"Call in the morning, visit that afternoon with quote, installation next day. They didn't have our model in stock, so we got an upgrade to the next larger water heater at no additional cost. Installer was very knowledgable and friendly."

"Did a $59 consult only. Turned out the cost of repairing the old heater was almost as much as a new one, so we got a new one, and handled the install ourselves. Luis B was great, knowledgeable, friendly, didn't try to upcharge just to sell a heater, which we appreciated. Gave us an honest evaluation, several options, and was right on time. I will say, though, that the company failed to call me when he was on his way... not a big deal. All in all a good experience."

"This is the third time I have used Albert Nahman. This time was for a water leak with an unclear origin. They did a great job diagnosing the problem and took the time to explain what they found and offer options on potential fixes. I really appreciate the care their plumber took in tracking down the problem and providing a realistic quote for the cost and time to fix the problem. They also arrive on time and do a great job cleaning up after the work is done. A+++ company. Will definitely use them again the in future."

"Jesus repaired the leaking water pipes behind the shower valve. It was Sunday, but his response was quick and he showed up on time. I think he is the best honest plumber I ever met. He did a great job with reasonable price."

"In & Out is fast and professional. They bid our job in the morning, and were back that afternoon with new toilet tank flushing devices and had all four of them installed in our bathroom the same day. They took away the old parts and the boxes the new parts came in. They are knowledgeable, punctual and tidy. Should we have any plumbing problems, I would call them right away!"
