Fence & Gate Repair

The ground line is the worst place on a fence post. Below the dirt there is little oxygen, and above the dirt the wood dries in the sun. Right at the line you get both water and air at once, and that is exactly what wood-eating fungus needs. Add our rain, our humidity, and eight months of warm weather, and a post can go soft in a few years.

A few things speed it up. Lumber is the big one. Pressure-treated pine is sold in two ratings: above ground and ground contact. Ground contact has more preservative in it and is the only kind that belongs in a hole. Look at the stamp or the plastic end tag when you buy it. If the post that was used was only rated above ground, it will not last down here.

Sprinklers are next. A head that sprays the same post four mornings a week will rot it years early. Turn the head, or swap it for one that throws a lower, narrower pattern.

The concrete footing is the third culprit. If the top of the concrete is flat or dished, it holds a little bowl of water against the wood after every afternoon storm. The top of a footing should be crowned, meaning sloped away from the post like a tiny hill, so water runs off instead of sitting.

Last, keep mulch and soil pulled back a few inches from the wood, and keep vines off. A fence covered in jasmine or creeper stays damp all the time and rots from behind the leaves where you cannot see it.

Start by figuring out what is actually failing. Walk the fence and push firmly on every post at about chest height. A post that flexes and springs back is fine. A post that moves and stays moved has either rotted at the ground or lost its footing.

Then test the suspects. Poke the wood right at the dirt with a screwdriver or an old kitchen knife. If it sinks in a quarter inch with light pressure, that post is done. Sound wood will barely let the tip in. Check all four sides, because a post often rots first on the side facing the sprinkler or the soil.

Now count. If two or three posts out of twenty are bad and the boards and rails are still tight, repair is clearly the better buy. You have two choices on each bad post. You can dig the old one out and set a new one. Or, if the post is still solid a foot above grade and only the buried part failed, you can drive a steel post mender down alongside the old footing and screw it into the good wood. Simpson Strong-Tie makes one called the E-Z Mender. They run roughly ten to twenty-five dollars each, and they save taking the fence section apart.

If most of the posts are soft, or the boards are cupped, split, and gray all the way down the run, repairs just move the failure to the next weak spot.

You can do one post at a time and leave the rest of the fence standing. Back the screws or nails out where the rails meet that post only, and prop the sections on either side with a couple of 2x4s so nothing racks out of square.

Getting the old footing out is the hard part. It is often a 10 to 12 inch ball of concrete two feet down. Dig around it with a post hole digger, then break it up with a heavy digging bar, or rock it loose and haul it out whole. Some people set the new post beside the old footing instead. That works if there is room and the fence line stays straight.

For the new post, buy a 4x4 stamped ground contact, not above ground. The rule of thumb is to bury a third to a half of the height the fence stands above the ground. For a 6-foot fence that means 24 to 36 inches down. An 8-foot post buried 24 inches leaves exactly 6 feet standing, which is what most fences here use. If you want to go deeper than that, buy a 10-foot post. Make the hole about three times the width of the post, so 10 to 12 inches across for a 4x4.

Put about 4 inches of gravel in the bottom so the end grain can drain instead of sitting in a puddle. Set the post, check it plumb on two faces with a level, and brace it with two scrap boards screwed on at an angle.

With fast-setting mix you do not have to mix anything. Pour the dry concrete into the hole until it is 3 to 4 inches from the top, then pour water on it and let it soak in, about a gallon per 50-pound bag. A 10-inch hole with gravel in the bottom usually takes two to three 50-pound bags, so buy an extra. Quikrete Fast-Setting sets hard in 20 to 40 minutes.

Before it hardens, trowel the top into a small cone that sheds water away from the wood, and keep it about an inch above the surrounding dirt. Leave the bracing on at least four hours before you reattach rails, and a full day is better if a gate hangs on that post. Use exterior-rated screws, 3 inch minimum.

There are only three real causes, and you can tell them apart in about five minutes.

First, check the hinge post. Push on it. If it leans toward the gate, the gate is not sagging at all. The post is tipping under the weight, and no amount of work on the gate will fix it. That post has to be reset.

Second, check the hinges. Wood screws work their way out of a post over time, especially short ones. Take them out and go bigger: 3/8 inch lag screws about 3 inches long, or better, carriage bolts all the way through the post with a washer and nut on the back. Bolts will not pull out. If the old holes are chewed up, drill them out, glue in a hardwood dowel, let it dry, and redrill.

Third, check whether the gate frame itself has gone from a rectangle to a lopsided parallelogram. Measure corner to corner, both diagonals. If they differ by more than about a quarter inch, the frame has racked.

