Boat Repair at Ladd's Marina in Stockton
Ladd's Marina is a family owned Stockton marina on the San Joaquin River, with around 200 slips, a launch ramp, a ship store, and easy access to the Delta. A lot of owners keep their boats in the water here all season, which brings a different kind of wear than a trailer boat sees: constant water contact, a waterline scum line, dock rash from the slip, and gelcoat that bakes under the Delta sun month after month. Sergio's Boat Spa handles all of it, a short run up the road at our South Lincoln Street shop in Stockton. Because your boat already lives at Ladd's, we make this simple. Text a photo and a few details, slip number, make and model, what you're seeing, and you'll have a free same-day quote with a firm price and timeline. For many jobs we come to the slip; for heavier structural work we'll have you bring it to the shop. Either way, you're never left wondering what's happening or what it will cost.
What slip kept boats at Ladd's need most
Boats that stay in the water collect a predictable set of problems, and most of them happen below your eye line. The waterline picks up staining and a scum line. The bottom can develop blisters and osmosis over time as moisture works into the laminate. Above the waterline, gelcoat oxidizes and goes chalky, and fenders and pilings leave rub marks and the occasional crack. The interior takes on humidity, which means mildew and that musty cabin smell if it isn't kept after. Because we do both repair and detailing under one roof, a single visit can address the whole boat instead of bouncing it between a glass shop, a bottom yard, and a detailer. That matters more on a slip-kept boat, where the to-do list tends to be longer and the boat is harder to move.
Full repair, finish, and bottom services
Above the waterline we repair fiberglass and gelcoat, color matched so the fix vanishes; remove oxidation and buff the hull back to gloss; and apply wax or ceramic coating to protect it. Below the waterline we handle bottom painting and blister/osmosis repair, done the right way, with proper grinding, drying, and barrier coating, not a quick patch that fails in a season. Inside, our detailing clears mildew and staining and protects the vinyl and upholstery. On a boat that lives in a slip, color match is just as important as it is on a trailer boat, a mismatched repair shows every time you walk the dock. We tint to your exact hull color so the repair disappears, which protects both how the boat looks at Ladd's and what it's worth when you sell.
Service that fits a slip kept schedule
Text photos of the damage or the areas you want addressed, plus your slip number, to (209) 221- 3781 for a free same-day quote. For details, oxidation removal, gelcoat touch ups, and many repairs we offer dockside service right at Ladd's; heavier structural fiberglass and bottom work is done at our nearby Stockton shop, and we'll tell you up front which applies. Through the whole job you'll know where your boat is and when it's done, no silence, no surprises.
Honest, insured, and on your side
We're owner-operated and fully insured, including care, custody, and control while your boat is with us, with a certificate available for Ladd's on request. Pricing is per boat, never per foot, so the quote you get is the price you pay. We've cared for more than 2,000 Delta boats since 2017, and what slip owners tell us they value most is simple: we answer, we update, and we deliver when we say we will.
Per boat pricing for slip kept boats
Slip kept boats at Ladd's often need a few things at once a little glass work, some oxidation removal, maybe bottom attention, and pricing that by the foot punishes you for it. We quote per boat instead, on exactly what yours needs, so a tidy boat that wants a touch up isn't charged like a project. You get a firm number before we start, and that's the number you pay. Payment is simple: card, cash, or Zelle. Because we do repair and detailing together, bundling the work into one visit usually saves you money versus paying two shops to mobilize to the same slip twice.
What to expect from start to finish
Text photos and your slip number for a free same day quote. We give you a firm date, and keep you posted through the job, no boat disappearing for weeks with no word. You'll know where things stand at every step, and we finish with before and after photos so you can see exactly what was done before you ever walk the dock.

Frequently Asked Questions
Can you service my boat right in its slip at Ladd's?
For details, oxidation removal, gelcoat touch-ups and many repairs, yes, we offer dockside service. Heavy structural fiberglass or bottom work is usually done at our nearby Stockton shop, and we'll tell you which applies up front.
My boat stays in the water, can you handle bottom and blister issues?
Yes. We do bottom painting and blister/osmosis repair below the waterline, which is common on slipkept boats at Ladd's. We grind out and dry the hull properly before rebuilding so the repair lasts.
Can you do an osmosis repair quickly?
No reputable shop can rush it, the hull has to be ground out and dried before rebuilding, or the blisters come back. We give you an honest timeline instead of a same-day patch that fails.
Do you remove the waterline scum line and oxidation?
Yes, oxidation removal, compounding, and polishing bring back the gloss above the waterline, and detailing clears the staining slip-kept boats pick up.
How do I get a quote without pulling the boat?
Text photos of the areas you want addressed plus your slip number to (209) 221-3781 for a free same day quote.
Will the repair be visible?
No, we color match to your exact hull color so the repair blends in and disappears, at the dock and at resale.
Is my boat insured while you have it?
Yes, fully insured for care, custody, and control. A certificate can be emailed to Ladd's or your carrier on request.
Can you bundle several jobs into one visit?
Yes, and it usually saves money. Handling glass, finish, and detailing together means one mobilization to your slip instead of several.
How do I pay?
Card, cash, or Zelle. You're quoted a firm per boat number up front and that's what you pay
