How to Fix a Fence
The first step in repairing a damaged fence is to assess it to establish what’s wrong and determine the scope of the damage. The damage may be an isolated incident or something more major that requires replacement. Consider not only the fence materials, but the long-term solutions as well. With regular maintenance, you can identify small issues before they become bigger ones.
Is the Post Damaged?
Reinforcing posts by adding braces to support the post base is the simplest type of fence post repair. Simply drive the brace into the ground and attach the brace to the undamaged section of the post.
Is the Fence Gate Sagging?
If the fence is sagging, reinforce it with a no-sag kit to bring it back to square.
Is the Fence Dirty or Does it have Mold or Mildew?
A vinyl fence is more likely to have dirt that’s easy to clean with a spray of the garden hose. A wood fence is more susceptible to mold or mildew, especially if it’s in shady or damp areas. If your fence has dirt, mold or mildew, use a pressure washer to clean it. Let it dry completely and then apply stain.
Are Animals Digging Underneath Your Fence?
If you have a dog that digs under your fence, you may need to address a behavioral issue at some point. In the meantime, create a physical barrier to prevent or discourage digging.
- Lay a row of patio pavers or landscape timbers along the bottom inside of the fence perimeter.
- Bury chicken wire or hardware cloth in an L-shape at the base of the fence. This method can also keep unwanted animals out of your garden. Make sure the mesh size of the fence is large enough or small enough that your pet's paws won't get caught in it.
How to Repair a Broken Fence Post
Fence post issues (rotted, loose or leaning) all require the same basic fixes. Loose or leaning posts need to be reinforced. Carefully dig around the base to the concrete footing. Straighten the post, check for level, brace it and repour concrete to set. Let the concrete cure according to the manufacturer’s instructions.
While a rotted wood post may seem like it’s unrepairable, you may be able to salvage it if the rot isn’t extensive. Remove all of the crumbling, spongy or soft rotted wood with a chisel or a rasp to reach solid wood. Apply a wood filler to stabilize the wood fibers and allow it to dry completely, according to the filler’s label directions. Once the filler is dry, sand, smooth, stain and paint. You can, however, opt to replace the entire post and set it in concrete as the other posts were originally done.
How Much Does It Cost to Repair a Fence?
The cost to repair a broken fence varies and is dependent upon several factors, including the type of fence, the extent of the damage, material costs, location and labor. The average cost to repair a fence is $609, with homeowners paying roughly between $300 and $950.
When estimating fence repair costs, consider if you’re able to make the repairs yourself. If you’re not the DIY (do-it-yourself) type, make sure to get multiple quotes and remember to factor in labor costs. When it concerns repair questions like how to brace up a wooden fence or how to fix a leaning wooden fence, a professional may be better prepared to give you a knowledgeable answer. Whether you’re looking at replacing a wood fence, wood fence repair costs, a wrought iron fence or a vinyl fence, make sure you’re clear about the extent of the fence damage and don’t be pressured into settling for repairs that you don’t want or need.
Fence Maintenance by Material
Maintaining your fence is an important step in ensuring its longevity, no matter what materials it’s made from. It's vital not only for your home’s curb appeal but for its functionality as well. A little pre-emptive care now goes a long way in helping keep your maintenance costs down in the future.
Electric or Wire Fences
Make sure your electric fence is grounded and that the insulators aren't broken. Wire and woven wire fences need sufficient — but not excessive — tension to be effective. As with any fence, regular inspection is advised.
Metal Fences
Metal fences are durable and don't require a lot of maintenance. Fix the occasional scratch by cleaning away rust with steel wool or, for larger areas, an angle grinder with a wire brush attachment. Touch up the paint when finished.
Vinyl Fences
Compared to other fence material options, vinyl is low maintenance, but any fence can get dirty. Regular cleaning will keep it attractive for years. Replace damaged or cracked components as you find them. Make sure the posts are still plumb and solidly in the ground.
Wood and Bamboo Fences
Wood is especially prone to expanding and contracting over time. Weather (either dry or wet) can cause sagging, splitting or warping. It’s a good idea to apply stain or sealer soon after installation to avoid having to repair a wood fence earlier than expected. Follow the specific instructions for your type of wood to know how soon you can apply stain.
If you need to replace boards or panels, remember that the new wood will be a different shade than the old wood. Painting or staining the entire fence is one remedy, or you can let it weather naturally.
General Fence Maintenance
While regular maintenance won’t totally eliminate the need for repairs in the future, it’ll help to preserve the fence and maintain its longevity.
- Inspect your fence regularly.
- Paint or stain your fence as needed to protect it from the elements.
- Clean regularly with products and methods recommended by manufacturers.
- Be careful when using mowers and string trimmers around fences and posts.
- Avoid letting mulch or soil pile up against the bottom of fence posts and panels.
- Keep hinges, latches and any moving parts well lubricated with grease or oil.
- Mend a fence quickly if only a small portion is damaged. This will protect the structural integrity of the rest of the fence.
Planning For Your Fence
- Consider the amount of post-installation maintenance required when you’re choosing a fence.
- Know your property lines and ensure they’re properly marked.
- Evaluate slopes on your property and choose the proper fence for your landscape.
- Before digging, call 811 to get in touch with your local utility companies. They’ll come out and mark any underground service lines on your property.
- Review and follow all local fencing laws and ordinances.
- If you live in a development with a Homeowners Association (HOA), ensure that you’re in compliance with their guidelines before proceeding with installation.
- Measure correctly, dig the proper post hole and ensure posts are plumb and level.
