An inspection can help answer the questions you were unsure about.
An on-site inspection is needed to assess the wall’s condition. These answers help you explain what you have noticed.

What could your seawall cost?
Published contractor context, not a Naples average or a quote.
One Naples-based contractor publishes Southwest Florida construction and anchor ranges. The calculator applies those ranges to your wall length and keeps repair options separate. You can also enter your own quote.
Repair prices by type
Compare the stated anchor scopes separately. Other repairs need their own assessment and price.
| Work | Amount | What the price covers | Area and source |
|---|---|---|---|
Secondary anchors | $225–$300 | per foot of wall; Supplementing an existing wall; not a full-system replacement. | Southwest Florida [1] |
Full deadman tie-back system | $600–$900 | per foot of wall; Full tie-back and anchor system; not interchangeable with supplemental anchors. | Southwest Florida [1] |
New-wall prices per foot
The publisher does not separate this range by wall material or specify design dimensions and exclusions. It also states that it does not provide flat rates.
| Material / work | Price per foot of wall | Area, included work and source |
|---|---|---|
Construction: material not separated | $400–$900 | Southwest Florida · Advertised construction range; height, embedment and inclusions unspecified. Obtain a property quote. [1] |
50-, 75- and 100-foot examples
Multiply the wall length by the price per foot. These are arithmetic illustrations from the advertised construction range, not estimates for a Naples parcel. Unpriced related work remains additional.
| Material / work | 50 feet | 75 feet | 100 feet |
|---|---|---|---|
Construction: material not separated | $20,000–$45,000 | $30,000–$67,500 | $40,000–$90,000 |
For example: 75 ft × $400–$900/ft = $30,000–$67,500. Check your wall length and what the price includes.
What to include in your price
Ask for a written list of what the price covers. Include the related work below when planning your total budget.
- Survey, professional assessment, design and any ground investigation.
- Old-wall removal, disposal, temporary protection and land or barge access.
- Wall system, cap, anchors, returns, drainage, backfill and any required riprap.
- Dock/lift changes, utility disconnections and reinstatement.
- Local, state and federal approvals; inspections and final survey.
- Pavers, irrigation, planting, fences and other site restoration.
- Written exclusions, unpriced scope, change orders and an owner-chosen reserve.
Permit fees are a separate budget line
Your budget: Use a written project quote, then identify exclusions, allowances and unpriced work. The calculator gives a starting range from published Southwest Florida prices, or uses your own quote. These examples are not a Naples market average.
The City’s December 2023 seawall checklist lists a $100 permit fee, a review fee of 20% of that amount, $25 zoning and $35 for each initial required inspection. These are dated published components, not a verified current total. Obtain a fresh fee assessment before budgeting.
Collier’s fee index identifies a schedule effective January 1, 2026. Ask the county to identify the marine line items for your declared work value and scope.

Price access before selecting a low bid
Ask the contractor to identify the delivery route, equipment footprint and staging location. On City projects, the published checklist limits staging locations and excludes residential vacant lots.
- Does the price include barge or land mobilization?
- Who disconnects and reinstates dock utilities?
- Are pavers, irrigation, planting and fences restored?
- Is access permission needed from another owner?
Make two quotes comparable before adding a reserve
Quote A: wall work only
The price includes the wall but excludes engineering, permits, dock changes and yard restoration. Put those exclusions on separate lines and request prices. An excluded item with no price is still an open cost.
Quote B: broader scope
The price includes some of those items, but uses allowances for access and restoration. Ask what each allowance covers and how an overrun would be authorized. Check that both quotes use the same wall length and work limits.
This is a scope example, not a sample Naples price. In the planner, enter the quote you actually received and add only costs outside it. Do not add an included permit allowance twice. A reserve applies to known costs; it does not price omitted work.
Keep uncertainty visible
Use “unpriced” when an item is unresolved. A contingency is a separate owner-chosen allowance; it should not hide missing engineering, riprap or access work.
Ask for the quote’s validity date, payment milestones and written change-order process. Reconcile both bids to the same scope before comparing their totals.
