  • What Our Customers Say:

  • "Haller was extremely courteous, polite, and extremely respectful. When all was said and done, Rich sat me down and explained everything they did again. I appreciated that Rich seemed truly interested in making me comfortable in my new home and offered lots of advice beyond his specific work that he was there for. My husband and I will not hesitate to call Haller again. They will be our go-to-plumber for years to come. They were a pleasure to work with and everyone I talked to at the office was wonderful as well. Very polite, quick to return calls and help in any way possible."
