Hardwoods

From millwork and furniture to cabinetry, flooring, and architectural detailing, the right hardwood makes the difference. Mason’s Mill & Lumber supplies domestic and imported hardwood lumber — precision-sawn, grade-selected, and ready for your next project.

Interior & Exterior Hardwoods

Hardwood is prized for its strength, durability, and natural beauty. Unlike softwoods, hardwoods originate from broadleaf trees and generally offer greater density, wear resistance, and distinctive grain patterns that enhance design value.

What hardwood brings to your project:

    • Superior durability and longevity — ideal for interior and exterior applications with frequent use.

    • Rich visual character — distinct grains and hues elevate millwork, cabinetry, and furniture.

    • Design flexibility — accepts staining, finishing, and machining with precision.

    • Long-term value — hardwood elements often boost resale and finish quality.

Thermally Modified Ash Rough Lumber-image

Details

Thermally modified ash rough lumber offers the classic, timeless sophistication of real wood combined with the exceptional durability that results from the thermal modification process. When it comes to rot resistance and stability, this ash rough lumber will take on any other real wood product, including tropical woods and other modified hardwoods. Meticulous milling means clean lines, tight seams and easy installation.

The thermal wood process modifies each board completely, all the way through to the core, leading to unequalled durability and stability without sacrificing the natural qualities of real wood.

Ash is regularly used for furniture, flooring, doors, architectural millwork and moulding, kitchen cabinets, paneling, tool handles, baseball bats, hockey sticks, skis, oars and turnings. The sapwood is light-colored to nearly white and the heartwood varies from greyish or light brown, to pale yellow streaked with brown. The wood is generally straight-grained with a coarse uniform texture.

The degree and availability of light-colored sapwood, and other properties, will vary according to the growing regions.

Frequently Asked Questions

Hardwood lumber comes from broadleaf trees and is valued for its density, strength, and grain complexity — making it ideal for furniture, cabinetry, flooring, and detailed millwork.

Hardwoods generally have a more complex cellular structure with greater density and stronger wear resistance than softwoods, which are often lighter and more uniform.

Cherry, Walnut, Maple, and Oak are popular choices due to their workability, finish acceptance, and grain character.
