Does it feel like your window film is failing? While window film can be an efficient option for boosting privacy, protecting rooms from UV damage, and keeping your home's interior cool, it's susceptible to some common problems. If you're experiencing one of these problems, this guide will help you find the right fix.

1. Bubbling Window Film

Window film should be smooth and fully flush against your window. In general, it takes between 30 and 80 days for window tint to fully bond with a window. This is why a window that looked "perfect" immediately after installation may begin to bubble after a few months. Bubbling is among the most common window tint problems because no home is ever really free of dust. While very minor, nearly invisible bubbling is fairly common; extreme bubbling is cause for concern.

The Fix

Unfortunately, the only way to get rid of bubbles on window film is to redo the installation. If you used a professional installer, contact them to let them know that you believe the installation was faulty. It's possible that the team did not properly clean the window surface prior to installation. If this were a DIY project, you may have failed to properly clean the window prior to following the steps for applying window film.

2. Peeling

Properly installed window film should remain fully intact. If you've noticed window film lifting away from the glass or curling at the edges, it's only a matter of time before the film detaches completely from the window.

The Fix

If peeling appears minor, try using a small amount of adhesive spray for window film to get the film to stick again. If there is extreme curling that is making it difficult to get the edges to stay in place, a more powerful adhesive available from a professional window tinter may be needed.

3. Water Spots

Are you noticing unsightly streaks or water spots on the surface of your window film? You may be confused about why your film is stained and streaked when you've been so consistent with washing your windows. The answer may be that you have hard water that contains heavy mineral concentrations.

The Fix

Stop using untreated tap water to clean your windows. Use distilled bottled water instead. To remove existing spots left behind by hard water, gently clean the window using a solution made of diluted vinegar and distilled water. To prevent scratches, only use a soft microfiber cloth. Drying the surface of the window with a soft, dry towel can also help to prevent streaking.

When to Call a Pro

If your window tints are clearly peeling off or bubbling to the point of being an eyesore, it's time to get some help from a local home window tinting company near you. With most home window tints designed to last five to 15 years, it may be time to consider low-e glass vs window film or discover new types of window tint if yours are on the older side.

Frequently Asked Questions

On average, the cost to tint your home's windows can range from $2 to $100 per square foot, with all labor and materials accounted for. That places the project cost anywhere from $200 to $350 for one to two windows to $4,124 to $4,747 for 13 to 15 windows. However, most homeowners only tint windows located in areas of a home where strong direct sunlight and a lack of privacy are concerns.

Tinted window films for houses are usually made from a micro-thin sheet of thermoplastic resin called polyethylene terephthalate (PET) that offers the strength and flexibility needed when fitting film to a window. Homeowners looking for a solution that insulates a window without blocking light from a home should investigate low-e glass vs. window film.
