"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."

"It went amazing. Paid the extra bucks for emergency service, because of our smallish waterfall, looking leak, sprouting from a bathroom pipe, enough to puddle water onto our basement/laundry room floor. Initially, spoke to Chris, who was pleasant and upfront with the per hour fees, for emergency services. He sent us Tim, who was hesitant at first, due to the location of the leak, but his experience and knowledge, enabled him to decipher the location of our leak and fix it. A quick trip to Lowes, where he promptly returned and in 90 minutes, the job was done. A week later and the valve is bone dry. Yay!!!"

"Joe and Dan are very professional and have competitive prices. They did a stellar job removing our old water heater and installing the new one. They were enjoyable to work with and helpful with our questions/concerns. We definitely recommend Joe and Dan for any water heater needs. Thank you!"

"The work was done correctly, promptly and better than I would have done myself and I am a perfectionist. 2 faucet replacements (kitchen & bathroom), complete with new hoses and new valves and 1 new drain stopper, closely supervised by my elder cat. After the work was completed, the installs were tested for leaks. I was walked through all the work that was done and shown all the features (one I didn’t even know I had purchased). Humble & honest practitioner. Will definitely work with them again. Highly recommend for excellent, clean, meticulous service."

"I am incredibly happy with the outcome of our heating maintenance that Mr. Clay Phelps Liquide Assets LLC Plumbing and Heating provided for us this week. Mr. Phelps is an experienced and efficient professional. He helped us with setting up our water treatment tanks and repairing our baseboard heating system throughout the house. Mr. Phelps was on time for his appointment, and he was totally focused on doing the work in an excellent quality manner. The price for his work was reasonable. I am extremely glad to find this company for our future plumbing needs. We strongly recommend this company for their services."
