- We work on powerboats, sailboats, and yachts, so whether you have a 20-foot center console or a 45-foot cruiser, the same crew handles the hull.
- Structural repairs, osmotic blister treatment, and surface fairing are all done in one visit when conditions allow, reducing your downtime to a minimum.
- Every fiberglass job starts with a free quote so you know the scope and cost before we touch the boat.
- Gelcoat finishing is kept separate from structural fiberglass work — we fix the laminate properly first, then discuss cosmetic options, so nothing gets skipped or rushed.


Hull Crack and Impact Repair
Collisions with submerged objects, dock strikes, and trailer rash can leave cracks that range from surface-deep to structural. We grind out damaged material, rebuild the laminate with marine-grade fiberglass cloth and epoxy or polyester resin, and fair the surface smooth. Catching these repairs early prevents water intrusion that weakens the surrounding hull.

Common Signs You Need Service
Fiberglass problems rarely fix themselves — what starts as a hairline crack can become a waterlogged laminate if left alone through a Florida wet season, so the sooner you call, the simpler and less costly the repair.
Cracks or Spiderweb Lines:
Visible cracks on the hull, deck, or transom — especially patterns radiating from a point — signal stress or impact damage that may extend deeper than the surface.
Soft or Spongy Deck:
Areas that flex underfoot where they used to feel firm indicate a saturated or rotted core that needs immediate attention before the damage spreads.
Blistering on the Hull Bottom:
Bubbles or raised bumps below the waterline are osmotic blisters; left untreated they enlarge and weaken the surrounding laminate over time.
Water in the Bilge After Dry Storage:
Finding water that doesn't trace back to rain or condensation often points to a hull crack or failed through-hull fitting letting water seep in while the boat sits.

Frequently Asked Questions
How much does fiberglass boat repair cost in St. Petersburg?
Cost depends on the size and depth of the damage — a small hull crack costs significantly less than a full transom rebuild or widespread blister treatment. We provide a free on-site or photo-based quote before starting any work, so you'll have a clear number upfront with no surprises.
Can you repair fiberglass at my marina slip without hauling the boat out?
Yes, in most cases. Deck repairs, topsides cracks, and above-waterline hull damage can all be handled while the boat is in the water or on a lift. Work below the waterline typically requires the boat to be out of the water, but we coordinate with local marinas on haul-outs when needed.
How long does a fiberglass repair take?
A straightforward crack or impact repair often takes a few hours in a single visit. Larger jobs — core replacement, transom rebuilds, or blister treatment across a large hull section — may require multiple sessions to allow resin to cure properly. We'll give you a realistic timeline when we quote the job.
Is fiberglass repair the same as gelcoat repair?
No — they're related but distinct. Fiberglass repair addresses the structural laminate: the layers of cloth and resin that give the hull its strength. Gelcoat is the pigmented outer coating that provides color and gloss. We repair the laminate first to make sure the structure is sound, and cosmetic gelcoat restoration is handled separately. Mixing the two up can lead to a repair that looks good briefly but fails underneath.
Do you work on older boats with polyester resin hulls?
Absolutely. Most production boats built before the mid-2000s use polyester resin, and we work with both polyester and epoxy systems depending on what the repair calls for. We'll choose the right material for your hull's original construction to ensure a compatible, long-lasting fix.
