Boat repair in Stockton, California
Sergio's Boat Spa is the boat repair shop Stockton boat owners call when they want the job done right and want to actually hear back. Our shop sits at 745 South Lincoln Street, right at the gateway to the California Delta, and we have serviced more than 2,000 boats here since 2017. We do everything under one roof, fiberglass repair, gelcoat repair, color match painting, and full boat detailing, so you are never bounced between a detailer and a separate repair shop.
Everything your boat needs in one Stockton shop
Most repair shops only repair and most detailers only detail. We do both, which means when a wash uncovers a crack or a chalked hull needs a color matched patch, it is handled in one place, by one team, on one visit. That is how we keep Stockton boats on the water instead of stuck in a queue.
Fiberglass repair
Cracks, gouges, impact damage, and structural work on the keel, transom, stringers, gunwales, and rub rails. We rebuild with new fiberglass and resin to restore strength and the original shape.
Gelcoat repair and color match
Oxidation removal, restoration of chalky and faded hulls, and exact color matching so the repair disappears completely, on your boat today and at resale tomorrow.
Boat detailing
Hand wash, oxidation removal, multi stage polish, wax and sealant, and a complete interior detail that brings the boat back to showroom ready.
Every service, one shop
“Everything under one roof” is the whole menu, not just three things. At Sergio's Boat Spa that means fiberglass repair, gelcoat repair and restoration, color match painting, oxidation removal, buffing and polishing, ceramic coating, interior detailing, wash and wax, bottom painting, blister and osmosis repair, and full boat restorations, handled by one team, on one quote, in the right order. That sequencing matters: structure before finish, correction before protection, detail last. Doing it all in one place is why a wash that uncovers a crack gets fixed on the same visit, instead of bouncing you between a glass shop, a bottom yard, and a detailer who each blame the last one.
What actually happens to your boat in the shop
A lot of owners have never seen how a proper glass and gelcoat repair is actually done, which is exactly why a cheap patch is so easy to sell. Here is the real sequence. First we grind the damage back to sound material, because a good repair is always a little bigger than the crack you can see, the goal is to remove every compromised layer, not just hide the surface. Then we rebuild the laminate with new fiberglass cloth and resin, layer by layer, until the original strength and shape are back. We fair the area dead flush so there is no high spot or low spot to catch the light. Only then does the finish go on: tinted gelcoat or color-matched paint, sprayed and blended, then wet sanded and buffed until it reads as one continuous surface. Skip any one of those steps and the repair telegraphs, a patch you can feel with your hand or pick out in raking sun. Doing all of them, in order, is the difference between a real fix and a cover up that comes back next season.
Why color match is the part most shops get wrong
Matching color on a boat is harder than matching a car, and it is where a lot of repairs quietly fail. Your hull is not the color it was the day it left the factory, years of Central Valley sun have shifted it, so the new finish has to match the boat as it sits today, not the chip in the owner's manual. On metalflake and pearl finishes it is harder still: the flake has to land at the same density and angle, or the patch flashes a different shade every time the boat turns in the light. We match to the weathered hull, tint by eye and by sample, and feather the new finish into the surrounding panel instead of stopping at a hard tape line. That is why our work holds up from three feet away and from across the slip, not just on the bench under shop lights. When a repair is done this way, the only person who knows it is there is you.

Why Stockton boat owners choose Sergio's
We are the local shop that answers. Fully insured for general liability and the care, custody, and control of your vessel. Every boat quoted on what it actually needs, never by the foot, so the number Sergio gives you is the number you pay, with no padding and no surprises. From the first text to the final reveal, you always know where your boat is and when it will be ready.
Why owners switch to the shop that answers
Ask any boat owner about a bad repair experience and you'll hear the same thing: they dropped the boat off and never heard back. Weeks of silence, unreturned calls, a boat that vanished into a queue. The single biggest complaint about marine shops isn't the work, it's the disappearing act. We built Sergio's Boat Spa around the opposite. You get a firm date before we start, updates through the job rather than weeks of nothing, and before and after photos at the end. You always know where your boat is, what it'll cost, and when it's coming back. For most owners who switch to us, that reliability is the real reason.
