Should I Remove The Trim Before Putting In Shutters? That’s up to your personal taste. If you want to keep your existing trim, we’re able to build custom shutters to match your current trim. If you like our shutter frames better, then removing trim is fine—but it’s not a necessity. If you want to go without trim or replace your trim, we’ll help you choose the best shutter to fit what you have in mind for your space.
