"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."

"Glen was great. He explained everything he was doing as I watched so I could learn how to drain the water heater myself. He checked the pressure in all the faucets & cleaned up afterwards. I’d definitely hire Hosack again...and request Glen."
