"Aleman Plumbing contacted me right away for an appointment to look at my water heater. Their quote was advantageous compared the the other I received and they were able to schedule the work immediately. My water heater was in a difficult location and I also needed to replace a pressure control valve but Carlos got it all done very well and was great to work with."

"Drew from Legacy Plumbing came out IMMEDIATELY to our rescue because not only were all toilets and showers unusable because water would flood downstairs but we had a birthday get-together with family happening within the hour. Drew was very knowledgeable and quickly fixed our clog and we needed a replacement part for an obvious leak. Legacy Plumbing is super honest, and you don't feel like you're getting ripped off with unnecessary b.s.. This is the second time we've called and because of the great job he did on our last major issue with our old pipes, we called him again. The cleanliness, effeciency, and honesty of this company is why I felt compelled to rave about them and let people know in a review. Definitely my plumber and business to recommend from here on out."

"The plumber can over the same day and examined what needed to be done. Installation of a leak detector. A quote was generated and it was approved. The plumber arrived on time Sat morning and had everything ready to go. Well organized. Work was completed on time and we only had to have the water off for 2 hours. Not cheap but reasonable/competitive and they show up and get it done."

"Hector and his helper got the old water heater taken out, a tankless one installed, and a water softener and filter installed in one day. Normally this job would take about a day and a half. Hector is very easy to work with, answers questions in a way that’s easy to understand, and has competitive rates. I highly recommend HB Plumbing."
