Are you looking for a way to enhance the look of your fence? Adding some touches of style can make all the difference, and one inexpensive and straightforward way is through fence post extensions.

Fitting fence post extensions on top of concrete posts don’t have to be complicated or expensive. In this article, we’ll discuss how you can go about adding these beautiful, custom touches to your fence in no time, along with a lot more!


How To Fit Fence Post Extensions Above Concrete Posts?

Fence post extensions are an effective way to improve the safety, security, and visual attractiveness of a fence. Installing fencing extensions can make an otherwise plain fence look taller, stronger, and more stylish.

Fence post extensions above concrete posts can be just as simple as installing them atop wood posts. With a few tools and some basic instructions, anyone can make their fence into whatever they want it to be.

Step 1: Measure the Posts

The first step when fitting your fence post extensions is to measure the height of your existing posts so you know how much space you have to work with. You will need this information when selecting the right size extension for your needs.

Step 2: Select Fence Post Extensions

Once you know the height of your existing posts, select the appropriate fence post extensions for the job. Make sure that you’re choosing ones of appropriate length and that they match existing posts in terms of size and design. For instance, if you have steel posts on top of your concrete ones then make sure your extensions match those details exactly.

Step 3: Remove Existing Fence Panels

Once your area is prepared, remove the existing panels from your fence before proceeding with fitting the post extensions. This will give you much better access to install them safely and securely into place.

Step 4: Cut Posts

Using a saw or power tool like a miter saw or hacksaw blade, carefully cut your posts down to size according to your measured lengths. Be sure that all cuts are made straight and true so they will easily fit into place with no undue strain or pressure on existing fence panels.

Step 5: Pre-Drill Holes

In order for the post extensions to not slip or twist while being installed, pre-drilling holes through both sides of each post at various intervals is important – particularly near where they will connect to concrete posts and fence panels.

Be sure not to drill too deep as this could damage adjacent materials.

Step 6: Connect Posts

Using appropriate smooth metal fixings such as screws or bolts (which should ideally be anti-corrosive grade stainless steel), secure one side of each extension around the base of each concrete post using previously drilled holes as guides.

Then attach the opposite end of the extension onto a brace bar which has been attached at multiple points across existing fence panels at an angle – making sure that none of these attachments exceeds 200mm apart along its length.

Step 7: Finish Installations & Secure Fixings

Finally, once all posts have been securely fixed in place ensure that there is no play between timber panel frames and extension pieces by retightening fixings where appropriate using either hand tools or power tools such as an impact driver/wrench.

Do not over-tighten fixings as this may deform the material itself and detract from the overall structural integrity of fencing installation.

Once complete enjoy increased fencing height without needing to dig out old foundations!

How to Maintain Fence Post Caps?

In order for your fence post caps to maintain their good looks and structural integrity, there are a few maintenance steps you should take periodically. Here’s what you need to know about maintaining fence post caps:

Clean Fence Post Caps Regularly

Cleaning off dirt and debris is the simplest form of maintenance for fence post caps. You can use a bucket of warm water and detergent solution to clean them with a soft cloth or brush before drying them off with a towel or air compressors.

Any build-up or mildew on the surface of the cap should also be removed using either a special cleaner designed specifically for this purpose – or white vinegar mixed with water.

Check For Decay or Rust Damage

You should check your fence post caps at least once every season for signs of decay or rust damage. If you notice any cracking, bending, warping, discoloration, pitting, flaking, etc., then it’s time to replace the old cap with a new one.

To help prevent such issues in the future, use a waterproof sealant regularly on all metal surfaces to create an extra layer of protection that will not only provide protection against water but also extend its life span considerably.

Inspect Fence Post Attachments

Make sure that all screws and nuts used to affix your fence post caps are securely tightened before carrying out any other maintenance work on them.

This is especially important if they have been exposed to harsh elements like rain or snow over time as metal components may become rusted due to moisture infiltration which can lead to weakened attachments that can cause damage further down the line if left unchecked.

As well as checking for loosened screws/nuts it’s also worth giving each one a light greasing (if appropriate) beforehand as this will help reduce corrosion from occurring over time even when exposed constantly outdoors .

Store Fence Post Caps Securely When Not in Use

When winter rolls around it’s always best practice to store your fence post caps somewhere dry when they’re not being used i.e., removing their protective coverings before storing so that no moisture can get inside them while they’re stored away type).

