Why is my deck brown patches

Landscaping

The answer to 'why is my deck brown patches' is that the brown patches are likely caused by mold, mildew, or fungal growth on the wood. This can happen when the deck doesn't get enough sunlight, has poor drainage, or isn't properly sealed and maintained.

Some common symptoms of this issue include discolored, rotting, or peeling wood. The brown patches may start small but can spread quickly, especially in damp or shaded areas. To fix the problem, you'll need to clean the deck thoroughly, treat the affected areas, and apply a protective sealant to prevent future growth.
