Egress Windows

Egress windows are an essential aspect of emergency preparedness included in the building code for your family’s safety. While emergency exit windows may seem like a simple thing we take for granted, they could save your life one day.

At Lake Washington Windows and Doors, we’re proud to improve the safety and comfort of families throughout the Seattle area with our Egress window installation service.

What are egress windows?

An egress window is a regular window designed to provide a means of emergency escape. The word egress means ‘to emerge’ or ‘a path out.’ Therefore, egress window installation is required in any room made for sleeping. These windows must meet certain requirements to function as a means of escape.

How many egress windows are required in a basement?

Usually 1 egress window minimum is required for each bedroom located in the basement. Not every basement window needs to be installed with a means for escape. Throughout Washington and Seattle, building code requires each basement to have one window of a certain size that meets emergency requirements.

One of the best ways to improve the value of any home is to add a bedroom or additional living space. Many homes have unused basements perfect for a bedroom or living suite conversion. If you plan to convert your basement into a living space, installing basement egress windows is a crucial security measure.
