Colorado's dedicated boat fiberglass repair specialists. Expert team, proven results. 4-6 week turnaround.
Your boat took a hit. Maybe it was a dock collision, a trailer accident, or grounding damage. Whatever the damage - from a hairline crack to a shattered transom - Fiberglass Worx handles every type of boat fiberglass repair to a standard that's better than factory. We're not a marina side project or a body shop that "also does boats." This is all we do, and our team brings over 20 years of combined fiberglass experience to every job in our dedicated indoor facility.
Boat fiberglass is engineered differently from automotive paint or RV sidewalls. Your hull is built with laminated fiberglass layers, resin saturation, and marine-grade gelcoat that works in salt water, fresh water, and Colorado's intense UV. When that hull gets damaged - whether from a dock impact, a trailer sideswipe, or years of high-altitude sun beating down on it - the wrong repair approach can make things worse. Body filler might hide a crack, but moisture still gets in. The resin deteriorates. The laminate delaminates. Six months later, the damage is worse than before.
Common reasons boat owners need fiberglass repair in Colorado:
Every service below is performed by the same experienced team, in the same climate-controlled indoor facility, held to the same better-than-factory finish standard. Whether your damage is cosmetic or structural, we treat your boat like it's our own.

When your boat has been in a collision, the fiberglass damage usually goes deeper than what's visible - cracks through the laminate, crushed core, shifted framing, and structural compromise. Fiberglass Worx performs full structural rebuilds on collision-damaged boats using marine-grade fiberglass, proprietary bonding compounds, and the kind of craft-driven precision that won't let a patch job leave the shop.

A stress crack around the transom, an impact crack in the hull, a spider crack in the gel coat - these might seem minor, but Colorado's freeze-thaw cycle and intense UV can turn a small crack into a big problem fast. We assess whether each crack is cosmetic or structural before touching it, then repair accordingly with a boat crack repair approach that determines root cause and applies the right fix.

Your boat's surface is gel coat - the protective, glossy layer that takes the beating. Cracks, chips, spider cracks, and crazing in that layer hurt appearance and can let moisture reach the fiberglass underneath. Fiberglass Worx performs gel coat crack repair with a proprietary color-matching process perfected by our expert team, so the repair disappears into the surrounding surface.

Years of Colorado sun, water exposure, and hard use can leave your boat's fiberglass looking dull, chalky, and tired - even when the structure underneath is sound. Our boat fiberglass restoration goes beyond a basic buff-and-wax, using a proprietary oxidation removal formula developed through years of hands-on R&D to restore your gel coat to a factory-fresh finish.
Learn MoreNo matter which specific service your boat needs - structural, cosmetic, collision, crack, or restoration - every job follows the same proven workflow in our dedicated indoor facility.
Bring your boat to our shop at 7685 Dahlia Street in Commerce City. We'll inspect it with you, assess the damage in person, and give you an honest assessment on the spot. No appointment required for estimates.
Once you give the go-ahead, we photograph everything and create a detailed repair plan. We document the damage to establish whether it's cosmetic or structural, then map out the exact repair approach and timeline.
The damaged area is ground down, sanded, and cleaned to reach solid, sound fiberglass. This is where shortcuts kill quality — if you don’t prep properly, nothing that follows will hold. We take our time here.
Using our proprietary bonding compounds and marine-grade fiberglass materials, the damage is rebuilt from the inside out. Structural work gets fiberglass mat and resin lamination with marine-grade saturation. Cosmetic work gets precise gel coat application. All of it happens in our climate-controlled facility where temperature and humidity are right for proper resin curing.
The repaired area is sanded, buffed, and color-matched to blend seamlessly with the surrounding surface. We perform a multi-point quality inspection before anything leaves the shop. Then we walk you through the finished work so you can see the result for yourself.

Everything you need to know about boat fiberglass repair at Fiberglass Worx.
Boat fiberglass repair typically ranges from around $1,000 to several thousand dollars depending on the type and extent of damage. Cosmetic repairs cost less than structural rebuilds. We provide free verbal estimates in person - no phone quotes, because every boat is different and your vessel deserves a proper assessment.
Most repairs are completed within 4-6 weeks from the time we start. That includes surface prep, repair, curing, finishing, and quality inspection. Compare that to the 4-8 month wait times that are common at marine dealers. The exact timeline depends on the severity and scope of the damage.
Cosmetic damage affects only the surface gel coat - scratches, chips, spider cracks, and minor scuffs where the fiberglass laminate underneath is still solid. Structural damage goes deeper - cracks through the laminate, holes, flex in the hull, or compromised framing behind the surface. The repair approach is completely different for each. We assess every job before starting and explain what we find.
Yes - this is actually common for us. Many auto body shops and even marine dealers won't take on complex boat fiberglass work because the construction is different from automotive bodywork and the techniques are specialized. We've rebuilt transom damage, repaired massive impact craters, and restored boats that sat in storage for years because nobody else would touch them. When other companies say no, we say yes.
Because boat fiberglass damage has to be seen in person to be properly assessed. A photo can show you a crack, but it can't tell you how deep it goes, whether the core has been compromised, or whether water has infiltrated the laminate. We give free verbal estimates at our shop so we can give you an honest, accurate answer - not a guess.
Absolutely. Colorado's high-altitude UV is significantly more intense than at sea level, which degrades gel coat faster and causes oxidation, chalking, and fading. The freeze-thaw cycle creates another problem - moisture gets into small cracks during warm days, then freezes and expands overnight, widening the damage. Storage and trailers also expose boats to impacts and weather stress that accelerate deterioration.
In most cases, professional fiberglass repair is significantly more cost-effective than full hull section replacement - and when done correctly, the repaired area is actually stronger than the original factory lamination. Replacement sections also come with their own challenges: availability, fit, color matching, and the labor to install them. We'll give you an honest recommendation during your free estimate. If repair isn't the right call, we'll tell you.
We work on virtually every fiberglass boat - Tige, Centurion, Mastercraft, Malibu, MasterCraft, fishing boats, day cruisers, sailboats, jet skis, and more. Whether it's a $15K jet ski or a $300K cabin cruiser, the repair standard is the same - better than factory. The same six-step process and marine-grade materials our team has perfected apply across all types.
No matter what kind of fiberglass damage your boat has - collision damage, crack repairs, gel coat restoration, or something nobody else will touch - it starts with the same step. Bring your boat to our shop in Commerce City for a free verbal estimate. We'll look at it, tell you exactly what's going on, and lay out your options. No pressure, no phone quotes, no runaround.
