Constant moisture from rain and humidity creates ideal conditions for rot, especially if drainage is poor or the wood isn’t sealed. Regular cleaning to remove moss and applying a water-repellent sealant can help. If rot has already set in, deck repair or replacement with treated lumber or composite materials prevents further damage.

Look for widespread soft or spongy spots, large cracks, or visible fungus growth. If rot extends deep into the joists or the deck sags when you walk on it, replacement is usually safer and more cost-effective than multiple repairs.

Moss traps moisture against wood, accelerating rot and weakening fence boards. Gentle cleaning with a soft brush and a mildew cleaner removes it. Installing a fence with proper spacing and using rot-resistant materials can reduce regrowth. If damage is significant, fence replacement may be needed.
