After deciding on all of these factors, you can determine the cost of your custom windows.

Replacement Window Costs & Types

Wood windows have long been a traditional favorite for replacement windows. They’re an attractive option to many homeowners, thanks to their aesthetic beauty and insulative properties. They’re an especially smart choice since they last for decades—often up to thirty years or more. However, their superior lifespan comes with necessary maintenance in order to prevent rotting and corrosion.

As a more low-maintenance alternative, vinyl windows are another popular choice, with more than half of homeowners choosing them for their replacement windows. It’s easy to see why, since they’re durable, resilient against inclement weather, rot-resistant, and energy efficient.

Vinyl windows offer the traditional beauty of a classic wood frame without the necessary maintenance or the high price tag—they have a lower overall job cost and a higher ROI than wood windows.

Much like vinyl windows, aluminum frame windows are a popular choice of replacement window because of their low maintenance, durability, and affordability (with an average cost of $550-$750 per double hung aluminum window). The drawback, however, is that because of their high thermal conductivity, these frames retain heat and cold more easily and are therefore also more prone to condensation.


Other Replacement Window Costs

New Construction Windows Versus Simple Replacement

Look at your current window frames—are they rotting? Rotten window frames must be replaced, so you’ll need new construction windows rather than replacement windows. New construction windows are a bit more expensive and have higher installation costs, too. Factor in spending about $50 to $100 more per window for new construction windows—but also make sure to get estimates from several different window contractors in your area.

Add in Any Fees

Many window contractors or large window companies will add fees such as delivery charges, so you’ll need to account for these as well. It’s important to ask about any additional fees that you’ll be charged and make sure that you account for them in your budget for replacement windows.

Window Disposal

When you work with a certified window contractor, they will take care of disposing of all the excess materials that accumulate throughout the window installation project. If you are installing the windows yourself, you will have to figure out how much it is going to cost you to dispose of the old windows and excess. If your old windows are in good shape, you can sell them or donate them to Habit for Humanity or another charity.

If they’re in poor shape, you will likely have to pay to dispose of them. Figure out what disposal costs are in your area and budget between $50 and $400 to get rid of all the materials that are left over at the end of the replacement window project.

Window Tax Credits & Rebates

You might be surprised by all of the available local window rebates and credits that will help you get money back on your window replacement. To find out if there are window rebates in your area, get in touch with your local utility company. Many are offering rebates to customers who have Energy Star or energy efficient windows professionally installed in their homes. You might find out that you qualify for $200 per window or more in rebates. Many times these companies will provide a per window rebate up to a specific amount.

In addition to local utility rebates, there are also plenty of government incentives for homeowners who make energy efficient home improvements. According to, Energy Star windows reduce utility monthly utility bills by a national average of 12%. You can check out the DSIRE (Database of State Incentives for Renewables and Efficiency) to search for energy-efficient incentives in your state.

 Insurance for New Windows

When you buy new windows from a big box store like Lowes or Home Depot, you’ll undoubtedly be offered an insurance plan on top of the window warranty that comes with the replacement windows. Many times this insurance plan will help fix damaged windows that aren’t covered under the standard manufacturer’s warranty. If you want the added protection so that you don’t have to worry about saving for future window problems, factor in the cost of that insurance into the overall price as well.

New Window Financing

If you’re planning to have many windows replaced at once, you’ll probably need to finance your window replacement project. Even at the low end of a replacement window cost, you should expect to pay between $450 and $500 per window. If that kind of spending isn’t realistic for you all at once, look into the many available financing options:

  • Home Improvement and Home Equity Loans– Many home improvement loans are available for purchases like new replacement windows, flooring, roofing, or other projects that will improve the value of your home. Talk to your local bank or credit union to find out if you qualify. If you’ve been paying off your home for a long time and you have some serious equity in it—usually between 40 and 60 percent at a minimum—you might be able to take out a second loan relying on the equity that you already have.
  • Mortgage Increase– In some instances you can get a higher mortgage amount than what you need to buy the home itself, and that amount can be used to make improvements to the home. If you have a significant down payment, as well as some window contractor bids and before-and-after appraisals for your project, you might get the bump up that you need to cover at least part of the home improvement from your mortgage.

Once you’ve added the cost of the new windows, labor and disposal fee, simply subtract any tax breaks or rebates. Then you’ll be able to determine exactly what it will cost for your home’s new windows, and you’ll be a better informed homeowner, too.
