Commercial carpentry has to survive doors slamming all day, carts nicking corners, and cleaning crews wiping finishes constantly. Pretty is not enough. The install has to stay tight.
That starts with accurate openings. Out-of-square frames and rushed shimming show up later as rubbing doors and failed hardware. Take the time to level, plumb, and fasten correctly the first time.
Trim and finish carpentry should match the traffic level of the space. High-touch areas need cleaner joins, better fasteners, and finishes that can be maintained without looking worn after a month.
When carpentry is part of a larger repair or TI package, sequence it with drywall and paint so you are not cutting finished surfaces twice. Good carpentry is as much about timing as it is about skill.
