Fence replacement, decided at the posts you already have

A replacement is not a new fence with a demolition line item. It is a choice about whether the posts can carry another generation of panels — and that choice is made underground, before material is ordered. We match you with crews who dig first and quote second.

In short

What is fence replacement?

Fence replacement is the removal of a failed or outdated run and the building of a new one on the same or a corrected line. The decision that drives cost and outcome is whether existing posts can stay. Sound posts with failed panels is a panel job. Posts that rock, rot at grade or sit in cracked collars means full tear-out — and that is most of the work.

Triggers

Signs you need fence replacement

You have repaired the same sections twice and the next posts are already soft at the soil line
The fence leans in waves rather than at a single panel — posts aging out together
Panels still look acceptable but every gate and corner moves when you push
Material is so mismatched from prior patches that a partial fix will never look finished
You are changing height, style or material and the old posts cannot carry the new load or spacing
Storm damage took out a long run and the remaining posts are the same age and species
An HOA or buyer inspection has flagged the fence as end-of-life rather than repairable

The job

How fence replacement actually works

Walk and test every post before anyone prices panels

A replacement quote written from the street is a guess. The crew should push each post at the top, probe at grade, and note which collars are intact. That map decides reuse versus full rebuild.

Watch for: A single linear-foot price with no post assessment. You are being sold a full rebuild by default, or a panel swap that will fail on bad posts within a season.
Decide reuse, sister, or pull

Posts that are solid, plumb and set deep enough for the new panels can sometimes stay. Borderline posts get replaced selectively. Failed posts come out with their concrete — which is labour, spoil and disposal, not carpentry.

Watch for: Leaving rotten posts and cladding them with new boards. The fence looks new until the first wind event. Also watch for "resetting" a post that has already failed at grade — that is a temporary brace sold as a rebuild.
Settle the line while the old fence is still up

Replacement is the moment when an inherited wrong line either gets corrected or gets rebuilt in permanent materials. Find pins or commission a survey before tear-out if there has ever been doubt.

Watch for: Following the old fence without checking. Rebuilding an encroachment resets the problem for the next owner — and for you if a neighbour surveys next spring.
Tear-out: panels first, posts and collars second

Panels and mesh come off quickly. Posts set in concrete collars are the slow work — excavation, breaking out or pulling collars, hauling spoil. Disposal of treated timber is handled as its own stream in many areas.

Watch for: A quote that prices removal as a flat day rate with no mention of collars. Buried concrete is where the change order lives.
Utility locates and private lines on a known line

Even on a replacement, post holes land in the same corridor as the old ones — and private irrigation, landscape lighting and pool feeds often run parallel to the fence.

Watch for: Skipping locates because "we know where the old posts were." The old posts are exactly where prior damage already happened.
Build the new run to the same standards as a first install

Once posts are set (or reused and verified), panels, rails or mesh go up; gates last. Gate posts still need to be heavier or deeper than line posts even on a replacement.

Watch for: Reusing a line post as a gate post because it is "already there." The swinging load is what failed the old gate; repeating the structure repeats the callback.
Handover: warranties split, and the old line documented

Material and workmanship warranties remain separate. Photograph the finished line relative to any pins or markers, especially if the line moved even slightly from the old fence.

Watch for: No written note of what was reused versus replaced. When a post fails in year two, you want to know whether it was a new set or a kept one.

Money

What does fence replacement cost?

Replacement is priced by linear foot plus tear-out. Reusing sound posts drops the bill; pulling every collar raises it more than panel material does. Gates, corners and slope still add disproportionately. Get reuse and removal broken out, not one blended number.

Straight answer

When fence replacement is the wrong call

Everyone else ranking for this is paid when you say yes. Here's when you shouldn't.

