Quick Answer
DIY window film costs less upfront — often $1–$4 per square foot for store-bought film — but typically uses lower-grade film and often ends up with bubbles, dust, creases, or peeling edges. Professional installation ($5–$12 per square foot in LA) uses higher-performance film, includes a manufacturer warranty, and ensures the film is compatible with your glass, which matters most on dual-pane windows.
