Most window installation and repair companies can handle putting tint film over your existing windows, but it’s best to hire a company that specializes in window tinting. This decision will result in the best application for the cleanest look, and it usually means you’ll get a better professional opinion about the type of tint and tint level that makes the most sense for your home and personal preferences.

Applying window security film yourself is possible, but we don’t recommend it. This task is simple in theory, but getting the product to sit on your windows evenly and without bubbles underneath is challenging for DIYers who lack the necessary experience and tools. You might save money on labor by applying it yourself, but you might also end up with a film that doesn’t look appealing, prompting you to start over and spend the money on a professional installation anyway. Plus, most window film manufacturers will void your warranty if you install the product yourself.

Tinting your windows will make your house darker since it will prevent some sunlight from getting inside. While you can choose a window film that is on the lighter side, there will still be reduced sunlight. If natural light is important to you, tinted windows might not be the best choice for your home.

Some frosted glass sprays can handle the outdoors, but most of them aren't built for it. Sprays made for exterior use will say so clearly on the label. Anything marked “interior use only” can't hold up against rain, UV exposure, or changing temperatures without peeling, fading, or yellowing. Outdoor-rated sprays are typically more durable, but even then, proper prep and application matter. Before spraying anything outside, double-check the product instructions. If it doesn’t specifically mention exterior use, skip it.
