If your wooden fence is leaning, missing pickets, or falling apart, you can fix it yourself. You can repair a wooden fence by tightening loose screws, replacing damaged pickets or rails, resetting leaning posts, or adjusting a sagging gate so it closes properly—all with basic tools and a little effort.
In this guide, I’ll break down each of these fixes step by step, so you can handle everything from a wobbly post to a crooked gate and get your fence back in shape.
How to Straighten a Wooden Fence Post
| Project difficulty: Easy to Intermediate (depends on whether you’re resetting or replacing posts) Estimated time to complete: 30 to 45 min (simple reset), 1 to 5-3 hrs (multiple posts/significant leaning) Drying time: At least 1 hour for concrete to set, 6 hours before reattaching panels for full stability, 48 hours before painting or staining Project cost: $20-$150+ (varies based on the number of posts, need for concrete, and optional reinforcements like brackets) |
A leaning post makes your whole fence look unstable and out of shape. If you don’t fix it, things could get worse. Before you start, figure out why it’s leaning. Is the wood rotting? Did the concrete base shift? Maybe the screws are loose. Fixing the root cause will help your repair last longer.
What You’ll Need
- Metal post mender or fence repair spike
- Hammer
- Galvanized screws
- Shovel
- Concrete mix
- Wooden stakes and bracing materials
- Drill
- Crushed stone (for drainage)
- Rope or bungee cord
Steps to Fix a Leaning Wooden Fence
- Check the Post
Give the post a push. If it wobbles at the base, it’s likely loose or rotting. If it’s in dirt or gravel, shifting soil might be the issue. If it’s set in concrete, look for cracks or movement.
- Brace the Post
Before fixing it, stabilize the post. Drive wooden stakes into the ground on either side. Use rope or bungee cords to hold the post upright.
- Reinforce the Base
If the post is in dirt or gravel, drive a fence repair spike next to it. Screw the post to the spike for extra support.
If the post is in concrete, use a metal post mender. Place it against the base and hammer it into the ground until it’s tight.
- Secure with Screws
Drill galvanized screws through the mender or repair spike to attach it firmly to the post.
- Reset the Post in Concrete (If Needed)
If the concrete base is cracked or shifted, you’ll need to reset the post:
- Dig out the old concrete.
- Add 4 inches of crushed stone for drainage.
- Pour fresh concrete around the post.
- Brace it while the concrete dries (at least 24 hours).
- Check and Replace Screws
Sometimes, a loose post just needs better screws. If they’re rusted or stripped, replace them with longer, galvanized screws.
- Test the Stability
Once the concrete is dry, remove the braces. Push the post to make sure it’s solid. If it doesn’t budge, your fence is back in shape.
Extra Tips
- If more than one post is leaning, check for soil erosion.
- Waterproof the post to prevent future rot.
- Tighten screws regularly to keep the fence strong.

Keep in mind: If your fence keeps leaning due to high winds, reinforcing the posts will help, but choosing a fence designed to withstand strong winds can prevent future issues. Check out our guide on Best Fences for High Winds to see which designs hold up best in tough weather.
If your post is leaning because of a slope, a repair spike or post mender might work—but sometimes adjusting for grade may require replacing or resetting the post completely for a straighter, more stable fence line.
How to Replace a Wooden Fence Post
| Project difficulty: Intermediate Estimated time to complete: 2 to 3 hours (including digging, setting the new post, and curing time) Drying time: At least 1 hour for concrete to set, 6 hours before reattaching panels for full stability, 48 hours before painting or staining Project cost: $50-$200+ (depending on the type of post, concrete, and any additional reinforcement materials like metal brackets or a post cap) |
If a post is too damaged to fix, the best solution is to replace it. A solid post keeps your fence sturdy and looking good. Here’s how to do it the right way.
