How Much Do Replacement Windows Cost? A Complete Price Breakdown by Type, Material, Size, and Installation
The window replacement cost for a home can vary considerably. Window style, frame material, dimensions, glass package, installation method, accessibility, and the condition of the existing opening can all influence the final price. As a general planning range, professionally installed replacement windows can cost anywhere from several hundred dollars to several thousand dollars per opening. For example, HomeGuide estimates that double-pane windows typically cost between $400 and $2,000 per window installed. Premium materials, oversized windows, custom designs, and structural modifications can push the cost higher. Because every home and window opening is different, online prices should be treated as preliminary budgeting estimates—not guaranteed project quotes. This guide breaks down average window prices by type, material, size, glass package, and installation complexity. It also explains what homeowners can expect during a free in-home window estimate. Average Window Replacement Cost at a Glance The following national averages provide a useful starting point: Window category Typical installed cost Double-hung window $325–$1,275 Casement window $400–$1,200 Bay window $2,000–$6,000 Standard vinyl window $250–$900 Fiberglass window $500–$1,500 Wood window $600–$1,400 Double-pane window $400–$2,000 Triple-pane window $450–$3,000 These ranges overlap because window prices are determined by a combination of features. A small premium fiberglass casement window, for example, may cost more than a larger standard vinyl double-hung window. Similarly, replacing a bay window in an existing opening may cost less than constructing a completely new bay window that requires framing, roofing, siding, and interior finishing. Average Window Prices by Type The window’s operating style affects its manufacturing cost, hardware, frame construction, amount of glass, and installation requirements. Double-Hung Window Cost Typical installed cost: $325 to $1,275 per window Double-hung windows are among the most widely used residential window styles. They contain two movable sashes, allowing homeowners to open the window from the top, bottom, or both. Many modern double-hung windows also include tilt-in sashes. This feature makes it easier to clean the exterior glass from inside the home. According to Angi’s double-hung window cost guide, professional installation generally costs between $325 and $1,275 per standard window. The glass type, frame material, window dimensions, panel configuration, and installation location all affect the final price. Double-hung window costs can increase when the project includes: Oversized or custom dimensions Premium wood or fiberglass frames Triple-pane glass Tempered or laminated glass Decorative grids Custom interior or exterior colors Upgraded locks and hardware Multiple windows connected within one opening Second- or third-story installation Damaged framing around the opening Angi also estimates that double-hung windows can cost approximately $40 to $140 per square foot, with larger and custom windows generally costing more. A standard 24-by-36-inch unit may cost between $250 and $850 before labor, while larger configurations can cost considerably more. View Angi’s size-by-size cost breakdown. Double-hung windows are commonly used in bedrooms, living rooms, dining rooms, and traditionally designed homes because they provide flexible ventilation without projecting outward. Casement Window Cost Typical installed cost: $400 to $1,200 per window Casement windows are hinged along one side and open outward, normally using a hand crank. When closed, the sash presses against the frame, helping create a tight seal. According to HomeGuide’s casement window cost guide, casement windows generally cost between $400 and $1,200 per window installed. The window itself commonly costs between $300 and $700, while installation labor can add approximately $100 to $500 per window. Casement windows can cost more than some basic window styles because they require: Hinges Crank mechanisms Locking systems Precise sash alignment Additional operating hardware The following features may also increase the price: Large or tall casement units Paired or triple casement configurations Premium operating hardware Custom frame colors Wood-grain interior finishes Triple-pane glass Tempered or laminated glass Installation in brick, stone, or stucco Casement windows are frequently selected for kitchens, bathrooms, and rooms where homeowners want ventilation without interrupting the view. Bay Window Cost Typical installed cost: $2,000 to $6,000 A bay window normally consists of three connected window sections that project outward from the exterior wall. The center is often a large fixed window, while the angled side sections may be casement or double-hung windows. According to HomeGuide’s bay window pricing guide, a bay window generally costs between $2,000 and $6,000 installed, depending on its dimensions, configuration, frame material, and installation requirements. Bay windows cost more than standard windows because they involve multiple units and may require: Structural support Framing modifications Exterior roofing Flashing and water management Insulation Siding or masonry repairs Interior trim Drywall repair Painting or staining A custom interior seat or shelf The cost is likely to be higher when: A flat window is being converted into a projecting bay The wall opening must be enlarged A structural header must be changed Support brackets or cables are needed Exterior siding, brick, or stone must be rebuilt Custom interior finishing is requested The bay window is oversized Replacing an existing bay window with a similarly sized unit will generally be less complicated than constructing an entirely new bay window. Window Replacement Cost by Frame Material Frame material affects the window’s appearance, price, maintenance requirements, strength, durability, and energy performance. Vinyl Window Cost Typical installed cost: $250 to $900 per window Vinyl is one of the most popular replacement-window materials because it is relatively affordable and requires little routine maintenance. According to HomeGuide’s wood-versus-vinyl window comparison, standard and premium vinyl windows generally cost between $250 and $900 per window installed. Potential advantages of vinyl windows include: Competitive upfront pricing Minimal maintenance No routine painting or staining Resistance to rot and insect damage Good insulating performance Multiple styles and configurations Not every vinyl window offers the same level of quality. Pricing can vary based on: Frame thickness Internal reinforcement Number of insulating frame chambers Weatherstripping Glass package Locks and hardware Interior and exterior colors Warranty coverage Installation method Homeowners should compare the complete construction and specifications rather than assuming all vinyl windows are interchangeable. Wood Window Cost Typical installed cost: $600 to $1,400 per window Wood windows are often selected for their natural appearance,
