5 Window Film Installation Prep Tips

So, you’ve decided to install window film to improve the comfort of your home. Maybe it’s to tame the sun, control the glare, or block harmful UV rays. Or maybe you want to prevent fading, save energy, or add some daytime privacy. Whatever the reason, installing window film yourself is an easy and money-saving way to upgrade your existing windows. To ensure your project’s success, we’ve got some tips on how to prep for window film installation.

Alexander Graham Bell said it best, “before anything else, preparation is the key to success”. It’s not glamorous or exciting, but proper prepping for your window film installation will make the job go smoother and easier.

Tip #1:  Clean the outside of your windows prior to window film installation.

When installing window film, you want a clean interior surface to mount the film on and the best way to tell if your windows are ready for film is if both sides are clean. If the exterior of your windows are dirty, it will be difficult to tell if the inside is clean. Plus your film will look much better on clean windows.

Tip #2: Remove any curtains or shades that make it difficult to get at the glass.

This is another thing you can do ahead of time so when your film arrives, you are ready to focus on the installation and not removing window treatments. Some blinds and shades roll or fold up enough that they don’t need to be removed, but if anything overlaps the glass, its best to temporarily remove it.

Tip #3: Make sure you have plenty of space around the windows to maneuver.

if you have heavy furniture in front of windows that prevents you from getting access to them (think a piano or sofa), make a plan for how you will move those pieces prior to installation day. You may need to enlist the help of a strong friend to help you clear the path for film installation.

Tip #4: Give the room a good vacuuming prior to window film installation.

Dust particles or animal hair can become airborne as you are moving around the project site and could potentially stick to exposed film while you are installing it. It’s a good idea to remove as much dust, dirt, and pet hair from a room as possible. We recommend giving it a good dusting and vacuuming before you begin the window film installation.

Tip #5: Clean the inside of your windows.

If it’s been a while since you’ve washed your windows, it might be a good idea to clean them prior to installation day. This gives you enough time to really ensure that the glass is clean before you install your film. Older windows can have dirt build-up and sometimes paint on the glass near the frame that will need to be removed. If you ever tape things to the window, there can be residual adhesive stuck to the glass. Follow our pro window cleaning steps. Clean your windows thoroughly with a razor blade scraper, window cleaner, and squeegee. Then wipe them dry with a low-lint cloth or paper towel.

Sometimes the sill that’s exposed to the outside can become quite dirty. If this is the case, take the time to clean up as much dirt as possible, first with a vacuum fitted with a brush attachment to pick up loose dirt and debris, and then with hot, soapy water. The less dirt that is on or around the window, the less chance there is of film contamination.

Have a great installation!
