How to Use the Window Replacement Cost Calculator

The Window Replacement Cost Calculator helps homeowners estimate the cost of replacing their windows, including window type, size, material, labor, and optional window screen replacement in your home, shed or even garage. Follow these steps to calculate the total cost of your window replacement project.

Step 1: Select Window Type

Choose the type of window you are replacing. Each type has a different cost based on its complexity, design, and installation requirements.

• Single-Hung – One movable sash, lower cost.
• Double-Hung – Both sashes move, slightly more expensive.
• Casement – Hinged at the side, crank-open mechanism.
• Sliding – Opens horizontally, cost-effective.
• Bay & Bow Windows – Large, decorative, and more expensive.
• Awning – Hinged at the top, opens outward.
• Picture – Fixed, large glass panel, generally cheaper.

Example: If you are replacing three double-hung windows, select “Double-Hung” in the dropdown menu.

Step 2: Enter Window Dimensions

Enter the width and height of your window in inches. This helps determine the material cost based on the total size of the window.

Example: If your window is 36 inches wide and 48 inches high, enter 36 for width and 48 for height.

Step 3: Enter the Number of Windows

Enter the total number of windows you need to replace. This helps calculate the total material and labor costs.

Example: If you need to replace 5 windows, enter 5 in the quantity field.

Step 4: Select Window Frame Material

Choose the material for your new windows. Each material has a different cost and durability.

• Vinyl – Affordable, low maintenance.
• Aluminum – Durable, weather-resistant.
• Fiberglass – Stronger, energy-efficient.
• Wood – Classic look, requires maintenance, more expensive.

Example: If you prefer low maintenance and affordability, select “Vinyl.”

Step 5: Enter Labor Cost Per Window

Labor costs vary based on location and contractor rates. If you have a quote from a contractor, enter the cost per window for installation.

Example: If installation costs $150 per window, enter 150 in the labor cost field.

Step 6: Include Window Screen Replacement (Optional)

If you also need to replace your window screens, select “Yes” and enter the cost per screen.

Example: If screen replacement costs $50 per window, enter 50 in the screen cost field.

Example Calculation

A homeowner wants to replace three double-hung vinyl windows with the following details:

• Window size: 36” x 48”
• Material: Vinyl
• Labor cost per window: $150
• Window screen replacement cost per screen: $50

Step-by-Step Calculation:

1. Window Cost: $200 per window × 3 windows = $600
2. Labor Cost: $150 per window × 3 windows = $450
3. Screen Cost: $50 per screen × 3 windows = $150
4. Total Replacement Cost: $600 + $450 + $150 = $1,200

This gives the homeowner with a clear estimate on the price before committing to a contractor or supplier.

Why Use The Window Replacement Cost Calculator?

Windows have a high variety of lifespans and can depend on many factors. If you just bought a new home like myself, you shouldn’t have to worry about replacing your windows anytime soon because most new home builders do a proper job sealing them when building the home and installing the windows. Most windows can last anywhere from 15 to 30 years, or 30 years if they are sealed properly—especially in the northern hemisphere, meaning Canada and the northern United States.

Winter can affect the lifespan of your windows. If you see frost inside your home window, that means it’s not sealed properly, and you should get it looked at. It could be a simple fix, or you might even have to replace the frame. If you buy an older home that’s older than 15 years you might have to get a better inspection of the windows and how good they are sealed, you do not want to purchase a home not knowing if you’ll have to replace the windows as soon as you move in.

These days, windows are expensive, especially when you add labor costs. Window installation labor costs can range anywhere from $300 to $600 per window, and if you have six windows to install, that’s a whopping $3,600 that you could actually keep in your pocket. Installing windows is fairly easy.

With the right tools and proper preparation, it’s possible for anyone to replace their own home window. First, you’re going to want to take a measuring tape and measure the height, width, and diagonal length of your current window inside the current window frame. Compare your measurement to your new, replacement window to make sure that it will fit inside your current window frame – otherwise, you will need to purchase a new frame that your new window will be able to fit inside.

As your next step, you will need to remove your old window from its frame. First, locate the inside stop pieces located on the left and right sides of the window and carefully remove them. If necessary, use a tool such as a flat bar to assist with this. The stop pieces will be reattached upon insertion of the new window, so try to remove them without damaging them. This should allow you to remove the inside sash – or window piece – out of the window frame. Then, move the outside sash to the bottom of the window frame, making sure to exterior stop pieces inside the window frame. After this is done, clean up the window frame in preparation for the installation of the new window. Remove any errant nails or screws with a hammer, clean off any old caulk with a utility knife, and remove any weights that may be inside the window frame.

To install your new home window, first apply a thin line of caulk around the outside stops of the window frame. Then, vertically center both the outside and inside sashes of your new window inside the window frame. There should be around four ‘mounting holes’ visible in the sashes – line them up with the holes in the frame. Place the new window sashes inside the window frame, lining them as appropriate, and using a balance to make sure that everything is level. Next, use a screwdriver to screw four screw into the mounting holes. After examining your new window to make sure that everything is level and that there are no gaps, apply another layer of caulk to the inside of your window. Finally, re-attach the inside stop pieces. Your new home window is now finished!
