Do I Need To Remove My Trim Before Installing Shutters? That’s up to your personal style. If you want to keep the trim you already have, we can build your shutters to fit with your current trim. If you prefer our shutter frames, then you can remove the trim—but it’s not a necessity. If you’re trying to go trimless or replace your trim, we can help you find the right shutter to fit the vision you have in mind for your windows.
