Home window installation and replacement is part of the home improvement industry. New homes are generally built with custom windows and doors. However, many homeowners want to replace their windows. They may choose to go from single pane to double pane windows. They may also choose to install French sliding doors or windows to allow entry to and from a patio or outdoor area. It is also common to replace older wooden frames, prone to rot, with new plastic or metal. A skylight might be added to a dark room. These may be a specific improvement project or part of a larger one. Window contractors may also install standard, wooden doors or storm doors.
The simple replacement of single windows and panes is also important, as is repair of damaged and rotten frames. Older houses may require custom replacement for a bay window or to preserve the look of old leaded glass. Stained glass tends to be created by specialists and is still often made by artisans working mostly by hand. Modern stained glass is often considered to be art work.
Automotive window replacement is also important. Car and truck windows are designed to be almost unbreakable. They are also not flat, like house windows, but curved. In many cases, cars are made with factory tinted windows. Tinting is also sometimes added in the form of a film or tape. Most automotive windows are tinted lightly, with darker tints sometimes being used. Dark tints are common on limousines to ensure privacy.
Commercial window cleaners are important employers, especially in large cities. Although residential homeowners sometimes hire window cleaners, most work on large buildings, often suspended at a considerable height. Although it is technically janitorial labor, it requires a certain level of skill to ensure the windows are cleaned right.
