The apartment I live in contracted Sheen Plumbing to install vents for dryers on the first floor. They were let into the unit because no one was home. They stained our newly washed carpets with dirt from their shoes, scratched our expensive washer and dryer appliances and there was evidence they even used our restroom. I've called and left 3 messages but never get a response. This company is extremely unprofessional and I would never wish them to do any work in my home.
