Boat dock repairs cost between $889 and $5,663, with a national average of $3,201. Your total repair cost depends on the size of your dock, the complexity of the repairs, and the materials used. The condition of your pilings and foundation will also impact the cost. Since boat docks are heavily exposed to the elements, it's important to schedule routine maintenance and address necessary repairs promptly.
Boat Dock Repair Cost Factors
The cost to repair a boat dock primarily depends on two main factors: materials and labor. The type of dock you choose, the climate, and the day-to-day maintenance and wear-and-tear a dock receives also determine how much and how often you'll pay for dock repair.
Materials
The dock’s materials directly impact repair costs; some base materials are less costly, more readily available, and easier to work with, which helps to keep costs down.
| Material | Cost Range per Square Foot | Average Cost per Square Foot |
|---|---|---|
| Pine | $3–$12 | $7.50 |
| Cedar | $4–$15 | $9.50 |
| Pressure-treated wood | $5–$20 | $12.50 |
| Wood composite | $10–$50 | $30 |
| Hardwood | $8–$35 | $21.50 |
| Vinyl | $4–$15 | $9.50 |
| Aluminum | $5–$20 | $12.50 |
| Plastic | $3–$12 | $7.50 |
| Concrete | $25–$250 | $140 |
Labor
The price of labor is fairly consistent per hour, regardless of the problem or material requiring attention.
Hiring a specialist to repair a dock costs $50 to $100 per hour. Your chosen professional may charge by the hour or project for both repairs and installation, so make sure to get quotes from multiple companies.
Most dock repair services have a minimum project fee, so even if you only need a few deck boards repaired, you'll pay for at least a couple of hours of labor. Urgent repairs also carry a higher fee or an emergency call charge, increasing the project's overall cost.
Location
Dock location influences the repair cost; every body of water poses different levels of challenge, accessibility, and complexity. For example, a small, still pond is much easier to work on than a fast-flowing river.
Docks on ponds are the least costly to repair, ranging from $200 to $1,350, while rivers are the most expensive, with typical costs of $275 to $1,650. A river’s relatively less favorable and more challenging working conditions drive up the costs.
| Location | Price Range | Average Price |
|---|---|---|
| Pond | $200–$1,350 | $775 |
| Lake | $250–$1,500 | $875 |
| River | $275–$1,650 | $960 |
Inspection
Having a professional dock inspection every year and after major storms can save you money long term. A dock inspection costs $50 to $100. The pro undertakes a visual inspection of the dock, including pilings, frames, boat lifts, the foundation, and more. They look for established problems or signs of developing issues and provide you with a full report. This lets you take care of highlighted issues before they become more serious and more costly to fix.
Maintenance
Regular maintenance costs far less than extensive repair. Perform routine cleaning, make sure to suitably treat metalwork to prevent rust, keep an eye out for rusty nails or cracked boards and treat wood with oils or sealant every year to prevent rotting.
Boat Dock Repair Cost by Dock Type
The type of boat dock you have affects the repair cost, as the parts, materials, and complexity of the repairs vary considerably. Simple algae buildup on a crib dock in a still pond, for example, costs significantly less to repair than replacing cables on a suspension dock located in a fast-flowing river.
Consider the typical cost ranges and average costs for dock repairs by dock type for an average 400-square-foot dock.
| Dock Type | Cost Range | Average Cost |
|---|---|---|
| Crib | $225–$1,650 | $940 |
| Piling | $250–$1,500 | $875 |
| Pipe | $250–$1,500 | $875 |
| Roll-in | $250–$1,500 | $875 |
| Lift-up | $250–$1,800 | $950 |
| Floating | $250–$1,800 | $1,025 |
| Suspension | $275–$1,800 | $1,040 |
Boat Dock Repair and Replacement Parts Costs
Even simple docks are reasonably complex structures, with many separate parts that may need repair or replacement individually or together at any given time.
