Professional deck cleaning in Knoxville, TN. We safely remove algae, mold, mildew, and years of grime from wood, composite, and treated lumber decks — protecting your investment and restoring the beauty of your outdoor space.
Knoxville's humid climate and heavy tree cover make decks one of the fastest surfaces to develop algae, mold, and mildew. Left untreated, biological growth penetrates wood fibers, causing rot, splinters, and structural damage that costs thousands to repair.
Our deck cleaning service removes all biological growth safely using the right pressure and chemistry for your deck material. After cleaning, your deck is ready for staining, sealing, or simply enjoying as-is — safer underfoot and looking great.
Average residential deck, up to 500 sq ft. Larger decks, railings, stairs, and pergolas priced separately.
