Is it normal to have bubbles after car window tinting?

It is normal to have bubbles after car window tinting, and bubbles mostly occur because the glass was not cleaned thoroughly during the process. Car window tinting (Autotintfilm) involves applying a thin film to the front and rear windshields, side windows, and sunroof of a vehicle. This film is also known as solar film or heat-insulating film. The primary functions of car window tinting are to block ultraviolet rays, reduce heat, prevent injuries from shattered glass, minimize glare, and, due to the one-way visibility of the film, protect personal privacy. Additionally, car window tinting can reduce damage to interior items and passengers caused by UV exposure, lower the interior temperature through physical reflection, decrease the use of air conditioning, and improve fuel efficiency.
I've been in the car window tinting business for years. Small bubbles after installation are actually quite common—mainly caused by trapped moisture from the application spray that hasn't fully evaporated, especially in humid weather. These usually disappear on their own within a few days. But don't take it lightly: if there are numerous/large bubbles or they persist beyond 3-5 days, it likely indicates installation issues like uneven film application, trapped dust, or substandard film quality. The proper approach is to consult a professional. For the first 48 hours post-installation, avoid rolling down windows and direct sunlight to allow gradual moisture evaporation. Never attempt to press down major bubbles yourself (risk of film scratches)—contact the installer immediately for rework. Quality tinting lies in the details. Opt for premium films like ceramic or security-grade tints—they're more durable and less prone to defects.
