Fence repair in Lexington: posts, gates, storm damage and when to rebuild

Start with a walk along the whole fence

Before calling anyone, walk the full length of the fence, both sides if you can reach them. Push gently on each post at shoulder height. A sound post barely moves; a failing one rocks, creaks or shifts at the base. Look down at ground level, where most trouble starts, and look along the top rail from one end to sight any dip or bulge in the line.

Take photos of each problem spot and note roughly how many posts, rails and boards are involved. That list makes it much easier for a contractor to give a useful answer over the phone and to bring the right materials on the first visit. It also shows whether you are dealing with one isolated failure or a fence that is wearing out everywhere at the same time.

• Posts that rock, lean or have lifted out of the ground
• Soft, dark or crumbling wood at the soil line
• Rails pulled loose from posts, or split where they are nailed
• Gates that drag, bind or no longer latch without lifting
• Missing, cracked or cupped boards and pickets

Frost-heaved and leaning posts in Bluegrass clay

Central Kentucky clay holds a lot of water, and winters here freeze and thaw many times. When wet clay freezes it expands and grips the side of the post and the concrete footing, lifting both a fraction each cycle. A post that was set shallow, or with a concrete footing shaped like a mushroom at the top, is especially easy for frost to jack upward. After a few seasons, a heaved post sits higher than its neighbors, the rails tilt, and the gate on that post stops lining up.

Leaning has other causes as well: a post that has rotted at the base, soil washing away on a slope, a large tree root pushing from one side, or wind acting on a tall privacy section. Figuring out which one it is decides the repair. A heaved post in sound wood can sometimes be reset deeper. A rotted post has to come out. A post pushed by a root may need to be moved a short distance along the line.

Replacing a post without tearing down the section

A single failed post can usually be swapped without replacing the fence around it. The contractor supports the rails, detaches them from the bad post, breaks out or pulls the old footing, and sets a new post at proper depth, often with gravel in the bottom for drainage. Pulling an old concrete footing is heavy work, and in yards where limestone is close to the surface the new hole may need a rock bit or a slight shift in position.

Another common approach is a steel post repair bracket or a mender driven beside the damaged post and bolted to it. That can buy time on a fence that is otherwise in good shape, but it is a patch rather than a new post. It works best when the post above ground is still sound and only the base has failed. Ask which approach is being used and why.

Rot at grade and why wood fails at the soil line

Wood posts almost always rot at the same spot: the band just above and just below the ground, where moisture, oxygen and fungi all meet. Pressure-treated posts rated for ground contact last far longer than untreated ones, but water pooling against the post, a concrete collar that traps moisture, or mulch and soil piled against the wood all speed the decay. Push a screwdriver into the post at the soil line. If it sinks in easily, the post is failing even if it still stands straight.

Bottom rails and the lower ends of pickets rot the same way when they sit in soil, grass or leaves. A rot board, a horizontal board along the bottom that can be replaced by itself, protects pickets and is easy to add during a repair. Keeping mulch and soil pulled back a few inches from the fence and trimming grass along the line helps every wood fence last longer.

Gate sag and the fixes that actually hold

Gate problems send more people looking for fence help than anything else. A sagging gate is usually one of three things: the hinge post is leaning, the hinges or their screws have loosened, or the gate frame itself has racked out of square. The fix depends on which. Tightening hardware with longer screws or through-bolts solves a loose hinge. A leaning hinge post needs to be reset or replaced, and no amount of hardware will fix it until it is.

A gate that has racked out of square needs its frame brought back into shape. On wood gates, a diagonal brace running from the bottom of the hinge side to the top of the latch side carries the weight back to the hinges. An anti-sag cable and turnbuckle kit adds adjustable support. Wide gates may need a steel frame or a wheel at the latch end. Once the gate hangs true, the latch often needs to be moved to line up again.

Wind, falling limbs and spring storm damage

Spring and early summer in the Bluegrass bring thunderstorms with strong gusts, and older shade trees across Lexington neighborhoods drop heavy limbs onto fences every year. Solid privacy sections catch wind like a sail. When the posts are sound, a storm may only break rails and knock boards loose. When posts were already weak at the base, a whole section can lie down at once.

After a storm, clear the limb carefully, or have a tree service do it if it is large or tangled with power lines. Never go near a downed line. Photograph the damage before anything is moved. A contractor can usually re-stand a section with sound posts by bracing it, replacing the broken rails and reattaching the boards. If several posts in a row snapped or pulled out of the ground, rebuilding that run with new posts set deeper is often the more lasting repair.

Replacing boards and matching weathered wood

Replacing cracked, split or missing boards is straightforward. The hard part is looks: new pine is pale green or yellow, while a fence that has stood a few years has faded to gray or taken on stain color. A fresh board will stand out for a while no matter what. Treated pine needs to dry for a period before it takes stain well, and new cedar weathers toward gray on its own over several months.

The contractor should match the board thickness, width and profile, and use the same style of cap or trim. If the fence was stained, a matching stain can be applied once the new wood is dry enough to accept it, and some owners choose to restain the whole run so everything evens out. Use exterior-rated screws or ring-shank nails when reattaching boards, because smooth nails tend to back out as the wood swells and shrinks.

Vinyl and chain link repairs

Vinyl fences come apart differently. Panels pop out of the post routing after an impact or strong wind, pickets crack in cold weather when struck, and posts lean when the concrete footing inside has shifted. Many vinyl parts can be replaced individually if the same product line is still available, so find the brand or any leftover pieces if you have them. Color can be hard to match on older vinyl that has faded or yellowed.

Chain link is one of the most repairable fences. A bent top rail can be cut out and a new section sleeved in. Stretched or torn mesh can be re-tied or spliced with a new piece woven in, and loose tension bands can be tightened. Leaning terminal posts are the main structural concern, since they hold the tension of the whole run; if a corner or end post moves, the fabric sags all the way down the line.

Repair or replace: how to make the call

There is no single rule, but a few signs point one way or the other. Repair makes sense when the damage is limited to a few posts or a gate and the rest of the fence is sound. Replacement starts to make more sense when many posts are soft at the base, the boards are brittle and splitting across the fence, or the fence has been patched so many times that each storm brings a new failure. Spending heavily to keep a worn-out fence standing usually just delays the rebuild.

Ask the contractor to spell out what a repair includes and what it does not. A fair repair proposal lists which posts are being replaced, how they are set, what hardware is used, how debris is hauled away, and what condition the untouched parts of the fence are in. If a rebuild is recommended, ask them to explain what they found, and consider asking for both options priced so you can weigh them.
