Northlake Plumbing replaced my water line (service to the house). They were respectful, considerate, and had high standards. I had called at 5:30 pm or so one evening, and by 4:05 pm the next day they were done! I had some picky requests about the way the sod was put back over the holes, and they worked with me, even redoing a portion of the work already finished. They weren't the cheapest quote I got (slightly higher than my other option), but I was impressed by the salesman, who, with another team member completed the work. Their conversation, even when something went wrong, was free of offensive language. The original employee/salesman delivered as promised, maintaining a positive attitude the whole time, though it was clearly grueling work.
