That broad reach hasn’t been all positive for those who work with the company, though. One contractor wrote they believed there is a “Horrible culture at Emcor/USM. They’ll tell you one thing and do another, classic bait and switch. Then they find every excuse not to pay you! As soon as they find a cheaper solution they fire you, their service is awful, they couldn’t care less about their customers or vendors and they have no clue how to treat people.”
“Horrible invoicing system,” added another contractor. “Takes forever to get paid. I’m losing money and time right and left with this group. Terrible.”
