The cheapest window options available are usually single-pane glass and single-hung options, starting at around $100 before installation. These only have one layer of glass, and only half of the unit opens out. Double-pane models start around $250 before installation.
Keep in mind that the right choice isn’t always the cheapest option. Double-paned windows may cost more, but they’re better at blocking sound and heat transfer than single-hung versions. When selecting single vs. double-hung windows, chances are the right decision will come down to personal preference.
| Window Type | Cost |
|---|---|
| Single-Pane, Single-Hung | $100–$300 |
| Double-Pane, Single-Hung | $200–$400 |
| Double-Hung | $250–$500 |
A few factors that could influence the cost of your windows include:
Frame material
Energy efficiency
Hardware
Style
Type of glass
Amount of insulation
Talk to a local window installer to get pricing specific to your home project.
Tip: Replacing all of your home’s windows at once can help you save money on installation, but it depends on the style. For example, bay windows cost $400 to $3,250 each. Triple-glazing, low-E coating and built-in shades can all add to the cost of your project.
The best value windows depend on your home’s needs. If you live in a harsh climate, you may want to invest more in windows with good insulation. If you frequently experience storms, you may want to pay for stronger materials to withstand strong winds or hail. The cost to install windows varies greatly based on your needs.
Budget options can be a great way to save money on replacement windows, but there may be a few drawbacks. Disadvantages can include:
Less insulation
Less aesthetically pleasing
Fewer options to choose from
More frequent replacement
More maintenance
Window frames can range from $300 to $2,000 depending on the material you choose. Options for this project include vinyl, aluminum, fiberglass and more. All of the pricing below is before installation.
Vinyl frames can be an inexpensive option, with products as low as $250. These frames don’t require much maintenance, but they may not be as sturdy as other options.
Aluminum frames run from $400 to $1,200 or more depending on the size and brand. Though sturdy, this material can be difficult to paint and doesn’t always insulate well.
Fiberglass frames are a more expensive option and run from $600 to $1,000. Fiberglass material is durable and a good insulator.
Wood window frames run from $600 to $2,000 on average and can be an attractive option for your home. This material requires regular maintenance like painting and finishing.
| Window Frame Material | Cost |
|---|---|
| Vinyl | $250–$1,000 |
| Aluminum | $400–$1,200 |
| Fiberglass | $600–$1,000 |
| Wood | $600–$2,000 |
Choosing cheap vinyl frames or aluminum options can help you cut the cost of your project by 50% or more. Premium options like wood or fiberglass look high-end and may last up to 50% longer, but they’ll cost more. Find a window installation pro to see which options will work best for your space.
The best place to buy windows for your home project varies. Big box stores may be more accessible with more options than a local store, but may not offer a personalized shopping experience. Local stores may be able to meet custom orders and have knowledge of window needs in your area, but may not have as many options available to choose from.
| Seller | Pros | Cons |
|---|---|---|
| Big Box Stores | Possibly lower prices | Not always tailored to your home |
| Small Chains | Slightly pricier products | May have custom options, higher quality |
| Online Retailers | Easy to find and use | Can be difficult to get true idea of colors, material quality, etc. |
| Window Installers | Knows which windows will work best in your home | Not a DIY option |
