Will I be able to keep my old window trim if I put in shutters? Yes! There’s rarely a need to take out or do work on your existing 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 existing window trim. If your windows have no trim, we also have frame styles available to install right onto the drywall around your window to secure your beautiful new shutters to your window opening.Your installation team will measure each of your individual windows during your complimentary in-home consultation to ensure that your window trim is beautifully complemented by the frame of your new window treatment.
