When it comes to building a dock, understanding the costs involved is crucial. The price of your dock largely hinges on its size and the materials you choose. On average, you can expect to pay between $20 and $50 per square foot, with $40 being the typical rate. So, if you’re looking at a standard 400-square-foot dock, your total cost might range from $8,000 to $20,000. This range can vary based on features like lighting, storage, or any special design elements you want to incorporate. Knowing these figures will help you plan your budget and make informed decisions as you embark on your dock construction project.
Dock Cost per Foot
The cost of building a dock depends on the number of square feet needed, with average prices ranging from $20 to $50 per square foot and around $40 per sq. ft. on average. These estimates typically cover both materials and labor. Generally, a longer dock requires more material and labor, which increases the overall cost. If the dock extends into deeper water, additional expenses may also be incurred. Two primary types of docks—piling and floating—are typically priced by square foot. Dock installation costs can vary widely, from $2,000 to $22,600, based on factors like size, water depth, and type.
Square Footage | Average Cost (Labor Included) |
120 sq. ft. | $2,000 – $5,500 |
150 sq. ft. | $2,300 – $6,500 |
180 sq. ft. | $3,000 – $7,500 |
210 sq. ft. | $3,350 – $8,800 |
240 sq. ft. | $3,900 – $9,900 |
300 sq. ft. | $5,500 – $14,000 |
360 sq. ft. | $5,800 – $15,400 |
420 sq. ft. | $6,800 – $17,800 |
480 sq. ft. | $7,500 – $20,000 |
540 sq. ft. | $9,000 – $22,600 |
Dock Cost by Type
There are various types of docks available, each suited to different needs and environments. Some docks remain in the water year-round, while others are designed to be installed seasonally and removed as needed. Certain designs combine both stationary and temporary sections, allowing for flexible dock expansion. The type you choose will depend on your intended use, the installation area, and the desired aesthetics. Depending on the type, costs generally range from $25 to $120 per square foot, including installation.
Dock Type | Average Cost per Square Foot (Labor Included) |
Floating | $25 – $50 |
Piling | $30 – $60 |
Pipe | $30 – $65 |
Wheel-In / Roll-In | $40 – $70 |
Crib | $40 – $60 |
Lift-Up | $40 – $60 |
Modular | $50 – $70 |
Suspension | $60 – $120 |
Cost of a Floating Dock
Floating docks typically range from $25 to $50 per square foot, including installation. Costs vary based on the materials used, with aluminum docks being more affordable than concrete options. Floating docks are temporary structures that can be used independently or attached to other types of docks.
Cost of a Piling Dock
Installing a piling dock costs between $30 and $60 per square foot. Often associated with traditional docks, piling docks, also known as stationary docks, feature wooden decking attached to wooden pilings driven deep into the waterbed for stability. This permanent dock option remains in place year-round.
Cost of a Pipe Dock
Pipe docks cost around $30 to $65 per square foot, similar to piling docks. Although visually similar, pipe docks use PVC pipes filled with concrete instead of wooden pilings. This construction method makes them weighted and easy to install, earning them the nickname “PVC docks.”
Cost of a Wheel-In Dock
Wheel-in docks cost between $40 and $70 per square foot, installed. These docks are built with aluminum and use stainless steel screws to secure the legs, allowing for easy height adjustment from the top without entering the water. Suitable for various water depths, wheel-in docks are convenient for fluctuating water levels and can be used in shallow to deep water areas.
Dock Cost Factors
The cost of your dock primarily depends on the total square footage. On average, costs range from $20 to $50 per square foot, with most installations averaging around $40 per square foot.
Dock Size and Cost
The cost of a dock largely depends on its size, with average costs ranging between $20 and $50 per square foot. However, using premium materials like exotic hardwoods or concrete can increase the price significantly, often doubling the standard cost.
Dock Cost by Square Footage
Square Footage | Average Cost Range |
120 sq. ft. | $3,360 – $8,400 |
150 sq. ft. | $4,200 – $10,500 |
180 sq. ft. | $5,040 – $12,600 |
210 sq. ft. | $5,880 – $14,700 |
240 sq. ft. | $6,720 – $16,800 |
300 sq. ft. | $8,400 – $21,000 |
360 sq. ft. | $10,080 – $25,200 |
420 sq. ft. | $11,760 – $29,400 |
480 sq. ft. | $13,440 – $33,600 |
540 sq. ft. | $15,120 – $37,800 |
Cost of Dock Decking by Material
The overall cost of a dock installation is significantly influenced by the decking material you choose. Decking prices range from affordable wood options to high-end, highly durable materials like concrete. On average, decking costs around $50 per square foot. When selecting decking, consider both its longevity and the aesthetic you wish to achieve.
Below are common decking materials with associated costs per square foot, including labor, with options ranging from $15 to $600.
Material | Cost per Sq. Ft. (Labor Included) |
Pine | $15 – $50 |
Plastic | $25 – $80 |
Cedar | $30 – $80 |
Vinyl | $30 – $80 |
Pressure Treated | $30 – $90 |
Aluminum | $35 – $95 |
Hardwood | $40 – $100 |
Concrete | $220 – $600 |

Cost of Dock Replacement
Replacing a dock involves both installation and removal costs, depending on the removal requirements and the extent of frame or substructure replacement. Decking replacement alone typically costs between $40 and $300 per square foot, depending on the dock’s size. In some cases, only the damaged or rotted decking may need replacement.
Additional replacement costs depend on specific dock components. Replacing floats on a floating dock costs between $250 and $300. Frame repairs range from $250 to $600, and new bumpers can add $10 to $40 per square foot. Replacing pilings and pipes can be more expensive, costing $400 to $1,900 per piece.
For complete removal and replacement with a different dock style, expect to pay a removal cost of $350 to $1,200, plus the cost of the new dock type, which averages around $17,000.
Dock Configuration Options
While the most common dock setup involves a main section extending straight over the water, there are many other configurations available. For instance, a narrow walkway can broaden into a larger dock area and then narrow again at a boat slip.
For those with multiple boats, it may be useful to consider dock configurations such as F, I, L, T, U, E, or H shapes, allowing for boat slips to be attached in various positions. Some designs feature a patio area at one end or a Harbor-style layout, where a walkway runs parallel to the water with arms extending outward. Selecting the best configuration depends on how you plan to use the dock—whether for fishing, sunbathing, or entertaining, which may require a wider area, or simply for single-boat access, which can utilize a narrow walkway.
Cost of F Shape Docks
F-shaped docks feature two parallel extensions branching off the main section, creating a unique design. This configuration is particularly useful for docking small personal watercraft, as it allows for easy access from either side. It’s an excellent choice for households with two watercraft, with one positioned on each side of the parallel extensions.
Cost of L Shape Docks
L-shaped docks are ideal for fishing, swimming, and sunbathing, featuring an upside-down L design with one vertical section and a horizontal decking piece. The decking runs parallel to the shoreline, providing ample space for chairs and lounging while enjoying scenic water views.
Cost of U Shape Docks
U-shaped docks are perfect for homeowners with various types of boats. This design allows for secure storage of up to three boats while also providing space for swimming. The center of the U is best suited for smaller vessels, such as fishing boats, kayaks, and canoes, while the outer sections accommodate recreational boats and offer convenient access to the water for swimming.
