Year Two Blisters Come Back to a Closed Job
The liner blistered in year two, the utility will only let you drain that tank in a low-demand window, and the job closed out two fiscal years ago.
For most trades a callback is a truck, a man, and a day. Yours is a complete recoat cycle on a structure that has to come out of service first, priced like a small job of its own. It also hits two fiscal years after you recognized the revenue, so there's nothing sitting on the balance sheet to absorb it and the current year eats it.
The size of it
A single lining callback on a $600K repaint runs $150K to $300K in containment, blast media, coating, disposal, and disinfection, on a job whose entire margin was $90K.
Two tails follow a tank off the site. An NSF/ANSI 61 potable interior lining blisters or disbonds 12 to 36 months after acceptance, and the cause traces back to surface preparation or dew point at application, both of which were yours. Fixing it means taking the tank out of service on the utility's schedule, full containment, re-blast to SSPC-SP10, recoat, recure, re-disinfect, and re-sample. The structural tail is differential settlement that turns up on the API 653 Annex B survey 6 to 18 months in, and the argument over whether the ringwall or the shell caused it defaults to you, because you built the visible thing.
Three moves, in order
Step 08: Standards and accountability
Five hours a month of owner time, spent ahead of the work.

What tank and vessel owners ask
Tank lining warranty callback cost two years later?
The liner blistered in year two, the utility will only let you drain that tank in a low-demand window, and the job closed out two fiscal years ago.
What does it cost?
A single lining callback on a $600K repaint runs $150K to $300K in containment, blast media, coating, disposal, and disinfection, on a job whose entire margin was $90K.
What do I do first?
File a complete coating QC record on every job: ambient and dew point readings, surface temperature, blast profile, dry film thickness, and holiday testing, signed daily. That file is the only thing that moves a year-two argument off your desk.
What are tank and vessel contractors supposed to be making?
Tank and vessel runs 23% gross margin, 15% overhead and 8% net profit before taxes at $1M–$5M. The all-trade average is 7%, so this trade sits 1 points above it. The CFOS target is 10.5%.
Which part of the system fixes it?
The step is number 08, standards and accountability. Five hours a month of owner time, spent ahead of the work. It comes from chapter 8 of CONTROL: The Construction Financial Operating System.
Josh Luebker ran commercial construction projects before he ran the numbers behind them, on data centres, military bases, hospitals, and high-rises. He wrote CONTROL: The Construction Financial Operating System, which is an eight-step framework for commercial subcontractors, and it publishes on October 1, 2026. He is a master electrician who moved into the office and kept the field vocabulary.
Sulphur Prairie Operations LLC maintains the benchmark reference behind these figures. Every edition is reconciled against the newest CFMA survey release before it publishes here. Where a figure changes between editions, the older edition keeps its year in the title so a citation to it stays correct.
