    St. Louis MO

    Bieg has provided service for us from a stopped up toilet to replumbing our entire house. Service has always been efficient, exact, area cleaned up after service. I have been particularly pleased with the service provided by Dave. He is friendly, professional, goes above and beyond, knows what he's doing, and makes sure the area is clean and ready to go when he leaves. He even once showed me how to clean a shower head. Using Bieg has always been an excellent experience and a highly recommend their services.

  • Cannon Utility Services

    Jody Crossno, Field Supervisor

    Called and spoke with Alex Thu. night to inquire about availability of emergency work, he called through out the day on Friday to check on when the site would be ready for repair, as soon as it was, a plumber, Dave Kohn showed up and got right to work. He was later joined by Dennis and the two of them worked as a team to fix three separate damaged areas. Both plumbers were professional, hardworking and quite humorous. We at Cannon Utility Services hope to never see them again as if we do, it means we have damaged another water line. But in our business it is only a matter of timing when we will damage a line. We know who to call and have the comfort that the job will be taken seriously by your company as it is ours.

    My plumbing issue started out as a nightmare but Bieg Plumbing came in and worked very hard and put my mind at ease. They were on time all the time and even cleaned up. The men really worked hard and I am very satisfied with the work.

    Tom, St. Louis Mo

    Bieg plumbing has done several projects around our house and I don’t hesitate to call them when we need some things done. They provide good estimates and they stand behind their work. We have never had to call them back after a repair was completed. Their work is always done well. Just as important , the people that tend to work for them are friendly and helpful.
