Get matched with top window pros in Fairview Heights, IL

The average lifespan for a casement window is around 20 years, but some higher-end casement windows with more durable frame materials can last up to around 40 years before you need to replace them. You’ll need to carry out routine maintenance and window cleaning—and, on occasion, casement window restoration—to extend the lifespan of your casement windows. But they tend to wear more slowly than windows with sliding sashes because the weatherstripping sees minimal friction.

If the existing frame around the window sash is completely structurally sound, it's possible to save money by swapping out the sash for a new one instead of getting a new window. Keep in mind that it will be necessary to find a new sash that perfectly matches your existing window structure. In general, consulting a window pro to help you find the right match is the best way to ensure you're doing this project correctly.

Finding a reputable contractor for an egress window installation involves researching and vetting potential candidates. Start by searching for local professionals, reading customer reviews, and checking their websites for a portfolio of their work.

Once you have a shortlist, ask the following questions to ensure they are qualified:

• Are you licensed and insured?

• How do you handle payment?

When specifying window sizes, manufacturers use a standard four-digit code system. The first two numbers represent window width, and the last two represent window height. For example, a window with a code of 2917 has dimensions of 2 feet, 9 inches wide by 1 foot, 7 inches high. Windows with even dimensions include zeros as placeholders. For example, a window that is 5 feet wide by 2 feet high would have a code of 5020.
