Storm Windows
In colder climates, storm windows (storms) reduce the heating load and prevent damage from
condensation on window interiors. Storms also protect the windows from extreme weather. The
damaged window in Figure 8-2 wasn’t protected by a storm window. The sash joints are weak and need
to be reinforced; the glazing putty has to be replaced; the swollen, rough wood has to be sanded
smooth so the window will open and close without sticking; and the window needs paint. Most of this
work could have been avoided if a storm window had been installed during winter months.

When evaluating windows, note whether the house has removable storms and screens. Most homes
built in cold climates between 1920 and 1980 have (or had) storm windows. Newer homes usually have
insulated (double pane) glazing that offers weather protection similar to storm windows.

Galvanized self-storing storm-and-screen windows were introduced in the 1940s. Aluminum storms and
screens became popular in the 1950s. Older aluminum storms will be oxidized and pitted and rubber
glazing strips will be deteriorated. If you elect to replace windows, storms may not be needed. If you
plan to repair windows, storms will be required in colder climates. It’s usually better to replace (rather
than repair) deteriorated storms, especially for standard size windows. Most storm windows have a 2”
skirt that can be trimmed off to make minor adjustments in width and height. Storms can be custom
fabricated for odd-size windows at moderate cost. For a little extra money, consider high-performance
storms with Low-E glass.

Repair of Existing Wood Windows
Repair is easy when the only problem with a wood window is minor decay. A coat of water-repellent
preservative on the exterior will stop further deterioration. This is a three-step process:

1. Use a heat gun or paint stripper to remove the existing paint.
2. Brush on preservative.
3. Repaint the window.

Paint can’t be used over some types of wood preservative, so be sure to select a paintable preservative.

Next, consider aesthetics. This is especially important on older or historic homes. If you install modern
windows, the house will have a new look. Is that new look going to be in harmony with the exterior trim?
With the siding? With the roofing? With other windows in the house? If just a few windows need
replacing, can you replace just those few without creating an eyesore? In such cases, repairing a
window may be a much better choice than replacement, both in the money saved and in the
preservation a consistent style for the home.
