Do I Need To Remove The Trim Before Installing Shutters? Whether or not to remove the trim depends on your own taste. If you want to keep your existing trim, we can build custom shutters to complement your current trim. If you like our shutter frames better, then you can take out the existing trim—but it’s not a requirement. If you’re trying to go trimless or replace your trim, your Sunburst installer can help you find the best option to fit the vision you have in mind for your windows.
