Enhance Your Outdoor Space with High-Quality Decking Solutions
At Mason’s Mill & Lumber Co., we’re proud to offer one of the most comprehensive selections of high-quality decking products in the state.
Whether you’re designing a new deck or enhancing an existing one, we provide a variety of options to suit your project. Our hardwood selections include Ipe, Garapa, and Cumaru from South America, known for their durability and natural beauty.
For those looking for advanced solutions, we distribute a wide range of modified woods that are recognized for their exceptional resilience and performance compared to traditional treated or tropical wood. These brands include Thermory, Accoya and Kebony. Industry leading composite and pvc decking options from Timbertech, Deckorators, and Modern Mill Acre are also available.
Beyond standard decking sizes, we also offer larger dimensions for stairs, benches, and handrails to help you create a cohesive look.
