Aluminum sash window cost varies by size, style, and installation details. This article covers typical price ranges in the United States, breaks down major cost components, and highlights factors that most influence the final quote. Readers will see per-unit and per-square-foot pricing, plus regional differences that affect price levels and labor rates.

Item	Low	Average	High	Notes
Per unit (standard 2-lite sash, double-hung)	$350	$700	$1,200	Low material quality, basic finish
Per unit (premium finish, low-E glass)	$550	$1,000	$1,900	Higher glazing and hardware costs
Installed price per unit	$900	$1,800	$3,000	Includes labor, removing old sash, and disposal
Per square foot (glazing area)	$25	$40	$65	Depends on frame, glass, and spacer
Average project (4 windows)	$3,600	$7,200	$12,000	Assumes standard labor and common glass

Assumptions: Midwest labor rates, standard aluminum framing, double-hung sash, mid-range glazing, normal access.

Aluminum Sash Window Pricing by Size and Style

Typical total price for a standard 2-lite aluminum sash unit ranges from $350 to $1,200 per unit, depending on glass, finish, and hardware. The largest influence is the glazing package and the sash count per opening. Sizes around 24 in by 36 in are common; 48 in by 60 in multipane configurations push toward the upper end of the range. For multi-lite configurations, per-unit costs rise with additional sashes and hardware complexities.

Scenario	Low	Average	High	Notes
2-lite, standard glass, basic finish	$350	$700	$1,000	Typical starter option
2-lite, low-E or argon glass	$500	$900	$1,500	Energy efficiency adds cost
3-lite or 4-lite designs	$650	$1,100	$2,000	More hardware and assemblies
Premium finishes and hardware	$700	$1,200	$1,900	Durable coatings and hardware

Assumptions: standard residential openings, single-story installation, typical curb appeal finishes.

Labor typically adds $150-$350 per window for removal, frame prep, and installation, depending on existing openings and accessibility. Most jobs take 3–6 hours per window in standard conditions, with adjustments for multi-story work or difficult masonry openings. Scheduling may extend due to weather, lead times for materials, or permit processing.

Component	Low	Average	High	Notes
Labor per window	$150	$250	$350	Basic install with removal
Lead time impact	1–2 weeks	2–4 weeks	6+ weeks	Supply chain varies by region
Install time per unit	3 hours	5 hours	6 hours	Depends on existing trim and wraps

Assumptions: one-story home, no brick removal, standard trim salvageable.

Prices typically rise in coastal and high-cost metro regions, then ease in rural areas with similar material choices. Expect 10–25% higher installed prices in markets like the Northeast and West Coast versus the Midwest or South. Labor rates and permitting requirements drive these differentials, while material costs stay relatively stable across regions.

Region	Installed Price Range (per unit)	Notes
Northeast urban	$1,100–$2,300	Higher labor and permit cost
West Coast urban	$1,150–$2,350	Premium finishes common
Midwest suburban	$900–$1,800	Balanced rates
South rural/suburban	$800–$1,600	Generally lower labor

Assumptions: standard aluminum 2-lite sash, typical residential openings, normal access.

Low-E glass and insulated spacers add roughly $150–$400 per unit over basic glazing. Mirror finishes and dark anodized frames push toward the higher end, while standard finishes stay near the lower end. For replacement only, prices exclude disposal of old units if removal is handled separately by a contractor.

Glass/Finish	Low	Average	High	Notes
Standard glazing	$300	$600	$900	Economy option
Low-E/insulated spacer	$450	$750	$1,100	Energy efficiency boost
Premium tint or gas fill	$500	$900	$1,300	Specialized options

Assumptions: 1/8″ scribe glass to match existing openings.

Disposal, demolition, and trim finishing can add $100–$400 per window. Resealing, hardware upgrades, and extended warranty plans also influence the final quote. If existing framing requires repair, anticipate extra materials and labor. Scheduling a site visit may incur a diagnostic fee in some markets.

Add-On	Low	Average	High	Notes
Old frame removal & disposal	$100	$250	$400	Varies by disposal method
Trim and finish work	$50	$150	$300	Bedroom vs. living area variance
Site prep and sealing	$40	$120	$240	Weather-dependent

Assumptions: standard interior trim salvageable, no brickwork.

Full replacement typically costs more upfront but can improve energy savings and security for years to come. If only a sash or glass pane is damaged, repair may be a cost-effective option, especially for non-structural issues. A partial sash kit can range from $150–$500 per unit, while full frame replacement tends to start around $1,000 per unit installed.

Option	Low	Average	High	Notes
Partial sash repair	$150	$300	$500	Limited scope
Full sash replacement	$800	$1,600	$2,600	Includes frame and hardware
Full frame replacement	$1,000	$1,900	$3,000	Highest price option

Assumptions: standard 2-lite aluminum sash, single opening, normal access.

Extended warranty plans can add $75–$125 per unit per year for coverage beyond a basic year. Consider service fees for on-site visits, annual inspections, and potential repainting or touch-ups after a decade. Long-term ownership costs include maintenance of seals and hardware and potential energy savings from higher efficiency glazing.

Warranty Tier	Cost Range	Coverage	Notes
Basic (1 year)	$0–$25	Hardware only	Free adjustments occasionally
Extended (5–10 years)	$75–$125 per unit/year	Glass, seals, hardware	Annual inspections beneficial
Premium (10+ years)	$120–$200 per unit/year	Full system	Includes replacements under warranty

Assumptions: standard aluminum sash with mid-range hardware.