What actually drives the price
Because we price each boat on what it actually needs instead of a flat rate, it helps to know what moves the number. Cosmetic gelcoat work sits at the affordable end; structural repair to a transom, stringer, or keel costs more because there is real rebuilding happening underneath the finish. Color complexity matters too, a solid white hull is quicker to match than a multi stage metalflake or a faded custom color that has to be tinted from scratch. The size and number of damage spots, whether the boat has to come out of the water, and how much surrounding area needs to be blended all factor in as well. When we quote your boat we walk you through which of these apply, so the price makes sense instead of feeling like a mystery, and so you can decide together what to handle now and what can safely wait.
Signs your boat needs a pro
Catch these early and the fix is small; ignore them and they compound. Watch for: hairline or spider cracks in the gelcoat; a chalky, faded hull that won't shine up with a wash; soft or spongy spots in the deck or floor; rust streaks and a waterline scum line; a gouge or crack below the rubrail; and growth or staining on the bottom of a slip kept boat. If you're seeing any of them, text a photo, we'll tell you straight whether it's urgent, what it is, and what it'll take, at no cost.
What the Delta does to your boat
Boats in Stockton take a specific kind of beating, and knowing the causes helps you stay ahead of them. The Central Valley sun is brutal on gelcoat months of unfiltered UV chalk and fade a hull faster here than in cooler, cloudier places, which is why oxidation is the single most common thing we treat. Wind across the open sloughs pushes boats into docks and pilings, so rash along the rubrail and gunwale is routine. Trailer and ramp work adds its own scuffs and stress cracks. And boats that sit in the water all season pick up staining at the waterline and, eventually, blistering below it. None of this means you did anything wrong it is simply what Delta boating costs a finish over time. The good news is that caught early, almost all of it is still cosmetic, which means cheaper, faster, and far less likely to turn into structural work down the road.
Boats we work on
We repair and refinish every kind of boat on the Delta, and each type has its own quirks we know cold: wake and ski boats with premium metalflake finishes that are easy to mismatch; bass boats with high gloss flake; fishing boats that need structural transom and stringer work; pontoons that are mostly detailing plus a fiberglass console; jet skis and PWC; and big cabin cruisers that need glass, bottom, and interior work together. Whatever you run, the standards are the same, color match that disappears, per boat pricing, and real communication.

Are you insured?
Fully insured for general liability and care, custody, and control of your vessel. We can send a certificate to your marina on request.
What types of boats do you work on?
All of them, wake, ski, bass, and fishing boats, pontoons, jet skis and PWC, cabin cruisers, and more. Each type has its own quirks and we handle all of them. See the individual boat type pages for specifics.
Do you handle insurance claim repairs?
Yes. We provide detailed, itemized estimates that work with most marine carriers (Geico Marine, Progressive, BoatUS and others) and can send before/after documentation straight to your adjuster.
Do you do bottom paint and blister repair?
Yes, for slip kept boats we handle antifouling bottom paint and blister/osmosis repair below the waterline, in addition to the above the waterline work. See those service pages for details.
What's the difference between a repair and a restoration?
A repair fixes a specific problem; a restoration combines several services (structure, finish, protection, detail) in the right order to bring a tired boat all the way back. We'll tell you honestly which your boat needs.
How long do repairs take?
Most fiberglass repairs are 1–4 days, a full detail is a single visit, and restorations vary with scope. You always get a firm timeline before we start.
Can you match a faded or discontinued color?
Usually, yes. We match to your hull as it looks today, not the original factory chip, and tint gelcoat or paint by sample until it lands. Faded, custom, and discontinued colors are exactly what real color-matching is for.
Do you stand behind your repairs?
Yes. We do the repair the right way, back to sound material, rebuilt and blended, so it lasts. If something isn't right, we make it right. We would rather do it once than have you back for the same spot.
Can you work on my boat in the slip, or does it have to come out?
Bottom paint and blister work below the waterline need the boat hauled. We'll tell you exactly which yours needs when we quote it.
How do I keep a fresh repair looking new?
A regular wash plus a wax or ceramic coat keeps the sun from re chalking the finish, and a cover helps if the boat sits. We'll recommend the right level of protection for how you store and use your boat
