Marina Maintenance Guide: 10 Essential Tasks

Maintaining a marina is crucial for ensuring safety, functionality, and longevity. Without regular upkeep, marina structures, equipment, and utilities can deteriorate quickly, leading to costly repairs and potentially dangerous situations. Whether running a small dock or a large marina, following regular marina maintenance will ensure smooth operation and enjoyment.

At Haven Dock & Marine, we understand the unique challenges marina owners face. In this comprehensive guide, we’ll discuss ten essential marina maintenance tasks that will help keep your facility in pristine condition.

1. Weekly Visual Inspections

One of the most critical aspects of marina maintenance is conducting regular, preferably weekly, visual inspections. These inspections are a form of preventive maintenance. They will allow you to spot minor problems before they become significant issues, especially ones that could quickly become a priority as a safety matter.

Regular dock inspections are essential for ensuring safety and longevity. The key components to focus on during an inspection are dock structure (especially after storms), electrical equipment, and safety features. By inspecting your dock regularly, you can identify potential issues that could compromise the structure of your boat dock or marina.

Your Visual Inspection Checklist

More specifically, inspectors should check for:

• Loose boards
• Rotting cross beams
• Nails and screws flush with surfaces
• Planking laid close together and properly spaced
• Securely hinged and fastened dock sections
• Cleats and pilings in good condition
• All electrical supplies and wiring are up to date, tidy, and in safe working order
• All hardware and dock accessories: nuts, bolts, dock ladders, stairs, cables, winches
• Etching, discoloration, weakness 
• Splintering wood
• Rust on steel parts
• Cracked concrete surfaces
• Fire safety and first aid kits are updated and accessible
• Dock accessories are in good condition and free from tripping hazards

Haven Dock & Marine offers easy-to-install, rugged hardware and accessories that withstand heavy use and harsh marine conditions, including Lake Lite Solar Powered Lighted Cleats that light up at night and floating dock hardware of all kinds.

2. Deep Cleaning: Annually and Seasonally

Deep cleaning your marina reduces wear and tear on surfaces like wood, metal, and plastic, making it inviting for visitors. For best results, aim to deep clean at the start and end of each season.

Create a Care Plan Based on Dock Materials

Pressure-treated and Hardwood Docks

While wood is a cost-effective choice, not all wood measures up the same way; marine-grade, pressure-treated lumber is hardier and will hold up better in the long run. Regular sealing will be required to keep it looking nice and functioning well.

Ipe, or Brazilian Walnut, is also an excellent choice for a dock and will require regular oiling and cleaning.

To keep your wooden docks in tip-top shape, try power washing them every few months with fresh water mixed with mild soap. Then, follow up by scrubbing away any remaining dirt or debris using a brush before letting them dry completely overnight. Stand and stain it afterward to preserve and protect the wood—staining seals the wood, preventing water and UV damage.

Aluminum Docks

Aluminum docks are highly durable and lightweight. Watch out for corrosion with aluminum docks, especially in saltwater environments, and clean regularly to avoid oxidation. 

Composite Docks

Composite decking is low-maintenance but should still be cleaned and inspected for signs of wear. These highly durable materials can be pressure washed without damaging the surface. While they typically require fewer maintenance tasks than traditional wood decking, you still need to give them a little love.

Polyethylene Docks

These docks require the least maintenance but should still be checked for damage, especially around joints and floatation areas.

3. Monthly Electrical System Checks

Marina electrical systems are prone to corrosion due to exposure to water, salt, and weather elements. Conduct more thorough monthly checks of your electrical system to ensure the safety and functionality of electrical panels.

Wiring and Outlets

Look for any exposed or damaged wiring, and repair immediately.

Power Centers

Test for proper operation and voltage output. It’s also a good idea to conduct an infrared imaging test annually to spot any electrical system issues that are invisible to the naked eye.

4. Foundation and Structural Inspections

The foundation of your marina is its backbone. A compromised foundation can spell disaster for the entire structure. At least once a year, thoroughly inspect the dock's foundation, especially the posts that anchor docks in place:

• Wooden foundations are prone to underwater rot.
• Posts should be anchored at least four feet into the seabed or lakebed to ensure stability.
• In floating docks, ensure the floats are intact and functioning.

If you notice sagging or uneven floating docks, it could indicate that the floats need repair or replacement. Haven Dock & Marine offers industry-leading CWI® dock floats, high-quality AccuDock® floating docks, and a full line of floating dock accessories and hardware to keep your docks level and safe.

5. Dock Hardware Maintenance

Your dock hardware, including cleats, couplings, and dock fenders and bumpers, undergoes a lot of wear and tear. Regularly check for loose or rusted components and replace them as necessary. Rusted cleats or couplers can pose safety risks and reduce the dock's structural integrity.

Ensure all cleats are tightly fastened and do not show signs of corrosion, and secure connections for gangways, lifts, and handrails to avoid accidents.

6. Trash and Waste Management

Overflowing trash bins are not just unsightly; they attract pests and wildlife that can damage your marina. Regularly empty trash bins, especially during peak season, to prevent litter buildup and keep the environment clean. 

During off-hours, cover garbage with these trash receptacles from Haven Dock & Marine to prevent animals from rummaging. It's also helpful to keep things tidy in order to eliminate trip hazards.

7. Safety Equipment Checks

Marina safety equipment should be inspected weekly and thoroughly tested at least monthly to keep you, your crew, and visitors safe.

Fire Extinguishers

Ensure they are fully charged and within easy reach.

Lifebuoys and Flotation Devices

These should be visible and well-maintained, ideally placed every 200 feet along the dock, as per the United States Coast Guard’s recommendations.

Access Ladders

Regularly check for rust, loose bolts, or any signs of instability.

Tidiness of Marina Equipment

Tangled cords, improper use of marine equipment, and places where someone could slip should also be addressed. Dock boxes and storage solutions are a great way to keep your area tidy and avoid trip hazards.

To keep your marina prepared for emergencies, check out Haven Dock & Marine’s selection of dock safety equipment, including life rings, dock ladders, Firehouse fire extinguishers, dock storage containers, and a full array of lighting options for strong visibility day or night.

8. Pest Control

Pests like birds, rats, and insects can damage both docks and boats. Bird droppings can ruin surfaces, while rodents can chew through the electrical components and wiring.

Install bird deterrents such as spikes or netting, and set up rodent traps or repellents to prevent them from nesting in dock structures.

9. Signage and Rule Enforcement

Ensure all safety, directional, and informational signage around your marina is visible and in good condition. Faded or broken signs should be replaced immediately to prevent confusion or accidents.

Ensure all guests, especially the littlest adventurers and those with fur, have clear expectations about what is allowed and not allowed with dock safety rules.

10. Recognize When It's Time to Replace or Repair Your Dock

While minor repairs can temporarily help maintain a dock's appearance and functionality, many docks, especially wooden ones, will eventually need to be completely replaced.

Rot, Rust, and Splintering

If you notice widespread rot across several wood boards, it's likely time to replace the entire dock. Excessive rot or rust, especially when fixing a few boards isn’t enough, is a clear sign that your dock has reached the end of its lifespan. Regular maintenance can extend the life of your dock, but neglect accelerates the need for replacement.

Foundation Issues

Severe foundation damage is another indicator that a total replacement is necessary. Wood foundations submerged in water tend to rot more quickly due to constant exposure to moisture and aquatic life. Dock posts should be anchored at least four feet into the ground. If your dock doesn’t meet this standard, the structure and its foundation will likely need to be replaced.
