Not dependable at all. Would not recommend this company at all. First of all when i called no one answered the phone i had to leave a message on a machine. Then the woman that called me back sounded very rude and unprofessional. Then the plumber never made it to the appointment i made until the next afternoon and when he got there i almost did not let him in my business doors he looked like he just got out of jail and besides that he smelled. Then he quoted me a price that we agreed on but when the job was done my bill was almost TRIPLE the price we agreed on. would not recommend this company.
