Glass windows & doors are guaranteed for up to 20 years. However, it is important to note that the warranty does not cover any damage caused by normal weathering. This means that the glass will not be covered if it is exposed to UV or external/internal temperature changes. In addition, the warranty does not cover the labor cost of removing and reinstalling damaged pane glass.

Many window replacement companies offer limited lifetime warranties. These warranties cover any defective parts and may not cover labor costs. Different manufacturers have different product repair procedures.

Warranties for glass windows & doors vary depending on the type of glass used. For example, a insulating glass unit will be covered for up to 20 years. Glass over 60 square feet is usually guaranteed for 10 years. The warranty for non-glass parts, such as door hardware, is 10 years.

After the housing bubble burst, many window and door companies were forced to close, leaving customers unable to make warranty claims. Some have even handled claims for products they did not produce themselves. But the question of who will be responsible for warranty claims is a complicated one. The best way to find a warranty on glass windows & doors is to contact the manufacturer or company that purchased them.

Warranties for glass and hardware should cover all parts of the window, not just the glass. It should also cover the hardware and window screens. If any of these parts break, you may face unexpected repair costs. Also, the warranty should cover the installation. Improper installation will result in a weak seal or failure.
Some manufacturers offer lifetime warranties on their products. However, these guarantees are usually complex documents covering the details of the guarantee. Before installing new glass windows & doors, be sure to read the warranty carefully and understand all coverage details. If you are unsure, consult the manufacturer before installing a new product.
