Should I Remove The Trim Before Putting In Shutters? The answer will depend on your personal taste. If you want to keep your existing trim, we can build your shutters to match your current trim. If you like our shutter frames better, then you can remove the trim—but it’s not a requirement. If you’re trying to go trimless or replace your trim, your Sunburst installer can help you find the right shutter to match the vision you have in mind for your windows.
