Planning a new deck installation in King County? Whether you’re in Snoqualmie, Bellevue, Issaquah, or Maple Valley, your deck will face plenty of rain, moisture, and maybe even snow. Choosing the right decking materials ensures your deck looks great and lasts for years with minimal maintenance.

Best Decking Materials for Rainy Washington Weather

• Pressure-Treated Wood Decking:
  • Most affordable option.

Is Composite Decking Worth It in King County?
