Do I Need To Remove The Trim Before Installing Shutters? That’s up to your personal style. If you want to keep your trim in place, 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 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 right shutter to match your perfect vision.
