Wood window replacement cost

Wood window replacement costs $800 to $3,800 per unit, depending on the size and style. Wood frames provide a classic, natural look and are common in homes in historical districts. However, wood requires more maintenance than other materials and is susceptible to rot.

Composite window replacement cost

Composite windows cost $400 to $2,300 per unit with installation. Many popular brands offer their own proprietary materials that are a blend of aluminum or thermoplastic polymers like PVC and wood fibers.

Awning window

Awning windows cost $400 to $2,000 each, including installation labor. An awning window has hinges on top and opens outward from the bottom to allow ventilation while protecting from the rain. Contractors often install awning windows below large picture windows for added ventilation.

Bay & bow windows

Bay windows cost $2,000 to $6,000 with installation, depending on the size, type, and material. A bay window has 3 or more windows projecting from the home's exterior. A standard bay window features 1 larger central picture window flanked by 2 narrower side windows angled at 30 or 45 degrees.

Bow windows cost $3,000 to $8,000+ and feature 4 to 6+ glass panes installed at a shallower angle than bay windows to create a gentler curve. Bow windows often have stationary panes instead of functional, opening windows.

Double-hung window

Double-hung windows cost $350 to $2,500 per unit with installation. A double-hung window features two operating sashes that slide up and down to allow ventilation on the top, bottom, or both. Many brands offer double-hung windows with tilt-down sashes to make cleaning the outside of the glass easier.

Single-hung window

Single-hung windows cost $300 to $2,100 each for the new unit and labor. Prices vary according to single- vs. double-pane glass types and the credentials of the installer. A single-hung window features one operating sash that slides up from the bottom, while the top sash stays fixed in place.

Garden window

A garden window costs $1,000 to $4,000 with installation, depending on the size and material. A garden window is a glass window box that projects from the exterior of the house, creating a mini-greenhouse. Garden windows often fit well above a kitchen sink to grow plants.

Hurricane / storm window

Hurricane windows cost $400 to $1,200 each with installation or $6,000 to $24,000 total for an average house. Hurricane windows — also called impact windows — withstand a Category 5 storm and are popular in Florida and other coastal states to protect the home's interior.

Storm windows cost $150 to $400 each installed. A storm window fits over your existing windows and reduces noise, adds insulation, and improves energy efficiency. However, unlike impact windows, they don't protect from flying debris or hurricane-force winds.

Picture window

Picture windows cost $300 to $1,300 each with installation, depending on the framing material and size. A picture window is typically cheaper to install than a functional window because there are no moving parts.

Window replacement cost by number of panes

Double- or triple-pane insulated windows cost $400 to $3,000 each with installation. Double-pane windows are the industry standard for new home construction and existing window replacement. Triple-pane windows are more expensive but offer better energy efficiency.

Insulated windows have 2 or 3 panes of glass separated by a space filled with air or inert argon gas to keep heat in during the winter and repel heat in the summer.

Window replacement cost by number of panes
Number of panes Average cost installed
Double-pane window cost $400 – $2,000
Triple-pane window cost $450 – $3,000

*Prices include various sizes and single-hung, double-hung, picture, & casement types.

If only the pane itself has damages, then window glass replacement costs $150 to $500 on average to put a new pane in the existing frame.

Window replacement cost calculator

The window unit itself makes up 65% to 75% of the replacement cost, with labor making up the remaining 25% to 35%, as shown in the table below.

Window replacement cost estimator
Factor Average cost per window
Window $350 – $1,000
Labor / installation $100 – $500
Total cost $450 – $1,500

Factors that affect the cost of window replacement include:

  • Number of windows – The more windows the home has, the higher replacement costs will be. However, replacing all the windows at the same time reduces the overall cost per window.

  • Window size – Larger windows use more materials and may incur higher labor costs because they are heavier and require at least two installers to lift.

  • Window type & style – Small picture windows and standard single- or double-hung windows are the cheapest to replace, while replacing large bay and bow windows costs the most.

  • Window location & accessibility – Labor charges may be higher for second-story windows or if a window is difficult to access, especially when obstructed by other fixtures.

  • New installation vs. existing window replacement – New window installation costs $500 to $2,000 per window, depending on the window size, style, and material. Adding a window where there wasn't one before requires cutting a wall and framing the new opening.

  • Full-frame vs. pocket or inset-style replacement – Full-frame window replacement includes a new window frame and sashes, while pocket-window replacement includes a window that fits inside the existing frame. Pocket-window replacement is common when replacing a window with another of the same size and style.

  • Permits – Changing the window size requires a permit that costs $50 to $200 for reframing the opening. Replacing your current windows with new windows of the same size and type typically doesn't require a permit.

  • RepairsSiding repair costs $2 to $14 per square foot when fixing an old or damaged window that rotted around the frame.

Labor cost to replace windows

Window replacement labor costs $100 to $500 per window on average, depending on whether you hire a handyman or professional window service company.

Handyman rates are $400 to $1,000 to replace one window, including the new window parts and labor. Prices vary widely by the window type and size. However, most handymen offer lower rates per window when replacing all the windows in a home at the same time.

Window upgrade costs

  • Soundproof windows cost $450 to $1,500 per window with installation if replacing only the glass in an existing frame. Replacing the frame and glass costs $500 to $2,000 per window.

Window replacement FAQs

How much does it cost to replace all windows in a house?

Replacing all the windows in a house costs $4,500 to $22,500 total for 10 to 15 standard windows, the total number in an average home. However, your total replacement cost will vary significantly depending on the size, type, material, and number of windows you have.

Are new home windows worth the investment?

Replacing the windows in a home is worth the investment if the existing windows are old, damaged, or if the windows are single-pane. Installing new double-pane or triple-pane windows reduces energy costs and provides a return on investment (ROI) of 75% to 85%.

Is it cheaper to replace all windows at once?

The cost per window is typically cheaper when replacing all the windows at once because window units cost less when purchased in bulk.

How often should windows be replaced?

Replace windows after 15 to 30 years, when the seals begin to leak, or when you notice other signs of damage like cracks or rusted parts that make the window hard to open.

How long does it take to replace a window?

Replacing a window takes 30 to 60 minutes on average for a single-hung window less than 10 square feet. Replacing a large bay or bow window can take up to a full day.

How do you measure for replacement windows?

Follow these steps to measure for replacement windows:

  • Width: Measure the width of your existing window at the bottom, middle, and top. Measure the distance between the jambs—the vertical boards that form the sides of the window frame. Write down the shortest width.

  • Height: Measure the height of your existing window at the left, center, and right. Measure between the head jamb—the top horizontal board on the frame—to the sill the bottom of the window sash rests on. Note, the sill is within the frame, not the trim board that extends into the room. Write down the shortest height.

Getting estimates from window installers near you

Follow these guidelines when hiring a window installer near you:

  • Choose only licensed, bonded, and insured window installers.

  • Compare at least 3 estimates for windows of the same material and quality.

  • Avoid the lowest estimates that may indicate poor quality or workmanship.

  • Read reviews from previous customers on HomeGuide and Google.

  • Request a written contract, payment terms, and warranty details before the project begins.

  • Negotiate a payment plan with a reasonable deposit.

  • Make the final payment only when the work has passed inspection.

Questions to ask

  • Ask these important questions when choosing a window replacement company:

  • How many years have you been in business?

  • What brand and style of windows do you recommend for my home?

  • How much will the new windows cost?

  • Does this estimate include the new window, labor, new parts, and cleanup?

  • What other associated costs should I expect?

  • How long will it take to install the new windows?

  • What does the warranty cover, and how long does it last?
