JNC Construction - San Antonio's Top-Rated Privacy Fence Installation

San Antonio's clay soil expands and contracts with moisture, weakening fence post foundations over time. Poor drainage and heavy rain can accelerate erosion, causing posts to lean or rot. JNC Construction fixes this by replacing rotted posts with concrete-set, pressure-treated wood or metal posts. We also offer fence repair and installation to ensure your fence stays level and secure for years.

Look for vines growing into fence boards, shrubs pushing against panels, or roots lifting posts. These can cause warping, rotting, or structural failure. JNC Construction provides fence cleaning, staining, and repair services. We trim back overgrowth, replace damaged sections, and recommend applying a protective sealant to prevent future moisture damage from nearby plants.

Yes, we install automatic gates designed to work with your existing fence system. For erosion-prone areas, we reinforce gate posts with deeper concrete footings and proper drainage. This prevents leaning and ensures smooth operation. We also repair and maintain manual and automatic gates, including painting or staining to protect against San Antonio's humidity.
