Factors that affect window replacement cost
Window replacement costs break down into two main categories: Materials and labor. Materials refers to the cost of the physical windows you’re buying, while labor is the price you pay to have them professionally installed. A number of factors can affect both your materials and labor costs for replacement windows. Knowing these allows you to budget accordingly and choose the best window type to suit your spendings.
- Location: States with a higher cost of living tend to have more expensive prices, both for materials and for labor.
- Style of window: There are many styles and window frame materials available, which can affect the price range. A large bay window, for example, tends to cost more than your traditional double-hung window.
- Window material: Durable, energy-efficient materials — such as composite — are more costly than weaker materials like vinyl.
- Number of windows: The bigger your house, the more windows you’ll need to replace and the more you’ll pay to replace them all.
- Brand: Window manufacturers often sell brands at different price points. More expensive brands may use different materials or have a more high-end look.
- Labor experience: A company with a wealth of experience and a large staff may quote you a higher price for installing windows, but your end result may be better than opting for a new business with a lower price but without many reviews.
- Energy efficiency: More energy-efficient windows may come with a larger upfront fee, though they can often save you money in the long run in your energy costs.
- Age of house: Older houses are more prone to cracks and could require additional repairs to support your new window.
- Window location: Windows that are difficult or dangerous to reach may require your installer to bring in additional materials, such as scaffolding and protective equipment. This can increase labor costs.
- Condition of window frame: Ideally, you’ll just need to replace your windows. But if the wood framing that supports the window is in poor condition, you may need to replace or reinforce it – which can add to your costs.
Window replacement cost by window type
Window replacement cost depends hugely on the window type. Larger and more ornate windows typically cost more. Below are some of the most common window styles and how much they cost to replace.
Single-hung window replacement cost
Cost: $150–$400 per window.
Single-hung windows feature two sashes, called panels. The lower sash can move up and down while the upper sash remains stationary. When you open the window, the top sash is partly covered, compared to a double-hung window that has upper and lower sashes that stay open simultaneously.
Double-hung window replacement cost
Cost: $200–$600 per window.
Double-hung windows are one of the most popular types in the United States. They’re characterized with two operating sashes that move up and down to allow ventilation across all areas of the window frame. This added feature — along with high energy-efficient levels — make them more expensive than single-hung windows.
Arched window replacement cost
Cost: $350–$850 per window.
Arched windows feature square bottoms with an arch or half-circle at the top. Compared to rectangular windows, this type can be more challenging to install, as they require a precise size and shape of the opening, so attention to detail is key. For this reason, they’re generally more expensive to manufacture and install than the average window replacement cost.
Bay window replacement cost
Cost: $900–$2,200 per three-panel.
Bay windows project outward from a building’s external wall. These windows are typically polygonal or rectangular with average internal angles of 90 degrees, 135 degrees and 150 degrees.
Bay windows are available in several types — angled, boxed and energy-efficient — with the latter being the most costly and boxed being the most budget-friendly. Some bay windows may have a small roof that sticks out over the window itself, so you may need to fork out on roof adjustments. Additionally, these windows have three sides, which can make installation more difficult, increasing the cost.
Casement window replacement cost
Cost: $350–$900 per window.
These windows are attached to a frame by one or multiple hinges with an automatic or manual mechanism that opens the window outwards. This design makes them excellent for ventilation. Casement windows are within the average window replacement cost.
Picture window replacement cost
Cost: $350–$800 per window.
Picture windows are a single window pane that makes the view of outside appear like, well, a picture. They’re usually larger than regular windows, and they’re usually fixed, meaning they don’t open. This option, along with a simple installation (no awkward shapes) makes its costs slightly lower than the average cost to replace windows.
Sliding window replacement cost
Cost: $250–$1,800 per window.
Sliding windows open by moving them horizontally across a top and bottom track in the window frame. These windows are commonly found overlooking gardens to provide maximum view and ventilation as well as convenient access. Since they’re larger in height than most windows, the cost for materials and labor can be significantly higher than the national average.
Skylight window replacement cost
Cost: $850–$2,500 per window.
Skylight windows are set into a pitched or flat roof to allow lots of natural light to flow in the room. The vast price range for skylight windows is down to the huge variety of designs available. This includes a fixed or opening format, self-cleaning glass on the outer pane and solar protection. As this window type is more difficult to reach, the installation cost is more expensive than the average window replacement cost.
Common window materials
The cost to replace windows can depend on the window material, so knowing the price and features of each material can help you to plan your budget.
- Aluminum. With a price between $80–$500 per window, aluminum is the most affordable material and features long-lasting durability and minimal maintenance. However, it’s not the most energy-efficient option, and this material can expand and contract in temperatures, resulting in more regular replacement.
- Vinyl. Also reasonably priced $150 to $600 per window, vinyl windows are also durable . but provide excellent energy efficiency, too. Vinyl lacks as many customization options as other materials, though you can create a wood-like finish without the cost of a wood frame.
- Wood. Wood adds a timeless finish to windows but can require more maintenance than aluminum and vinyl. The huge price range, between $250 and $800 per window, indicates the many wood options available with each providing different durability characteristics.
- Composite. Composite windows are one of the more expensive materials at $400–$1,300 per window, due to the increased durability compared to wood or vinyl windows. Though compositie might not be as energy-efficient as vinyl, it has a stylish finish like wood.
- Fiberglass. Running between $700–$1,400 per window, fiberglass tends to be the most expensive window material on the market. This is because of its excellent weather-resistance and insulation from extreme external temperatures. While they may not be as popular, they’re durable and require minimal maintenance.
Can you replace windows yourself?
DIY window installation is possible and an effective way to cut costs. However, we only recommend you install windows yourself if you’re knowledgeable and have all the tools you’ll need. Almost all replacement windows are custom-made, so you’ll need to know how to measure the window accurately.
Hiring a professional alleviates the pressure on you and will likely improve the overall installation quality. A professional fitter is less likely to damage flooring or walls and can install your replacement window quicker than you can yourself.
