Do I Need To Remove The Trim Before Putting In Shutters? The answer will depend on your personal taste. If you want to keep your existing trim, we can build your shutters to match your current trim. If you prefer our shutter frames, then you can remove the trim—but it’s not a requirement. If you want to go without trim or replace your trim, your Sunburst installer can help you find the right shutter to match the vision you have in mind for your windows.
