Maintenance & Care


From replacing splintered boards to reapplying stain or paint, the average pressure-treated deck needs a lot of maintenance. Those supplies can add up to hundreds of dollars each year, not to mention the time spent refinishing and repairing old boards. A Fiberon composite deck? Less than $50 in annual maintenance costs and a high-end look that lasts.

Here's how to keep your deck looking like new:
  • Ensure minimum 6" ventilation under deck and required spacing between decking boards.
  • Improve drainage or grade soil to eliminate standing water under decks.
  • Direct downspouts, downspout extensions and splash guards away from decks.
  • Position dryer vents away from decks.
  • Maintain a deck that is dry and clean.
  • Clean your deck as often as needed, at least twice each year.
  • Use extreme caution with pressure washers and use at pressures less than 3,000 psi at 10" above deck surface. Wash in the direction of the grain pattern to avoid possible damage to the boards.
  • Keep debris out of gaps between the decking boards so rain showers can remove pollen and organic debris between cleanings.
  • Minimize the use of wet mulch up against the deck structure.
  • Items stored directly on top of the deck surface, such as flower pots, prohibit water evaporation and can cause some staining of the deck surface.
  • Use of wrought iron railing or other carbon steel materials in contact with or above an uncapped composite deck surface may cause dark extractive staining.
  • To remove ice and snow never use sand, use a calcium chloride-based “ice-melt” or rock salt. Do not use ice melt with an added colorant. The dyes can stain your composite decking.
