Your Pre-Project Checklist
A successful project begins with meticulous planning. Before purchasing any materials or picking up a single tool, ensure you complete the following checklist.
Assess Current Conditions: Carefully inspect your existing fence posts and mesh for any signs of damage, rust, or instability. A weak foundation cannot support added height.
Measure Everything Accurately: Record the total length of the fence, the current height of the posts, and, most importantly, the outer diameter of your existing posts.
Check Local Regulations: This is critical. Contact your local municipality or homeowners' association (HOA) to inquire about any legal restrictions on fence height.
Define Your Primary Goal: Are you trying to achieve total privacy, stop a dog from jumping, or simply improve curb appeal? Your goal will dictate the best method.
Set Your Budget: Determine a realistic budget for materials and potential tool rentals. This will help you narrow down your options from the start.
The 6 Fence Extension Methods in Detail
Methods for Maximum Privacy & Style
Method 1: Attaching Wooden Planks or Slats
This method involves weaving or attaching wooden slats to the existing chain link mesh, effectively turning it into a wood-style privacy fence.
Pros: Unmatched privacy and aesthetic appeal; can dramatically change the look of your yard.
Cons: High material cost; significantly increases wind load, which can strain fence posts; labor-intensive.
Step-by-Step Guide:
Ensure your fence posts are secure and in good condition.
Measure and purchase pressure-treated or cedar planks.
Attach the planks vertically or horizontally to the chain link fabric using U-bolts or heavy-duty zip ties.
Method 2: Installing Privacy Fabric or Screen
A straightforward solution where a specialized, tightly woven fabric is attached directly to the fence.
Pros: Fast and easy to install; offers immediate privacy; relatively inexpensive.
Cons: Can be damaged by high winds if not installed correctly; aesthetics are functional rather than decorative.
Step-by-Step Guide:
Choose a screen that matches your desired height extension.
Starting at one end, securely fasten the screen's grommets to the top rail and fence mesh using zip ties.
Keep the screen taut as you work your way down the fence line to prevent sagging.
Methods for Security & Keeping Pets In
Method 3: Using Metal Post Extenders
These are sleeves or inserts designed to fit snugly onto your existing posts, allowing you to attach a new, taller top rail and an extra section of chain link mesh.
Pros: Creates a seamless, professional-looking extension; very durable and secure; maintains the original fence style.
Cons: Requires purchasing and stretching a new roll of chain link mesh; moderate difficulty.
Step-by-Step Guide:
Remove the existing top rail.
Install the post extenders onto each vertical post, securing them with the provided hardware.
Install a new, taller top rail and stretch the new section of chain link fabric between the old and new rails.
Method 4: Adding Welded Wire Mesh
This involves attaching a roll of sturdy, welded wire mesh to the top of your existing fence, creating a barrier that is difficult to climb or squeeze through.
Pros: Excellent for keeping pets in or other animals out; more secure than plastic netting.
Cons: Can have an industrial look; requires careful handling to avoid sharp edges.
Rongtai Pro Tip: How to Choose the Right Wire Gauge
For a Cohesive Look: Try to match the wire gauge (thickness) of the welded wire to your existing chain link fabric. Common gauges are 9 to 11.5—remember, a lower number means a thicker, stronger wire.
For Higher Security: If security is your top priority, opt for a thicker gauge (like 9-gauge) and a smaller mesh opening. This makes the wire harder to cut and more difficult to climb.
Step-by-Step Guide:
Unroll the welded wire mesh along the top of your fence.
Use heavy-duty wire or metal zip ties every 12-24 inches to securely fasten the bottom of the new mesh to the top of your existing fence fabric.
Ensure the top edge is taut and level.
Method 5: Using Extend-an-Arm Brackets
These are angled metal arms that bolt onto your existing posts, allowing you to run barbed wire or high-tensile wire at a 45-degree angle for added deterrence.
Pros: Excellent deterrent for climbers (both human and animal); low material cost.
Cons: Creates an industrial or high-security look that may not be suitable for all residential areas; check local regulations on barbed wire.
Step-by-Step Guide:
Bolt one bracket securely to the top of each fence post.
Ensure all brackets are facing the same direction (inward or outward).
String several strands of wire through the notches on the arms.
Method 6: Slipping on Taller Replacement Posts
This "brute force" method involves detaching the existing fence fabric, driving taller posts directly over the old ones, and then reattaching the fabric higher up.
Pros: Very strong and stable result; allows for significant height increases.
Cons: Labor-intensive and difficult; requires enough slack in the existing fence fabric to be raised.
Step-by-Step Guide:
Untie the fence mesh from the top rail and posts.
Use a sledgehammer to drive a taller, larger-diameter post directly over each existing post.
Re-stretch and re-attach the chain link fabric at the new, higher position.
Frequently Asked Questions (FAQ)
Q1: Can I really add height to my fence without replacing it?
A: Absolutely. All 6 methods let you build upon your existing posts and foundation. This means you get to skip the hardest part of a new installation, saving you significant time and money.
Q2: How do I ensure the added height is stable and won't fall in the wind?
A: The key is a strong foundation. First, ensure your existing posts are secure and not rusted through. Second, for methods that add significant surface area (like wood slats or privacy screens), consider reinforcing your main posts with concrete footings.
Q3: Will adding height affect my fence's appearance?
A: Yes, but you can control the outcome. Methods like metal post extenders offer a seamless look, while adding wood slats can create a brand-new aesthetic. Choose the method that best aligns with your desired visual style.
Q4: Are there legal restrictions on how high my fence can be?
A: Almost certainly. Most cities and HOAs have rules governing fence height, especially for front yards versus backyards. Always check with your local authorities before you begin any work.
Q5: How can I deter animals from climbing the taller fence?
A: Angled brackets (Method 5) are a strong deterrent. You can also install a "roller bar" (a pipe that spins freely) along the top rail, which prevents animals like raccoons or coyotes from getting a solid grip.
Conclusion: Choosing the Right Path to Privacy and Security
Increasing the height of your chain link fence is a manageable project that can deliver immediate results for your home's privacy and security. The key to success is choosing the right method for your specific goal, budget, and existing fence conditions.
