Landscape Depot - Huntsville's Best Fence Installation

That warping is almost always caused by direct, prolonged sun exposure and moisture imbalance. In our Huntsville climate, the intense sun heats the outer face of the wood, rapidly drying it out. This causes the wood fibers to shrink and curl inward, while the inner face of the board stays cooler and more moist. The stress between these two sides pulls the boards loose from the frame rails. A good preventative solution is to ensure your fence is properly stained with a high-quality UV-blocking finish on the sunny side. Regular landscape maintenance, like keeping tall grass and vines from holding extra moisture against the base of the fence, can also reduce the temperature difference that causes warping.

The most common early sign is a noticeable 'cupping' or 'curling' shape to individual pickets or boards. You might also see small cracks beginning at the ends of the boards, or notice that the gaps between pickets are becoming uneven. Another sign is that the nail or screw heads are pulling through the wood surface, or new gaps are appearing between the fence pickets and the rails. If you see any of these signs, especially on south or west-facing sections of your fence, it's best to have a pro take a look before the whole section buckles.

Strategic landscaping is one of the best ways to protect your fence from heat damage. First, our tree care services can prune limbs to provide dappled shade to the sunniest sides of your fence during the hottest parts of the day. This direct shade reduces the surface temperature of the wood. Second, regular landscape maintenance prevents plant overgrowth that traps moisture against the fence base, which creates a moisture gradient that fuels warping. Finally, keeping ground cover properly trimmed ensures airflow around the bottom of the fence, which helps it dry evenly after rain.
