Removing an old deck is often treated like a small line item, but on a large or elevated structure it can become a serious part of the project budget. Labor, disposal, access, railing, stairs, concrete footings and the material being removed all affect the final price.
Quick answer: 2026 consumer cost data from Angi places deck demolition and removal at about $5 to $15 per square foot in many cases. A simple ground-level deck with easy access can land toward the lower end, while elevated decks, difficult access, heavy railings and more complicated disposal can push the cost higher.
2026 Deck Removal Cost by Size
Using the broad $5–$15-per-square-foot demolition range as a planning reference:
| Deck size | Square feet | Broad demolition range |
|---|---|---|
| 12 × 16 | 192 | $960–$2,880 |
| 12 × 20 | 240 | $1,200–$3,600 |
| 16 × 20 | 320 | $1,600–$4,800 |
| 20 × 20 | 400 | $2,000–$6,000 |
These are rough planning numbers, not quotes. They do not automatically include new construction, repairs to the house after demolition, permits, landscaping restoration or special disposal conditions.
What Makes Deck Demolition More Expensive?
- Elevation: second-story decks require more controlled dismantling and handling.
- Stairs and landings: long stair runs add material, fasteners and labor.
- Railings: aluminum, composite or cable systems add more components to remove.
- Difficult access: narrow side yards, steep slopes and long carry distances slow disposal.
- Heavy framing: large beams and multi-level framing take longer to dismantle.
- Footings: removing concrete can add machine time and hauling weight.
- Material type: disposal costs vary by wood, composite, PVC, metal and mixed construction debris.
Full Demolition vs. Surface Removal
Not every project needs a full teardown. If the structure is still sound, removing only the decking, fascia, stairs and railing may allow the frame to be reused. That is the basis of a resurfacing project.

Should Footings Be Removed?
If a new deck will be built in the same general area, the old footings should be evaluated rather than automatically reused or automatically removed. Location, size, condition, depth and the new structural plan all matter. Reusing a bad footing to save demolition money can create a much more expensive problem later.
Can You Save Money by Doing the Demolition Yourself?
DIY demolition can reduce labor cost on a simple deck, but it also creates safety and disposal issues. Elevated framing, heavy beams, attached ledgers, electrical wiring, gas lines, concrete and unstable structures are not good places to learn by trial and error.
If the deck is attached to the house, the demolition plan should also protect siding, doors, flashing and the wall behind the ledger.
Removal Cost Is Only One Part of Replacement
Angi’s current 2026 composite-decking data also lists demolition around $5–$15 per square foot as an add-on when replacing an existing deck. Once demolition is finished, the replacement budget still needs to cover footings, framing, decking, railings, stairs, permits and labor.

Questions to Ask Before Accepting a Demolition Price
- Does the price include hauling and disposal?
- Are railings and stairs included?
- Are concrete footings being removed or left in place?
- Will the contractor protect the house where the ledger is removed?
- Does the quote include cleanup and magnetic fastener pickup?
- Who handles dumpsters or dump fees?
- Is landscaping repair included?
- What happens if hidden structural damage is found at the house connection?
Bottom Line
A broad 2026 planning range of roughly $5–$15 per square foot is useful for deck demolition, but access and complexity matter as much as square footage. The most important decision is whether the deck truly needs full removal or whether a sound structure can be resurfaced instead.
