The natural law of construction decrees anything that isn’t done perfectly at one stage gets harder and harder to fix later. One small detail can take a lot of time and struggled to resolve in a satisfactory way. One item that can be hard is the pesky range hood ducts. Getting them located properly, cutting them in, and so on can be problematic in advance of cabinetry being hung. Here is one that caused me some pain when it was buried and not cut out soon enough. Was resolved by butchering the box and patching later by doubling up the inside top of box with a precise hole. Seemingly took forever to resolve and multiple visits to overcome. Just brain damaging and painful.
