These are unlicensed hacks that throw up junk work that fails multiple inspections. I worked with them a matter of days and was sickened by what I saw and when I pointed things out was ignored to the point of losing my temper. I would not hire any of these hacks to even hang a flashlight in an outhouse.
Gave me date to fix my issue. Never showed up, and they never returned multiple phone calls. I ignored the low rating they had because I wanted to go local. My mistake! Don't let it be yours.
If the driving skills of your workers are any indication, I would question your quality.
