"Patrick was promptly in figuring out what our issue was. He was able to rod the line and get the water to start draining out. Explained why the line clogged and what to do to help it from happening again. He will be my go to plumber"

"It couldn’t have gone better! Carl was experienced, knowledgeable and friendly. Plus, he smelled gas which is why he replaced the valve on my water heater. It was a great visit!"

"The job to replace water heater was done well overall. They claimed that an additional plumbing job was mandatory and that they would not proceed without that. There was no way for me to verify whether this was mandatory or not. I had requested them to wait for me to review the additional work (I drove home while they begun the job). I may have been 3-5 minutes late and they were gone. I requested that I would appreciate if somebody comes by and shows me the additional work and the cost justification for it."

"We actually had called Emanuel Brothers first since their name was on the water heater. But, after the amount of time and money they quoted us I decided to check Angie's. We had John come out and take a look and he told us he could do the same work for almost $800.00 less! I can't say I didn't have some trepidation. First, just how is it possible to do so much less work than we were told would be necessary (we had 2 water heaters. Neither of which worked after nearly 20 years, that had to be removed first to make room). And, for so much less. Emanuel Brothers were so perplexed by our situation that they had to call the boss to come out and explain everything to us. But, John had this "no problem" kinda attitude. Both refreshing and disconcerting. But, in just a couple of hours he had not only delivered a new water heater, he had the other 2 removed and the new one installed. And its been working flawlessly.
