Should I Remove The Trim Before Putting In Shutters? Whether or not to remove the trim depends on your personal taste. If you want to keep your trim in place, we’re able to build custom shutters to fit with your current trim. If you like our shutter frames better, then removing trim is fine—but it’s not a necessity. If you’re trying to go trimless or replace your trim, your Sunburst installer can help you pick the right option to fit the vision you have in mind for your windows.
