Can you add height to a fence?

Adding height to an existing fence is certainly possible for most homeowners. The key considerations are choosing the right materials, preparing the existing fence properly, and using the correct techniques to extend the fence vertically. With some planning and elbow grease, you can increase the height of a fence to boost privacy, security, and aesthetic appeal.

What are the best materials for extending fence height?

The best materials for adding height to a fence depend on the existing fence type:

• For a wood fence – Additional wood boards, planks, or panels are ideal. Match the new wood to the existing as closely as possible.
• For a chain link fence – Metal fence slats or privacy mesh are good options. Look for UV-resistant materials.
• For a vinyl fence – Extruded vinyl boards in the same style and color as the original fence are best.
• For a wrought iron or metal fence – New metal pickets in the same style and finish can seamlessly add height.

It’s important to use weather-resistant, durable materials that are designed for outdoor use and can stand up to the elements. Pressure-treated lumber, composite wood, aluminum, and steel are common choices.

How should you prepare the existing fence before extending it?

Proper prep work is crucial when adding height to a fence. Here are some key steps:

1. Inspect the existing fence posts – They must be plumb and structurally sound to support increased height. Reinforce posts if needed.
2. Check for rot, cracks, or damage – Repair any issues to ensure the fence can handle added weight.
3. Clean the fence – Remove debris, dirt, old paint or stain, rust, etc. so new materials adhere properly.
4. Mark the fence posts – Use a level to mark the desired new height all the way around.
5. Remove detachable fence panels if possible – This provides easier access for working.

Taking the time to properly prepare the existing fence will help ensure your height extension project goes smoothly and lasts over the long term.

What techniques can be used to extend the fence vertically?

There are a few different ways to add height to an existing fence:

1. Add brackets or fence extensions

Special fence extension brackets can be mounted to existing posts. Then new boards or panels are attached to the brackets. This adds height while preserving the fence’s framework.

2. Install new posts and panels

For a more substantial increase in height, new, taller posts can be anchored adjacent to existing posts. New fence panels spanning the taller posts are attached to extend the fence up.

3. Stack additional materials

Some fences like chain link can have new framework installed atop the original. Additional privacy slats can also be stacked to increase privacy and height.

4. Replace with taller panels

One straightforward option is to detach and replace existing panels with new, taller panels spanning the original posts. This completely refreshes the fence.

The best technique depends on the existing fence, desired height increase, budget, and DIY skill level. Many homeowners choose to have a professional install taller panels or posts for more complex projects.

How much height can you reasonably add to a fence?

Most standard fences can accommodate the following height increases:

Existing Fence Height	Recommended Height Increase
4 feet	12-18 inches
5 feet	12-24 inches
6 feet	12-36 inches

Extending a fence too high can lead to excessive wind load and structural issues. Limit height increases to 3 feet or less, and consult your local building codes.

What are the costs to increase fence height?

Average costs to add fence height include:

• Fence extension brackets – $5-$20 per bracket
• Additional boards or pickets – $3-$8 per linear foot
• New posts and panels – $25-$50 per linear foot
• Privacy mesh or slats – $1-$5 per square foot
• Professional installation – $40-$70 per hour

Get quotes from at least 3 contractors and evaluate DIY vs. pro install. Extending a 20 linear foot wood fence 1 foot taller could cost $200-$800 or more.

What are the key steps for safely DIYing fence height extension?

Attempting to increase fence height as a DIY project requires careful planning and execution:

1. Research permit requirements – Many municipalities require permits for fence modifications.
2. Use proper protective gear – Gloves, eye protection, etc. for safety.
3. Buy quality materials – Don’t cut corners buying inferior boards, brackets, etc.
4. Reinforce existing posts – Opt for metal post spikes or concrete backfill for added stability.
5. Work carefully with power tools – Use saws, drills, nail guns, etc. cautiously to avoid injury.
6. Follow all manufacturer instructions – For items like fence brackets and purchased panels.
7. Check your work – Inspect for wobbly posts, gaps, sharp edges etc. after completing install.

Consider having a professional handle the project if you lack experience with fence demolition, construction, or using power tools.

What are the key maintenance tips for extended fences?

Proper ongoing maintenance is essential for an extended fence to stay in good shape:

• Inspect annually – Check for damage, decay, and stability issues.
• Reinforce as needed – Add support braces, backfill posts, tighten hardware.
• Clean regularly – Power wash vinyl, metal, composite fencing.
• Seal wood fences – Apply protective stain or sealer every 1-2 years.
• Trim vegetation – Clear trees/shrubs to prevent growth from destabilizing the taller fence.
• Promptly repair issues – Fixing small problems early prevents bigger headaches.

Proper maintenance helps maximize the longevity of your fence height extension and preserve security and aesthetics.

Conclusion

Extending the height of an existing fence is a worthwhile project for many homeowners seeking added privacy and security in their yard. With prudent planning, high-quality materials, proper installation, and routine maintenance, fence height extensions can enhance the functionality and appearance of your outdoor space for years to come.