What You’ll Need
- Replacement post
- Digging bar
- Concrete mix
- Shovel
- Rubber mallet
- Drill
- Screws
- 2×4 bracing
- Hammer
Steps to Replace a Wooden Fence Post
- Detach the Rails
Start by removing any horizontal rails connected to the post. Unscrew them or use a pry bar to loosen nails. Set them aside carefully to avoid damage.
- Remove the Old Post
If the post is just in dirt, you can wiggle it loose and pull it out. If it’s set in concrete, break up the base with a digging bar and hammer before pulling the post out. This makes removal easier.
- Dig a New Hole
Your new hole should be about a third of the post’s total height and at least three times wider than the post. This ensures stability. Use a post hole digger or shovel to get the right depth.
- Set the New Post
Place the new post in the hole. Use a level to make sure it’s standing straight. Brace it with 2×4 boards on either side to keep it in position.
- Pour the Concrete
Mix and pour concrete around the base. Fill the hole until the concrete is a few inches below ground level. Slope the top slightly so water drains away from the post. Let it sit for at least 24 hours before moving on.
- Reattach the Rails
Once the concrete is fully cured, remove the braces. Line up the rails and screw them back into place. Double-check that everything is secure.
Extra Tips
- If you’re replacing multiple posts, work on one at a time to keep the fence from collapsing.
- To make it more durable, seal the bottom of the post with wood preservative before setting it in concrete.
- Regularly check fence posts for signs of rot or shifting to catch problems early.
- McCullough Fencing’s Tim McCullough advises, “If your property line isn’t clearly marked, always get a survey before replacing or installing new posts. It ensures you’re not encroaching on a neighbor’s property and avoids future disputes.”
How to Replace a Wooden Fence Panel
| Project difficulty: Easy Estimated time to complete: 30 to 60 min (per panel) Drying time: 48 hours before painting or staining Project cost: $20-$100 (varies based on panel material, size, and whether new hardware like brackets is needed) |
If one of your fence panels is cracked, warped, or missing boards, replacing it is often the best fix. Here’s how to do it step by step.
What You’ll Need
- Drill
- Hammer
- Crowbar
- 2×4 hangers/brackets
- 3-inch screws
- Scrap wood (as needed)
- New fence panel
- Circular saw
Steps to Replace a Wooden Fence Panel
- Remove the Old Panel
Use a crowbar or drill to detach the damaged panel. If needed, place scrap wood behind it to prevent damage to the posts.
- Install New Brackets
Attach 2×4 hangers on both posts using screws. These will hold the new panel securely in place.
- Fit the New Panel
Before installing, check if the new panel fits. If it’s too large, trim it to size with a circular saw for a perfect fit.
- Secure the Panel
Slide the panel into place and screw it onto the brackets. Make sure it’s level and aligned with the rest of the fence.
Extra Tips
- If your fence has multiple damaged panels, replace them all at once for a uniform look.
- Use galvanized screws to prevent rust and make it sturdier.
- Check nearby panels and posts for damage while you’re at it, as it is better to fix issues early. “We walk the property perimeter with the customer to go over the exact fence line and gate locations,” says McCullough. “It helps avoid mistakes when reattaching or replacing panels.”
How to Replace a Wooden Fence Picket
| Project difficulty: Easy Estimated time to complete: 15 to 30 min (per picket) Drying time: 48 hours before painting or staining Project cost: $5-$25 (per picket, depending on wood type and size) |
Sometimes, a single picket breaks, warps, or falls off, but replacing it is an easy fix. Here’s how you can swap it out and get your fence looking good again.
What You’ll Need
- Replacement pickets
- Drill
- Screws or nails
- Hammer
- Crowbar
- Measuring tape
- Saw (if trimming is needed)
Steps to Replace a Wooden Fence Picket
- Remove the Damaged Picket
Use a drill to unscrew the damaged picket or a crowbar to pry it off. If the nails are hard to remove, tap them out with a hammer. If the picket is rotten enough, you may be able to pull it off by hand. Work carefully so you don’t damage the pickets next to it.
