"It started off bad because I had the water heater installed, submitted my paperwork for my rebate for the installation and then my rebate ended up not getting honored because the water heater that was installed didn't qualify for Spire's rebate. Turn's out that the water heater that would fit my location as well as satisfy Spire's rebate, I would have had to wait 5 to 6 weeks for that specific water heater so, the owner of Hosack's Plumbing cut me a check for the amount of the rebate and the amount over time that the new water heater would have saved me. Not the perfect situation but, that was a win win for me as well as Hosack's Plumbing because a good water heater was installed just not one that would quite fit the Spire requirements for the rebate! Hence we didn't need to take a brand new water heater out and replace it with another water heater that was just .05 UEF Higher!"

"Fantastic job installing my new water heater. The employees at Anton’s are efficient, professional and really likable people. They arrived on time and got the job done effortlessly. I also loved how they treated my home like it was their own by making sure nothing was damaged or ruined. They cleaned up everything and it didn’t even look like they had been here. I give Anton’s an A+ for the installation of my water heater."

"I appreciated he found a way to replace the faucets and shower by going through the kitchen wall so as not to disturb the tile. Also appreciated his honesty about his recommendations concerning the tile."

"the technician from zoom drain was great. He led me through the entire process, including clearing the clog, showing me with a camera the roots that caused the blockage in my sewer main, water jetting the line to remove the roots, and showing me the cleaned out line after he was done. 10/10 service."
