Full Fiberglass Panel Replacement in Yorba Linda

Full panel replacement removes and replaces an entire fiberglass sidewall, cap or slide face when repair is no longer viable. Where the manufacturer no longer supplies the panel, we mould a replacement in house from the surviving side or a pattern.

Panel replacement is the end of the decision tree, and it is a decision that should be made with both numbers on the table rather than by default.

It becomes correct in three situations. The debonded area covers most of the panel. The substrate is rotted across a large area. Or the damage crosses moulded features that will not reproduce convincingly as a repair.

When does replacement beat repair?

The rule of thumb we use is that when the repair figure reaches about sixty percent of the replacement figure, replacement is the better outcome.

That is not purely about money. A large repair on a highly visible surface carries appearance risk that a replacement does not. A replaced panel is a new panel. A large repair is a large repair, and on a coach you may sell later that distinction has value.

The exception is a vehicle where panel availability is poor and moulding is required, which raises the replacement figure substantially and shifts the balance back toward repair.

What happens when the manufacturer no longer makes the panel?

We make it. That capability is the reason we can take on coaches from manufacturers that no longer exist.

A mould is taken from the opposite side of the vehicle where the geometry mirrors, or from a donor panel, or built to a pattern taken off the vehicle. The replacement is then laid up with a reinforcement schedule matched to the original, including any local reinforcement the original design included around openings and mounting points.

This is a substantial part of the labor on an older coach and it is why panel replacement on a discontinued model can approach the cost of a much larger repair on a current one.

How is a panel replacement actually performed?

The panel is released at its bonded perimeter and mechanical fasteners, taking care not to damage the framing it is bonded to. Everything mounted through it, meaning windows, lights, vents, awning rails and slide seals, comes off and is catalogued.

Framing is then inspected in full, because whatever destroyed the panel usually reached the frame behind it. Substrate is replaced. The new panel is bonded with the specified adhesive under controlled clamping pressure across the full area, which is why this work happens indoors at controlled temperature rather than outside.

Refinish then blends into the adjacent panels so the replacement does not read as a new section on an older vehicle.

Our Process and Timeline

Shop hours and calendar days are different things. These are the stages and the realistic duration of each.

  1. 01

    Assessment and decision

    Both repair and replacement figures produced with the mapped damage extent so the choice is informed.

    1 to 2 days
  2. 02

    Panel sourcing or moulding

    Replacement panel sourced, or a mould taken and a panel laid up in house where none exists.

    3 to 20 days
  3. 03

    Removal and inspection

    Panel released, penetrations catalogued, framing inspected in full and repaired as needed.

    2 to 6 days
  4. 04

    Substrate and bonding

    Substrate replaced and the new panel bonded under controlled temperature and full area clamping pressure.

    3 to 8 days
  5. 05

    Refit and refinish

    Windows, lights and rails refitted with new seals, then refinish blended into adjacent panels.

    4 to 12 days

Common Problems and How We Solve Them

No one makes the panel for my coach anymore.

SolutionWe mould one. A pattern is taken from the mirrored side or a donor and the panel is laid up in house with a matched reinforcement schedule.

The replaced panel looks newer than the rest of the vehicle.

SolutionA blend problem, not a panel problem. We refinish into adjacent panels rather than stopping at the seam.

A previous panel replacement is separating at the edge.

SolutionAlmost always inadequate clamping pressure during bonding, or bonding done at the wrong temperature. Both are why we do this work indoors under controlled conditions.

Frequently Asked Questions

How much does full panel replacement cost?

Cap replacement runs $4,500 to $25,000 and up at 30 to 120 labor hours. Sidewall sections fall within the $1,500 to $20,000 and up delamination band depending on size and whether the panel has to be moulded.

Can you make a panel that is no longer available?

Yes. We take a mould from the mirrored side or a donor panel and lay up a replacement with a reinforcement schedule matched to the original.

How long does panel replacement take?

Two to eight weeks. Panel sourcing or moulding is the long pole, and bonded adhesive cure time cannot be shortened.

Will the new panel match the rest of the coach?

Yes, because we refinish and blend into the adjacent panels rather than matching to a factory code and stopping at the seam.
