Delta Wind Fence Repair: When to Patch vs. Replace

By Richard · Published February 4, 2026

Every winter, the Delta winds that come through Brentwood, Oakley, Antioch, and Pittsburg take out a few thousand fence sections across the East Bay. Some of those need a quick panel patch. Others need full replacement. Knowing the difference saves you a lot of money — and from getting talked into work you don’t actually need.

After years of doing fence repair across East Contra Costa County, here’s how I assess every fence I’m called to look at.

The Wiggle Test

The first thing I do at any fence is grab a few posts and try to wiggle them. The post condition is the single most important factor in patch-vs-replace.

• Posts that don’t wiggle at all: Fence is patchable indefinitely as long as panels can be repaired or replaced.
• Posts that wiggle a little: Probably some rot at the base. Replace those individual posts; patch panels.
• Posts that wiggle a lot or move at the base: Major rot. Whole run is on borrowed time.

Most fences I see have a mix. A run of 12 posts might have 9 solid, 2 marginal, and 1 obviously rotten. That’s a clear “replace those three, leave the rest” call.

The Panel Test

Next, look at the panels themselves:

• Pickets that are split or warped but still attached: patchable.
• Sections that have separated from rails: patchable.
• Sections where rails themselves have rotted or cracked: replace the panel.
• Whole-panel structural failure: replace the panel.

The “How Old Is This Fence” Question

I ask every customer how old the fence is, because the answer changes my recommendation:

• Under 10 years: patch where you can; you’ve got a lot of life left.
• 10–20 years: patch and accept that bigger work is coming in 5–10 years.
• Over 20 years: be prepared for “this is the last patch I’ll ever do on this fence.” At some point, you’re spending good money on a fence that’s going to need replacing anyway.

When to Replace Whole Runs

I recommend full-run replacement when:

1. More than 30% of posts fail the wiggle test, OR
2. More than 40% of panels need attention, OR
3. The fence is over 20 years old and significant work is on the table either way.

Below those thresholds, patching wins on cost and on disruption (a panel patch is a few hours; a full run is a multi-day project with the gate possibly out of commission).

What Delta Wind Damage Specifically Looks Like

Wind damage tends to look different from age damage:

• Panels lifted out of fasteners (vs. simply rotted)
• Pickets split along the grain (especially mid-board)
• Whole sections leaning to one direction (vs. random sag)
• Gate posts skewed at the base (gate latch suddenly won’t catch)

The good news: wind damage is usually patchable, because the wind picks on weak points but rarely takes out whole posts unless they were already rotten.

What I Charge for Fence Repair

Patch jobs run from about $150 for a single-panel pickets-only repair, up to about $400 for a panel that needs new rails and pickets. Post replacement runs more — typically $200–$400 per post depending on access, depth, and concrete needs. Full-run replacement is project-priced.

I never quote sight-unseen on fence work. There’s just too much variation.

Hiring vs. DIY

Patching a panel with new pickets is a doable DIY project if you have a few hours and a circular saw. Replacing a fence post is harder than it looks — most DIY post replacements I see fail within 2–3 years because they weren’t set deep enough or weren’t properly braced while the concrete cured.
