Good fences make good neighbors. That's why you want to keep your fence in good condition. It's relatively easy to take a few minutes once a month to check your fence line and make sure it's in good repair. If it isn't, here's what you can do.
A fence is a property enclosure made of pickets, boards, rails, chain-link fabric, or other materials. Wood is the most popular fencing material and one that takes on many forms, including privacy, rail, and picket. Wood is also the easiest fencing material to work with. Chain-link fencing, if installed correctly, is virtually maintenance free.
To replace a wooden fence post:
Check for wooden post rot by removing dirt around the bottom with a trowel and using an old screwdriver to probe the wood. Replace if the wood is soft.
Brace the post to keep it in position while you remove the rotten post.
Disconnect the rails and siding from the post.
Dig out the old post and any concrete holding it in place.
Prepare the post hole for the new post by lining it with gravel and, as needed, preparing concrete.
Install the replacement post, using a level to make sure the post is plumb on two adjoining sides. Fill the post hole with gravel or cement as needed.
Once the post is firm (concrete is dry), attach the rails and siding to the new post.
To straighten a leaning post or sagging gate:
Install an eye screw at the highest point on the leaning post or the gate frame.
Install another eye screw diagonally from the first.
Install a turnbuckle between the two eyes and tighten it until the post is plumb or the gate frame is square.
To reinforce a sagging fence or gate frame:
Identify the best location for installing a metal support, typically on corners.
Select a galvanized metal support bracket for installation on the fence or gate frame. Many sizes and shapes are available at hardware stores.
Brace the fence or gate in the position you want it to stay, then install the metal support using screws or nails.
To mend a chain-link fence:
Identify the area that needs to be replaced.
Stretch a rope from one side of the damaged area to the other and pull it taut to relieve pressure on the fabric.
Undo the fabric twist at the top of either side of the damaged fabric.
Remove the damaged chain-link fabric.
Install replacement fabric of the same size and width.
Use pliers to tighten the twists at the top of the fabric.
