The Ultimate Guide to Deck Cleaning and Restoration in NY

A wooden deck is a beautiful addition to any home, but in Upstate New York, it takes a serious beating. Months of sitting under heavy snow, followed by wet springs and humid summers, create the perfect environment for wood rot, algae growth, and graying from UV damage.

Why Decks Turn Gray and Slippery

When wood is exposed to the sun's UV rays, the lignin (the natural glue holding wood fibers together) breaks down, turning the wood a dull gray. Meanwhile, moisture allows green algae and black mold to take root, turning your deck into a dangerous, slippery ice rink every time it rains.

The 3-Step Professional Restoration Process

Restoring a deck isn't as simple as blasting it with water. In fact, high pressure will splinter and ruin the wood fibers. A true restoration requires a chemical process:

• Step 1: Cleaning or Stripping: Depending on the state of the deck, we apply a specialized wood cleaner to kill mold and algae, or a chemical stripper to safely remove old, failing stain and sealer without damaging the wood.
• Step 2: Low-Pressure Washing: Once the chemicals have done the work, we use very low pressure (around 500-800 PSI) to gently wash away the dead wood fibers, dirt, and old stain.
• Step 3: Wood Brightening (The Magic Step): This is the step most DIYers miss. Cleaning wood raises its pH level, making it look dark and unnatural. We apply an acidic wood brightener that neutralizes the pH, opens the wood pores, and instantly returns the wood to its original golden-honey color.

What About Composite Decks (Trex)?

Composite decking is low-maintenance, but not zero-maintenance. It still grows mold and algae. However, composite material is incredibly sensitive to high pressure—if you blast it, you will permanently scar the plastic capping. Composite decks must be soft-washed using specific detergents to protect the finish.
