Why Not to Install Window Film Yourself: Five Reasons

January 29, 2025 by Carol S Leave a Comment

Why wouldn’t you want to install your own window film? Let us count the ways!

What could possibly go wrong if you install your own window film?

You might have woken up with the idea of installing your own window film. Maybe the idea came to you in a dream and you thought How hard could it be? We’ve seen plenty of window film projects gone wrong, and are often called in to fix those do-it-yourself jobs. So before you do it yourself, here are some reasons you’d maybe want to call us instead!

Wrong measurements

You’ve all heard that old saying in construction Measure Twice, Cut Once, right? Well, lots of people tend to eyeball it with window film. Or even if they want to measure their windows, they’ve lost their measuring tape! If that sounds like you, maybe read Ten Ways to Get Organized Right Now. And get back to us later. Window film is not something where you want to guess about how big your window is. And with more complex installations, measuring is even more important!

Bubbling Film

You’ve seen those big air bubbles on car window film installations, haven’t you? You’re stuck in traffic, and you look over and–there it is–an assault on your eyes and brain! Don’t be tempted to yell out the window, “But WHYYYYY???” because you just don’t know who’s armed these days. And chances are, the driver already knows how horrible their windows look, without the reminder. Anyway, the point is don’t let bubbling film happen to you!

Wrinkles

We’re not talking about crow’s feet around your eyes. We’re talking about wrinkles in your window film! Ugh. Another reason not to take window film into your own hands. Once there are wrinkles, there is little you can do but start over. And let the cussing begin.

Warranty issues

Did you know that when you install your own window film you might not get the benefit of the warranty? Many major brands issue a warranty when a professional installs the window film. For example, 3M issues a warranty, but the film needs to be installed correctly.

Damage potential

Do you have a place to store that beautiful window film while you’re getting ready to install it? Have you trained your cats and your crazy border collie not to jump all over and scratch it? If the answer is no, then you might want a pro doing the install for you!

Falls and injuries

As the picture above illustrates, falling happens more often that you might realize. And you might not have everything you need–such as the correct ladder. (Yes, we know this is reason #6, but who’s counting?) And if you’re determined to do it yourself, the CDC has plenty of info about Ladder Safety. There’s even a Ladder Safety App (scroll down).

We make it easy!
