Storm Window Cost for Install & Replacement

Storm window prices are lower than replacement window prices, and storm windows significantly reduce heat transfer and energy costs by adding another pane of glass and an insulating air pocket. As a result, aluminum and vinyl storm windows pay for themselves in less than five years, especially in climates with extreme high or low temperatures. Wood storms are pricier, so it takes longer to recoup their cost through lower utility bills.

This storm windows cost guide includes pricing for the features and options available. Only genuine storm windows with glass are included. To compare costs to replacement windows in the style you prefer, see our window cost guides for Single-Hung, Double-Hung, Casement and other window types.

Storm Window Features and Options

Storm windows can be installed on the inside or outside of the window. While some brands are made for one or the other option, leading brands of storm windows can be installed inside or outside for your convenience.

There are two ways to buy storm windows:

Standard storm windows are pre-made to a range of sizes, almost exclusively in aluminum or vinyl. Most have an expander on the frame that adjusts for a tight fit. Colors and options are limited. These windows are widely available online and at Menards, Lowes, and other home improvement/building supply stores.

Custom storm windows are not manufactured until a customer places an order with the exact window measurements along with the features and options they prefer. A more exact fit is guaranteed, though the cost of the windows is significantly higher than the price of standard-sized storm windows. Custom storm windows in aluminum, vinyl and wood can be ordered at home improvement/building supply companies, or you can work with a local window and door company. They are typically delivered in three to six weeks, so plan ahead of cold weather!

Here’s an overview of your storm window features and options:

  • Window types: Single-hung, double-hung, sliding/gliding and fixed/picture storm windows are made.
  • Two-track and three-track: Two-track storm windows have a fixed upper pane and lower screen. The lower pane can be raised and lowered for ventilation. Three-track or triple-track storm windows have movable upper and lower panes and a movable screen too. Two-track and three-track models are made in vertical and horizontal styles. Fixed/picture storm windows have no movable parts.
  • Materials: In order from cheapest to most expensive, storm windows are available in aluminum ($-$$), vinyl ($-$$$) and wood ($$-$$$$). Of those, aluminum has the worst insulating properties by far, but it is nearly maintenance-free. Wood offers slightly better insulation than vinyl, though it requires much higher maintenance unless it is a vinyl-clad wood frame ($$$$).
  • Glass: Low E (emissivity) insulating glass is common. Clear, tinted and textured glass is found in standard windows; you’ve got even more options with custom windows.
  • Colors: Aluminum and vinyl are offered in up to four colors from most manufacturers. Wood storms are produced in many finishes and vinyl-cladding colors.

Custom storm windows can be made in any size. Here are the standard or off-the-shelf sizes:

  • Vertical-opening windows: Width – 24” to 42” / Height – 39” to 63”
  • Horizontal-opening windows: Width – 36” to 60” / Height – 32” to 60”

Pros and Cons of Storm Windows

On the plus side, storm windows reduce energy use and cost, so make your home greener and more affordable to maintain. Most are both attractive and durable, and give you the option of installing them on the interior side of the existing window or the exterior. They can be installed permanently, though fixed windows need to be removed for ventilation if installed over windows that open. Storm windows can serve as more affordable replacement windows, but this is not a good idea in either hot or cold climates. The negative side to storm windows is that they cost more than plastic film, but are also much more efficient. Also, you must raise or slide two sashes/panes to get ventilation, rather than just one, but this is a minor inconvenience.

Factors that Affect Storm Window Costs

Frame material, size and whether the windows are standard sizes or must be custom built are the major cost factors. There are two other considerations.

Window companies offer better pricing when they are less busy. This might be early spring and late fall in cold climates and winter everywhere else.

Finally, who installs your storm windows affects cost. Storms are much easier to install than regular windows, so DIY installation is a good option for people with moderate skills. If you choose professional installation, request written estimates from several storm window contractors in your area, and let them know they’re competing for the job. This ensures getting the best pricing possible.
