Composite Deck Cleaning

What This Service Involves

Composite decks resist rot but still develop mold and algae in Washington's damp shade, especially in the textured surface grain. We clean composite with the manufacturer-friendly detergents and low pressure that lift growth without scarring the cap layer. Blasting composite at high PSI can permanently mar the finish, so we keep the approach gentle and thorough. Your low-maintenance deck returns to a clean, uniform look without any damage to the boards.
