I tried a product called Fencemender years back, and it is still keeping my fence straight to this day. Below is an article that describes it a little better for you:
"Repairing a broken fence post or fixing a rotten post can be done without taking out the old post or fence boards. Many fences sag because their posts rot within a few years of installation and if you go to the trouble and expense of replacing the post or even the whole fence, the posts can rot again in another 5-10 years. We came across a product called Fencemender that works by placing two sleeves down into the concrete or dirt next to the posts. You then nail the sleeves to the post. It is easy to do and takes about 10-20 minutes.
We found that the knock-offs that are on the market don’t have the locking ability of the Fencemender as they tend to wobble and are difficult to place in the concrete as the hammer would slip off while attempting to drive them into the ground. The Fencemender created a fully structurally sound and straight post.
While the do-it-yourself homeowner can easily install the Fencemender, it is worth the handyman’s consideration to think about installing them as a business. An installer may charge between $30.00 to $50.00 per post to replace with a new post. A Fencemender costs between $10.00 to $20.00 with a $30.00 to $40.00 profit for about 10-20 minutes per post. There is an opportunity for anyone thinking about going into the repair business. Adding leaning fence post repair or rotted fence post repair can bring in 10k to 20k a month just for a standard work day. This could be a perfect business for anyone in between jobs or even retired people looking to make some side money.
We found that the company will work with you and contracting discounts are available for larger quantities. It’s really interesting that they haven’t franchised this idea sooner, it seems like such a no brainer. The Fencemender has been around for about 25 years with about 2 million installed in California alone. Why they didn’t venture across the US sooner, we don’t know, but now it’s available and ready to be shipped right to your door. If you are interested, check out this website: www.fencemender.com"
