How Much Does Boat Cleaning Coast? A Complete Breakdown for Boat Owners

Why Boat Cleaning Costs Vary So Much

In the same way that car washes offer different packages, boat cleaning isn’t “one-size-fits-all.” The price depends on the time, labor, tools, and level of effort required. Here are the biggest factors that affect what you'll pay:

1. Boat Size

Size is the single biggest cost factor. A 16-foot center console naturally takes much less time to clean than a 35-foot cabin cruiser or a sailboat with multiple deck levels.

As a rough rule:

• Smaller boats cost less simply because there’s less surface area
• Larger vessels require more labor, more materials, and often more than one technician

2. Type of Boat

Hull shape, deck layout, cabin size, and the amount of hardware all influence difficulty.

For example:

• Pontoon boats usually require more interior cleaning
• Sailboats have complex rigging, non-skid surfaces, and more detail work
• Sportfish boats and cruisers often have multiple levels and enclosed cabins
• Personal watercraft are the quickest and cheapest to clean

3. Type of Cleaning Requested

A basic washdown is a world away from a full interior scrub or hull cleaning below the waterline.

Here are the most common service categories:

• Exterior washdown
• Hull cleaning (above and/or below waterline)
• Interior cleaning
• Salt removal
• Non-skid scrubbing
• Mildew treatment
• Compartment, console, and storage cleaning

The more detailed the service, the higher the cost.

4. Condition of the Boat

A boat that’s washed regularly is far easier to clean than one that’s been sitting for months covered in dirt, salt, or algae.

Boats with:

• Mold or mildew
• Heavy waterline scum
• Stains built up over time
• Thick marine growth
• Heavy oxidation

…will almost always cost more.

5. Where the Boat Is Stored

Boats kept in the water typically need more frequent and more intensive cleaning. Boats on lifts or trailers accumulate less growth and are easier to access.

6. Your Location

Boat cleaning prices vary based on cost of living, local demand, seasonal availability, and regional water conditions. Coastal areas tend to have higher salt and mineral buildup, which means more frequent cleaning.

Average Cost of Common Boat Cleaning Services

While prices can vary, here are general price ranges most boat owners can expect.

▶ Exterior Boat Washdown

A washdown is the most common cleaning service and typically includes rinsing, soaping, scrubbing, and drying the boat’s exterior.

Average cost:

• $4–$12 per foot, depending on boat size and condition
• Smaller boats: $60–$150
• Medium boats: $100–$250
• Larger boats (30 ft+): $150–$450+

Some companies charge flat fees, while others use per-foot pricing.

▶ Interior Boat Cleaning

Interior cleaning varies widely depending on layout and condition.

Interior cleaning usually includes:

• Vacuuming
• Wiping down all surfaces
• Cleaning cabins, heads, and galleys
• Treating mildew and stains
• Cleaning upholstery and compartments

Average cost:

• $8–$20 per foot
• Small boats: $100–$200
• Cruisers & sailboats: $175–$500+

Deep cleaning or mold treatment can raise the cost significantly.

▶ Hull Cleaning (Above Waterline)

This is typically part of a washdown, but deep waterline stain removal may cost extra.

Average cost:

• $5–$15 per foot
• Heavily stained hulls can cost more

▶ Hull Cleaning (Below Waterline)

If your boat stays in the water, expect this to be a regular expense during the active season.

Underwater hull cleaning includes scraping off:

• Barnacles
• Algae
• Marine growth
• Slimy buildup

Average cost:

• $2–$5 per foot for divers, depending on growth levels
• $100–$300+ for most recreational vessels

Boats with thick growth may be charged by time instead.

▶ Non-Skid Deck Cleaning

Non-skid is notoriously stubborn and time-consuming.

Average cost:

• $50–$200+, depending on surface area

▶ Canvas, Vinyl, and Upholstery Cleaning

Removing mildew and stains can take significant effort.

Typical cost:

• $75–$300+ depending on condition

▶ Add-On Services

Many boat cleaning companies offer extras like:

• Window & isinglass cleaning
• Rust removal
• Metal polishing
• Odor treatment
• Compartment cleaning
• Salt-neutralizing treatments

Prices usually range from $25 to $150+ depending on the task.

How Often Should You Pay for Boat Cleaning?

The frequency of professional cleaning depends on your boating habits.

If your boat is in saltwater:

• Washdowns after every outing
• Full cleaning every 2–4 weeks
• Hull cleaning monthly or bi-monthly

Saltwater demands more frequent maintenance.

If your boat is in freshwater:

• Washdowns every 1–2 outings
• Full cleanings every 4–6 weeks

Freshwater boats require less growth removal but still need routine care.

If you store your boat on a trailer or lift:

You can stretch cleanings further, but avoiding long-term buildup is still crucial.

Is Professional Boat Cleaning Worth the Cost?

While some owners prefer to do cleaning themselves, hiring a professional delivers several benefits:

1. Better long-term protection

Professionals use the right cleaners and equipment, reducing the risk of damaging gelcoat, vinyl, windows, or non-skid surfaces.

2. Major time savings

Cleaning a boat properly often takes hours. For larger boats, it can take a full day.

3. Improved appearance and resale value

A well-maintained boat looks newer for longer and holds its value better when it comes time to sell.

4. Reduced long-term repair costs

Salt, mildew, and algae can lead to expensive restoration work if left untreated.

5. Convenience

Mobile marine cleaning services come directly to your marina, dock, slip, or storage location.

Final Thoughts: What You Should Expect to Pay

Most boat owners can expect to spend:

• $100–$300 for a basic cleaning
• $200–$600 for a full exterior + interior clean
• $100–$300+ for hull cleaning
• More for larger vessels or neglected boats

While costs vary, consistent cleaning is far cheaper than major repairs caused by long-term neglect. When you invest in routine boat cleaning, you’re not just keeping your vessel attractive—you’re protecting its performance, structure, and overall value.
