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 the trim you already have, we can build custom shutters to fit with your current trim. If you prefer our shutter frames, then you can take out the existing trim—but it’s not a necessity. If you’re trying to go trimless or replace your trim, your Sunburst installer can help you choose the best option to fit what you have in mind for your space.
