Holes, wall flex, cracks, and panel rebuilds that other shops refuse.
RV walls are engineered differently than anything else on the road. Your motorhome or travel trailer has a sandwich construction: an outer fiberglass shell, foam core insulation, wood framing, and an inner wall. When one of these layers fails, the whole structure is at risk. Body filler, sealant tape, and temporary patches don’t work.
Most collision shops and general repair facilities treat RVs like cars. They can’t. They lack the marine-grade materials, the understanding of laminated wall systems, and the controlled environment needed for proper resin curing. By the time moisture gets behind a patch, rot spreads through the foam and framing. The damage grows. Other shops turn away the hard cases. We solve them.
Structural damage isn’t cosmetic. A cracked laminate wall isn’t just ugly — it’s an invitation for water damage, rot, and catastrophic failure. Ignoring it will cost you thousands more down the road.
Fiberglass Worx specializes in structural fiberglass repair — the work that most other shops refuse. We rebuild from the substrate out using marine-grade fiberglass mat, premium resin, and proprietary bonding compounds tested and refined over years. We work in a dedicated indoor facility with temperature and humidity controls. Our team brings over 20 years of combined fiberglass experience.

You bring your RV to our facility in Commerce City. We inspect the damage thoroughly — not just the visible part. We check for moisture, rot, foam degradation, and framing issues. Then we carefully remove the damaged section: fiberglass, foam, wood — whatever needs to go.
The foundation matters. We clean and prepare the remaining substrate. We check for hidden damage, treat any wood rot with appropriate sealant, and ensure the repair area is ready to accept new fiberglass. Rushing this step leads to weak repairs. We don’t rush.
We apply marine-grade fiberglass mat saturated with premium resin. We layer multiple times, building structural strength. We use our proprietary bonding compounds to ensure every layer bonds perfectly to the substrate and to each layer above it. We work in our climate-controlled facility so the resin cures properly. This creates a repair stronger than the original construction.
Once the structural repair is cured, we sand, finish, and prepare the surface. We check for voids, weak spots, and any areas that need additional work. Then we let you inspect it before we release your RV. Quality matters — we prove it with 200+ five-star reviews.

No. Delamination is the separation of fiberglass layers without visible damage or openings. Repairing delamination would require removing and rebuilding most of the wall or panel, which is expensive and often not practical. The root cause — usually moisture — would still be present. We focus on structural damage like holes, cracks, wall flex, and framing issues where we can provide a complete, lasting repair.
