Nine Feet of Wall, One Star Crack, and a Nineteen Thousand Dollar Supplement

This is a composite of a job shape we see constantly rather than an identified customer, but every number, finding and stage duration in it is real work.

What arrived

A 2019 fifth wheel, roughly 36 feet, single owner, well kept. Something had backed into the driver side just ahead of the wheel well in a storage yard. Twenty four inch dent, fiberglass cracked in a star pattern, no visible damage anywhere else.

The carrier estimate was $4,100: fiberglass repair, refinish, blend into the adjacent panel. Written from photographs and a walkaround, and entirely reasonable on that basis.

Day 1 to 3: assessment

Photographs inside and out before anything was touched. Moisture readings at the ceiling, both sidewalls and both slide floor joints. Tap testing across the entire driver side rather than around the damage.

Tap testing findings:

• Debonded area extended roughly seven feet, from eighteen inches behind the front cap to about a foot past the wheel well
• Two separate smaller zones higher on the same wall, near the roof seam, that were not related to the impact
• Elevated moisture at the forward slide floor joint

That last one was the finding that mattered most and it had nothing to do with the accident.

Day 4 to 9: initial approval

Estimate submitted with the tap test outline photographed and the moisture readings attached. Approval on the initial scope came back on day nine.

Note that we submitted the tap test findings with the first estimate rather than saving them for a supplement. Carriers respond better to a scope that grows once, with evidence, than to one that grows three times.

Day 10 to 13: teardown

Awning and rail off, trim off, skin off across the affected area, slide out.

Findings:

• Debonded area was nine feet, not seven. Tap testing had underestimated the forward end by about fourteen inches, which is a normal margin.
• Composite substrate, so no rot. Good news, and it kept the repair in rebond territory rather than substrate replacement across the whole area.
• Framing sound except two tube joints with corrosion where water had been sitting. Both needed repair.
• The slide floor edge was wet across about thirty inches and the substrate there had failed. Cause was a wiper seal on the forward slide installed with the lip facing the wrong way, almost certainly during a seal replacement done elsewhere two years earlier.
• Two aftermarket holes near the roof seam, poorly sealed, feeding the two unrelated debonded zones higher on the wall.

The awning rail fasteners were also elongated, which is a separate finding worth its own article and which we addressed while access was open.

Day 14 to 21: supplement

One package, seven working days to approval.

Approved lines, as submitted:

• Delaminated area rebond, 108 by 38 inch primary zone: 46 hours
• Framing repair at two tube joints: 9 hours
• Slide floor edge substrate replacement, 30 inch section: 14 hours
• Slide wiper seal set, corrected orientation: 6 hours
• Aftermarket penetration repair and reseal, two locations: 4 hours
• Awning rail removal, fastener repair and rebedding: 7 hours
• R and I of awning, rails, trim, lights and tank vent: 11 hours
• Refinish and blend, driver side: 11 hours

Total 108 labor hours at $210 per hour, plus paint materials at $55 per paint hour, body materials at $5 per body hour, parts, and 7.75 percent tax on parts and materials only. $19,400 approved.

Declined: nothing on this job, which is not universal. The two unrelated debonded zones near the roof seam were correctly excluded from the claim as pre existing and the owner paid for those directly. We separated them in the documentation rather than trying to include them, and that separation is part of why the rest went through cleanly.

Day 22 to 41: parts

Fifteen working days, the slide seal set being the long pole. Structural framing work started during this window because it did not depend on pending parts.

Day 42 to 60: the work

Nineteen working days at roughly six productive hours per day.

Sequence mattered. Framing repair first, because everything bonds to it. Slide floor edge rebuilt next, because the slide had to go back before the wall could be closed. Substrate cleaned and dried across the debonded area, which took longer than expected because a section near the slide had absorbed more water than the readings suggested. Rebond under pressure, in three stages because the area was too large to press in one.

Then aftermarket penetrations repaired properly, awning rail rebedded into sound structure with new fasteners, skin closed, refinish, reassembly with new sealing throughout.

Day 61 to 63: verification

Water test on the whole driver side, roof seam and both slide openings. Slide cycled fifteen times with current draw measured, which came back flat and in range, confirming the floor edge rebuild had not left the room sitting differently. Panel gap check. Photographs. Documentation package to the owner.

What the owner would have got for $4,100

A refinished twenty four inch area over nine feet of debonded wall, a wet slide floor edge continuing to rot, a reversed wiper seal continuing to feed it, two unsealed aftermarket holes, and elongated awning rail fasteners funnelling water into the laminate.

It would have looked perfect. Within three years the driver side would have needed panel replacement instead of a rebond, at $2,500 to $25,000 and up, and the slide would have needed structural work at $1,500 to $7,500.

That is the honest case for teardown, and it is why we will not quote a final figure on laminated impact damage from a photograph.
