Best Protective Treatments for Wood Fences
A wood fence is an investment in privacy, security, and curb appeal. But without proper protection, Texas heat, rain, and pests can quickly damage even the highest-quality wood.
Whether you have a cedar privacy fence in San Antonio or a ranch-style pine fence in Comal County, understanding which treatments work best can help extend your fence’s lifespan and maintain its natural beauty.
🌞 Why You Need to Treat Your Wood Fence
Texas weather can be harsh on wood fences. UV rays cause fading and dryness, while heavy rains and humidity promote mold, mildew, and rot. Insect infestations—like termites—can also threaten your investment.
Treatments help to:
Prevent moisture absorption, reducing rot and warping
Block UV rays, minimizing color fading and cracking
Protect against insects, including termites and carpenter ants
Enhance natural color, improving curb appeal
