4 Simple Ways to Increase Chain Link Fence Height

Looking to boost the privacy and security of your property? A chain link fence is a practical option, but what if you need a little more height? While chain link fences are durable and affordable, they can sometimes feel a bit too short. Luckily, there are several simple ways to elevate your fence's height without the need for extensive construction or costly materials. Whether you want to DIY or explore creative solutions, here are 4 techniques that will not only increase your existing chain link fence's height but also enhance its functionality and appeal.

1. Install Fence Post Extenders

When it comes to extending the height of your chain link fence, one of the simplest and most effective methods is installing fence post extenders.

Design

The design of these extenders is simple yet effective – they consist of metal sleeves or tubes that fit over the top of your fence posts and are then secured with screws or clamps. Fence post extenders are typically made of galvanized steel or aluminum. They come in various sizes, so you can choose one that fits the diameter of your existing t-posts or steel posts.

Pros

• No-dig, fully DIY-friendly
• Maintains original post alignment and structural stability
• Clean, seamless profile—matches standard chain-link posts

Cons

• Limited maximum extension (typically ≤ 3 ft)
• Must match the post outer diameter precisely
• Exposed metal finish may need repainting over time

Costs

• 12″ steel extender: $7.71–$8.05 each
• 3 ft adjustable extender kits: ≈ $23.88 each

Installation Process

1. Measure & Select: Confirm your post’s outer diameter and desired height gain
2. Slide On: Position the sleeve over the post until it’s flush with the top of the fence panel.
3. Level & Align: Use a level against the sleeve to ensure plumb vertical alignment. 
4. Secure: Drill pilot holes and fasten with included screws or clamps through pre-drilled holes in the sleeve.

Seal (Optional): Apply a bead of exterior-grade sealant around the sleeve’s base to shed water.

​​2. Using PVC or New Line Posts to Extend Fence Posts

Using PVC or new line posts to extend chain link fence posts is a cost-effective and practical solution for homeowners who want to add height or stability to their existing fence. 

Design

The design of this method involves attaching additional posts, made from vinyl-coated pipes or sturdy new line material, on top of the existing chain link posts. These fence post extensions are then secured with brackets or clips, ensuring a secure connection that can withstand external forces such as wind or pressure.

Pros

• Lightweight and highly weather-resistant.
• Custom-cut lengths; paintable to match décor.
• Can support attachments (trellises, lighting, planters).

Cons

• PVC may flex in high winds unless braced.
• Proper corrosion-resistant hardware is required.
• Decorative PVC can cost more than basic metal extenders. 

Costs

• 10-pack PVC rail extension kits: ≈ $159.99.
• Vinyl-coated line posts: $15–$30 per post, depending on length.

Installation Process

1. Measure Extension: Determine desired fence height extension needed and cut PVC/metal tubing to length.
2. Slide Over Post: Gently push the extension over the existing post until it seats firmly.
3. Position & Level: Check vertical alignment with a level, adjusting as needed. 
4. Clamp or Bolt: Fasten with U-bolts or metal brackets at top and bottom of the sleeve—tighten bolts evenly. 
5. Seal Joints: Fill any gaps with exterior silicone to block moisture intrusion. 

3. Add Fabric to the Top of Your Fence

If you're seeking an innovative and cost-effective way to enhance the chain link fence height, privacy, and overall appeal, consider adding fabric to the top of the privacy fence. 

Design

The design possibilities are endless when it comes to choosing the right fabric for your fence extension. Whether you prefer solid colors for a clean and modern look or vibrant patterns to add a touch of personality, there is an option that will suit your style. Additionally, the fabric can be easily customized with graphics or logos, allowing you to showcase your individuality.

Pros

• Instant privacy and sun-shade. 
• Wide range of colors, patterns, and custom prints.
• Removable and replaceable seasonally.

Cons

• Can rip or sag in high winds if over-tensioned.
• Requires periodic cleaning to prevent mildew buildup. 
• Grommets and tie wraps wear over time and may need replacement.

Costs

• 6 ft×50 ft standard privacy screen: ≈ $323.00.
• 4 ft×10 ft smaller rolls: ≈ $51.50 each.

Installation Process:

1. Prep & Measure: Lay out the screen along your fence and choose a row of diamond mesh near the top as your visual guide.
2. Install Grommets: Use a grommet tool to reinforce holes along all edges of the fabric.
3. Attach Corners: Secure the top-left corner to the tension bar with two zip ties in an “L” pattern.
4. Secure Sides & Top: Continue attaching the top edge first, then the side, keeping the fabric square and hand-tight—angle tie wraps slightly to the right.
5. Finish Bottom Edge: With a partner, smooth wrinkles and attach the bottom edge using heavier-duty zip ties or hog rings.

4. Add Welded Wire to the Top of Your Fence

Adding welded wire or barbed wire to the top of a chain link fence is another simple yet useful way to extend its height. This additional layer not only increases privacy but also provides added security for your property. 

Design

Galvanized welded-wire mesh or barbed-wire coils affix to the top rail of your chain-link fence via metal clips, zip ties, or by sandwiching between added upper rails. When considering this modification, it is important to choose a welded wire fence mesh that matches the existing chain link fence in terms of color and gauge thickness. This ensures a seamless integration that enhances the overall aesthetic appeal, whether you're aiming for a modern, industrial look or a more rustic charm.

Pros

• High deterrent value; adds security. 
• Mesh gauge/color can match the existing fence for a cohesive look.
• Can support vines for a living privacy barrier. 

Cons

• Local codes may prohibit barbed wire.
• Sharp edges pose a safety hazard during install.
• Ungalvanized mesh can rust over time.

Costs

• Welded-wire mesh: $3.50–$10.00 per linear foot.
• Barbed-wire coil: $25–$35 per 1,000 ft roll.

Installation Process

1. Select & Measure: Cut welded-wire or barbed wire to the total length of your fence sections.
2. Position: Lay the mesh atop the top rail, aligning ends precisely.
3. Fasten: Use galvanized metal clips or heavy-duty zip ties every 12–18″ to secure the mesh to the rail.
4. Add Upper Rail (Optional): For extra stability, install a second rail above the top rail and sandwich the mesh between them, tightening carriage bolts at each post.
5. Trim & Secure Ends: Twist spare wire ends back into the mesh to eliminate sharp points 

To enhance both functionality and aesthetics, consider incorporating some creative ideas into your design. For example, you could opt for decorative posts or caps along with ornamental latches for added visual appeal. Another idea is to add climbing plants or vines along the length of your extended chain link fence height to create a natural green screen effect that adds beauty and further improves privacy. Based on your local regulation and need you can use barbed wire to enhance the privacy of your fence.