To pull it back square, use an anti-sag gate kit, about $15 to $25 at any home store. It is a steel cable with a turnbuckle in the middle. Run the cable from the top corner on the hinge side down to the bottom corner on the latch side. That is the diagonal that grows longer as a gate sags, so shortening it lifts the latch side back up. Getting this backward makes the sag worse, so check it twice before you tighten. Then turn the turnbuckle a few turns at a time and watch the gap at the latch close up. Stop when the gate swings clean. Overtightening will bow the frame the other way.

If the gate is heavy, a small wheel on the bottom latch corner takes the load off for a few dollars more.

Gate hardware is one place where twenty extra dollars saves you a repair in two years. The thin stamped hinges sold in a blister pack are made for a garden gate, not a 6-foot privacy gate that weighs 60 pounds.

For hinges, look for heavy strap hinges or T-hinges 8 to 12 inches long, in hot-dipped galvanized or stainless steel. Near the beaches, stainless is worth the money. Salt air eats plain galvanized hardware and streaks rust down your fence within a season or two. Use three hinges on any gate about 5 feet or taller, or anything over roughly 50 pounds, spaced top, middle, and bottom. Fasten through the post with carriage bolts wherever you can reach the back side, and use 3/8 inch lag screws where you cannot.

For latches, a gravity latch is the simplest thing that keeps working. The arm drops into a slot on its own when the gate swings shut. A thumb latch with a lift arm on both sides is nicer if you carry things through. Skip a plain hook and eye on any gate that catches wind.

If your gate is part of a pool barrier, the rules are stricter and they are not optional. Under Florida's pool safety law, a gate through a pool barrier has to open outward, away from the pool, and be self-closing and self-latching. The latch release has to be on the pool side of the gate, unless it sits at least 54 inches up from the bottom of the gate, in which case it may be on either side. There also cannot be any opening wider than half an inch within 18 inches of that release, so a child cannot reach through and flip it. The barrier itself has to be at least 4 feet high. Spring-loaded hinges plus a magnetic latch, like the common Magna-Latch style, are how most people meet this. These rules apply to pools that finished inspection on or after October 1, 2000, and to permitted work on a pool now, so call your city or county building department before you change anything on a pool barrier. This one is a child safety issue first and a code issue second.

One more tip: oil the latch and the hinge pins twice a year with a light oil or dry lubricant. Humidity and salt will seize them up.

A vinyl fence is basically a kit. The posts have slots routed in them, the rails slide into those slots, and the pickets slide into holes routed in the rails. Nothing is glued at the factory, which is good news for repairs.

To replace one picket, take the cap off the nearest post if it lifts off, then loosen the top rail or unscrew it from the post. Slide the cracked picket up and out, drop the new one in, and put the rail back. On some brands the rails are pinned or screwed where they meet the post, so run your hand under the rail and look for a small screw before you start prying anything.

Timing matters with vinyl. It gets brittle on a cold morning and soft and easy to distort in full afternoon sun, and either way it will crack if you force it. Do this work in the cool part of the morning and do not pry hard.

For small damage, a white vinyl or PVC repair caulk works on hairline cracks and stays flexible. For a clean split, PVC cement plus a patch of scrap vinyl glued on the back side holds up well, though you will see the seam from the front. Test the cement on a hidden spot first, because some vinyl fence has a coating on the outside that glue does not grab.

Matching is the real problem. Vinyl yellows and chalks in Florida sun, so a brand new white picket next to ten-year-old pickets will look brighter for a year or two. Picket widths and rail routing also differ by maker, so a panel from one big-box store usually will not fit another store's posts. Measure the picket width, thickness, and spacing, take a photo, and bring both to a local fence supply yard. They can often match older profiles that the big stores no longer carry.

A leaning vinyl post is a different and harder job, because the post is hollow and usually has a wood or concrete core buried in the footing.

Photos first. Before you straighten anything or haul a single board to the curb, take wide shots and close shots with your phone. If you end up filing a claim, the adjuster wants to see the damage where it fell, and your phone stamps the date for you.

Then do a slow walk and push on every post at chest height. You are looking for four things.

One, posts that lean or wobble. Wind loads a privacy fence like a sail, and the weak point is the post at the ground. A post that moved in a storm was usually already part rotten, so check it with a screwdriver at the dirt line while you are there.

Two, footings that heaved. After days of rain the soil goes soft, and you will sometimes see a ball of concrete tilted up out of the ground with the grass torn around it.

Three, rails and boards. Nails back themselves out and rails split where they meet the post. When you put them back, use 3 inch exterior screws rather than renailing.

Four, gates. The gate is the heaviest moving part of your fence and it takes the worst of it. Check that the hinge post is still plumb, that the hinge screws are tight, and that the latch still lines up.

Also look at what is not the fence. If a section hit the house, tore a lanai screen, or pulled on a wire, treat those as separate problems. Anything involving a wire, a service line, or a meter is licensed electrical work in Florida. Stop, keep everyone away from it, and call a licensed electrician or your utility. Do not touch a downed line even if it looks like cable or phone wire, because you cannot tell by looking.

