What I see from that picture is they did not stop the new floor in the middle of the door jam. There's a gap in the flooring, that's not 1/4 round, it looks like cove moulding, or it's some funky form of ogee installed upside down it should have been placed between the two door cases not over them, it also needed to be back cut at a 45 deg. angle not streight cut, it should never have been what looks like the cheap looking peel and stick wood grained fake wood moulding. It should have been real hardwood stained and sealed to match the flooring or simple paint grade and painted t match the trim as suggested.
If I had of seen one of my employees do a job like this I would have sent him or her home ripped it out myself and redone it at no cost before you ever saw it, (hope fully).
If the boss saw this and has no idea why your making a big deal of it, then there blind and stupid.
That whole job was a carpentry 101 job. I hope you had no future plans to use them again.
I took a look at the other pictures you down loaded and without a doubt that's the worst trim job I have ever seen. I would never allow them back on the property.
One last thing, was that the origanal baseboards?
It looks like someone used casing instead of baseboard. What that does is make the baseboards even with the door casing. The base boards should have been thinner so there was a step to end the 1/4 rds.
Where all stupid, just in different subjects.
