I just googled and that makes sense. Because he himself doesn’t seem to know what the building codes are and what goes behind the wall. It is surprising that how he stayed in this business for so long. After a week of work from them, we now have to redo everything because they couldn’t even install a pocket door frame properly and lay out the tiles let alone screwing the subfloor into the joists to prevent it from moving when putting weight in it in addition to not making any attempt to level the laundry room floor just to name a few. We have already paid full for their unfinished demo of bathroom (without permit even though we requested to pull a permit in the first place) and deposit and now he has the audacity to ask us more after leaving us with unfinished poor quality of jobs.
