Contact Sergio’s Boat Spa. Most trusted boat repair, fiberglass & detailing in Stockton, CA
If your boat has a gouged hull, a chalky and faded gelcoat, a crack you keep meaning to deal with, or it just needs a real detail before the season, you’re in the right place. Sergio’s Boat Spa is a fully insured boat repair shop in Stockton, California, serving boat owners across the entire California Delta. We do three things, and we do them under one roof: fiberglass repair, gelcoat restoration and color match painting, and full boat detailing. Reaching us takes about thirty seconds, and you’ll have a firm quote in hand the same day. Most boat owners who call us are a little tired of how marine repair usually goes. You drop your boat off and never hear back. Weeks pass, your calls go unanswered, and half the season slips by. Or worse, the repair gets done but you can still see the patch, the color doesn’t match, and now it shows on the hull and at resale. We built this shop to be the opposite of that experience. When you contact Sergio’s Boat Spa, you get a real person, a clear timeline, and a number that doesn’t change. That’s the whole point.
The fastest way to reach us: text a photo
The single easiest way to get a boat repair quote in Stockton or anywhere in the Delta is to text us a photo. Snap a quick picture of the damage, the gouge, the crack, the oxidation, the dull spot, and send it to the number below along with the marina or city you’re slipped in. We’ll send back a free, same day quote with a firm price and a realistic timeline. No pushy sales calls, no per-foot formula, no surprises. The number Sergio gives you is the number you pay.
We know why this matters to you. You don’t want to haul your boat out, drive it across town, and sit through a hard sell just to find out what a fiberglass repair or a detail is going to cost. A photo and a text get you 90% of the way there. If we need to see it in person, we’ll come to your slip for a free dockside estimate, more on that below.
Call, text, or email, whatever’s easiest

What happens after you contact us?
A lot of the anxiety around marine repair comes from not knowing what happens next. Here’s exactly how it goes when you reach out to Sergio’s Boat Spa, step by step, so there are no surprises:
• You text or email a photo of the damage, plus your marina or city and slip number if you have one.
• We reply the same day with a free quote, a firm price and a realistic timeline for your fiberglass repair, gelcoat restoration, color-match painting, or detail.
• If it needs an in person look, we schedule a free dockside estimate at your marina, usually within two to five days.
• Once you’re booked, you get a clear start date and finish date before any work begins. No vague “we’ll see.”
• We keep you updated while the work happens, you’ll always know where your boat is and when it’s ready.
• At the end we text you before and after photos, walk through care instructions, and stand behind the work. That’s it. No disappearing act, no missed season, no mystery bill at the end. The boat repair process should feel like handing your boat to a pro who treats it like their own, because that’s exactly what you’re doing.

What we can help you with
When you contact us, it helps to know what you need, but if you’re not sure, just describe the problem and we’ll point you the right way. Sergio’s Boat Spa handles:
• Fiberglass repair in Stockton & the Delta, spider cracks, gouges, impact dings, rub-rail damage, through-hull and waterline damage, soft spots, delamination, transom and stringer repair, both cosmetic and structural.
• Gelcoat restoration heavy, oxidation, chalking, and color fade brought back to the original shine, often without paint.
• Color-match painting, custom-tinted gelcoat and marine paint matched to your hull’s exact color so the repair disappears, on your boat and at resale.
• Boat detailing in Stockton, hand wash, oxidation removal, multi-stage polish, wax and sealant, and full interior detailing that brings your boat back to showroom-ready.

Why boat owners reach out to Sergio’s Boat Spa
There are plenty of places to get boat repair near Stockton. Here’s why Delta owners pick up the phone and text us instead, and what you can expect the moment you make contact:
• The repair disappears. We tint gelcoat or paint to your exact hull color so the fix, and the original damage, vanish. Most owners can’t find the spot without us pointing to it. That protects how your boat looks at the dock and what it’s worth at resale.
• We actually answer. From the first text to the final walk-through, you’ll always know your timeline and your number. The industry’s biggest failure is silence; here it’s the thing we’re known for.
• Back before the season. We give you a firm date before we start and work to it. Most fiberglass repairs run one to four days; gelcoat restoration one to two days; a full detail is a single visit.
• One shop, both jobs. Most detailers only detail and most repair shops only repair. We do both, so when a wash uncovers a crack, we fix it on the same visit, no second shop, no second guess about who’s touching your boat.
• Fully insured, since 2017. General liability plus care, custody, and control of your vessel, with a certificate we’ll email to your marina or carrier on request. We’ve serviced 2,000+ boats.
• Honest, per-boat pricing. We quote your whole boat on what it actually needs, not a perfoot formula that charges a clean boat the same as a neglected one. The number Sergio gives you is the number you pay
Frequently asked questions before you contact us
How fast will I get a boat repair quote?
Same day, in most cases. Text a photo of the damage to (209) 221-3781 in the morning and you’ll typically have a firm quote by the afternoon. It’s the quickest way to find out what fiberglass repair, gelcoat restoration, painting, or detailing will cost on your boat.
Do you come to my marina?
Yes. We offer free dockside estimates and mobile boat repair across Stockton, the Delta Loop, and the broader California Delta. Give us a slip number and gate access and we can usually be there within two to five days.
Can you actually make the repair invisible?
On gelcoat color-match repairs, that’s the entire point of the service. We mix tint to your specific hull color, then apply, sand, and polish so the repair blends in. On heavy structural fiberglass repairs we’ll show you the spot, but most owners can’t find it without us pointing.
How long will my boat be in the shop?
You’ll get a firm timeline before we start. Full details are one visit (about four to eight hours), gelcoat restoration is one to two days depending on hull length, and fiberglass repairs run one to four days depending on the damage and cure times.
Are you insured?
Fully insured for both general liability and care, custody, and control of your vessel. We can email a certificate to your marina or insurance carrier any time you ask.
Will I get a surprise bill?
No. We quote per boat, in writing, before any work starts. There’s no per-foot padding and no “we’ll see.” The number Sergio gives you is the number you pay.
Ready to see your boat look new again?
Stop putting it off, that gouge or that chalky hull won’t fix itself, and a small crack today can become an expensive structural job by next season.
Text a photo of your boat to (209) 221- 3781, email us at sergiosboatspa2@gmail.com, or fill out the 30 second quote form, and we’ll send back a free, firm, same-day estimate. Service across Stockton and the California Delta, fully insured, color-match guaranteed. Let’s make yours the best looking boat at the marina again, and this time, you’ll actually hear back
