I called Onyx and another plumbing company in St. Louis Park to get estimates for running a steel line partway to my replacement gas dryer (from a Google search, I was under the impression that the existing copper line was not allowed for natural gas, so Id need a longer steel line to get close enough to use flexible stainless line). I sent both plumbing companies the same photos. John at Onyx informed me that I didnt need any work because the copper line (clearly visible in the photos) was in fact acceptable. The other plumbing company instead quoted $585 for the work! I think that says it all. Thanks again, John!

ONYX PLUMBING & GAS's reply

Thank you for your great review, Justin. We are glad that John has provided useful advice over the phone without having you to paying something that’s unnecessary to fix. We believe honesty and integrity DO matter to our valuable customers like yourself, and we take pride in committing ourselves to those values! Feel free to reconnect us for your future projects. And thank you again for choosing onyx plumbing and gas.

Zack and his colleague were truly exceptional. They demonstrated honesty and completed their tasks promptly. Furthermore, they left the area tidier than they found it.

I was able to get an appointment the next day when I called & Trenton did a great job at replacing my outside spigots, adding a shut off valve in my finished ceiling (also helped size the hole for the access panel I ordered), and updating my outdated laundry room sinks faucet & valves. He went and beyond to explain everything, including what to do in the winter. Will definitely be recommending and using Onyx again for future projects!
