When I needed my Septic tank cleaned out, they took care of everything while I was at work. Super convenient.
There plumber showed up 2 hours late. Then Sat in his truck in my driveway for a good 20 minutes. After confronting him about it and asking nicley why he wa so late hee stormed off and said he is leaving. Totally unprofessional in the way the treat customers, we called the office to complain and they didn't seem to care either. Told me they could send the same guy back another daily if we wanted
Absolutely terrible service. Technician was sanding and plowing instead of coming to our scheduled appointment without any notice to us. Showed up two hours late, sat in their work van for over ten minutes, when my husband went out to his van to let him know which entrance to come to when he was ready, he was completely ignored. Then when the technician came out we asked what the deal was for this whole situation and asked if it was a problem? We of course said yes as we were assured this appointment was not in conflict with anything he may have had off company books. He then turned around and got in his van and left. The company offered zero assurance of rectifying the situation and said the same technician has a very slight possibility of coming back but is pretty busy. Will never use them or recommend them to anyone. Absolutely awful all around.
They installed new piping that connected two commercial buildings and a house to the towns sewersystem . Worked late untill finished.
