Window repairers and installers possess similar skills. However, in some cases, repairers may be asked to restore antique windows. Most modern windows have vinyl or PVC frames, but wood may be used for authenticity. Most companies specialize in either homes or commercial buildings.
Repairs may involve replacing a single broken pane or an entire window. Workers may also install storm shutters or insect screens on existing windows, or repair the fine details in design. Some may also repair doors. Insulated inserts are commonly added, as are security features. Workers need to be capable of manual labor, but also aware enough to be comfortable with a range of duties.
Contractors may purchase a variety of items including tools, frames and plate glass. They may purchase pre-sized panes or cut glass down to the appropriate size.
Auto window repairs are generally done at repair shops, although there are some specialists. Some companies handle both auto and building windows. As auto glass is laminated and tempered, it breaks less often than home windows. However, the slightest crack in a windshield can be a potential accident. Workers need to keep glass on hand that is suitable for multiple makes and models of cars. They need to be aware of the customer's wishes in terms of custom tints. Sunroofs are often deeply tinted. In some cases, they may also install bullet resistant glass. Most of their job, however, is to replace a window that has become broken in an accident.
Glass repair companies may also repair other glass features such as display cases.
