How a chain link fence fits together
Knowing the parts makes any repair quote easier to read:
- Terminal posts at the ends, corners and gates, heavier than the rest. The fabric is stretched between them.
- Line posts in between, which hold the fabric up but carry little tension.
- The top rail along the top, in sections that sleeve into each other.
- Tension bars and bands that clamp the fabric to the terminal posts.
- The fabric, woven from wire in a diamond pattern, and the ties that clip it to the posts and rail.
Common repairs and how each is done
Sagging or loose fabric. The tension has gone. The fabric is re-stretched from a terminal post with a fence stretcher, then re-clamped and re-tied, often without any new parts.
Holes and cut sections. The damaged part is unwoven by removing a single twisted wire, and a new piece of fabric is woven in the same way. Done well, the splice is hard to spot.
Bent top rail. Usually from a fallen branch. The bent section is cut out and a new length slides into the sleeves at each end.
Leaning or broken posts. Line posts can be reset or replaced one at a time. Terminal posts hold the whole run's tension, so they need deeper, heavier footings, and the fabric is released before they are worked on. The method for resetting a post is the same as in our fence post repair guide.
Sagging gates. Worn hinges, a bent frame, or a gate post that has leaned. Adjusting the hinges and adding a diagonal brace across the gate frame fixes most of them.
What chain link fence repair costs
| Job | Typical cost |
|---|---|
| Mesh (fabric) repair Holes, tears or cut sections spliced out | $75–$300 |
| Post replacement Line post; corner and gate posts cost more | $100–$250 |
| Gate repair Hinges, latch or sagging frame | $100–$400 |
| Rust treatment Depends on how much of the fence is affected | $75–$300 |
| General repair, by length | $10–$20 / linear ft |
| Most repairs, overall | $200–$800 |
Matching old chain link
New fabric has to match the old in three ways: mesh size (the diamond opening, commonly 2 inches on home fences), wire gauge (thickness), and height. Galvanized fabric can be matched almost anywhere, and black or green vinyl-coated fabric is widely available too. Very old fences with unusual heights or mesh sizes are the only real matching problem.
Repair or replace?
Repair makes sense when the problems are local: one hole, a few posts, a bent rail. Replacement starts to make more sense when the fabric is rusted through along most of its length, when several terminal posts have failed, or when you would be replacing more than roughly a third of the fence anyway. Getting a fixed quote for both is the easiest way to decide. For wood and vinyl fences, see fence repair cost and vinyl fence repair.
Common questions
Can you repair a chain link fence yourself?
Small repairs, yes: re-tying loose fabric, replacing ties, adjusting a gate hinge. Re-stretching fabric and splicing new mesh are doable with a fence stretcher and some patience. Terminal posts are best left to someone with the tools, because they hold the tension of the whole run.
How do you tighten a sagging chain link fence?
Release the fabric at a terminal post, pull it taut with a fence stretcher or come-along, then reinstall the tension bar and bands and re-tie the fabric to the line posts and top rail.
Can I patch a hole in chain link?
Yes. The damaged section is unwoven and a matching piece of fabric is woven in, so the repair becomes part of the fence rather than a patch wired over the top.
