/window) achieve comparable thermal performance to replacement at lower cost while preserving original windows. Sometimes traditional wood storm windows specified for premium tier.
How long does window work take?
2-4 weeks for spot replacement; 4-8 weeks for whole-house restoration; 5-10 weeks for restoration with storm windows; 3-6 weeks for whole-house post-war replacement (after window manufacture); 12-18 weeks for bungalow HPC-style period-matched replacement (manufacturing is the long pole at 8-14 weeks).
Do you handle EPA RRP lead-safe protocols?
Yes — universally required in Sunset given pre-1978 construction. HEPA containment, wet-paste paint scraping with HEPA collection, lead-safe disposal.
Can you preserve original hardware?
Yes when condition allows. Original hardware (sash locks, lifts, pulls) often has substantial period character worth preserving. Refurbishment, replating, sometimes mechanical restoration. Where replacement needed, period-appropriate matching from premium brands.
What's the warranty?
5-year workmanship warranty on Iron Crest's installation or restoration. Restored windows have no manufacturer warranty (period materials).
