Overview of Storm Window Installation
A storm window is a window that can be installed on either the interior or exterior of an existing window to conserve a home’s energy by adding an additional pane of glass. Storm windows are especially popular for older homes that have drafty, single-pane windows, because they provide another layer of insulation between your home and the outdoors.
Single-hung storm windows or pricier casement windows still costs more than standard storm windows, so many homeowners use storm windows as a budget-friendly way to get the benefits of a brand new window without having to pay the full price for one.
Storm Window Styles
It wasn’t long ago that storm windows were purely functional, a layer of glass over the existing windows, with little regard to style. And the vast majority did not open. That’s all changed for the better.
Storm windows are available in several different types, including single or double-hung, sliding, and fixed storm windows. Those that open are called two-track windows. Most two-track models have a fixed outer track or plane with a fixed pane in the upper half and a screen in the lower half.
The inner track or plane features moving sashes, either double-hung with two moving sashes or a single-hung with just a lower moving sash. Triple-track storms are also produced. They have an extra layer of protection and moving sashes for ventilation. Lowe’s has put together a useful overview of the various types.
Buying Tip: If you choose to get a fixed storm window, you’ll have to remove the storm window any time you want to open the old window for ventilation. So, if you plan to leave the storm windows in most or all of the year, consider types that open.
Three materials are used for storm windows: aluminum, vinyl, and wood.
Aluminum is the least expensive material, but it is also the least energy efficient of the three because heat easily passes through it.
Vinyl is the most popular storm window material, because it is affordable and energy efficient. Vinyl storm windows are energy efficient, and come in a wide variety of colors.
Wood is the most expensive material for storm windows, but it is also the most beautiful and ecofriendly. Most have bare exteriors – not clad in vinyl or aluminum – and are best suited for use on historic homes where maintaining a classic appearance is expected.

Storm Window Cost Factors
How much does a storm window cost, including installation? Below is a list of cost factors that will determine the total expense of your project.
- Window Style – The style of window you choose will have a big effect on the total cost of your project. Fixed windows are the least expensive storm window style, but they don’t have the benefit of opening and closing. Single and double-hung storm windows are the next cheapest option, followed by sliding windows.
- Custom vs. Off The Shelf – Buying storm windows off the shelf is the least expensive way to go. You can find storm windows in the most common window sizes at most home improvement stores. Some homeowners choose to order custom storm windows in order to ensure a tighter fit, or to accommodate unusually-sized windows.
- Window Material – The window material you choose will determine how expensive your storm window unit will cost. If you have a tighter budget, look into aluminum or vinyl storm windows. If you are aiming for a classic, elegant look, check out wood storm windows. Many wood storms are custom-made, and that can double the cost vs vinyl – easily.
- Glass Type – Many storm windows come with low-E glass, but some don’t. If you are planning to choose a special glass type for your storm window, make sure that you are prepared to pay a little extra for it.
- Number of Tracks – Double and triple track windows cost more than single track versions due to added framing and glass.
- Professional Installation vs. DIY – Hiring a professional to install your storm window is going to cost more than doing the installation yourself. Make sure to budget for installation costs if you’re planning to hire an installer.
- Number of Windows – Pro installation cost per window goes down slightly as the number of windows rises.

DIY or Hire a Pro?
How much can you save installing your storm windows? We put the price tag at $50 to $125 per window. Homewyse estimates $40 to $100 per window, and that’s about right, with cost going down about $6 to $15 per window when the number of storms installed rises from 2 to 10 or more.

Storm windows are generally a great DIY project. The labor time and effort is minimal, and you only need basic hand tools to get the job done.
However, if you are planning to install a storm window on the exterior of a second or third story window, it’s probably safer to hire a pro. Don’t risk your well-being for the sake of a storm window!
Use your best judgement to figure out if your storm window project is a good DIY for you or not.
