This article breaks down the cost of aluminium windows, including typical total prices, per-window and per-square-foot ranges, and the main drivers that influence a final quote. The term aluminium window price covers frame, glass, hardware, and installation. Prices vary by size, finish, glass type, region, and labor costs.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Typical 3’ x 5’ single-hung aluminium window | $320 | $520 | $900 | Includes frame, sash, standard glass |
| Per sq ft (frame and sash only) | $40 | $60 | $85 | Excludes glass upgrades |
| Standard double-glazed IGU with low-E coating | $60 | $95 | $140 | Installed per sash |
| Labor for installation per window | $150 | $350 | $700 | Includes removal of old window in most regions |
| Permits and disposal | $0 | $120 | $300 | Depends on local rules and old window removal |
Assumptions: Midwest or Southern U.S. labor rates, standard white or anodized finish, typical residential single-story installation, standard glass with no coatings, no special weather seals.
Price Range by Window Size and Style
Aluminium windows cost by size and style, with common residential options ranging from small single-hung units to larger picture or slider designs. Expect a typical total per-window price between $320 and $900, depending on sash count, operability, and glazing. Larger 5’ x 6’ units frequently exceed $1,000, especially when mixed with premium glass.
Smaller windows with basic glass can stay near the $320–$520 range, while mid-size units with double-glazed glass and basic hardware cluster around $520–$800. Premium hardware, triple glazing, or specialty coatings push toward the $1,000–$1,400 band for a single unit. Assumptions: standard installation, normal access, mid-range fabricator pricing.
Material and Finish Impacts on Aluminium Window Cost
Finish and alloy grade affect both price and durability. White powder-coated frames are usually cheaper than anodized or bronze finishes, while higher-strength alloys with reinforced corners add cost. Thicker frame profiles add mass and labor time, increasing price per unit.
Perimeter gaskets, thermal breaks, and color-cured finishes contribute to a higher price tier. For a typical home, expect the finish choice to move a window from the $420–$600 range up to $650–$1,000 per unit when premium finishes are selected. Assumptions: mid-range finish options, standard black or white colors, standard hardware.
Glass Type and IGU Configurations Drive Price
Glass upgrades are a major cost lever. Single-glazed aluminium windows are rare in new builds; most installs use double-glazed IGUs with low-E, which adds to the base price. Triple glazing or high-performance gas-filled units further increase costs.
Common configurations are 1/8″ or 1/4″ glass with a spacer, and low-E coatings add roughly $20–$60 per sash for standard sizes. For a 3’ x 5’ unit with double glazing, expect $60–$140 above frame-only pricing. Assumptions: standard inert gas, typical spacer width, standard low-E coating.
Region and Market Variations in Aluminium Window Prices
Geography matters. Coastal markets and large metros typically incur higher labor and material premiums than rural areas. Regional supply chains, permit costs, and contractor availability all shift quotes.
In the Northeast or West Coast, a mid-range 3’ x 5’ window might run $600–$900, while in parts of the Southeast or Midwest the same unit can land at $420–$750. Assumptions: standard single-story home, normal access, no unusual site constraints.
Add-Ons That Elevate the Price: Screens, Grilles, Coatings
Optional components add to the total. Installed insect screens, decorative grilles, hardware upgrades, and weatherproof seals can increase price by 10–30% per unit when bundled.
Security hardware, tilt-and-turn mechanisms, and internal blinds add more. A typical package for one window with basic screen and a grille can add $60–$180. For premium grilles and integrated blinds, budgeting $200–$450 per window is reasonable. Assumptions: mid-range options, standard screen size, no custom grille patterns.
Labor, Permits, and Installation Time Impact on Total Cost
Installation complexity matters. Labor often represents 40–60% of the total window price when replacing existing units, and can exceed 60% on custom builds with unusual openings.
Labor per unit commonly ranges from $150 to $700 depending on accessibility, removal of old windows, and frame fit; more complex installs may require extra crews or extended tear-out. Permits can add $0–$300 per opening. A multi-window project typically enjoys lower per-window labor due to scheduling efficiency. Assumptions: standard retrofit, urban contractor rates, no heavy structural work.
Maintenance and Warranty Costs Over Time
Ongoing costs influence the long-term value. Most aluminium windows carry a 10–20 year warranty on hardware and frame, with maintenance checks recommended every 2–3 years.
Annual upkeep is usually nominal, focused on hardware lubrication and seal inspection. Some high-end packages include extended warranties that raise upfront costs but reduce later expenses. Assumptions: standard warranty terms from a mid-range manufacturer.
Replacement vs New Install Cost Scenarios
Choosing between replacement and new installation changes the price trajectory. Replacing only the sash or glazing can be cheaper than full frame replacement in some cases, but full-frame aluminium windows offer better efficiency and durability.
For retrofit projects, per-window costs often fall in the $320–$700 range, depending on old frame remove, wall cavity access, and alignment. New construction windows, with custom openings and high-end glass, can push to $900–$1,400 per unit or more. Assumptions: standard wall condition, no structural repairs, mid-range glass.
