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 organize observations about soil loss, wall movement, open joints and damaged concrete. They do not diagnose a cause or approve a repair. Before shoreline work, review Alabama Power’s Smith Lake shoreline guidelines and have the property assessed.

What could your seawall cost?
These are national price ranges from HomeGuide, not Smith Lake quotes. Wall height, access by land or water and the work included can change your total.
Pick the work, the wall length and a material in the calculator to see a starting range. If you have a written price, enter it to add known extras and a reserve.
Repair prices by type
Multiply the length being repaired by the range. An assessment sets the repair method, and structural failures cost more than minor repairs.
| Work | Amount | What the price covers | Area and source |
|---|---|---|---|
Minor repairs (non-structural), national guide | $100–$250 | per foot of wall; Cap cracks, new caps and tiebacks, joint grouting, secondary anchors and soil stabilization. | United States (HomeGuide national guide, 2023) [1] |
Rebuilding severely damaged sections, national guide | $150–$600 | per foot of wall; Leaning walls, joint separation, toe failure and badly damaged sections. | United States (HomeGuide national guide, 2023) [1] |
Old wall removal, national guide | $50–$150 | per foot of wall; Removing the old wall before a replacement; the price depends on the material and location. | United States (HomeGuide national guide, 2023) [1] |
New-wall prices per foot
National installed prices per foot from HomeGuide’s seawall cost guide, dated April 2023 and checked November 5, 2026. Ask what each quote includes before comparing it with these ranges.
| Material / work | Price per foot of wall | Area, included work and source |
|---|---|---|
Vinyl wall, national guide | $200–$550 | United States (HomeGuide national guide, 2023) · Materials and installation. The same guide prices old-wall removal, engineering plans and permits separately. [1] |
Steel sheet-pile wall, national guide | $200–$600 | United States (HomeGuide national guide, 2023) · Materials and installation. The same guide prices old-wall removal, engineering plans and permits separately. [1] |
Concrete wall, national guide | $200–$600 | United States (HomeGuide national guide, 2023) · Materials and installation. The same guide prices old-wall removal, engineering plans and permits separately. [1] |
Concrete-filled vinyl (Truline), national guide | $500–$1,200 | United States (HomeGuide national guide, 2023) · Installed price for one proprietary system: steel-reinforced concrete inside vinyl sheet piling. Other hybrid designs are priced case by case. [1] |
Wood wall, national guide | $150–$500 | United States (HomeGuide national guide, 2023) · Materials and installation. The same guide prices old-wall removal, engineering plans and permits separately. HomeGuide notes wood suits freshwater walls with little wave action. [1] |
Riprap rock shoreline, national guide | $50–$200 | United States (HomeGuide national guide, 2023) · Installed price, including grading and a geotextile layer under the rock. It varies with slope, depth, rock size and access. [1] |
50-, 75- and 100-foot examples
Multiply the wall length by the price per foot. These examples use wall length to show construction costs. Add any work not included in the price per foot.
| Material / work | 50 feet | 75 feet | 100 feet |
|---|---|---|---|
Vinyl wall, national guide | $10,000–$27,500 | $15,000–$41,250 | $20,000–$55,000 |
Steel sheet-pile wall, national guide | $10,000–$30,000 | $15,000–$45,000 | $20,000–$60,000 |
Concrete wall, national guide | $10,000–$30,000 | $15,000–$45,000 | $20,000–$60,000 |
Concrete-filled vinyl (Truline), national guide | $25,000–$60,000 | $37,500–$90,000 | $50,000–$120,000 |
Wood wall, national guide | $7,500–$25,000 | $11,250–$37,500 | $15,000–$50,000 |
Riprap rock shoreline, national guide | $2,500–$10,000 | $3,750–$15,000 | $5,000–$20,000 |
For example: 75 ft × $200–$550/ft = $15,000–$41,250. 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.
Is there a reliable Smith Lake price per foot?
No public Smith Lake bid with a price per foot turned up in this research, so the ranges here are national figures from HomeGuide. They cover materials and installation for a typical residential wall and carry their source and date; they are not local averages.
Use them for a first budget, then ask for a written estimate after a site visit. Record its date, length, material, wall height, access method and exclusions. The calculator multiplies a national range by your length, or uses a price you enter; it does not invent a local rate or recommend an engineered design.
What should the written price include?
- Assessment, survey, design and any additional soil or underwater investigation.
- Demolition, hauling and lawful disposal of the old wall or debris.
- Approved rock, wall components, foundations, anchors, caps and end connections.
- Drainage, filter material and suitable backfill.
- Equipment transport, barge or land access, temporary protection and mobilization.
- Applications, approved changes, inspections and close-out.
- Dock, lift, utility and landscape work affected by the shoreline repair.
- Final grading, planting, driveway repairs and cleanup.
For each item, mark it included, a separate amount, not needed or still unpriced. A blank line is not a zero-dollar allowance. Use the same list for every proposal so a shorter price does not hide missing work.
Why can two similar lengths cost differently?
An excavator that can reach a stable work pad needs a different plan from equipment that must arrive by water. Steep approaches, narrow gates, trees, septic areas and overhead or buried services can limit access. A low-water visit can help reveal conditions, but it cannot guarantee the level available during construction.
Ask the contractor to describe the access route and restoration in writing. Separate one-time mobilization from length-based work. For stone, compare the quoted weight or volume and the specified material, rather than assuming all “loads” contain the same quantity.

Which permit numbers can you use for planning?
The residential schedule revised July 15, 2025 lists $400 for general construction, $200 for substantial repair and $100 for a qualifying permit modification. Alabama Power determines the applicable categories. These are approval fees, not construction prices.
ADEM updated its construction permit in April 2026 and announced new fees from October 15, 2026. Use the current official fee calculator if the project needs coverage. Do not insert an old statewide amount into the bid.

How do you compare repair and replacement?
Request two clearly bounded scopes when both options are viable. A repair proposal should identify what remains, how the cause is addressed and what could still require later work. A replacement proposal should explain demolition, approved alignment and all associated drainage and site restoration.
Do not compare a repair subtotal with a complete rebuild total. Keep unknown work visible and ask what would trigger a change order. Choose an optional reserve based on your own budget; no percentage can make an undefined scope complete.

How to use these prices
We read HomeGuide’s national seawall cost guide on November 5, 2026. The calculator multiplies the per-foot range for your material by the length you enter. It keeps repair and new-wall prices apart and adds no local discount or markup. A price you enter replaces the published range. Alabama Power permit fees are listed separately, and a permit fee is not the full approval cost.
