What affects window replacement costs?

Several key factors influence the overall cost of replacing windows in your home. The price can vary based on:

  • Window Type & Style: Larger or custom-designed windows generally cost more than standard options.
  • Material Choice: Vinyl, aluminum, wood, and fiberglass all have different price points and energy efficiency levels.
  • Number of Windows: Replacing multiple windows at once can sometimes lower the per-unit cost.
  • Installation Complexity: Windows in hard-to-reach places or requiring structural changes may increase labor costs.
  • Labor & Home Condition: Professional installation ensures quality but adds to the total price, especially if your home needs additional work.

How much do new windows costs?

Before requesting quotes for window replacement, it’s important to define your needs and preferences. Several factors influence the total cost, including the type of windows, frame material, energy efficiency upgrades, and installation complexity.

On average, installing a standard-size double-hung vinyl window costs between $500 and $2,500 with additional labour/installation costs. A small, professional crew can install a single ground-floor window in about an hour. Larger, or harder to access windows may occasionally require additional costs.

While window replacement can be a significant investment, well-maintained window can last 15 to 25 years and offer a high return on investment (ROI). Homeowners can typically recoup 71% to 78% of the cost at resale, making new windows a smart financial and aesthetic upgrade.

Window Replacement Costs By Material

Material Cost Range Average Cost
Aluminum $600-$5000+ $850-$3500
Vinyl (uPVC) $300-$3000+ $800-$1500
Fiberglass $450-$4000+ $650-$2500

Aluminum Windows

Aluminum windows are one of the most budget-friendly frame options, with prices ranging from $600 to $5,000 per unit, and an average cost of $850 to $3,500. Their affordability makes them a practical choice for cost-conscious homeowners. However, aluminum frames are less energy-efficient and versatile than vinyl or wood, which has led to a decline in their popularity over the years.

Premium Vinyl Windows

Vinyl windows are the most popular option for modern homes, offering excellent energy efficiency and versatile design options, including trims that mimic traditional wood for both interiors and exteriors. The cost of vinyl windows varies depending on style and features, typically ranging from $300 to over $3,000 per unit. However, the average price for a mid-range double-hung vinyl window replacement falls between $800 and $1,500.

Fiberglass Windows

Fiberglass windows are a premium option known for their durability and aesthetic versatility. However, their higher price point makes them less common than vinyl options.

Vinyl Window Replacement Costs By Style & Size

Window Style Average Estimated Cost
Architectural Windows (Shaped) $500-$3500
Awning Windows $500-$1250
Bay Windows $2750-$5500
Bow Windows $2750-$5500
Casement Windows $500-$1250
Hopper Windows $500-$1250
Hung Windows $500-$1250
Slider Windows $500-$1250
Tilt-and-Turn Windows $750-$1750

The cost of a window replacement project generally increases with window size – it’s simple, larger windows require more materials and labour. Additionally, the type of window plays a significant role in pricing, as some styles are inherently more expensive due to their design, functionality (hardware), or energy efficiency features.

Bay & Bow Windows

Bay & bow windows are a style of window that protrudes from the exterior wall and creates a recessed area inside the home. Due to their larger size and increased number of panels, bay & bow windows can be costly to replace. The structural complexities associated with bay & bow windows contribute to their high price range, which can range from $2,750 to over $5,500.

Casement Windows

Casement windows operate using a hand crank and swing outward on hinges (like a door). They cost around $500 to $1,250 per unit, including labour, on average, with variations based on size, location, and energy-efficiency options. Larger windows in hard-to-reach places typically cost a little more.

Egress Windows

Egress windows, which also serve as emergency exits, are commonly installed in finished basements and attics. In basements partially below ground, these windows are paired with a window well on the exterior, providing enough space to climb out. With various styles available, the cost of egress windows ranges from $500 to over $1,250, excluding the installation of the window well.

Hopper Windows

Hopper windows open inwards towards the interior of the house, unlike awning windows that open outwards towards the exterior. Their price range between $500 to $1,250+.

Single or Double-Hung Windows

Single-hung windows have a fixed top sash and a movable bottom sash for ventilation. Double-hung windows are ideal for enhancing air circulation in your house, with an operable upper sash and bottom sash. The price of double-hung windows is comparable to single-hung windows, with an average price range of $500-$1,250.

Slider Windows

Slider windows, also known as gliders, consist of two sashes where one is fixed while the other one slides horizontally. These windows are commonly installed on the ground level as they are easier to clean. Their cost varies based on the desired size and energy-efficiency options, and can range from $500 to over $1,250.

Whole House Window Replacement Costs

Several factors determine the total expense of replacing all house windows, including the number, labor costs, size, and type. Below is a table with approximate figures, based on an average window cost of $800 and labor at $50 per hour, with each window taking about an hour to replace.

Number of Windows Average Estimated Costs
1 - 6 $4,840 - $6,120+
8 - 12 $6,120 - $8,680+
12 - 16 $8,680 - $11,240+
