Love the look of traditional wood window boxes but not the upkeep? Composite PVC Window Boxes offer the classic charm of wood without the worries of splintering, rotting, warping, or fading. Crafted from thick, durable PVC sheets in a crisp eggshell white, these window boxes are built to last and maintain their beauty year after year—with virtually no maintenance required.

Just like wood, our PVC window boxes are cut, mitered, and trimmed for a handcrafted look, and many styles come with decorative brackets to add that perfect finishing touch. Designed with both form and function in mind, several of our styles feature a hidden cleat mounting system that makes installation under windows, along fences, or on walls quick and secure. Plus, the cleat makes it easy to remove and re-install your box for replanting or seasonal updates.

Want to match your home's trim or add a pop of color? PVC can be painted to suit your style, and custom sizes are available to ensure the perfect fit for your space.

Enjoy timeless curb appeal without the maintenance—our composite PVC window boxes blend traditional beauty with modern durability.
