Fence Post Replacement and Leaning Fence Repair in the Greater Toronto Area

New Post Installation or Post Replacement?

People arrive at this page from two directions, with different problems and different budgets. It is worth being clear which one you are.

Setting New Posts and Footings

This is the post-setting side of the work — the structural half of a fence, done as its own job. We install fence posts and footings across Brampton, Oshawa, Mississauga, Toronto and the rest of the GTA.

• Line layout and string-lining so the run is straight and the spacing is consistent
• Utility locates before any digging — mandatory, and arranged as part of the job
• Post-hole digging by auger, with hand-digging where access or services require it
• Concrete footings poured below the frost line, generally around 1.2 m in the GTA
• Post sizing to the fence: 4x4 for standard runs, 6x6 for gates, tall privacy fences and exposed corners
• Terminal, corner and gate posts sized and braced for the load they carry
• Posts set plumb and left to cure before anything is attached

Where Our Post-Setting Work Ends

On a posts-and-footings job we set the posts, confirm alignment and plumb, and hand back a cured, ready-to-build line. Attaching rails, boards, panels or mesh is yours from there — that is the point of the service, and it is why people book it. If you would rather we finish the fence as well, we quote it as a full installation instead.

Toronto-area clay is the usual complication. Compacted clay and rocky pockets slow augering and sometimes force hand-digging, which is why a post-setting quote assumes standard soil unless we have seen the site. Ask whether your quote assumes standard soil — with any contractor.

Post Repair and Post Replacement

The replacement side is the more common call, and it is usually triggered by a lean rather than a break. A post that moves when you push the fence has already failed structurally, even if the wood above grade still looks sound — rot starts at the soil line, where the post stays wet.

Post repair, as distinct from replacement, is worth considering when the post itself is sound but the footing has cracked or the post has worked loose in an oversized hole. In that case the fix is the footing, not the post. Where the post is soft at grade, no bracing or backfill will hold it, and the post has to come out.

We take single-post jobs. One rotten post replaced now costs a fraction of the run of failing panels it will otherwise pull down over the next two winters.

Signs Your Fence Posts Are Failing

Your fence post needs replacement if:

• The fence leans
• The post moves when pushed
• The gate no longer closes
• The wood is soft or rotten near grade
• The concrete footing has shifted
• Panels are pulling away from the post
• The same section keeps needing repair

Post Replacement Process

A typical post replacement involves:

• Inspecting the damaged post and nearby fence sections
• Disconnecting reusable panels or rails
• Removing or working around the old post and footing
• Installing the replacement post
• Resetting rails, panels, or gate hardware
• Checking alignment and stability

Concrete Footings and Frost Movement

In Southern Ontario, we plan fence posts around frost movement and drainage. If the footing is shallow, cracked, loose, or poorly drained, the fence will keep moving after a repair that only fixes the lean. We address the structural cause, not just the visible lean, so the fix holds.

Post Replacement vs Fence Repair

Fence repair is the broader category: panels, rails, pickets, chain-link fabric, storm damage, and smaller structural fixes. Post replacement is narrower and more structural. It focuses on the part of the fence that carries the load and keeps the run upright.

If one post failed and the panels are reusable, targeted post replacement preserves the rest of the fence. If several posts are soft at grade, the fence leans along a full run, or the same area keeps failing after winter, a larger rebuild is usually the better long-term repair.

4x4 vs 6x6 Fence Posts

Standard 4x4 posts hold up fine on most straight runs. Gates, taller privacy fences, heavy wood styles, and exposed fence lines put more load on the post, which is why they call for a 6x6 instead. We size the post to your fence height, material, gate size, soil conditions, and exposure, so it matches the job.

The same logic applies to chain-link posts and gate posts. Chain-link terminal posts (the posts at the ends and corners) and gate posts carry more load than line posts (the posts spaced along a straight run) and usually need deeper footings, especially at wider openings. We size the post to the fence type and the gate it supports so the structure stays stable over time.

What to Check Before Requesting a Post Quote

Photos and a few observations help us scope the right fix before a site visit.

• How many posts are leaning, loose, cracked, or rotten
• Whether a gate is attached to the failed post
• Whether panels or rails still look reusable
• Whether the post failed after winter, wind, impact, or gradual rot
• Whether old concrete is visible or lifting out of the ground
• Whether access is tight, landscaped, sloped, or blocked by sheds or decks

Old Fence Removal and Disposal

Once posts have failed across several runs, the most practical fix is often to clear the section entirely and rebuild. Where it is included in your quote, we strip the affected panels, extract the failed posts and footings, and ready the line for new posts to be set.

• Detaching panels tied to failed posts
• Extracting leaning or snapped posts
• Digging out old concrete footings
• Tidying the line ahead of new post-setting
• Coordinating debris haul-away and site access
• Advising when a partial reset beats a full replacement

Posts on a Boundary Line Between Two Properties

A failing post on a shared boundary is still quoted per post. If three posts along a 200-foot line have gone, that is the scope of the job, and the rest of the run can stay where it is.

Adjoining owners can each be quoted on their own. Where two neighbours are splitting a boundary fence between them, each receives a separate quotation covering the posts on their side of the arrangement.

A few points are worth settling with the neighbour first: whether the posts sit on the line or inside one property, who is authorising the dig, whether either side objects to panels coming off and going back on, and how the bill is being divided. Utility locates are arranged by us either way, whichever side the post sits on.