This should be done with regular cleaning too – make sure that no dirt is present on any part of the cap before taking it away!


How Do You Sink A Post In Concrete?

Sinking a post into concrete can be a great way to give your fence or mailbox greater stability. Concrete is strong, and when it hardens around the posts, it creates an extremely secure bond with them. Here’s a detailed guide on how to properly sink a post in concrete.

Prepare the Post

First, you’ll need to make sure that the post is of the correct size for sinking into concrete. This involves measuring out the length of the hole and making sure that the post matches up with these measurements. You also want to make sure that the surface of the post is smooth, without any ragged edges or sharp lumps. Make sure you double-check that everything is in order before continuing.

Digging Out the Hole

Once you’re happy with your post and all its measurements, you’ll need to start digging out the hole where it needs to be sunken into concrete. Using a hand shovel or power auger (for more difficult soil), dig out a hole that is at least 8 inches deep and 3-4 inches larger than your post on each side (measuring width than length).

After this has been done, you should begin creating angles for drainage in both directions along all four sides of the hole.

Filling Out & Smoothing Down The Hole

Now it’s time to fill out and smooth down your hole with gravel. When doing this, be sure to create a layer at least 2 inches thick all over (filling it up within 4-6 inches below ground level).

Once this layer has been created, use your shovel or hands to smooth down every surface within the entire area – both inside and outside of it being sunken into – until achieving an even texture across each surface involved.

Adding Pigment & Reinforcement Bars

If desired, now would be a good time to add pigment powder into your mixture before setting up reinforcement bars around it if they are needed in order for extra safety and stability of what will eventually become your final structure (aka either fence or mailbox).

Make sure these are correctly placed before setting up your form boards against them on two opposite sides – one behind and one ahead so as not to cover your posts as they move up once surrounded by concrete.

Pouring The Mixture In & Removing Excess Air

Now comes carefully pouring in your wet mixed cement while quickly moving around air pockets with help from either trowel or stick depending on preference/limitations encountered at moment; removing excess air left up.


How High Should Fence Post Caps Be?

Fence post caps can range from 3 inches to 8 feet in height, so it is important to consider factors such as property lines and existing obstructions when deciding on the ideal height for your fence post caps.

To provide compliance with local ordinances and build-to-code regulations, it is recommended that the top of your post caps generally be no higher than four feet from the finished grade.

If a property has a mandated minimum spacing alongside yards, these fences typically require less than 4 feet overall height for your post tops.

Likewise, if you have an existing landscaping feature such as raised beds or seating walls that affect overall height measurements, then you will want to make sure that the top edge of your fence does not block visibility beyond those features.

It may even be necessary to reduce the overall height of your post caps so as not to intrude on visibility constraints set by local zoning codes or design guidelines (e.g., HOA).

When selecting materials for fencing applications requiring more than 4 feet in total height above ground plane level (GPL), adding details such as finials at varying heights around 6′ will help achieve both aesthetic value and privacy expectations while still providing necessary visibility cues that are mandated by law enforcement officers.


Is 2 Feet Deep Enough For Fence Posts?

For most fences, burying the posts two feet into the ground is usually adequate — however, there are a few instances where deeper depths may be required. Different types of soil and climate change conditions can play a role in this decision and vary from region to region.

Let us look at a few necessary exceptions for deeper post setting when building your fence.

Hardpan Soil and Heavy Winds

If you live in an area with hardpan soil or have high winds, it is essential to sink those posts three feet deep instead of two.

This would more likely help prevent them from tipping over due to pressure from wind and soil problems. Additionally, sandy soils may require an even deeper setting of posts.

Further research will reveal which type of soil best fits your location and desired outcome.

Making sure your measurements are photographed accurately also helps ensure each post is properly installed according to local code restrictions.

Fences That Contain Large Animals

For especially large-scale animals such as horses or llamas, it is recommended that their enclosures contain 8-foot tall boards attached three feet down into the ground on sturdy posts.

This wide perimeter prevents an animal from pushing through any weak spots or trying to dig out around the base of the post.

It also protects against any possible injury as well as damage from severe weathering that could weaken structural integrity over time.

Quality Materials Play an Important Role Too

No matter which depth you choose for your fence post-installation project, you’ll want quality materials like pressure-treated lumber with galvanized fasteners specifically designed for outdoor use along with top-grade concrete mixes for the footings.

