"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."

"My water heater was leaking profusely all over my basement floor and needed to be replaced immediately. Usually getting someone to come over in an emergency is not easy, but when I phoned Arreaga Santos Plumbing Santos said he would come over right away, which he did. My heater is in a difficult place and hard to get to, but Santos and his assistant removed it with ease. Not only was this done fast, the minute details that he attended to were performed with great care and very high quality. Also, he's a very nice guy. Based on the entire situation there is no other plumber I would use in the future. Just call him, you will be as happy as I am."

"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."
