"Everything went great. They were able to set up an in-home estimate. Derrick is courteous and professional, and was able to get me an estimate quickly, and was even able to accommodate the work the same day, cleaned up after the work, and walked through the features of the installed hardware with me. Very highly recommended, and would definitely call them again for any plumbing work!"

"Pohlman responded quickly when my water heater leaked and quickly replaced it at a competitive rate. I asked for multiple quotes and they were one of the first to respond. I appreciate the work, although I would have preferred to know which water heater was being installed before they put it in."

"Perfect! Doug is an expert Plumber that knows private water system. He removed the old equipment and installed the new. Everything is still working great. The work was done almost 13 years ago. We used all Top of the line Gould Equipment. I probably should call Doug to replace it again because breakdowns with the water system can leave you stranded."

"I found my water heater leaking just after 9 AM. Called and was given a quote over the phone. They arrived by 11 AM and were done by 2:30. Very good service. They covered my floors with drop cloths, cleaned up nicely and hauled away the old unit. Price included the new water heater, a new shutoff, valve, fittings, drip pan and expansion tank. Professional service done very promptly at a fair price. I was extremely satisfied!"
