We get called out to a lot of fences where the homeowner has already decided they need a whole new one, and roughly half the time they don't. We also get called to fences someone has repaired three times in four years, where replacing it the first time would have been cheaper.
There's a reasonably simple way to tell the difference, and you can do most of it yourself in ten minutes.
The ten-minute self-assessment
Walk your fence line and do these four things in order.
- 1Push every post. Firm pressure at shoulder height. A sound post doesn't move. If it rocks in the ground or the base feels spongy, mark it.
- 2Probe the base. Push a screwdriver into the post at ground level. If it sinks into soft wood, that post is rotting out whatever the top looks like.
- 3Sight the line. Stand at one end and look down the fence. Waves, leans, and dips tell you about posts and footings, not boards.
- 4Count the bad posts. This number drives the decision more than anything else.
The one-third rule
A practical threshold we use: if more than about a third of your posts are failing, replacement is usually the better value.
The reason is labor. Replacing a post means removing the panels on both sides, digging out the old footing, setting a new post, and rebuilding the section. Do that to one post and it's a contained repair. Do it to fifteen and you've paid most of the cost of a new fence while keeping twenty-year-old boards and an old style.
| What you find | Usually the right call |
|---|---|
| A few leaning posts, sound boards | Repair — straightforward and good value |
| Rotted bottom boards, solid posts | Repair, and add a rot board while you're at it |
| Storm damage to one or two sections | Repair, often insurance-eligible |
| Sagging or dragging gate | Repair — almost always hardware or bracing, not the fence |
| Over a third of posts failing | Replace |
| Widespread rot at ground level along the run | Replace |
| Fence is 20+ years old and you dislike the style | Replace — you'll be happier for longer |
Things that are cheap to fix and worth fixing
- A sagging gate. Nearly always hinges, a missing diagonal brace, or a post that has shifted. A proper repair with a braced frame and heavier hinges costs a fraction of a new gate and usually outlasts the original.
- Individual broken or cupped pickets. Minor material, minor labor.
- Loose or pulled rails. Usually fastener failure rather than wood failure.
- Missing post caps. Small item, and they genuinely slow water entry into the post top.
- A graying but structurally sound wood fence. Cleaning and re-staining can make a fifteen-year-old fence look nearly new, and extends its life.
When repair is throwing money away
Be honest with yourself about these. We will be.
- You've repaired the same fence more than twice in three years. The pattern is the answer.
- The original posts were undersized or set shallow. Everything built on them will keep failing, because the root cause is still there.
- The fence no longer suits the property — too short for the dog you now have, wrong style for a renovated house, in the wrong place for a new patio.
- You're selling soon and the fence reads as deferred maintenance to buyers. A patched fence can look worse than a clean new one.
Get an opinion that isn't trying to sell you a fence
Worth saying plainly: a replacement is a bigger ticket than a repair, so there's an obvious incentive to recommend one. Ask any contractor to show you specifically which posts are failing and how they counted. If the answer is a vague gesture at the fence and a replacement quote, get a second look.
Our repair estimates are free, and we'll tell you when a repair is the right call even though it's the smaller job. Steering someone toward an affordable repair instead of an unnecessary full replacement is how we end up being the people they call in ten years.
