Deck Maintenance & Care

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 1,500 psi at 12" above deck surface. Pressure washing is not recommended when mold/mildew are present on the deck.
  • 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.
