Issaquah Lumber specializes in custom-milled profiles tailored for your project needs. We also offer standard profiles for decking sizes and boards that are compatible with the GRAD System. All are available in random lengths with standard widths and thicknesses.

We also offer factory-prefinished options, or you can choose from stain, paint, oiled, brushed, and charred finishes.

ACCOYA® Decking

Accoya® is a premium, sustainable wood decking available at Issaquah Lumber. Made from FSC®-certified timber and modified for exceptional durability, Accoya resists warping, rot, insects, and splintering—even in the toughest climates. Choose natural Accoya, which silvers beautifully over time, or Accoya Color Grey, with rich color all the way through.

Thermally Modified Wood Decking

Issaquah Lumber’s thermally modified wood is heat- and steam-treated—never chemically enhanced—for long-lasting performance and natural beauty. This process stabilizes the wood and protects against mold, rot, and decay while creating a deep, rich tone like exotic hardwoods.

ThermoWood®

ThermoWood® from Issaquah Lumber is a premium thermally modified wood, produced through a controlled, chemical-free process using only heat and steam. Developed in Finland, the ThermoWood process enhances the wood’s stability and durability, making it resistant to rot, decay, and insects. The result is a richly toned, sustainable wood for long-lasting performance and natural beauty.

Traditional decking

Issaquah Lumber offers natural wood decking options, including Western Red Cedar sourced from the Pacific Northwest. Prized for its warmth, workability, and timeless appeal. Naturally resistant to weather and wear, Western Red Cedar provides an authentic, sustainable choice for decks that age beautifully over time.
