Window tinting typically lasts anywhere from 5 to 10 years, depending on the quality of the film, installation, and how well it's maintained. Premium tints can last even longer. Over time, you might notice fading, bubbling, or peeling, which signals it’s time for replacement. Proper care, such as avoiding harsh cleaners and direct scraping, helps extend its life. For long-lasting results, professional window tinting is highly recommended.
