At St. Johns Wash and Seal, we provide professional deck and dock washing, sanding, sealing, and surface restoration for homeowners throughout St. Johns County, Florida.
Many homes in the area feature outdoor structures like decks, docks, gazebos, seating areas, and built-in features made from wood or composite materials. Florida’s sun, moisture, and water exposure can wear these surfaces down quickly. Our services are designed to clean, protect, and restore them so they stay safe, functional, and enjoyable.
Decks and docks in St. Johns County are exposed to:
Constant moisture and humidity
Direct sun and UV damage
Mold, algae, and mildew growth
Foot traffic, furniture wear, and water exposure
Without regular care, surfaces can fade, stain, splinter, or become slippery. Routine maintenance helps extend the life of both residential decks and waterfront docks.
Our washing services safely remove dirt, algae, mildew, and surface buildup from decks and docks.
