"Installers were professional and went out of their way to complete work in one day so we had hot water and I didn’t have to take any additional time off work. Tˇhe replacement was approximately 60 days ago and the water heater is working Great"

"Jaymie first visited to review our need for correcting a pre-existing faulty installation of a tankless water heater. He grasped our concerns at once, joined us in brainstorming a relatively simple solution, and produced a financially reasonable bid on the spot. We accepted it as far more reasonable than other bids. He arranged to have the work performed by his company within a few days. At the appointed time, Jaymie himself arrived to do the job, which pleased us greatly since he already knew exactly what needed to be done, making it unnecessary to brief a new workman. He is a very competent, friendly, and helpful person. We would not hesitate to call on him for any future plumbing needs."

"Excellent from start to finish. Arrived on time, replaced our old water heater with a new one, left everything very clean and, from what I can tell, provided excellent workmanship at a very reasonable price."

"The day the service was scheduled did not go well. We were scheduled between 8 and 12, but they called in the morning to move it back to 10 to 2. I called them after 2 because we had not heard anything. The technician finally came around 3:45. I think it is very poor customer service to expect someone to wait all day for a service call. Once the technician arrived the service was done very professionally. He did find that they should have enlarged our vent with the install two years ago, and they will have to come back and do that. It makes me think they did not have proper attention to detail during the install. There also was an up-sale so that a $79 service call ended up costing us over $450."

"The plumber came almost at the end of the appointed time. When he arrived, he was fairly arrogant, and refused to negotiate despite coming from Angie's list. Lastly, he repaired the leaky line in about an hour, charging $530, and also did not provide the water plastic box for water line. We had to purchase one from another store. When I paid for the invoice, they didn't tell me that they are charging additional 3% with credit card. All in all, they did the work, but at a high price, and so so customer service."
