Fiberglass & Gelcoat Repair
in Pinellas County
From stress cracks and impact damage to osmotic blisters and full hull restoration — we repair fiberglass boats to look and perform like new.
Quality Fiberglass Work That Lasts
Fiberglass damage doesn’t fix itself — and a poor repair makes things worse. At JG Coastal Marine Services, we use professional-grade materials and proven techniques to restore your hull structurally and cosmetically. Our color-matching process produces results that’re nearly impossible to spot.
We handle everything from minor gelcoat scratches to major structural repairs, osmotic blister treatment, and full hull fairing. Whether your boat took a dock hit, has spider cracks from age, or shows blistering from water intrusion, we’ve got the solution.

Fiberglass & Gelcoat Services
Gelcoat Scratch & Chip Repair
Minor surface scratches and chips filled, sanded, and color-matched so your hull looks like the damage never happened.
Stress Crack Repair
Spider cracks and stress fractures properly opened, filled with marine-grade materials, and sealed to prevent water intrusion.
Impact & Collision Damage
Structural and cosmetic repair from dock strikes, groundings, and collisions. We rebuild fiberglass laminate to factory strength.
Osmotic Blister Treatment
Diagnosis, grinding, drying, and barrier coat application to address osmotic blistering at the root and prevent recurrence.
Gelcoat Restoration & Polishing
Oxidized or faded gelcoat wet-sanded and polished back to a deep, glossy shine. Dramatically improves appearance and resale value.
Color Matching
We custom-mix gelcoat to match your hull’s exact color, even on older boats where the original shade has faded.
Hull Fairing
Filling and fairing uneven hull surfaces for a smooth, clean finish — ideal before bottom paint or a full repaint.
Transom Repair
Soft or delaminated transom repair and replacement using epoxy-saturated marine plywood for a solid, lasting fix.
Deck Core Repair
Spongy or soft decks caused by water-damaged core material repaired with new foam or balsa core and glassed over.
Our Repair Process
Free Assessment
We inspect the damage and give you an honest written estimate before any work begins.
Prep & Grind
Damaged material is ground out, edges feathered, and the repair area prepped for a permanent bond.
Laminate & Fill
Structural fiberglass layers are rebuilt and gelcoat or filler applied, wet-sanded to a perfect surface.
Color Match & Polish
Gelcoat is custom-mixed, applied, and buffed to blend seamlessly with the surrounding hull.