- Measure and Trim the New Picket
Measure the height and width of your old picket. Look for a replacement picket that matches the size and shape. If the new picket is too long, use a saw to trim it to the correct size.
- Attach the New Picket
Position the new picket in line with the others. Use a drill and screws or nails and a hammer to secure it to the fence rails. Make sure it’s straight and evenly spaced.
Extra Tips
- Place a piece of scrap wood behind the picket while prying to protect the fence rails.
- Check for loose pickets nearby while you’re at it and tighten them up.
- Apply wood sealer or paint to match the new picket with the rest of your fence.
- If you’re working around obstacles like tree limbs, wood pickets can be trimmed to accommodate. “We can trim the pickets around tree limbs so the fence line is not interrupted,” McCullough says. “That flexibility is one of the biggest advantages of a wood fence.”
How to Repair a Wooden Fence Rail
| Project difficulty: Easy to Intermediate (depending on the extent of damage) Estimated time to complete: 30 to 60 min Drying time: 48 hours before painting or staining Project cost: $10–$50 (for rails, screws, or nails) |
If a rail is loose, cracked, or broken, it can make your entire fence unstable. Fixing or replacing a damaged rail will help keep your fence solid and looking good.
What You’ll Need
- Replacement rail (if needed)
- Screws or nails
- Drill or hammer
- Wood glue (optional)
- Brackets (if reinforcement is needed)
Steps to Repair a Wooden Fence Rail
- Inspect the Rail
Take a close look at the rail. Check if it’s loose, cracked, or completely broken. Sometimes, a rail may just need a few screws — other times, it may need to be replaced.
- Reattach a Loose Rail
If the rail is simply loose but not broken, reinforce it. Add screws or nails where the rail meets the fence posts to tighten it up.
- Replace a Severely Damaged Rail
If the rail is badly cracked or broken, remove it. Measure and cut a replacement rail to match the old one. Attach it to the fence posts using screws or nails.
- Use Brackets for Extra Support
If the rail isn’t holding well, install metal brackets where the rail meets the posts. This is especially helpful if the wood is old or weakened.
Extra Tips
- For small cracks, you can also apply wood glue to help hold the rail together. Clamp it until the glue dries.
- Give the entire fence a quick inspection after repairs to catch any other weak spots.
How to Fix a Sagging Wooden Fence Gate
| Project difficulty: Intermediate Estimated time to complete: 1 to 2 hours (depending on the severity of the sag) Drying time: 48 hours before painting or staining Project cost: $20-$75 (includes hardware like hinges, anti-sag cables, and any concrete if needed) |
A sagging gate can be frustrating. It can drag on the ground, stick, or not close properly. Luckily, you can fix it once you know what’s causing the problem.
What You’ll Need
- Fence repair spike
- Concrete mix
- Screws
- Drill
- Anti-sag cable kit (for lopsided gates)
- Wood filler (optional)
Steps to Fix a Sagging Wooden Fence Gate
- Fix a Loose Gate Post
If the post holding the gate is leaning or wobbly:
- Drive a fence repair spike into the ground next to the post. Attach the post to the spike using screws.
- If the post is set in concrete but still loose, add fresh concrete around the base. Let it cure fully before using the gate.
- Tighten or Replace Loose Hinges
If the gate is sagging because the hinges are loose:
- Tighten the screws holding the hinges.
- If the screw holes are stripped, use longer screws or fill the holes with wood filler before reinstalling the screws.
- Install an Anti-Sag Cable Kit
If the gate is crooked or dragging:
- Attach an anti-sag cable kit from the top corner of the hinge side to the bottom corner on the latch side.
- Tighten the cable until the gate is level and square.
Extra Tips
- Check the latch after repairs to make sure it lines up properly.
- Apply wood sealer or paint to protect the repaired areas.
- Regularly inspect gate hardware and posts to prevent future sagging.
