Can you add height to an existing chain link fence?

Quick Answer

Yes, it is possible to add height to an existing chain link fence. The most common ways to do this include:

– Installing fence slats – Slats are vertical pieces of material, usually made of plastic or wood, that can be attached to the chain link wiring to add privacy and height. This is the easiest and most cost-effective way to add height.

– Adding extension arms – Metal extension arms can be installed above the existing fence frame to add 1-3 feet of additional height. This maintains the see-through chain link aesthetic.

– Installing a top rail – A top horizontal rail can be added to the top of the fence for additional height and stability. The chain link would extend above this rail.

– Adding privacy slats – For more privacy, vertical privacy slats made of wood or PVC can be installed. This offers full privacy while still allowing air flow.

– Installing new taller posts and fabric – For maximum height, new taller posts can be sunk and new fencing fabric added, either in chain link or other materials. This offers the most height but is the most labor intensive.

Adjusting the Height of a Chain Link Fence

Chain link fences provide security while maintaining visibility and air flow. They are a popular fencing choice for yards and other residential, commercial, or industrial properties. Over time, the needs of a space may change, and you may need to increase the height of an existing chain link fence. Fortunately, there are several good options to make a chain link fence taller.

Why Increase the Fence Height?

Here are some common reasons you may need a taller chain link fence:

– Increased privacy – Slats or other fill can increase privacy from neighbors or the street.

– Added security – More height deters people and animals from entering the yard or property.

– Change in pets – If you get a large dog that can jump a shorter fence, more height contains them.

– Reduced noise – A taller barrier can reduce noise from nearby roads, parks, schools etc.

– Compliance – Local codes may require a minimum fence height for pools, equipment, etc.

– Aesthetics – Increasing height can improve the appearance of the fence.

Installing Fence Slats

One easy way to add height to a chain link fence is by installing privacy slats. These are long, thin pieces of material that are installed vertically into the fencing. Common slat materials include:

– Plastic – PVC or HDPE slats are inexpensive but can be brittle. They come in various colors.

– Wood – Cedar and redwood slats look very natural but require more maintenance to keep them looking good and to prevent warping.

– Bamboo – For an eco-friendly look, bamboo slats give a stylish appearance. They need preservative treatment to last.

– Metal – Aluminum slats won’t warp or decay and are very durable, though expensive.

Slats are typically 1-2 inches wide and overlap very slightly when installed. This prevents visibility and openings but maintains airflow. Most slat systems have a locking channel to hold the slats in place securely. Proper installation is important to keep the slats from bowing or sagging over time. Expect to pay $3-8 per linear foot installed.

Adding Extension Arms

For a height increase of just 1-3 feet, extension arms can be mounted at the top of the existing fence posts. The original fence fabric is removed. The extension arm brackets are bolted onto the posts, extending them upward. New fence fabric is then tensioned between the arms.

Extension arms are a simple solution when minimal height is needed. They maintain the openness of a chain link fence since the additions are integrated. The downside is that the posts themselves are not taller, so overall structural stability is not increased. The fence may be more vulnerable to pushing or sagging. Costs are approximately $5-10 per linear foot.

Installing a Top Rail

For greater rigidity and clean aesthetics, a horizontal top rail can be added. This tubular bar is mounted across the top of the fence to the end, corner, and gate posts. Chain link fabric is then extended upward from the existing fence and attached to the top rail.

This is a relatively easy DIY project. Top rails come in standard lengths that can be overlapped and joined over posts. Endcaps finish off the ends. The key is properly tensioning the chain link fabric. A tight, taut installation prevents sagging. Top rails run $4-8 per linear foot on average.

Adding Wood or PVC Privacy Slats

For maximum privacy and wind blocking, vertical wood or PVC privacy slats can be installed instead of chain link. These fully block sightlines and provide a solid feel, acting more like a fence than a permeable barrier. Though they have no gaps, air still flows through.

Wood slats made of cedar, redwood, or pressure treated pine give a classic, natural look. PVC slats are more economical, low maintenance, and never need painting. Installation involves inserting the slats into retainers mounted horizontally across the fence. Expect to pay $10-20 per linear foot for materials and professional installation.

Installing New Posts and Fabric

To achieve significant added height, new posts can be installed above the existing fence line and new chain link or privacy fabric added. For example, a 4 foot fence could be increased to 6 feet by installing new 8 foot posts and 8 foot sections of fencing material.

This is the most labor intensive option but offers the maximum height increase. Doing a complete new installation also allows you to change fence materials if desired. You may upgrade from chain link to privacy fencing. A professional installer is recommended, at a cost of $15-25 per linear foot.

How Much Height Can You Add?

When adding height to a chain link fence, there are a few limitations to consider:

Local building codes – Most areas regulate fence height on residential properties. Be sure added height complies with codes.

Wind load – The taller the fence, the more wind force it will be subject to. Adding too much height could make the fence unstable.

Post size and depth – Existing post footing depth and diameter may limit how much you can safely extend posts.

Fabric strength – Chain link comes in various weights by the gauge of the wire. Heavier gauge may be needed for greater heights.

Top rails – Top tensioning rails have strength limits as well. Follow manufacturer specifications.

As a general guideline, here are some maximum height additions:

– Fence slats – 12-24 inches

– Extension arms – 24-36 inches

– Top rail – 12-18 inches

– New posts and fabric – Unlimited, within code

Consult with qualified fencing contractors to determine the safe height increase for your specific fence. They can assess the existing materials and recommend the best height additions.

Conclusion

Boosting the height of an existing chain link fence is a great way to increase privacy, security, and aesthetics without the cost of a full replacement. With creative use of fencing slats, top rails, extension arms, and new posts and fabric, you can find a solution to achieve your desired added height. Just be sure to consider local codes, wind factors, and fence material strength limitations when deciding how much to increase the height. With proper materials and professional installation, your heightened chain link fence will stand strong for years.
