Tips to Prolong Deck Railing Durability
Maintenance Tips That Help Prolong The Life of Deck Railings


  • Frequency: Regularly clean your railings, ideally twice a year (spring and fall) or more often in high-traffic areas.
  • Method: While tempting, high-pressure washers can damage your railings. Stick to a gentle handwashing with mild soap and a soft-bristled brush.
  • Addressing Stains: For stubborn deck stains, use a specifically formulated deck cleaner or a mixture of white vinegar and water (1:1 ratio). Test on a small inconspicuous area first.
  • Mold and Mildew: If you notice mold or mildew growth, use a solution of bleach and water (1:10 ratio) and scrub gently. Rinse thoroughly and allow to dry completely.


  • Inspections: Conduct regular inspections, at least twice a year, to identify any loose screws, damaged posts, or cracked balusters. Tighten loose screws, and replace damaged components promptly to maintain structural integrity.
  • Hardware: Use high-quality stainless steel screws and fasteners specifically designed for outdoor use. Avoid using regular screws, as they may rust and corrode over time.
  • Winter Prep: Before winter, remove any debris or leaves accumulated on the railings to prevent moisture buildup and potential damage.

Additional Tips:

  • Minimize scratching: Avoid dragging furniture or heavy objects across the railings.
  • Control vegetation: Keep plants and vines away from the railings, as their growth can trap moisture and promote mold growth.
  • Prevent water pooling: Ensure proper drainage around your deck to prevent water from pooling around the railings and causing damage.
  • Consider protective coatings: While not always necessary, applying a clear sealant or protectant designed for composite railings can enhance their resistance to fading and staining. Follow the manufacturer's instructions for application.


  • Always follow the specific cleaning and maintenance recommendations provided by your railing manufacturer.
  • Store cleaning supplies and tools away from children and pets.
  • If you have any concerns about the condition of your railings, consult a professional deck builder or contractor.

By following these expert tips, you can ensure your composite deck railings remain a beautiful, safe, and long-lasting addition to your outdoor space for years to come.