Repair Costs by Part
Below are the typical costs for repairing different parts of a boat dock:
| Repair Part | Cost Range | Average Cost |
|---|---|---|
| Bumper | $85–$125 | $105 |
| Floats | $100–$150 | $125 |
| Frame | $150–$500 | $325 |
| Roof | $150–$1,000 | $575 |
| Boat lift | $175–$500 | $340 |
| Piling | $200–$700 each | $450 each |
| Post | $200–$700 each | $450 each |
| Board | $4–$35 per sq. ft. | $19.50 per sq. ft. |
| Decking | $4–$300 per sq. ft. | $152 per sq. ft. |
Replacement Costs by Part
Replacement usually costs more than repair. However, replacing an old part extends the dock’s lifespan and should reduce structural maintenance and repair.
| Replacement Part | Cost Range | Average Cost |
|---|---|---|
| Boards | $4–$35 per sq. ft. | $19.50 per sq. ft. |
| Decking | $4–$300 per sq. ft. | $152 per sq. ft. |
| Bumper | $8–$30 per sq. ft. | $19 per sq. ft. |
| Boat lift cable | $25–$50 per linear foot | $37.50 per linear foot |
| Float | $150–$200 each | $175 each |
| Pilings | $300–$1,600 each | $950 each |
| Posts | $300–$1,600 each | $950 each |
Boat Dock Repair Cost by Problem
Getting rid of algae buildup or replacing corroded nails, for example, typically costs only $100 to $250, and you'll pay less than that if you can do the job yourself. However, if the dock foundation needs repair, you'll need to hire a local dock repair pro and can expect to pay up to $3,000.
| Problem | Cost Range | Average Cost |
|---|---|---|
| Algae buildup | $100–$250 | $175 |
| Rusty nails | $150–$250 | $200 |
| Cracking | $150–$600 | $375 |
| Splintering | $150–$750 | $450 |
| Sinking | $150–$800 | $475 |
| Rust | $150–$1,000 | $575 |
| Rot | $200–$2,000 | $1,100 |
| Hurricane damage | $250–$2,000 | $1,125 |
| Damaged foundation | $750–$3,000 | $1,875 |
Boat Dock Repair Cost by Service
There are several common problems and associated repair services common to docks. Consider some of the most common repair services and their average cost for a standard 400-square-foot dock.
| Service | Cost Range | Average Cost |
|---|---|---|
| Pressure washing | $100–$200 | $150 |
| Dock sealing | $150–$600 | $375 |
| Dock leveling | $200–$900 | $550 |
| Reinforcement | $250–$1,500 | $875 |
| Restoration | $500–$2,000 | $1,250 |
Boat Dock Repair vs. Replacement
Replacing a boat dock costs $7,250 to $26,000, including removal fees of $250 to $1,000. However, the cost of building a new dock comes in at $4,060 to $25,970, depending on the size and materials. While this is a significant sum, it's less expensive than the cost of building a seawall or bulkhead, priced at $10,000 to $100,000.
Docks have a limited lifespan. A traditional wooden boat dock lasts between 10 and 20 years, even with regular maintenance. After this time, they degrade quickly as rot and other structural issues develop. If your dock is old or you're frequently making repairs, these costs can quickly add up and exceed the cost of installing a new dock.
Before deciding whether to repair or replace your dock, consider the nature of the problem, how much you've spent on recent repairs, potential upcoming repairs, and your dock’s age.
DIY vs. Hiring a Dock Repair Pro
Some dock repair tasks you can do yourself to save money. Pressure washing, sealing, and replacing rusted nails require minimal skills and equipment. If you have the time and tools, handling these tasks can save you a few hundred dollars.
However, for more extensive repairs, attempting to fix the problem yourself can worsen the issue and lead to higher repair costs than if you'd hired a professional in the first place. Additionally, improper repairs can be dangerous and lead to serious injury. Hire a local dock repair professional to ensure your boat dock is safe and functional.

Frequently Asked Questions
Boat docks need maintenance every year. Scheduling a comprehensive inspection at the end of each warm weather season prevents minor issues from turning into major repairs. Annual upkeep—including cleaning, repairing defective parts, and applying protective treatments—preserves the dock’s structure. Consistent maintenance ensures safety and prolongs the dock’s durability while minimizing repair costs over time.
In most cases, yes, pressure washing a boat dock is a great idea. Pressure washing costs $210 to $450, removing algae buildup, stains, and debris, helping to keep your dock in excellent condition. However, some materials, such as vinyl and certain composites, may not be suitable for pressure washing. Always check the manufacturer's recommendations before proceeding.
On average, a boat dock lasts between 10 and 20 years. Performing regular maintenance and reapplying protective treatments as needed will help extend the life of your dock. It's important to address issues promptly to prevent them from becoming more significant problems.
