Pangching and his workers did sloppy work which had to be redone properly by another contractor. They did not cap open pipes, so the house filled with gas fumes. They had no clue about mold resistant drywall (and it was a hack job anyway) so that was taken down and redone by another company. They did not isolate rooms so dust filled the house and heating system and were not educated about insulation materials or leveling uneven floors.
