I've used Albert Nahman Plumbing and Heating several times and I'm quite happy with them. I have a rental apartment, a four-plex, and I've used them for my units anytime a plumbing problem comes up. They've done things like cleared drains, stopped leaks, replaced shower valves, and checked gas lines. I had them at my house once when I had a blockage in my sewer line and they flushed it out for me. I find them quite reliable. The technicians have always been very communicative and responsive. They've also been accommodating. I usually get an appointment within a couple days when I call. I think they might be more expensive than some other plumbers, but I use them because they're reliable. I'm always very happy with their technicians because they respect my property, they respect my time, and they know what they're doing.
