Your Five-Year Guarantee Is an Unfunded Cost Code
The gate is dragging again and your truck is out there for the third time, and nobody is billing anybody.
Callbacks on most trades cluster in the first few months and then taper off. Fencing callbacks run on a frost cycle, because the soil has to move before the post does, and a gate has to swing a few thousand times before a hinge or a roller tells you anything. The failure curve therefore peaks long after retainage is released, and the code obligation on a powered gate operator has no end date at all.
The size of it
Every warranty trip is a full mobilization with truck, crew, and sometimes the auger, and none of it gets charged to a job. The job that looked profitable at closeout keeps losing money for years with nothing on the report saying so, and a gate operator out of compliance with UL 325 can void insurance coverage if somebody gets hurt on it.
No published benchmark reference breaks this trade out on its own. CFMA reports at NAICS level, and at that level this trade rolls into a broader bucket with several others. That's why this page carries mechanisms and no margin figures. It reports inside NAICS 238990 All Other Specialty Trade, so there's no fencing margin figure to put in this box. The 48 trades that do publish average 7% net profit at $1M–$5M before taxes, which is the nearest reference point worth anything here.
Fence contractors advertise multi-year workmanship guarantees as a selling tool, with five years on installation and structural integrity being common. Those guarantees cover the two failures that run on this trade's own clock: post movement and misalignment from soil settling and frost heave, plus gate sag. Wood adds warping and cracking on top of that. Automated gates carry a second tail, because UL 325 and ASTM F2200 put entrapment protection, sensing edges, photo eyes, and emergency stop on the installer, who is also expected to set up ongoing testing and maintenance of those devices. None of it fails on day one. It fails a season or two later, on a job your books already closed.

What fencing owners ask
Warranty callbacks on gate operators and post heave?
The gate is dragging again and your truck is out there for the third time, and nobody is billing anybody.
What does it cost?
Every warranty trip is a full mobilization with truck, crew, and sometimes the auger, and none of it gets charged to a job. The job that looked profitable at closeout keeps losing money for years with nothing on the report saying so, and a gate operator out of compliance with UL 325 can void insurance coverage if somebody gets hurt on it.
What do I do first?
Open a warranty cost code and charge every callback back to the original job number with real hours and truck time, so the tail sits on the job that created it.
Are there published benchmarks for fencing?
No, and this site won't print one. No published benchmark reference breaks this trade out on its own. CFMA reports at NAICS level, and at that level this trade rolls into a broader bucket with several others. That's why this page carries mechanisms and no margin figures. In the surveys it rolls into NAICS 238990 All Other Specialty Trade, so the closest honest reference is the 48-trade table, where net profit at $1M–$5M averages 7% before taxes. Read that as the neighbourhood, and read your own job costing as the answer.
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.
