Aluminum is among the longest-lasting fencing materials, with a lifespan of 30 to 50 years or more. One of the reasons it lasts so long is because aluminum is highly resistant to rust and corrosion. You can help prolong its lifespan by keeping it free of vegetation and cleaning it every few months with a hose and mild soap.

The regulations for pool fence heights vary by state, so be sure to research what the legal, minimum height is in your area before purchasing or installing a fence. Though every region is different, generally a pool fence must be at least 4 and ½ feet high. If you’re unsure whether you need a fence around your pool, and how high that fence should be, contact a local pool enclosure expert to help you successfully, and safely, move forward.

There are several options for post materials. Depending on where you live, the weather, and what kind of durability you want, you can choose from wood, steel or concrete posts for a barbed wire fence. Your corner and end posts should be especially strong in order to maintain the structural integrity of the fence. 

Ideally, when you replace a fence post, you should also replace the concrete footing. The concrete bonds to your new post, creating a secure base. If you install a new post into old concrete, it won’t be as sturdy.

That said, it is possible. Sometimes the post will lift right out of the concrete. If not, you can use a high-lift car jack to try and lift the pole out of the footing. Put the new post into the same hole and backfill it with fast-setting concrete. Keep in mind, this won’t work well for metal posts.
