Cellular PVC Window Boxes: Rot-Proof, Self-Watering & Custom

Why Cellular PVC?

Cellular PVC mimics wood’s look and density but won’t rot, split, warp, or attract insects. It’s the same material used in modern exterior trim, garage door frames, and spa surrounds—proven in ground-contact and wet environments.

Estate Collection – Handcrafted Quality

• Built one-by-one from 4×8 ft sheets by craftsmen.
• 15 standard sizes; custom dimensions available.
• Rot-proof, maintenance-free, paintable (holds paint 3× longer than wood).

Self-Watering Window Boxes

Integrated reservoirs wick water to roots for up to 3 weeks outdoors (3 months indoors). Each plant takes only what it needs—perfect for mixed moisture preferences. Drop-in reservoir kits retrofit existing boxes.

Benefits Summary

• Zero rot, warp, or insect damage.
• Self-watering cuts chore time dramatically.
• Custom sizes & colors for perfect architectural fit.
• Lightweight yet rigid—easy to mount on any facade.
