Boat Dock Prices by Type
The cost of your boat dock depends largely on the type you choose.
| Type of Dock | Cost |
|---|---|
| Floating | $15–$35 per square foot |
| Piling | $20–$40 per square foot |
| Pipe | $1,000–$10,000 total |
| Cribe | $10,000–$50,000 total |
| Suspended | Varies |
Floating Dock
Floating docks cost between $15 and $35 per square foot, including both materials and labor. The most affordable option is a prefabricated aluminum floating dock, which starts at $750. These docks are built by placing decking over airtight barrels, drums, or marine floats. Here are some of their benefits:
Least expensive
Small ones are easy to remove from the water
Easy to maintain
Less stable, especially in high-traffic water
Flotation may be damaged during low tides
Best for lakes or sheltered coves
Pilings Dock
Piling dock building and installation run $20 to $40 per square foot. Machinery drives or jet pilings, generally 10” to 12” in diameter, into the lakebed. A few benefits include:
More expensive than floating due to complex build and installation labor
Not compatible with some types of terrain
Permanent and durable if maintained properly
Customize it into boathouses, gazebos, and party decks
Pipe Docks
A prefabricated aluminum pipe dock will cost between $1,000 and $10,000 total. The top perks of pipe dock include:
Easy to assemble
Not permanently affixed for easy removal
Comes with wheels or stationary posts
Requires an even lakebed or seafloor for installation
Not suitable for mooring larger boats
Good for lakes with calm waters
Crib Docks
Crib docks cost $10,000 to $50,000 or more. They are constructed by filling one or more square wooden “cribs” with large rocks and then capped with a deck. They are essentially small, synthetic islands that can be connected to the shore with decking. Here are some things to consider with crib docks:
Requires a permit due to environmental concerns. Check with your pro or the local zoning or building permit office for specifics.
Higher installation cost
Good for choppy or cold northern waters
Not suitable for extremely deep water
Can last over 50 years
Suspension or Cantilevered Articulating Docks
Engineering challenges make these unique, uncommon, and expensive. Due to this, you’ll need to contact a local engineer near you to obtain a project quote. A suspension dock overhangs the water like a suspension bridge with only one side. Some of the benefits of a suspension dock include:
Low environmental impact and good for areas with a fragile underwater ecosystem
High aesthetic value
More costly to install than other dock types
Requires more time to plan and construct
Dock Cost Factors
Plan to spend $15 to $40 per square foot for most docks. Premium picks—such as exotic hardwood or concrete—can significantly increase that number.
Size
The size of the dock directly influences the material and labor costs. Larger docks cost more in both materials and installation time.
| Square Footage | Average Cost Range (Including Labor) |
|---|---|
| 120 | $1,800–$4,200 |
| 150 | $2,250–$5,300 |
| 180 | $2,700–$6,300 |
| 210 | $3,150–$7,400 |
| 240 | $3,600–$8,400 |
| 300 | $4,500–$10,500 |
| 360 | $5,400–$12,600 |
| 420 | $6,300–$14,700 |
| 480 | $7,200–$16,800 |
| 540 | $8,100–$18,900 |
Labor
Plan to allocate roughly half of your budget to cover labor costs. For example, a $10,000 dock includes $5,000 in labor, or $50 per linear foot.
The primary professionals involved in dock construction include dock builders, carpenters, marine contractors, and sometimes engineers. Their costs can vary based on expertise and regional market rates:
Dock builders and marine contractors oversee the overall construction and installation, ensuring the dock meets all necessary safety standards.
Carpenters charge $75 to $125 per hour. Responsible for building wooden components of the dock, like decking and framing.
Structural engineers are required for complex designs and charge $70 to $250 per hour. They design specialized docks, like suspension or cantilevered types.
Materials
Materials costs vary based on the size of your project. Cedar is the most economical material, starting at $4 per square foot, while concrete can reach up to $300 per linear foot.
| Material | Cost per Sq. Ft. |
|---|---|
| Cedar | Starting at $4 |
| Exotic Hardwoods (like Ipe, Camaru, and Tigerwood) | Up to $25 |
| Composite | $30–$40 |
| Aluminum | $30–$40 |
| Concrete | $150–$300 per lin. ft. |
Boat Dock Add-On Costs
Your final price tag depends on the type of dock you choose and its features. Adding a ram can cost over $1,000, while pilings start at $10 per foot.
| Dock Type | Cost |
|---|---|
| Piling | $10–$15 per ft. |
| Drums or floats | $75–$400 each |
| Ladder | $100–$600 each |
| Bumper | $50–$100 each |
| Ramp | $500–$1,000+ |
| Mooring whips | $300–$500 each |
| Decking | $4–$40 per sq. ft. |
| Boat lift | $1,000–$15,000 each |
| Boathouse | $10,000–$50,000+ |
Piling
Piling costs $10 to $15 per square foot. A dock piling is the upright posts driven into the lake or seabed. The frame either attaches to these for fixed decks or wraps around them for floating types, allowing travel up and down the piling during water level changes.
