Customers say: Super punctual
"Friday night noticed water on garage floor in and around area of pressure valve of 15 year old water heater.
Saturday called at 7:45 am, arrived 10:30 am work completed 11:45 am.
Saturday night noticed water on garage floor in and around pressure valve of new water heater.
Called Sunday 8:00 am, owner responded within an hour. Determined problem (not new water heater but it was just a matter of time) and provided immediate solution at no additional expense.
OK, let me recap:
- First call professionally responded to and repaired in record time.
- Second call on a SUNDAY with response provided by OWNER. Are you kidding me?
Customer service way above and beyond any expectations. If you need plumbing services CALL THESE GUYS!!!

"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."

"Everything went ok as far as I could tell, but yesterday a plumber told me the gas line was not large enough and that is why the water heater is not working properly."
