Fence Replacement Calculator: Removal and New Fence Costs

Replacing a fence is not quite the same job as installing one on an empty lot. The old posts must come out or be assessed, debris needs a destination, and the new fence may not follow the exact same line. This calculator separates removal from the new work so an attractive price per foot does not hide a missing disposal charge. All starting prices are illustrative allowances, not verified US averages.

Measure the replacement scope before comparing bids

Measure the actual fence run in linear feet, not the yard area. Mark each gate, corner, change in height and stretch with difficult access. Ask whether a quoted run includes gate openings; match the calculator length to the contractor’s pricing convention so the gate is not billed twice.

Replacement cost formula

Subtotal = length × (material rate + installation labor rate + removal/disposal rate) + installed gates + fixed footing-repair and fee allowance. Total = subtotal × (1 + contingency percentage / 100). Installed gate prices already include gate labor; do not add it again. Gate counts are rounded up to whole gates.

Worked example: replacing 150 feet of fence

• New fence materials: 150 ft × $18 = $2,700.
• Installation labor: 150 ft × $12 = $1,800.
• Removal and disposal: 150 ft × $4 = $600.
• One installed gate: $350.
• Footing repairs, survey and fees allowance: $700.
• Subtotal: $6,150. A chosen 10% contingency adds $615; planning total: $6,765.

These numbers demonstrate the arithmetic. Replace every rate with prices for your chosen height, material and site. Set removal to zero only when it is excluded from your scope or explicitly included elsewhere.

Can existing posts and concrete footings be reused?

Sometimes, but matching the new fence to old posts can be a false saving. Ask the installer to check rot, corrosion, plumb alignment, embedment, spacing and suitability for the new wind load. A sound-looking post above ground can be damaged at grade. Reuse should be confirmed on site, not assumed from this estimate.

What to put in the written contractor quote

• Material, height, board spacing, post type and hardware specifications.
• Removal of old panels, posts and concrete; hauling and disposal fees.
• Access arrangements, landscaping protection and cleanup.
• Gate width, latches, hinges and installation labor.
• Property-line verification, HOA approval and responsibility for any permit.
• Treatment of hidden footing problems and a written change-order process.

Repair versus replacement

If damage is limited to a few panels and the remaining posts are sound, price a repair before replacing the full run. Repeated leaning posts, widespread rot or a change in fence layout may favor replacement. Do not assume a replacement is permit-free: check local height, corner visibility, easement and pool-barrier rules. Arrange utility locating before digging.

Frequently asked questions

Does the replacement total include removing concrete?

Only if your removal rate or fixed allowance covers it. Ask for explicit pricing for extracting and hauling concrete; buried obstructions can change the scope.

Is labor already included in the material rate?

The replacement tool expects separate material and labor rates. If you enter an installed price under materials, set labor to zero and check that gates and removal are not already included.

Are permits and surveys always necessary?

No. Requirements depend on the property and jurisdiction. Enter a confirmed fee or a clearly labeled allowance, and verify the property line rather than relying on the old fence position.
