What does a useful price need to describe?
A wall length is only the starting point. A useful estimate names the material, retained height, site conditions, removal work and access. Ask whether riprap, drainage, cap work and restoration are included.
The calculator offers national planning ranges and a place to enter your own quote. Neither a national range nor wall length alone establishes the Lake Martin price. Keep unpriced items visible.
Which local fee is published?
Alabama Power’s July 2025 residential guidelines list a $400 general construction fee for applicable new shoreline work. Ask the office which fee category fits your repair or mixed scope. Add local review, survey and design separately where applicable.
StillWaters has its own repair and project categories. A no-cost association repair permit is not a waiver of Alabama Power charges or other approvals.

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 this check is based on
The questions cover signs shown in the City of Holmes Beach seawall manual (pages 5–13): soil loss, wall movement, open joints and damaged concrete. These are general condition examples, not Lake Martin permitting or design standards.
Plan your seawall budget.
Three questions give you a national starting range for supported work. “Not sure” is welcome. No contact details needed.

What could your seawall cost?
National price ranges help you start a budget. They are not Lake Martin quotes; your wall’s height, condition and access can change the total.
Choose the work, length and material in the calculator for a published starting range. You can also enter your own quote, add known extras and set a reserve.
Repair prices by type
For a rough repair budget, multiply the affected length by the national range below. A site assessment must establish the repair method; major structural damage can exceed this range.
| Work | Amount | What the price covers | Area and source |
|---|---|---|---|
Seawall repair | $100–$250 | per foot of wall; General repair work; extent and method must be assessed. Price only the length being repaired. | U.S. national guidance — not Lake Martin quotes Angi |
New-wall prices per foot
These national installation ranges come from Angi’s October 12, 2026 guide. Replacement may also require old-wall removal. Ask what each quote includes before comparing prices.
| Material / work | Price per foot of wall | Area, included work and source |
|---|---|---|
Vinyl wall | $200–$600 | U.S. national guidance — not Lake Martin quotes · Published installation range. Confirm design, removal, access, drainage and cleanup separately. Angi |
Steel wall | $250–$700 | U.S. national guidance — not Lake Martin quotes · Published installation range. Confirm design, removal, access, drainage and cleanup separately. Angi |
Concrete wall | $200–$800 | U.S. national guidance — not Lake Martin quotes · Published installation range. Confirm design, removal, access, drainage and cleanup separately. Angi |
Wood wall | $150–$500 | U.S. national guidance — not Lake Martin quotes · Published installation range. Confirm design, removal, access, drainage and cleanup separately. Angi |
Riprap shoreline | $70–$400 | U.S. national guidance — not Lake Martin quotes · Published installation range. Confirm design, removal, access, drainage and cleanup separately. Angi |
50-, 75- and 100-foot examples
Multiply the wall length by the price per foot. The arithmetic below uses the published national ranges. It does not adjust for height, access, removal or other site costs.
| Material / work | 50 feet | 75 feet | 100 feet |
|---|---|---|---|
Vinyl wall | $10,000–$30,000 | $15,000–$45,000 | $20,000–$60,000 |
Steel wall | $12,500–$35,000 | $18,750–$52,500 | $25,000–$70,000 |
Concrete wall | $10,000–$40,000 | $15,000–$60,000 | $20,000–$80,000 |
Wood wall | $7,500–$25,000 | $11,250–$37,500 | $15,000–$50,000 |
Riprap shoreline | $3,500–$20,000 | $5,250–$30,000 | $7,000–$40,000 |
For example: 75 ft × $200–$600/ft = $15,000–$45,000. 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.
- Inspection, design, wall material, wall length and planned height.
- Removing the old wall, waste disposal, site access and temporary protection.
- Drainage, soil behind the wall, supports, wall cap, docks and utilities.
- Permit applications, fees, inspections, cleanup and final paperwork.
- Extra costs, work left out, a reserve for unexpected work and approval of price changes.
Why can similar walls produce different quotes?
- A narrow driveway can change equipment choice.
- A barge needs suitable water access and staging permission.
- Demolition and disposal may be separate line items.
- Unexpected weak ground can change the design.
- Steps, docks, irrigation and landscaping add restoration work.
How should you handle changes?
Define which quantities are fixed and which are allowances. Require written scope and price approval before a change. Agree on the evidence for hidden conditions, such as dated photographs and measured quantities.
Compare payment milestones with actual deliverables: permits, materials, completed stages and closeout. Verify the contracting entity and qualifications before signing.

How to use these prices
We reviewed Angi’s national construction and repair guides on November 4, 2026. The calculator multiplies the relevant per-foot range by your entered length. It keeps repair and installation rates separate and applies no guessed local discount or complexity multiplier. Your own quote can replace the published range. Alabama Power fees are listed separately in the permit guide; a permit fee is not the full approval cost.
