Hull Cleaning in San Diego, Done by Hand

Q: How often do I need a bottom cleaning?

We highly recommend getting the bottom of your boat cleaned every 3 weeks between the months of April and October. The reason is that marine growth increases substantially due to warm waters. At this time, we usually see the growth of green and brown algae, and also sea animals like white coral worms.

Q: What happens if I don't clean my hull regularly?

Not only can failure to have your hull cleaned every 3 weeks result in cosmetic issues, it also affects your fuel consumption. Failure to keep on top of bottom care can result in galvanic corrosion in the metals and structural issues.

Q: Will hull cleaning damage my bottom paint?

We clean by hand with soft pads, which removes growth while preserving the bottom paint. Keeping the bottom clean is one of the best ways to make the paint last.

Q: Do you come to my dock?

Yes. We serve yacht clubs, shipyards, marinas, moorings, private residences and docks across Shelter Island, Harbor Island, Point Loma, Coronado and Mission Bay (Quivira Basin, Dana Landing, Marina Village, Hyatt and Bahia).

Your bottom paint, your fuel bill and your thru-hulls all depend on what is growing under your boat. Justin Time Diving has been cleaning hulls in Southern California since 2015.

Why Justin Time Diving

Divers who treat your hull like their own

We clean by hand, with soft pads, so the bottom paint stays on the boat and the growth comes off. Every thru-hull and intake gets checked, not just the flat of the hull. We are fully licensed and insured, and we work on vessels of all sizes, all kinds of bottom paint and all modes of propulsion.

What’s included

Every hull cleaning covers

Hand cleaning with soft pads
Algae, slime and barnacles removed without scraping away the paint you paid for. Power washing is available upon request.
Thru-hulls and intakes
We go through every thru-hull and intake, so water keeps flowing to your engines and systems.
Underwater inspection
While we are down there, we look at the hull and the metals and tell you what we find.
Zinc replacement as needed
Anodes are replaced when they are worn — not before.
Underwater videos upon request
See the condition of your hull without leaving the dock.

How often

Every 3 weeks from April to October

Warm water speeds up marine growth. Between April and October we see green and brown algae and white coral worms settle fast, so we recommend a cleaning every 3 weeks in that season. Outside it, we build a schedule every 4 weeks.

Justin Time Diving has helped keep the bottoms of our 10 racing sailboats in great condition. Not only does Gustavo come clean right before a race but also helps with post race inspections. The attention to detail is unmatched to other services!
Paul Crownover
These guys are great! I’ve been using them for the last couple of years on our rental fleet and they do a stellar job! Reliable, punctual, and professional. 10/10 would definitely recommend.
Mark
Justin is very conscientious and detail orientated. We dry sail our 52 foot boat San Diego and are able to continually inspect his work out of the water. It always looks good as new. Thanks very much!
Rene' Roques
Wow, great service! Personable, on time, fairly priced, knowledgeable and has a can-do attitude. Looking forward to using them again
Kayla McDaniel
Gus was our diver for a few months prior to selling our late father's sailboat. He was the most reliable diver we've worked with this year. His services were fairly priced, he was very communicative and reliable. He was always quick to get back to me whenever I reached out to him. He shared photos with us after the initial cleaning. Really pleasant experience working with Gus. I'd recommend Justin Time Diving to anyone looking for a reliable diver who does good work and a good rate.

We have been using Justin for 2 years now. We are so impressed with his work and customer service! Not only does he clean our hul and replace our zincs, he details our boat once a year and it is flawless! Great work, and great prices! We highly highly recommend him! Thanks Justin!!!

Ed Badrak
Justin has service my boat for well over four years. The integrity and ethics that he demonstrated while taking care of my boat is beyond reproach. He kept me informed about the condition of the bottom of my boat. He always advised me on the season's planned maintenance schedule. I highly recommend this individual to anyone looking for a person who will care and love their boat as you do. A true professional

Justin unlike a number of boat divers knows how to take care of your boat. He doesn't try and have you replace items such as zinc before it's time. He is willing and able to do multiple things on your boat or will give you the name of the right person. Knowing Justin for a number of years and having work on my boat I would highly recommend him.
Marc B
So I've known Justin for several years now, and he's taking excellent care of my boat! He's a very experienced diver and knows exactly what he's doing and how to take great care of boats. I highly recommend his services. And one of his most important attributes is he's conscientious and takes care of what needs to be done with no nonsense. You can definitely count on him and the work that he does is always perfect.

I'm the owner of a 42' Eggharbor Sport Fishing Yacht. Justin has been servicing my boat the past 3 years now since we had the bottom painted. Recently found out the bottom has an extra 2-3 years before repainting again. Typically I am repainting every 5 years because of how much use we have, or maybe that our last diver was doing the wrong job, possibly no job... He has saved me a BOAT load of money by the quality work that he is doing. Also best price for metals. Highly recommend!
Rich Zbinden
