Hamilton fences fail in a predictable way. A pressure-treated fence from the 1980s or 90s on the Mountain starts to lean one post at a time after a wet spring, the gate stops latching, and then a windstorm takes a section down. Most of these can be repaired. Here is what each fix costs in Hamilton, how to tell a repair from a replacement, and how the City handles a fence you share with the house next door.
2026 fence repair prices in Hamilton
| Repair | Typical 2026 price |
|---|---|
| Brace a leaning post that is still solid | $150 - $300 per post |
| Replace a rotted or snapped post | $250 - $450 per post |
| Dig out a heaved post and reset it below frost | $300 - $500 per post |
| Replace broken boards or pickets | $15 - $30 per linear foot |
| Replace 3 or 4 cedar panels | $400 - $900 |
| Rebuild a sagging gate | $200 - $600 |
| Swap a vinyl panel | $150 - $400 per panel |
| Chain link: re-stretch, splice, new top rail or post | $150 - $500 |
Prices include materials, concrete, hauling away the old wood and cleanup. A single small repair carries a service minimum of about $250 to $400, because the trip, the post hole digger and the locate are the same for one post as for four. If you have a list, book it in one visit. Full detail by material is in our Ontario fence repair cost guide.
Why Hamilton posts lean
Most of the Mountain, from Eastmount to Rymal, and much of Stoney Creek and Binbrook sits on heavy clay that stays wet from March to May. Frost reaches about 1.2 m (4 ft) here. A post set 60 to 75 cm deep in a bell of concrete gets gripped by frozen clay and lifted a little each winter, and it never settles back the same. That is a heave, and the fix is to dig out the old concrete and reset the post below frost, not to brace it.
Rot is the other cause. Pressure-treated posts rot at the soil line, where wood stays wet, and concrete mounded above grade holds water against them. In the lower city, older fences on narrow lots and laneways often have posts that were never set in concrete at all. Push a screwdriver into the post just below the soil. If it goes in easily, the post is done.
Repair or replace: the five post rule
- One or two leaning posts, wood still hard: brace or reset them.
- One or two posts soft or snapped: replace those posts.
- Three or four soft posts: probe the rest before deciding.
- Five or more rotted posts, or a fence over about 15 years old: replace. A new pressure-treated fence runs $35 to $60 per linear foot installed, cedar $50 to $90, plus $5 to $12 per foot to remove the old one. Our Hamilton fence installation page has local pricing.
Shared fences: Hamilton uses fence-viewers
A fence on the property line belongs to both owners, and so does the repair bill. Talk first, agree the work and the split in writing, and check your survey for the line. If you cannot agree, Hamilton has not replaced the provincial process with its own by-law, so Ontario's Line Fences Act applies. Either owner can ask the City Clerk for fence-viewers. Three viewers attend, look at the fence and issue an award that says who does which part of the work and who pays. Under Hamilton's By-law 25-122:
- The applicant pays a $300 deposit when asking for a viewing.
- The City charges a $100 administrative fee per viewing.
- Each viewer is paid $90 per viewing plus mileage, and the viewers decide whether you, your neighbour or both of you cover it.
- No viewings are scheduled from November 1 to March 31, so a dispute in the fall waits until spring.
Fence-viewers do not decide where the property line is. If that is the argument, you need a surveyor, not a viewing. An owner unhappy with the award has 15 days to appeal. In practice, knowing the process exists settles most Hamilton disputes before a viewer is ever called.
Trees, pools and permits
When a tree falls on a line fence, the Line Fences Act puts removal and repair on the owner of the land the tree stood on. Pool owners have a separate duty: a fence that is part of a pool enclosure must still meet Hamilton's Pool Enclosure By-law 16-184 after the repair, including a self-closing, self-latching gate. Repairing a fence at its existing height does not need a permit. If the repair raises it, Hamilton's Fence By-law 10-142 caps residential fences at 2.0 m, and at 0.9 m within 3.0 m of the front lot line. Every new post hole starts with a free locate through Ontario Dig Authority.

Frequently asked questions
How much does fence repair cost in Hamilton?
Most repairs cost $150 to $1,500 in 2026. A post brace is $150 to $300, a replaced post $250 to $450, and 3 or 4 cedar panels $400 to $900.
How much does it cost to replace one fence post?
About $250 to $450 in Hamilton, including digging out the old concrete, a new post set below frost and reattaching the rails.
Does my neighbour have to pay half the fence repair in Hamilton?
Usually you split it by agreement. If you cannot agree, either owner can ask the City Clerk for fence-viewers under the Line Fences Act, who decide how the work and cost are shared.
How much does a fence-viewer cost in Hamilton?
The applicant pays a $300 deposit and a $100 fee per viewing. Each of the three viewers is paid $90 plus mileage, charged to one or both owners as they decide.
Do I need a permit to repair a fence in Hamilton?
No, not to repair a fence at its existing height. Raising it must stay within Fence By-law 10-142, and pool enclosure fences must still meet By-law 16-184.
Who pays when a tree falls on a fence?
Under the Line Fences Act, the owner of the land where the tree stood removes the tree and repairs the fence.
