Small cracks and puncture holes seem minor until Colorado’s climate turns them into real problems. Fiberglass Worx assesses every crack before touching it — we determine whether damage is cosmetic or structural, then repair it right the first time.
When outdoor temperatures swing 40 degrees between day and night, moisture gets inside cracks, freezes overnight, and expands. That expansion pushes fiberglass apart further. Add Colorado’s 15–20% more intense UV radiation at high altitude, and small cracks become structural failures in months, not years.
Road debris punctures RV sidewalls constantly. Removed fixtures like antenna mounts, brackets, and exterior vents leave holes behind. Stress cracks develop around windows, doors, and corners from constant road vibration. Many RV owners ignore these, hoping they’ll seal themselves. They won’t. Moisture enters through every opening and rots the wood framing or foam underneath, causing interior damage that costs thousands to fix.
Fiberglass Worx takes a different approach. We don’t guess — we assess. Our first step is determining whether your crack is cosmetic damage (gelcoat only) or structural damage (through the fiberglass laminate). Cosmetic cracks get cleaned, ground, and repaired using our proprietary color-matching process. Structural cracks demand serious work — we expose the crack, grind away damaged material, apply fiberglass mat and resin to rebuild laminate strength, then finish and color match. We find the root cause of cracks, not just repair the symptom. Our dedicated indoor facility with controlled temperature, humidity, and lighting lets curing compounds set properly. That means repairs last.
For detailed information on cosmetic repairs, see RV cosmetic fiberglass repair. For structural damage assessments, visit RV structural fiberglass repair. Both are part of our full RV fiberglass repair service menu.
Every crack and hole repair follows our proven 5-step process in our dedicated indoor facility.
Call us at (303) 585-0515 to schedule a free in-person assessment. Bring your RV to our yard and we’ll evaluate the damage on-site. If you can’t make it to us, we’ll arrange to come to your RV whenever possible. No obligation, no paperwork required.
Proper prep determines repair quality. We clean the damaged area thoroughly, removing dirt, old sealant, and oxidation. We grind away damaged gelcoat or fiberglass, exposing solid material underneath. Grinding removes weak layers and creates a surface that accepts repair material properly.
For cosmetic cracks, we apply proprietary gelcoat filler, sand smooth, and color match using our advanced matching system. For structural cracks, we apply fiberglass mat and resin lamination, building the fiberglass back to original thickness and strength. Holes get filled with resin and reinforced with fiberglass, creating a solid base.
All repairs get shaped, sanded, and finished to factory appearance. Our color-matching process accounts for fiberglass fading and aging. The repair disappears. Your RV looks undamaged.
Every repair gets inspected before your RV leaves our facility. We verify structural integrity, check color match, and ensure finish quality. If something doesn’t meet our standards, we redo it. Tell us what you need and we will handle the rest.

Everything you need to know about RV crack and hole repair at Fiberglass Worx.
Costs depend on damage size, type, and whether it’s cosmetic or structural. Cosmetic cracks run $150–$400. Structural repairs typically $400–$1,200. Puncture holes $200–$600 depending on location and size. We provide free estimates so you know exact cost before we start work.
We deliver 4–6 week turnaround on most repairs. That’s dramatically faster than the dealership standard of 4–8 months. Timeline depends on repair scope, our current workload, and cure time for materials. We give you a specific timeline when we provide your estimate.
Cosmetic cracks only affect the gelcoat surface layer — they’re visible but don’t compromise fiberglass strength. Structural cracks run through the fiberglass laminate and require serious repair with mat and resin lamination. We assess which type you have and repair accordingly.
No. Small cracks trap moisture. In Colorado, freeze-thaw cycles force that moisture into the fiberglass, expanding it and growing the crack. Interior foam and wood framing rot. What starts as a small $50 repair becomes a $2,000 interior restoration. Address cracks early.
Colorado’s 40+ degree temperature swings mean moisture gets into cracks during warm days. Overnight freezing expands that moisture. That expansion pushes fiberglass apart and enlarges the crack. This cycle repeats constantly, accelerating damage. Sealed and reinforced fiberglass prevents this cycle.
That depends on your policy and the cause of damage. Hail damage is often covered. Road debris damage may be covered. Freeze-thaw damage typically isn’t. We’ll document your damage and provide detailed information for your insurance claim. Contact your insurer for specifics.
We use an advanced color-matching system that accounts for fiberglass fading and aging. We test matches in natural light. The goal is invisible repairs — no one should see the damage was ever there. Our proprietary gelcoat compounds match factory finishes.
