Spring Fence Repair and Maintenance

Leaning or loose posts are the most common fence problem after winter. Check each post by pushing against it—if the post moves at ground level, the concrete footing has failed. To repair a leaning post, excavate the concrete footing, cut the post flush with the ground, and set a new post next to it using a post-hole digger and quick-setting concrete. Alternatively, use a metal post mender that drives into the ground and clamps to the existing post. For posts that are rotted at ground level, cut the rot away and use a concrete repair spur—a metal bracket that holds the post above the damp ground. Ensure all new posts are set below the frost line (typically 30–48 inches) and use concrete that is mixed to a stiff consistency.

Winter wind and snow often break loose boards or pop nails. Walk the entire fence line and replace any cracked, split, or rotting boards. Use a pry bar to remove damaged boards. Check the rails (horizontal supports) for sagging or rot. Replace any rail that flexes when pressed. Use galvanized or stainless steel deck screws instead of nails—screws hold better against wind stress and are easier to remove for future repairs. Pre-drill holes near the end of boards to prevent splitting. Maintain a 1-inch gap between the bottom of the fence and the ground to prevent soil contact that accelerates rot. For picket fences, replace missing pickets and maintain consistent spacing. Check gate hinges and replace worn hardware.

Gates take more abuse than fence sections and need special attention. Check the gate sag by lifting the latch end—if it moves up more than ½ inch, install a tension cable or replace the hinges with heavier-duty ones. Lubricate hinges and latch mechanism with WD-40 or white lithium grease. Tighten hinge screws; if screws no longer grip, replace them with longer screws or use a wood plug and new screw. Check that the latch aligns properly and the gate closes without force. Shave the latch side if the gate has expanded from moisture. Install a wheel on the latch side of large gates to prevent sag over time. Adjust the gate stop so the gate does not swing past the latch. A properly aligned gate lasts years longer than one that drags and binds.

Spring is the ideal time to clean and treat your fence. Use a pressure washer with a 40-degree nozzle at 1,200–1,800 PSI, keeping the nozzle 12 inches from the wood. Work with the wood grain. For cedar or redwood fences, apply a wood brightener (oxalic acid solution) to restore natural color. Allow 48 hours of dry weather before applying treatment. Use a clear or semi-transparent stain for most wood types—it protects against UV and moisture while allowing the wood to breathe. Apply with a sprayer or roller, back-brushing to work the stain into the wood grain. Focus especially on end grains and cut ends—they absorb the most moisture. Apply two thin coats rather than one thick coat for longer-lasting protection.
