"Stephen was the plumber who was hired to address the bad hot water safety shutoff valve to my new washer and a new hot water tank installation. He also addressed a few other issues that we had not previously discussed including my very old hot water heater and the safety shutoffs to the utility sink which were no longer operable."

"They were up front with what is wrong. Provided explanation of the quote. Asked permission to get access to places. They explain the reasoning for the cost and the risks if ignored. Pricing was fair. Went above an beyond to solve the water heater issue we had. Even calling in an electrician to help with a fix. They were on-time to early on their scheduled appointments. Excellent customer service."

"I called Pohlman to replace my Gas water heater. I was very pleased with their service. They were very professional, came out on the same day, took the old tank with them and cleaned up well behind themselves, They finish the job in a timely manner and their price was fair. I would definitely hire them again."
