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.
Thermory® Benchmark Ash Decking Grooved
$$$
Thermory® Benchmark Ash decking is exceptionally durable and dimensionally stable with deep, rich color. Thermory® Benchmark Ash Decking is your timeless, stunning, long-lasting, barefoot-friendly, installs-in-a-breeze, real wood dream deck. The Thermory® process modifies each board completely through heat and steam, all the way to the core, leading to unequalled durability and stability without sacrificing the natural qualities of real wood.
Grooved for PaCS for a fastener free deck surface, and Joint End Matched (JEM), which is a machined structural end match that connects boards so you don't need to finish decking on a joist.