On the money side, fence damage usually falls under the other structures part of a homeowner policy, and that part often carries its own deductible. Call your agent and ask before you spend anything, so you know whether a claim is even worth filing.

Finally, note which side the debris landed on and talk to your neighbor early. Cleanup goes a lot smoother when nobody is guessing.

Florida is hard on a wood fence. The same fence that lasts 20 years up north gets 10 to 15 here, because we hand it heat, humidity, hard sun, and daily afternoon water for four months a year.

Break it down by part. Pressure-treated pine pickets usually look tired at 8 to 12 years: gray, cupped, and split around the nails. The horizontal rails last a little longer, because water runs off them instead of soaking in. Posts are the real clock. A post rated for ground contact, set deep in a well-drained footing with a crowned top, can go 15 to 20 years. A post that was only rated for above ground, or one sitting in a footing that holds water, can be soft in 5 to 7.

Where you live matters. Within a mile or so of the Gulf or the bay, salt in the air corrodes nails and screws and speeds up everything else. Fasteners rust, boards work loose, and then the next storm does the rest. Hot-dipped galvanized or stainless fasteners are worth the extra money near the water.

What actually extends the life, roughly in order: ground-contact posts set deep with gravel underneath and concrete crowned to shed water, fasteners that do not rust, sprinklers aimed away from the wood, keeping vines and piled mulch off the boards, and a semi-transparent stain every two to three years.

If you are replacing anyway and you want the longest life, vinyl and aluminum both outlast wood down here by a wide margin, at a higher cost up front.

These two look the same from ten feet away and are completely different problems, so get close.

Rot feels wet. Press the wood with your thumb or a screwdriver at the ground line and anywhere that stays shaded. Rotten wood is spongy, sometimes stringy, and often darker or streaked with black. You may see white or tan fungus, or small shelf-shaped mushrooms on the post. Rot stays where the moisture is, so it is nearly always right at the dirt or under a rail where water sits.

Termites leave signs on the surface. Subterranean termites, which are the common ones in Pinellas County, build mud tubes: thin brown lines of soil about the width of a pencil, running up a post or across a concrete footing. Tap along the board with a screwdriver handle. Termite-damaged wood sounds hollow, and the surface can crumble into a papery honeycomb with mud packed inside. Drywood termites leave hard pellets about the size of coarse ground pepper, often in a small pile at the base of the wood.

If you find a swarm of winged insects in spring or early summer, catch a few in a sandwich bag so someone can identify them. Termites have a straight, thick waist, two pairs of wings the same length, and straight antennae. Flying ants have a pinched waist, front wings longer than the back ones, and bent antennae.

Here is the part that matters most. A wood fence touching the ground is a bridge to your house. Termite treatment is licensed pest control work in Florida, so call a licensed pest control company and have them inspect the house, not just the fence. Get that done before you spend money replacing boards, or the new wood goes the same way as the old.

The label on the can usually promises three to five years. That number was not written for Florida. Between our sun and our rain, most fences down here look dry and gray on the sun-facing side sometime in the second year.

A simple test tells you when: flick water on the boards. If it beads up, the finish is still doing its job. If it soaks in and darkens the wood, it is time.

What to use. A semi-transparent stain is the sweet spot for a fence. It soaks in instead of forming a film, so it fades rather than peeling, and the pigment in it is what actually blocks the sun. A fully clear sealer looks good for about six months and then the wood grays anyway, because there is nothing in it to stop UV. Solid-color stain lasts the longest but hides the grain and eventually peels, which means scraping later. Oil-based products generally soak in better on a fence than water-based ones. Ready Seal, Behr semi-transparent, and Thompson's WaterSeal semi-transparent are all commonly used here. Read the can before you buy, because several of these brands sell both oil-based and water-based versions under similar names, and the prep and cleanup are different.

When to do it. Aim for the dry season, roughly November through April, with no rain forecast for two or three days. The wood has to be dry, under about 15 percent moisture, or the stain will not soak in. Brand new pressure-treated lumber is usually too wet and needs to weather for a few months first.

How. Rinse or gently wash the fence, let it dry two full days, then apply with a pump sprayer or a brush. With most stains you want to go back over it right away with a brush to work it into the grain, which is called back-brushing. A few products, Ready Seal among them, specifically say not to back-brush, so follow the can. Two thin coats beat one heavy coat either way.

Most fence arguments start with two wrong assumptions: that the fence is automatically on the property line, and that the neighbor automatically owes half.

Ownership follows the property line. If the fence sits entirely on your lot, even by six inches, it is your fence. You maintain it, you pay for it, and your neighbor does not get to alter it. If it straddles the line, it is generally a shared fence and both owners have an interest in it, which is where things get delicate. Florida does not have a broad statute that forces a residential neighbor to pay half the way some other states do. Without a written agreement or an HOA rule, you cannot make them contribute.

