Use this cost guide to help you budget for your window replacement — whether you’re getting one new window or a whole house of them.

What Are Some Signs Your Windows Need to Be Replaced?

The most obvious reason to consider window replacement is damaged windows. Cracked or chipped panes make your windows less energy-efficient and allow intruders easier access to your home. There may be damage to your windows that you can't see if the glass appears foggy or there's condensation on the inside of the window. However, condensation between the glass layers or on the outside is usually no cause for alarm.

It may also be worth replacing your windows if you notice signs that your existing windows aren't energy efficient. Drafts, substandard installation or rocketing heating bills could all indicate inefficient windows. You may also wish to invest in window replacement if your windows look dated or are difficult to open. Sometimes, old windows allow too much UV light inside your home, causing floors, furnishings and wallpaper to fade prematurely.

What's the Average Price Per Window?

According to Bob Vila, the national average window replacement cost is around $650 per window. You might pay anywhere between $200 and $1,800. The overall cost depends on the types of windows and frames you want and the labor rates in your area.

What Other Factors Affect the Cost of Window Replacement?

Window replacement costs vary widely depending on a range of factors. Larger windows generally cost more, so expect to pay extra to replace large fixtures like bay or basement egress windows. Windows with multiple panes of glass are also costlier. For example, you should expect to pay between $300 and $700 to replace a bedroom window, but costs go up to an average of $1,800 for a bay window with three panes.

Energy-efficient or tinted glass is more expensive than regular glass. Some areas mandate tempered glass for certain homes, so you may not have a choice there.

The frame material also makes a significant difference to the overall window replacement cost. Vinyl window frames are usually the most affordable option, costing between $100 and $900 per window. Meanwhile, pricier composite window frames could set you back between $300 and $1,200 on average.

Finally, your home's age could affect the cost of replacing your old windows. Replacement windows for an older property can cost more than double the price of a newer build because the surrounding structure may require repair or updating. You may also need custom windows to replace non-standard window sizes. Older homes are also less likely to have retrofitted windows. Retrofitted windows are cheaper to replace because they allow the installer to remove and replace the glass without interfering with the frame or surrounding walls.

How Much Do Window Installers Charge Per Hour?

Modernize says you should expect to pay between $100 and $250 in labor costs per window, based on an average hourly rate of $38. However, the going labor rates vary widely depending on where you live. Generally, window installation labor is more expensive in places with higher costs of living. You may also need to pay more for challenging or unusual window installation jobs requiring specific skills and expertise.

Are Energy-Efficient Windows Worth the Extra Cost?

Energy-efficient windows carrying the government-endorsed Energy Star certification are generally more expensive than regular glass. However, they could save you a significant amount of money on your energy bills because they provide better insulation and prevent heat loss from your home. Some energy-efficient windows also limit the amount of UV light that can pass through, protecting your furnishings and decor from sunlight damage.

According to Energy Star, a family living in a 2,000-square-foot home could save between $125 and $340 per year by replacing their single-pane windows with energy-efficient alternatives. Meanwhile, you could save $20 to $70 per year when you replace clear, double-glazed glass with Energy Star-approved windows.

Therefore, it's important to weigh up the potential energy savings compared to the added cost of installing energy-efficient replacement windows. Many homeowners also feel that paying extra for energy-efficient windows is worth it because it reduces their energy usage and makes their homes more environmentally friendly.
