Beams & Timbers

We provide precision-milled hardwood and softwood beams and timbers ideal for vaulted ceilings, dining rooms, porch covers, pergolas, and exterior accents. While we don’t construct these structures, our materials bring architectural authenticity to high-end homes and custom builds.

Sourcing the Rare, Oversized, and the Hard to Find.

When standard supply falls short, we lean on something stronger—our relationships. Mason’s Mill goes beyond the traditional lumberyard model, tapping into a nationwide network of reclaimers, farmers, and specialty loggers to source unique beams and timbers for projects that demand something exceptional.

Thermory® Benchmark Ash Decking Grooved-image

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.
