The crew is gone, the area looks done, and three weeks later somebody discovers the penetrations were never firestopped and the punch items were never addressed. Almost all of this is preventable at closeout, and almost none of it is preventable afterward.

Finished is not the same as complete
The crew is gone, the area looks done, and three weeks later the general contractor discovers the penetrations were never firestopped and the punch items were never addressed. This is one of the most common and most expensive patterns in subcontracted work, and almost all of it is preventable at closeout.
Walk it before they demobilize
The single most effective control is a walkthrough with the foreman while the crew is still on site. Anything found in that walk gets fixed for the cost of labor already mobilized. Anything found afterward costs a return trip that somebody is going to argue about.
Schedule the walk as a condition of the closeout, not as a favor to be requested.

A defined finish line
"Complete" has to mean something specific per trade: punch items cleared, penetrations sealed, labels applied, testing done and documented, as-builts marked, warranties and closeout documents submitted, area cleaned, surplus material removed or turned over. Without that list, every sub declares themselves complete at a different point.
Tie the money to the list
Retention exists precisely for this moment, and it only works if it is actually held until the list is satisfied. Releasing it because the work looks done is how leverage disappears exactly when it is needed.
Closeout documents are part of the work
Test reports, warranties, operation manuals, as-builts and training. These are contractual deliverables, not paperwork, and chasing them six months later from a sub with no remaining financial interest is one of the least productive activities in construction.
Check what they left behind
Before accepting the area, look at what the departing trade did to the work of others. Damage discovered after demobilization becomes an argument with no witnesses, and it is usually the following trade who gets blamed.
Make the callback obligation explicit
Confirm in writing who to call, how fast they must respond during the warranty period, and what happens if they do not. A subcontractor who has been paid in full and has no defined obligation responds on their own timetable.
Where to start
Define what complete means per trade, walk the area with the foreman before demobilization, hold retention against the list rather than against appearance, collect closeout documents as work rather than paperwork, inspect for damage to other trades, and put the callback obligation in writing.

We help builders define trade-by-trade completion, run the closeout walk before demobilization and hold retention against a list instead of an impression.
Frequently asked questions
What should a subcontractor closeout include?
A defined finish line per trade, because without one every sub declares themselves complete at a different point. It should cover punch items cleared, penetrations sealed, labels applied, testing done and documented, as-builts marked, warranties and closeout documents submitted, the area cleaned and surplus material removed or turned over. Walk the area with the foreman while the crew is still on site — anything found in that walk gets fixed for the cost of labor already mobilized, and anything found afterward costs a return trip somebody will argue about. Schedule that walk as a condition of closeout, not as a favor to be requested.
How do I make sure a subcontractor comes back for warranty work?
Hold retention against the completion list rather than against how the work looks, because retention exists precisely for this moment and only works if it is actually held. Collect the closeout documents — test reports, warranties, operation manuals, as-builts and training — while the sub still has money outstanding, since chasing them six months later from a company with no remaining financial interest rarely succeeds. Then put the callback obligation in writing: who to call, how fast they must respond during the warranty period, and what happens if they do not. A sub paid in full with no defined obligation responds on their own timetable.
