"I have what turned out to be a 30 year old water heater replaced by this great company and they did it the same day of the quote. The installer had the water heater I wanted on the truck and did an excellent job of putting in the new unit, cleaning up and even replacing copper flex tubing and installing a new overflow pipe out of copper as well, no additional cost. This company specializes in water heaters and couldn't do any additional work on supply lines and they clearly state that on their website. I didn't need that type of additional work."

"Perfectly. They cleaned everything up, explained how the system worked and how often it needs attention, and hauled away the old hot water heater. They arrived on time, worked steadily, and finished before dinner time."

"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."

"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."

"Jess and his crew did a great job recently repiping my house, both the water supply and drain lines. Jess is easy to work with and very responsive. His price was very reasonable. He came back promptly to fix some very minor issues I found (tiny leaks from the kitchen sink drain and from one of the outside faucets). Everything is fine now. The sprinklers in my backyard work better now because they're getting more pressure than they got from the very old galvanized pipes that were replaced. I'm happy to recommend him."
