Auto glass installers repair or replace damaged windshields and windows in motor vehicles.

Auto glass installers inspect the cracks and chips in the glass and determine if it can be repaired. They remove old glass to replace windows. They dismantle door panels and window frames to access the cracked glass. Installers clean or replace window frames to prepare the vehicle for new glass. They may repair the motors that raise and lower windows.

Installers sometimes cut glass to fit. They measure the window frame, select the proper type of glass, and transfer the measurements to the new glass. They use a straight edge and a glasscutter to fit the glass to the frame. They may shape or smooth the edges of the cut glass by holding the glass against an abrasive belt.

Installers transfer finished glass to the vehicle. They often use suction cups to place the glass in position. They secure the glass using:

• Special tape
• Sealants
• Adhesives
• Bolts
• Rubber gaskets
• Metal clips
• Molding

Installers reassemble door panels and other trim pieces after glass is installed.

Some auto glass installers repair glass rather than install new glass. They force a liquid resin into the crack. They shine ultraviolet light on the resin to harden it.

Auto glass installers may work in shops or travel to customers' locations. Installers often write reports for customers and insurance companies.
