Instead of wrestling your vessel onto a trailer, you can call us and have a trained technician show up at your slip, storage yard, or private dock ready to work.

Gel Coat Scratch, Gouge & Fiberglass Patch Repair
Dock rash, oyster bar scrapes, and trailer rollers all leave their mark on your hull's gel coat. We apply a fiberglass patch where needed, grind out the damaged layer, build it back up with color-matched gel coat compound, and finish to a smooth, UV-resistant surface. Catching these early prevents water intrusion into the underlying laminate.

We regularly work in Jensen Beach, Palm City, and Hobe Sound, and we travel south to Tequesta and Jupiter as well as north to Fort Pierce and Port St. Lucie.

Wherever your boat lives — slip, storage yard, or backyard — our team brings the repair to you.

Common Signs You Need Fiberglass Repairs
Spotting fiberglass damage early means a simpler, less expensive fix — and having a proper repair kit on hand for minor issues is smart, but most boat owners in South Florida's year-round boating season benefit most from professional fiberglass repairs using the right mat, cloth, and resin for the job. A hull problem discovered today can sideline you tomorrow if it's left alone.
Spider Cracks Appearing:
A cluster of fine cracks radiating from a single point usually means the hull has absorbed impact stress or is flexing more than it should. Left alone, these cracks allow water into the laminate. The best way to repair fiberglass in these cases is to grind back to solid material and re-laminate.
Soft or Spongy Deck:
When you feel give underfoot on a section that used to feel solid, the core material beneath the fiberglass skin is likely waterlogged or rotting. We cut away the compromised area, dry the substrate, and lay fresh fiberglass mat to restore structural integrity. This worsens quickly in warm, humid conditions.
Visible Blistering Below the Waterline:
Bubbles or raised patches on the hull bottom indicate osmotic blistering, where moisture has penetrated the gel coat and is reacting with the laminate. We use fiberglass cloth and epoxy barrier coat to seal and restore the hull after drying. Ignoring blisters leads to deeper structural damage.
Discoloration or Delamination:
Dark staining or areas where the outer skin sounds hollow when tapped point to delamination — the bond between fiberglass layers has failed and the section is no longer structurally intact. A professional boat repair assessment will determine the extent of the damage before any laminate work begins.
Frequently Asked Questions
How much does fiberglass repair typically cost?
Cost depends heavily on the size and depth of the damage. A small gel coat scratch might take under an hour, while a transom rebuild or large delaminated section is a multi-day job. We assess the damage on-site and provide a clear quote before any work begins — no surprises.
Can fiberglass repair be done at my dock without hauling the boat?
Yes, in most cases. Our mobile setup is designed for on-site work, and the majority of hull repairs — including gel coat work, stress crack repair, and blister treatment — can be completed right at your slip or storage yard. Extensive transom rebuilds occasionally require the boat to be on a trailer for better access, and we'll tell you upfront if that applies.
How long does a typical repair take?
Small cosmetic repairs are often finished the same day. Structural work like delamination repair or a transom rebuild may take two to three visits depending on cure times for epoxy and resin. We schedule around your calendar and give you realistic timelines from the start.
Will the repaired area match the rest of my hull?
We color-match gel coat to your hull's existing finish as closely as possible. Older hulls that have faded from sun exposure may show a slight difference until the new gel coat weathers to match, but we take care to blend the repair into the surrounding area. Pairing the repair with boat detailing afterward can help even out the overall appearance.
How do I know if my boat needs fiberglass repair or a full marine diagnostic services?
If you can see the damage — a crack, blister, or soft spot — fiberglass repair is likely the right starting point. If you suspect hidden structural issues or your boat is showing multiple symptoms at once, a full marine diagnostic is a smart first step so we understand the complete picture before we start cutting into anything.
