Block laid in month two, retention released in month twenty
You set structural block right behind the foundation, and the ten percent held on it sits untouched until substantial completion, a year and a half later.
Most trades earn where their retention sits, late in the job, so the hold and the work sit near each other on the calendar. Masonry goes vertical early and finishes late under a single number, which stretches the distance between earning and release further than any other subcontract on the building. The block scope alone can be held longer than some subs are even on site. Your estimator sees the bid margin and never sees the eighteen months the cash was gone.
The size of it
On an 18 to 24 month building, ten percent of your largest and earliest revenue is unavailable for roughly eighteen months, while the labor that produced it went out the door weekly back in month two.
On a load-bearing CMU building the mason follows the footings, and structural block is usually the biggest single piece of the contract value. Then the same subcontract brings you back for veneer after dry-in, and back again for tuckpoint and cleandown at punch. The whole scope runs under one contract with one retainage account and one release at substantial completion. So your earnings pile up in the first third of the schedule while the release waits on the last day of the last third. The payroll that produced that block cleared the bank in month two.

What masonry owners ask
How to track masonry retention when block is done a year before the job?
You set structural block right behind the foundation, and the ten percent held on it sits untouched until substantial completion, a year and a half later.
What does it cost?
On an 18 to 24 month building, ten percent of your largest and earliest revenue is unavailable for roughly eighteen months, while the labor that produced it went out the door weekly back in month two.
What do I do first?
Build a retainage aging report keyed to the month the work was earned, not to the job, so you can see how old your oldest held dollar really is.
What are masonry contractors supposed to be making?
Masonry runs 21% gross margin, 14% overhead and 7% net profit before taxes at $1M–$5M. The all-trade average is 7%, so this trade sits right on it. The CFOS target is 10%.
Which part of the system fixes it?
The step is number 05, software and bookkeeping alignment. Live job costs inside thirty seconds, with the bookkeeping cadence that keeps them true. It comes from chapter 5 of CONTROL: The Construction Financial Operating System.
