Decking Lumber FAQ

  • What Types of Decking Lumber Does Larsen Lumber Offer for Homeowners?

    Larsen Lumber offers redwood, cedar, composite, and pressure-treated decking lumber for homeowners and contractors. Redwood is prized for its natural decay resistance and rich color, while cedar stays dimensionally stable and cool underfoot in summer. Composite decking is a low-maintenance option that resists warping, fading, and moisture without requiring sanding, sealing, or staining. Our team can help match the right material to your project goals, traffic levels, and budget. Call us at (510) 357-5020 to speak with an advisor.

  • What Is the Difference Between Redwood and Composite Decking Lumber?

    Redwood is a natural wood prized for beauty and decay resistance, while composite decking is a low-maintenance engineered product that resists fading and warping. Redwood provides an authentic, warm aesthetic and accepts stains and protective finishes readily. Composite decking, however, typically requires less ongoing upkeep and may come with manufacturer warranties. In Piedmont, with its dry summers and rainy winters, both materials can perform well when properly selected and maintained. Larsen Lumber carries both options, and our experienced staff can walk homeowners through the pros and cons of each.

  • How Often Should Homeowners Seal or Stain Their Deck?

    Wood decking may benefit from sealing or staining every one to two years, depending on the lumber type and sun exposure. Clear sealers help preserve the wood's natural grain, while semi-transparent or solid stains add color and additional protection against UV rays and moisture. High-traffic areas or decks in direct sunlight may need attention more frequently. Composite decking generally does not require sealing. We recommend inspecting your deck each season for signs of wear, cracking, or loose hardware to catch issues early.

  • Why Is My Deck Lumber Warping or Cracking?

    Decking lumber may warp or crack when exposed to excessive moisture, rapid drying, or improper installation without adequate spacing for expansion. Boards stored on uneven surfaces or without proper ventilation before installation can also develop these issues. Seasonal moisture changes can stress natural wood if it lacks a protective finish or was not allowed to acclimate before building. Choosing the right lumber species for your climate and following proper handling tips can reduce the risk significantly. Larsen Lumber's team can recommend materials and preparation steps suited to your specific project.
