Do I Need To Remove The Trim Before Installing Shutters? Whether or not to remove the trim depends on your personal taste. If you want to keep your existing trim, we can build your shutters to match your current trim. If you like our shutter frames better, then you can remove the trim—but it is not a requirement for shutters. If you want to go without trim or replace your trim, your Sunburst installer can help you pick the best shutter to fit the vision you have in mind for your windows.
