A storm window is your first line of defense against cold air infiltration. Aluminum storm windows are a good choice to replace old wooden storms and screens, and they’re widely available online, at building suppliers, home centers and window replacement companies. The windows, available in standard and custom sizes, are designed with glass and screen inserts that slide in and out of position in channels along the sides of the frame. If you want to lower your energy bills and keep cold drafts at bay, an aluminum storm window is a worthwhile investment.
How much does it cost to install a storm window? A carpenter will replace a 3-foot-by-5-foot aluminum storm window for $186 which includes the labor and material, but you can buy the unit for $115 and install it yourself, pocketing a 38 percent saving. If you do it yourself and are replacing an existing storm window with a new one, allow time to remove the old one and make any repairs or adjustments to the window frame before installing the new one.
When you’re investing in new storm windows for the whole house, you’re better off hiring a window replacement company because there’s an economy of scale a do-it-yourselfer can’t compete with.

There’s no better time to paint the exterior of a window than before installing a new storm window. Plan the job to include scraping, caulking and painting and allow more time to complete the job. When the paint has dried thoroughly, install the new storm window.