Only a few posts move and the rest are solid. That is repair territory. Paying for full replacement to fix three posts is how people overspend when a selective post-and-panel job would do.
You have not checked the property line. Replacing a fence on the wrong line is more permanent and more expensive than living with an ugly old one for another season while a surveyor marks pins.
The HOA has not approved the new style or height in writing. Replacing like-for-like sometimes still needs approval; changing material almost always does. Build first, fight later is a losing sequence.
You plan to sell within months and the fence is merely tired, not failing. Buyers discount obvious hazards; they rarely pay back a full replacement. Cosmetic refresh or targeted repair may be the rational spend.
Drainage, not the fence, is the real complaint. A solid replacement across a flow path can worsen yard water. Fix grade first if water is why you hate the fence.
You want to keep the posts but change to a much heavier or taller system. Reuse only works when the remaining posts can carry the new wind load and panel weight. Hope is not engineering.

Straight answer

Can I do this myself?

Reasonable to DIY

Testing every post and mapping soft spots at grade before you call anyone
Photographing the existing line relative to house corners, sidewalks and neighbour fences
Reading HOA rules for replacement-as-new versus repair exemptions
Pulling loose panels yourself only if posts are staying and the line is safe
Getting a utility locate before any DIY digging near the old posts

Call a licensed pro

Extracting posts set in concrete collars
Any run where reuse versus full rebuild is unclear without excavation
Boundary uncertainty — surveyor first, fence crew second
Pool barriers and any fence with a safety function
Long runs with mixed post conditions where selective replacement needs sequencing

Before you sign

What to check when hiring for fence replacement

Which posts are you reusing, and how did you decide?

You want a post-by-post answer, not "we will see on the day." Reuse is where the quote flexes.
Is tear-out of collars included, and how is spoil disposed of?

Buried concrete and haul-away are the classic underbids on replacement.
Are we rebuilding on the old line or verifying the boundary first?

If the answer is only "follow the old fence," understand the risk you are accepting.
How do gate posts differ on the new run?

Replacement projects still get line-post gates. Ask explicitly.
If we change material, do the old post spacing and height still work?

Vinyl and wood panel modules do not always match legacy post centres.
What is warranted on reused posts versus new work?

Many warranties exclude kept structure. Get that in writing before you choose reuse to save money.

FAQ

Fence Replacement — questions people ask

Still have a question? Talk to our team →

Can I replace fence panels and keep the posts?

Yes, when the posts are sound, reasonably plumb and appropriate for the new panels. Push each post at the top and probe at grade. If several move or feel soft at the soil line, keeping them turns a replacement into a staged failure. Material change matters too: new panel systems often want different spacing or post size than what is in the ground.

Is fence replacement different from fence installation?

The build sequence is similar once the line is clear. The difference is tear-out, the reuse decision, and the temptation to rebuild an inherited wrong line. Installation pages lead with surveys and approvals for empty ground; replacement leads with what is already underground and whether it deserves another decade of service.

Should I replace the whole fence or only the bad sections?

Count failing posts and look at visual match. A few isolated failures on an otherwise solid, matching run is repair. Widespread post movement, or a front elevation that will never match new stock, pushes toward full replacement of that run. Chasing section repairs year after year usually exceeds a planned rebuild.

Do I need a permit to replace a fence that is already there?

Often yes if height, location or material changes, and sometimes even for like-for-like — it is local. HOA rules frequently treat replacement as a new application. Ask the building department and the association before ordering materials, not after the old fence is in a dumpster.

What happens to the old concrete in the ground?

It has to come out if the post is being replaced in the same hole, or the new post is set beside it — which shifts the line slightly and sits in disturbed soil. Pulling collars is labour-heavy. Ask how the crew handles collars and where the concrete goes; both should appear on the quote.

Can replacement fix a fence that is on the neighbour's land?

Only if you move the line. Replacing in place freezes the encroachment in new materials. If there is any chance the fence is over the boundary, survey and negotiate before tear-out. That conversation is cheaper while the old fence is still standing than after you have invested in a new one.
