Eventually due to time and elements, every fence will have to be repaired. When faced with having to repair a fence, the first decision is whether to repair it or replace it. With the tricks for repair here, you make a fence as good as new while actually changing very little wood or metal.
The first step in repairing a fence is to remove the fencing or rails if they will get in the way of the repair. You can remove the fencing with a pry bar, or cut out the damaged section with a handsaw. When repairing a post, remove the fencing and rails connected to the post. Once the repair is completed, replace fencing and rails with new nails driven into new nail holes.
Scrub wooden fences with a fiber brush and a mild detergent solution to remove most stains. For tougher stains, add 1 to 2 cups of bleach to a bucket of warm water. Wear gloves and safety goggles aways when working with strong cleansers.
Clean vinyl fences with a sodium-bicarbonate-base cleaner. Bleach may stain the fence while cleaning. Also, use a cloth instead of a brush so you don't scratch the surfaces of the fence.
Clean metal fences with a wire brush by scrubbing away old paint, dirt, and rust from metal posts. Most stains can be taken care of with a cup of strong household dtergent in a gallon of warm water.
Reinforce rail ends by fastening 2x4 cleats under the rail to the posts. Secure the cleats with galvanized 10d nails (3-inch) nails. You also can reinforce a third rail using this method. Add a sister rail to bolster a damaged rail. It can span the entire rail or just part of it, depending on the damage. Clamp the sister rail under or on top of the original, then drill holes through both rails and secure them with 3/8 x 4-inch carriage bolts. Remove the clamps.
Straightening wood posts requires digging around the post until you reach the bottom of it. Put aside the soil you remove for backfilling around the post. If the post is set in concrete, use a sledgehammer and break up the concrete. Remove the pieces and straighten the post. Add new concrete.
Your new fence will look like you have worked hard on it for years.