Drums or Floats
Drums or floats can cost from $75 to $400 each, depending on the size and material you choose. Airtight drums or floats keep a floating dock afloat, with decking placed over them.
Ladder
A dock ladder costs $100 to $600. If you plan to use your dock to get in and out of the water for swimming or other water activities, a ladder is a must-have dock improvement for added safety.
Bumper
Dock bumpers cost between $50 and $100 each, depending on their size. They protect both the dock and boats during docking by absorbing impact and preventing damage.
Ramp
Installing a dock ramp costs between $500 and $1,000. Ramps are designed for launching boats by backing them into the water using another vehicle. They’re beneficial if you plan on regularly moving watercraft in and out of the water.
Mooring Whips
Mooring whips cost $300 to $500 each. These whips resemble fishing poles, affixed at certain angles and tensioned to hook boats as they come in. They’re designed to protect the finish on boats in areas with rough wakes by holding them a safe distance away from the dock.
Considerations When Choosing a Dock
Building a dock requires thorough planning and decision-making. Consider factors such as dock type, materials, electrical requirements, and your budget before beginning construction.
To determine the best type and materials, boat owners should consider:
Regional-specific construction regulations
Climate and location: Is your boat on a frozen lake or hurricane-prone coastline?
Water depth and bed composition: Help determine the length of piles.
Saltwater or freshwater: Each requires different materials and treatments.
Seawall or Bulkhead Cost
Steel and concrete seawalls cost $150 to $600 per linear foot for a basic installation. Engineering, permitting, plumbing, and electrical needs will increase the price. Residential wood bulkheads tend to fall on the lower end of the spectrum.
Does Building a Boat Dock Increase Home Value?
A well-built dock can significantly increase your property value, often by 8% to 15%, according to real estate experts. Waterfront homes with private docks command premium prices, particularly in vacation destinations or areas where boating is a popular activity. The investment return varies based on your location, dock quality, and market conditions. Permanent structures made from high-quality materials tend to offer the best return on investment (ROI), while proper maintenance ensures your dock remains an asset rather than a liability. Before building, research comparable waterfront properties in your area to gauge the potential value increase and ensure your investment aligns with neighborhood standards.
DIY vs. Hiring a Professional Boat Dock Builder
A poorly built dock quickly becomes a safety and maintenance headache. Building a dock requires specialized knowledge, skills, and experience. It's a big project that’s best left to a professional who specializes in boat dock installation. To find a qualified professional, always get at least three quotes and read dock company reviews.

Frequently Asked Questions
EZ Dock modules range in price from a few hundred to a few thousand dollars, depending on size and additional features. These plastic- or aluminum-framed sections snap together quickly, giving you a lightweight, flexible system that’s easy to move or expand. Add-ons such as rails, ladders, or integrated lifts push the total toward the higher end of the range.
Dock repairs average $3,215, but your bill will vary depending on the scope of work. Fixing structural damage, swapping out rotted boards, or treating rust all add labor and materials. Location, dock design, and the products you choose drive the final price, and hidden issues uncovered during the job can nudge costs higher. Budget a little cushion so unexpected repairs don’t leave you scrambling.
Swapping a wood frame for aluminum, paired with composite decking, can increase your build by roughly 20% to 50%. Material choice is the quickest way to change the bottom line, but you can still mix and match—think aluminum posts with wood or plastic planks—to hit the look you want without breaking the budget. These combinations enhance durability while allowing you to tailor the final design.
You can tackle a simple floating dock on your own if you’re comfortable with tools and local codes. Anything that involves driving pilings, engineering a suspension system, or working in deep water is best left to a licensed pro who has the equipment and permits. DIY where it’s safe and straightforward; call a specialist when structural integrity or safety is at risk.
Most jurisdictions require a permit—and sometimes several—before you install a permanent dock. Ensure you check city, county, and HOA rules early and confirm whether state or environmental agencies also need to approve. Securing paperwork up front keeps the project legal, helps you avoid fines, and prevents delays once construction begins.
Local rules set the maximum length and layout. Many areas cap a dock at one-quarter of the waterway’s width to protect navigation, shoreline habitat, and public access. County, city, or HOA boards may also regulate width, decking materials, and rail height. Before you sketch a design, review those codes so your plans sail through permitting.
