Your windows are drafty, the seals are failing, and your energy bills keep climbing. You know replacement windows will help, but the quotes you receive vary significantly. Understanding the cost per window helps you compare quotes and budget for the project. Window replacement is one of the most effective home improvements for energy savings, but the investment varies widely depending on the window type and frame material you choose.
Window replacement costs $300 to $1,200 per window installed for most standard sizes. The average double-hung vinyl window costs $400 to $800 installed. The total cost for a home with 10 windows ranges from $5,000 to $15,000. The cost per window depends on the window type, frame material, glass options, and installation method required for your home.
Cost by Window Type
Single-hung windows are the most affordable option at $300 to $600 installed. These windows have one movable sash and are simpler to build and install than other types. They are a good choice for budget-conscious homeowners and rooms where ventilation from both top and bottom is not needed for the function of the room.
Double-hung windows cost $400 to $800 installed. Both sashes move, allowing ventilation from the top and bottom. This is the most popular window type for residential homes because of the versatility in ventilation and the classic appearance. Double-hung windows are available in all frame materials and a wide range of sizes for most homes.
Casement windows cost $450 to $900 installed. These windows open outward with a crank mechanism and provide excellent ventilation because the entire window opens. Casement windows seal tightly when closed, making them more energy efficient than sliding windows. They are popular in kitchens and bathrooms where easy operation is valued.
| Window type | Cost installed | Energy efficiency | Best for |
| Single-hung | $300 to $600 | Moderate | Budget projects |
| Double-hung | $400 to $800 | Good | Most homes, classic look |
| Casement | $450 to $900 | Excellent | Hard to reach areas |
| Slider | $350 to $700 | Moderate | Wide openings |
| Picture | $500 to $1,000 | Excellent | Large fixed views |
| Bay or bow | $1,200 to $3,500 | Good | Dramatic look, extra space |
Cost by Frame Material
Vinyl window frames cost $300 to $800 installed. Vinyl is the most popular frame material because it is affordable, energy efficient, and maintenance-free. Vinyl frames do not rot, peel, or need painting. They provide good insulation with multi-chambered designs. Vinyl windows last 20 to 40 years and offer the best value for most homeowners looking to replace older windows.
Wood window frames cost $600 to $1,500 installed. Wood provides natural insulation and a traditional appearance that many homeowners prefer for historic or high-end homes. Wood windows can be painted or stained any color. They require regular maintenance including painting or staining every three to five years. Wood frames last 30 to 60 years with proper care and maintenance.
Fiberglass window frames cost $600 to $1,200 installed. Fiberglass is stronger than vinyl and offers better insulation. It expands and contracts at the same rate as glass, which reduces stress on the seals. Fiberglass frames last 40 to 60 years and can be painted any color. They are more expensive than vinyl but offer superior durability for long-term homeowners.
Aluminum window frames cost $300 to $700 installed. Aluminum is lightweight, strong, and affordable. However, aluminum conducts heat and cold easily, making it the least energy-efficient option. Aluminum frames are commonly used in commercial buildings and warm climates where insulation is less critical for the home comfort and energy efficiency.
Full-Frame vs Insert Replacement
Full-frame replacement costs $500 to $1,200 per window. The old window is removed down to the rough opening and a completely new frame is installed. Full-frame replacement is necessary when the existing frame has rot, water damage, or is no longer square. This method provides the best energy efficiency because the new frame can be properly insulated and sealed around the entire opening.
Insert replacement costs $300 to $700 per window. The new window fits into the existing frame without removing it. Insert replacement is faster and less expensive but is only suitable when the existing frame is in good condition. Insert windows are slightly smaller than the original because they fit inside the existing frame, which reduces the glass area slightly.
The installation method affects the total cost per window significantly. Full-frame replacement costs $200 to $400 more per window than insert replacement but is necessary when the existing frame is damaged. Most window companies recommend full-frame replacement for older homes where the existing frames may have deteriorated over time due to weather exposure and age.
Glass Options and Add-Ons
Double-pane glass is standard in most replacement windows. Low-E coating adds $30 to $80 per window and reflects heat back into the room in winter while blocking solar heat in summer. Argon gas fill between the panes adds $20 to $50 per window and improves insulation by 15 to 20 percent compared to air-filled windows. These options improve energy efficiency and comfort.
Triple-pane glass adds $100 to $300 per window over double-pane pricing. Triple-pane windows provide the best insulation and noise reduction. They are recommended for homes in very cold climates or near busy roads where noise is a concern. The additional energy savings from triple-pane glass may take 10 to 20 years to offset the higher upfront cost of the premium windows.
Energy Star certified windows cost 10 to 15 percent more than standard windows but can reduce heating and cooling costs by 10 to 30 percent per year. The federal energy tax credit covers 30 percent of the cost of Energy Star windows up to $600 per year, which helps offset the higher cost of energy-efficient windows for homeowners who plan to stay in their home.
Factors That Affect Cost Per Window
The number of windows affects the per-window cost. Most companies offer volume discounts for replacing multiple windows at once. Replacing all windows in a home at the same time costs $50 to $150 less per window than replacing windows one at a time. The installer can work more efficiently when all windows are replaced together in a single project.
Window size and accessibility matter. Standard size windows cost less than custom sizes. Second-story windows cost $50 to $150 more per window because of the additional labor and equipment needed for safe installation at height. Windows in hard-to-reach locations may require special equipment and add $100 to $300 per window to the total project cost.
Permit and disposal fees add $50 to $200 to the total project cost. Most areas require a building permit for window replacement. The contractor typically handles the permit process and includes the fee in the quote. Old window disposal costs $5 to $15 per window for standard sizes and is usually included in the installation price.
A window installer with 22 years of experience said: “The most common mistake I see homeowners make is choosing the cheapest windows available without considering installation quality. You can buy the best windows on the market, but if they are installed incorrectly with gaps in the insulation or improper flashing, they will perform worse than a mid-grade window installed correctly. The installation matters as much as the window itself.”
