Top M Construction - Raleigh's Reliable Fence Builders

In Raleigh's humid summers and occasional freeze-thaw cycles, the primary cause is often rot or insect damage at the post base where it contacts the ground. Soil movement from rain can also loosen the concrete footing, making the fence unstable. Other causes include heavy winds pushing against an aging structure or poor initial installation with undersized posts. If you notice a fence leaning, it usually means the posts have lost their anchor, which can lead to larger sections sagging over time.

Look for obvious rot or mold on the deck boards, especially near the house where water collects. Another sign is if the railing feels loose or wobbly when you push against it. You may also see cracked or splintering wood, or notice that the deck surface bounces when you walk across it. If you can push a screwdriver into a deck board or post more than 1/4 inch deep, that indicates hidden rot. If the posts or joists near the ground are damaged, a full replacement might be safer than a patch job.

First, we inspect the gate's hinges and the post to see if it's leaning or loose. Often, the fix involves tightening or replacing the hinges, adjusting the gate's frame if it's warped, or installing a heavier-duty latch. If the post itself has rotted at the base, we will set a new, larger post in concrete, making sure it's plumb so the gate hangs correctly. For heavier gates, we recommend using at least three sturdy T-hinges and a self-closing latch to prevent future sagging and dragging.
