Home window tinting costs $5 to $8 per square foot with labor or $300 to $700 total, depending on the following factors:

• The number of windows
• The shape of the windows
• Whether they're on the first or second story

Tinting your windows is cheaper and simpler than buying coverings. Blinds, curtains, and shutters are attractive but need to be closed and opened manually every day.

Tinting your windows is worth it if you value privacy or want to block sunlight in your home. Window tinting reduces the following:

• Sunlight by 80% to 90%
• Heat by up to 10 to 20 degrees
• Glare by 90% to 100%
• UV rays by up to 99%

Professional window tinting installation takes 10 to 20 minutes per window, depending on the size, location, and accessibility. A single first-story window takes less time to tint than multiple windows that are large or on the second story.

Window tint lasts 5 to 30 years, depending on the window location and quality of the film. West-facing windows receive more hot, afternoon sun and the tint may not last as long as it does on windows in shadier spots. Some companies offer warranties that cover the tint as long as you own your home.

The shade of your tint will depend on the room and the reason you want to tint your windows. To block UV rays but still allow a moderate amount of light inside, a 35% to 50% tint is best.

A 10% to 30% tint is best for privacy and security because it will only allow a small fraction of light inside. Be aware, however, that tinted windows are easier to see through at night when lights are shining from inside the house.

Some hardware stores, such as Home Depot and Lowe's, sell do-it-yourself window tinting kits. However, professional tinting is more likely to be seamless and discreet. Applying it yourself may result in bubbles or crooked tinting.