So find out where the line actually is before you spend a dollar. Pull your survey, or look up your parcel on the Pinellas County Property Appraiser website. If you have no survey, a new one runs a few hundred dollars, which is cheap next to a dispute. Do not trust the old fence as the line. Fences drift over decades.

On the good side question, the common custom, and many HOA and city rules, is that the finished side faces out toward the street and the neighbor, with the posts and rails facing in toward you. Check your HOA documents, because some put it in writing.

Practical advice. Knock on the door before work starts and show them what you plan to do and when. If you agree to split a shared section, put it in writing, even if that is just a text message you both keep. Never remove or cut a fence you do not clearly own, and never dig on the other side of the line without asking first.

None of this is legal advice. If a neighbor is disputing a line or refusing access, talk to a real estate attorney before you spend money on the fence.

Use a simple rule: count the bad posts. Posts are the expensive part of any fence, and they are what actually holds it up.

Repair makes sense when fewer than about a third of the posts are soft at the ground, the rails are still tight, and the boards have some life left. Resetting three posts, rescrewing loose rails, and squaring up a gate might cost a few hundred dollars and buy you five more years. That is a good trade.

Replace when more than about a third of the posts are soft, when the boards are gray, cupped, and splitting along most of the run, or when you have already repaired the same fence twice in three years. Past that point, every repair just moves the failure to the next weak spot. Replacement is also the moment to rethink the material, since vinyl and aluminum cost more up front and outlast wood by a lot in our humidity and salt air.

One important difference between the two: permits. Like-for-like repairs, swapping a few boards or resetting a post, generally do not need a permit. A new fence or a full replacement usually does need one from your city, and that is work for a licensed contractor who can pull the permit. Call your city's building department, and your HOA if you have one, before you commit either way. Height limits, corner-lot visibility rules, and setbacks change block to block around here.

Here is where the money goes on a single post, so you can judge any number you get quoted.

Materials are cheap. An 8-foot ground-contact 4x4 runs about $12 to $20. Three bags of fast-setting concrete are around $20. A bag of gravel is a few dollars, and screws a few more. Call it $40 to $50 in parts.

Labor is the real cost, and it is almost all digging. Breaking out an old concrete footing two feet down, in Florida soil that may hide shell, tree roots, or the edge of an old slab, can take an hour or two per post with hand tools. Tight access makes it worse. A post in a back corner with no gate wide enough for a wheelbarrow, or a post with a hedge planted against it, takes longer than the same post out in the open.

Rough ranges you will see locally: $150 to $350 for one post reset, and less per post when several are done on the same visit, since the tools and the trip are already paid for. Driving a steel post mender alongside the old footing, when the post above grade is still solid, is faster and usually cheaper. Straightening and reattaching a leaning 8-foot section with new rails often lands between $200 and $500. Full replacement of a 6-foot wood privacy fence is typically quoted by the linear foot, commonly $20 to $45 installed, so 100 feet comes to a few thousand dollars.

Get two or three estimates and make sure each one says the same thing about how deep the post goes, whether the post is rated for ground contact, and whether hauling the old concrete away is included. A post set only 18 inches deep will lean again, and that is the corner most often cut.

Wood moves with moisture, not temperature. Between our dry spring and the middle of August, a wood gate can grow an eighth to a quarter inch across its width. That is more than most gates have to spare at the latch. It shows up worst on gates where the boards are butted tight against each other, because every board swells a little and it all adds up across the gate. The gate also gets heavier when it is wet, which can make a marginal hinge sag at the same time.

First make sure swelling is really what is happening, because swelling and sagging get confused constantly. Look at the gap between the gate and the latch post, top to bottom. If the gap is even top and bottom and simply too tight, the gate swelled. If the gap is wide at the top and pinched at the bottom, the gate is sagging, and no amount of sanding will fix it. That one needs the hinges tightened and the frame squared up.

For swelling, take off the smallest amount you can. With the gate jammed, mark the tight spot with a pencil so you know exactly where it is binding. Then prop the gate open or take it off, and remove about an eighth of an inch along the latch edge only, with a block plane or a belt sander. Never take material off the hinge edge, because that changes how the hinges sit.

Then seal the bare wood you just exposed. Fresh-cut wood soaks up water faster than finished wood and will swell worse next summer if you leave it raw. A coat of the same stain, or an exterior primer and paint, is enough.

Before you cut anything, look at the latch strike plate. Sometimes the whole fix is moving the strike a quarter inch instead of trimming the gate. That is two screws and five minutes, and it is reversible, so try it first.

Also oil the hinge pins. Humidity and salt air seize them up, and a stiff hinge feels exactly like a sticking gate.
