Am I able to keep my existing window trim if I install shutters? Yes! There’s rarely a need to remove or make alterations to your current window trim when putting in new plantation shutters. Natural Ovation wood shutters and patented Polywood shutters are offered in a variety of frame styles to fit naturally into your current window trim. If your windows have no trim, we also have frame styles available to install directly onto the drywall around your window to fix your beautiful new shutters to your window opening.Your shutter installer will measure each of your house’s windows during your complimentary design consultation to make sure that your window trim is tastefully complemented by the frame of your new shutters.
