From modern rainscreen systems to traditional lap siding, our mill offers the quality, flexibility, and speed your project demands.
Mon Reale Ornamental Mouldings
Mon Reale is White River's premier line for high-relief ornamental detail. A fine-grain overlay is contoured onto solid Poplar, producing a consistent closed-grain surface that takes paint and stain evenly while still installing with standard woodworking tools.
Profiles are drawn to be used alone or stacked into larger-scale built-up assemblies - crowns over friezes over panel moulds - so a single line can carry an entire room trim package at any scale.

Frequently Asked Questions
Both protect and define a building’s exterior, but “siding” typically refers to materials used on residential homes, while “cladding” is the broader architectural term used for commercial or custom applications. At Mason’s Mill & Lumber, we supply both—custom-milled to suit your project’s design and performance requirements.
Yes. Our in-house mill can match or reproduce nearly any profile from drawings or samples. Whether you need shiplap, tongue-and-groove, channel, or modern rainscreen cladding, we can produce precise dimensions, edge details, and finishes for a perfect fit.
We recommend durable, stable materials that can handle heat, humidity, and UV exposure—such as Thermory® thermally modified wood, Accoya® acetylated wood, or Modern Mill ACRE™ composite. Each performs exceptionally well in harsh environments while maintaining its appearance for decades.
A rainscreen system creates an air gap between the siding and the building envelope, allowing trapped moisture to escape. This design helps prevent rot, mold, and warping, while improving energy efficiency. Many of our products are ideal for rainscreen installation.
Yes. We ship and deliver materials throughout Texas and across the U.S., with next-day delivery available for many stocked items. For large or custom orders, our team coordinates logistics to ensure materials arrive on time and in excellent condition.
Yes. We stock the full range of exterior accessories so your siding system performs as intended.
Available options include:
Stainless or coated screws and clips designed for wood and composite rainscreen systems
Specialized drill bits, trim hardware, and concealed fastening options
High-quality sealers, oils, and stains formulated for exterior woods
Color-matched corner boards and trim materials
Our team can help you pair the right hardware and finish system with your chosen material — ensuring consistent aesthetics and long-term performance.
A rainscreen system is a modern cladding design that includes a small ventilation cavity between the cladding boards and the wall sheathing. This gap allows moisture to drain and air to circulate, protecting the structure from trapped humidity and water damage.
Benefits include:
Longer material lifespan and reduced maintenance
Improved building envelope performance
Better indoor air quality through moisture control
Compatibility with vertical and horizontal installations
At Mason’s Mill, our materials like Accoya®, Thermory®, and Modern Mill ACRE™ are ideal for rainscreen applications, combining dimensional stability with resistance to rot and decay.
