What We Do
Fiberglass & Gel Coat Repair

Gel Coat Restoration / Wet Sanding
Our multi-step sand, buff, wash and wax process removes oxidation and makes an older boat look showroom-new again.
Custom Paint & Aluminum Boat Repair
Restore to factory finish, or make it one of a kind. Our paint tech has over 20 years of experience.
Bottom Paint
Hard or ablative anti-fouling paint, plus blister repair and barrier coat.
Transoms, Floors & Stringers
Structural repairs for fiberglass and aluminum boats — done right, so you're back on the water safely.
RV & Trailer Repair

How It Works
Getting an estimate is easy:
Send photos or stop by
Use the Request a Quote form, email photos to estimates@calibreboat.com, or bring it in Mon–Fri 9–5. No appointment needed.
We evaluate it in person if needed
Some damage, like hairline stress cracks, can't be fully seen in photos, so we may re-evaluate once we see it.
You approve the estimate
Ballpark "guesstimates" from photos are always free. Formal estimates are free when we do the repair. If you need a comprehensive written estimate for insurance only, and don't plan to have us repair it, there's a charge for that estimate — it takes an hour or more to prepare.
We repair it and stand behind it
We warranty our repairs.
Why Calibre
In an industry full of overnight "experts," everyone has an alibi — except us.
Calibre began in Wheat Ridge in 1973, founded by two friends in a small industrial park along I-70. It moved to a newly built facility near 62nd & Beach in 2005, grew again under new ownership in 2016, and relocated to our current Commerce City facility in 2019.
For more than 50 years, Calibre has remained family-owned and family-operated. We are not a "shade tree" garage — our equipment, experience, and repair processes reflect the standards we've upheld for decades. That's why the majority of Colorado marine dealers and insurance companies trust us.
Our promise: Being the largest marine body shop in Colorado doesn't mean we take anything for granted. Our reputation has been earned one repair at a time since 1973. If something isn't done correctly, we will do everything within reason to make it right.
The Work We Do Every Week
Hull damage repair & gel coat match, full wet sand & oxidation removal, custom paint, and RV sidewall fiberglass repair.
Brands We Service & Repair
What We Don't Do
We don't do engine/mechanical repair, curved windshield replacement, or shrink wrap — but we've been here 50 years, and we'll gladly refer you to a trusted partner who does.

RVs, Travel Trailers, Fifth Wheels & More
Fiberglass & gel coat repair, custom paint and decal replacement for Class A motorhomes, 5th wheels and travel trailers in Commerce City, CO.
Most RVs are fiberglass — and that's our specialty
We repair Class A motorhomes, 5th wheels, travel trailers, slide-in campers, and enclosed motorcycle trailers.
We can often save you money by gel-coating the damaged area instead of replacing panels. Just like a boat, we can wet sand your trailer to remove oxidation and make it look new again. We also specialize in custom painting, decal replacement, and precisely matching your RV's paint or gel coat.
