Dock Demolition + Replacement: Process and Cost

Demo of a typical 12×20 single-slip dock runs $3,500–$7,500, and a comparable new build runs $25,000–$50,000, so demo-plus-standard-replacement lands $30,000–$58,000 on most jobs. Add electrical, a lift, a cover, or associated seawall work and full-scope projects regularly reach $60,000–$120,000. Consolidating it all into one mobilization saves 12–25% versus piecemeal contracting.

On most regulated lakes, yes. TRWD requires shoreline-disturbance disclosure even for a like-for-like rebuild; AMWA wants pre-notification and inspection access; UNRMWA wants written confirmation that all materials are removed, not buried or pushed into the lake. Demo permit fees run $200–$800, and we manage them as part of the project.

About 4–6 working days for a typical 12×20 single-slip dock with a 3-person crew, weather permitting — day one for electrical disconnect and lighting removal, then decking, then framing and piling extraction. The bigger schedule question is coordinating the demo with the new build so it all happens in one mobilization rather than leaving the site idle between phases.

A dock hits the demo threshold when three or more of these are true: pilings are leaning or shifted from their original alignment, framing shows rot or fastener pull-out across multiple bays, decking is failing in a pattern that points to sub-structure problems, the dock is over 30 years old with no major rebuild history, or there's storm damage your insurer declined to cover. One or two of those, and spot-repair is fine. Three or more, and full replacement is the more cost-effective call.

Day one is electrical disconnect and lighting removal. We trip all the circuits at the house panel, then pull the fixtures, conduit, and any sub-panels at the dock and inventory them. Anything reusable gets set aside and anything corroded gets boxed for disposal.

Pilings come out during days three through five, after the framing has been pulled off in sections. We extract them with an excavator using a piling clamp, or sometimes vibrate them free for clean reuse if a contractor is taking them as trade. Sound, plumb pilings often have life left, and reusing them shaves real money off the demo.

Treated lumber and composite decking don't go to a regular Texas landfill without proper handling and documentation. Only the untreated wood goes to the burn pile; treated and composite material goes to a disposal pile that has to reach a receiving facility legally. Pushing old material into the lake has happened often enough that the authorities wrote rules against it, and it's both illegal and a fast way to get a contractor's authority relationship revoked.

Because legal disposal of treated wood, composite decking, rusted hardware, and electrical waste is a real cost that runs $800 to $2,500 depending on volume and the receiving facility. Quotes that bury that in 'miscellaneous' or skip it are quoting an incomplete job, and you pay for it at the end one way or another. UNRMWA, AMWA, and TRWD all care where the material goes, so we line-item it and document where it went.

Consolidating everything into one continuous mobilization saves 12 to 25 percent versus piecemeal contracting. Doing the dock, lift, and any associated seawall or rip-rap shoreline repair on a single trip means you aren't paying the crew and equipment to come twice. We always quote the full scope when there are obvious adjacent items so you can see the bundled-versus-separate math.

Done poorly, the demo happens, the site sits empty, and a second mobilization weeks later adds cost and leaves you dockless longer than necessary. Done well, the new pilings go in as the old structure comes out in one continuous mobilization, so the crew and equipment aren't paid to come twice. That choreography is also where the 12 to 25 percent savings on demo-and-rebuild actually comes from.

Often yes, because a tired dock is frequently the thing that drags a lakefront listing. A buyer who sees a sound, permitted new dock prices the property as turnkey, while one who sees a failing structure mentally subtracts a full rebuild, usually more than it would actually cost, and negotiates from there. A rebuild done as pre-listing prep is a controlled expense; one discovered in a buyer's inspection becomes a negotiation you're on the wrong side of.

On most regulated lakes, demolition requires its own permit, and most authorities want the demo and the new build covered together. TRWD requires shoreline-disturbance disclosure even when the new dock matches the old footprint, AMWA wants pre-notification and inspection access, and UNRMWA wants written confirmation that all materials are removed. We sequence the approvals so the rebuild can follow the demo without a gap, and we quote both as one scope.
