Get matched with top fencing pros in Rockford, TN

Do you need a permit to build a fence if you are simply replacing an existing fence? Whether you need a permit in this case depends on your local laws and regulations. Most municipalities consider a fence replacement project as being equal to building a new fence, so you likely will need a permit. Check with your local building inspection department or zoning department to see if you need a permit. If you hire a local fence contractor, this pro can take care of obtaining all permits for you.

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.

A chain link fence typically lasts between 15 and 20 years, but with proper maintenance, it can last for 30 years or more. To preserve the fence, it's important to keep the mesh wire tight, which can be done with a come-along tool every 6 to 12 months. Investing in a fence with a galvanized, powder-coated, or vinyl-coated finish can increase its lifespan to 20 to 30 years and reduce maintenance needs, as these coatings provide extra protection against the elements.

In the vast majority of cases, chain-link fences are less expensive than wood fences. Installing a wood fence costs anywhere from 20% to 30% more than a chain-link fence, or an average of $3,100, whereas a similarly sized chain-link fence will average around $2,400. Even with add-ons and additional protective finishes, a chain-link fence is very likely to cost you less than a wood fence. The only exception would be a split rail wood fence, which can cost about half the price of a chain-link fence or less.
