PVC Window Boxes
Our cellular PVC window boxes combine traditional aesthetics with modern durability. The material resists cracking and warping while maintaining a natural wood-like appearance. Available in 12 standard styles and 16-foot custom lengths, these boxes feature optional self-watering reservoirs and lifetime warranties. The matte finish accepts paint for customized color matching with home exteriors.
Self-Watering Planters
Patented reservoir systems maintain optimal soil moisture through capillary action. This technology reduces manual watering requirements by up to 70% while preventing root rot. Available as integrated units or retrofit kits, these systems work with PVC, cedar, and metal planter materials for both window and ground applications.
Cedar Shutters
Premium western red cedar shutters feature tongue-and-groove construction for weather resistance. Available in standard and custom sizes with multiple louver configurations, these shutters combine traditional craftsmanship with modern dimensional stability. Optional factory painting or staining available for enhanced durability.
Custom Architectural Accents
We create custom brackets, corbels, and gables from cedar and PVC materials. These elements match existing architectural styles or complement new constructions. Each piece receives precision cutting and finishing to ensure seamless integration with home exteriors while maintaining material-specific durability characteristics.
Deck Rail Planters
Specially designed planters for deck and balcony railings feature secure mounting systems for various rail types. Available in overhang, rail-top, and freestanding configurations, these units use the same durable materials as window boxes with optional self-watering features for low-maintenance container gardening in elevated spaces.
