Not only he is a bad plumber, he is an dishonest one. He took the money from me and never did the job. I had an plumbing issue so I called him. He came and charged me about $270 for a leak and also he was supposed to put the drywall back. After 30min. of work he said the leak has been fixed. He was supposed to come back in 2 days to close the drywall as well since he open the wall because of the leak. I paid him in full and he said that he will be back for the drywall. After one day the leak came back again. So I called him. He said he is too busy to come back. He told me that he will call me in 2 days to schadule a time to come. After 2 days he never called. I called him several times and he picked up the phone once and after hearing my voice he hanged up. I texted him but no respond. I end up bringing in a different plumber. I texted him and ask him to at least pay me back for the drywall portion of the money. I gave him 3 weeks to pay back but nothing. Stay away from this plumber. He is a ripoff artist. He also does construction so I would not use him for anything. Stay away from Nahum Hernandez from Sunland.