All of this can contribute significantly towards coastal protection against harsh elements like heavy winds off salty bodies of water such as oceans, lakes, and bays.

By using these helpful guidelines when deciding upon what type of materials and depths are necessary for successful fencepost installation projects (as detailed above), builders can rest assured that their fences are secure and stable.




What Are Concrete Post Extensions?

Concrete post extensions are typically made from sturdy steel reinforced concrete blocks, which are designed to slide over existing posts and add more height where needed.

Post extensions can be used for anything from extending the height of fencing posts to building taller support structures that need extra strength and stability.

How Do Concrete Post Extensions Work?

The concrete in the post extension supports the extra weight, giving your build more stability than if you were using just bare metal posts with no reinforcement.

The anchoring support system keeps the concrete firmly planted on the ground so your structure is less likely to become unbalanced or knocked over by wind gusts or other whims of nature.

The steel reinforcement helps create a structure that’s considerably durable, so even if its placement isn’t perfectly level, it won’t warp or sag over time due to minute inaccuracies.

What Can You Use Concrete Post Extensions For?

Concrete post extensions are especially useful when constructing large fences, sheds, or stables as they provide additional support and help keep your build steady.

They can also be used as part of home projects such as pergolas, decks, and patios where something taller may be required but you’d like an enduring solution rather than using temporary solutions like boards and posts purchased from a home store.

Can You Use Regular Concrete Mix with Post Extensions?

No – regular concrete mix should not be used when creating post extensions as it will not hold up under pressure in comparison to true steel-reinforced concrete block mix. The steel-reinforced mix is specifically designed for these types of projects as it provides added strength and durability for your particular application.

Therefore for better results always opt for using actual steel-reinforced concrete block mixes when constructing your own custom post extensions – this will ensure that you get a strong finish every time!

How Deep Should A 7ft Fence Post Be?

After deciding to install a fence around your property, you’ll then need to dig the holes for the fence posts. But how deep should you go? Is there a right answer? It depends on what type of fence you are installing as well as where. Here’s a look at some things to consider when determining how deep a 7ft fence post should be:

Wood Fences

When it comes to wood fences, the deeper the better when it comes to burying the posts. Ideally, they should be buried between two and three feet (24-36 inches) underground. This rule of thumb applies regardless of whether your posts are 4ft or 7ft in length. 

Vinyl/Metal Fences

For vinyl and metal fences, you need only to bury the posts about 18-24 inches into the ground. That’s because these materials tend not to expand or contract with soil conditions like wood does, so their stability isn’t necessarily dependent on a deep hole. 

Cold Climates

In very cold climates where frost is likely and prolonged throughout most winters, fence posts should be buried at least two feet down.

Burying them deep ensures that even if freezing rain precipitation occurs (water freezing at night), moisture won’t make its way high enough into the post holes before it can refreeze.

What Is Fence Capping?

Fence capping is a type of fencing system that has been designed specifically for electric fencing. The main purpose of fence capping is to create an extra layer of safety for the user by containing the charge of an electrified fence within the confines of the capping materials.

This makes it much safer than without the extra protection, as the electrical current running through wiring or chain links can be incredibly dangerous if not handled with care.

Fence capping works by providing a protective layer between any exposed wires and the user or environment. By creating this barrier, it is able to contain any electric shocks or currents that may occur while using an electrified fence system.

Generally speaking, it consists of two different components: PVC-insulated tape and caps that cover any exposed parts of the fence’s wiring or chain links.

Can You Extend Fence Posts?

The easiest way to extend the height of your existing fence post is with a post extension sleeve. These sleeves are available in standard sizes and can easily slide onto an existing wooden or steel post without any extra hardware.

Post extension sleeves allow you to quickly and easily increase the overall height of your fence without having to replace the entire post. Another option is using tension bands that offer adjustable height while also providing extra support where needed.

How To Make Your Fence Posts Last Longer?

If you have an older fence with weak posts, one way to help make them last longer is by reinforcing them with concrete or gravel. To do so, start by digging around each post at least 6-8 inches deep and then fill in the space with either concrete or gravel for extra support.

You should also use pressure-treated wood when constructing a new fence as this type of wood is naturally resistant to decay and helps increase the lifespan of your post significantly.

Once installed, make sure to regularly inspect all posts for signs of wear and tear as well as any structural damage that may require immediate attention.
