Cornerstone Window Parts


History of Cornerstone Windows

Cornerstone Windows was founded in 1994 and was initially based in Pennsylvania. The company specialized in high-quality windows that were designed with the environment in mind. Cornerstone Windows was known for its use of locally sourced materials and energy-efficient designs. The company was acquired by a larger window manufacturer in 2014, but many buildings still have Cornerstone Windows installed.

Types of Parts Needed

The most commonly replaced parts for Cornerstone Windows are sash locks, tilt latches, and window balances. Sash locks keep the window securely closed while tilt latches allow the window to be tilted inwards for easy cleaning. A window balance is a system of springs or weights that helps to keep the window in place when it is opened. In some cases, entire window sashes may also need to be replaced.
