A Freeze Event Hits A Year After Final Payment
Ten grand of pipe froze over a long weekend and turned into a claim, and the crew that went to fix it came off a billable job to do it.
Your warranty exposure is measured in seasons, because the failure mode needs weather before it will surface. When it does, water discharges into a finished building, so a small defect in your work turns into a large claim against somebody. No other trade's callback runs a fire watch meter while the phone is still ringing.
The size of it
With no warranty reserve on the balance sheet, a freeze event hits the current month at full cost, in the same month you pull a crew off billable work to go handle it. Emergency callout labor is the single most commonly unbilled work in this trade.
There are three callback tails in fire protection and none of them behaves like a punch list. Freeze is the first: a wet system in a marginally conditioned space, an attic, a canopy, a loading dock, a stair tower, or a dock door soffit, breaks in the first hard freeze, which is 6 to 14 months after acceptance. The pipe repair is small and the water damage below it isn't, and the fight is always design defect versus the owner turning the heat off, with your GL carrier sitting in the middle. Second is corrosion: dry and preaction systems trap air and water, and MIC pinholes emerge at 2 to 5 years, past the one year warranty and well inside the argument. Third is impairment: any accidental discharge or mechanical damage puts the system out of service, and out of service means a fire watch billed by the hour until you restore it, dispatched by whoever called at 6am with no PO behind them.

What fire protection owners ask
Who pays when a sprinkler pipe freezes after the warranty period?
Ten grand of pipe froze over a long weekend and turned into a claim, and the crew that went to fix it came off a billable job to do it.
What does it cost?
With no warranty reserve on the balance sheet, a freeze event hits the current month at full cost, in the same month you pull a crew off billable work to go handle it. Emergency callout labor is the single most commonly unbilled work in this trade.
What do I do first?
Open a numbered service work order for every callout, including the 6am ones, and require a signature on site before the truck leaves.
What are fire protection contractors supposed to be making?
Fire protection 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 11%.
Which part of the system fixes it?
The step is number 03, overhead calculation. What indirect cost really comes to at your size, and the rate your estimating template should be carrying. It comes from chapter 3 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.
