September 16 · Erik KralovetzThis is the third time I use your services. I want to express my gratitude for your work. For the quick response. Of course, I will use your services in the future.
September 09 · Joan Marie Miglautsch$ 581.70 ??????? small vanity sink needed new water lines and shut off valves , plus a 5ft pipe had to be opened with machine,, this process took over 3 1/2hrs do to slowness of plumber and charged 396.00for labor + 180.00 for parts and an exchtra 69.00 for the machine, which took 10 minutes to set up and use,,, with thtotal bill with tax being 581.70 this charge also included a trip back to warehouse because dint have parts with him,,,, never again would i use this service, and to make matters worst the sink shut off valves LEAK!!!!!! Ben kielich 10/13/2023 offered to take off 50.00 of bill, because fely quilty!!!! and they were.
January 31 · dave kielichExcellent, knowledgeable service. Professional and direct. Punctual and Responsive to your issue. Lower charges than those who drive a large truck up to your house and try to sell you all new items on inflated markups according to a price book. These guys will help you save by repairing your hardware vs. replacing brand new. Tim on the phone was great and followed through. The technician that arrived was polite and professional and knew what he was doing. Cleaned up and did a nice job. Did not over charge.
March 27 · Jerry ChiuI called them in an emergency type need and within an hour they were on the way and in less than an hour after arrival they were done and toilet was working perfectly, no more leaking! Super fast and responsive, very friendly and compassionate to my situation, and tidy too!! Thank you!
