Kaiden Nunez
October 2, 2026Justin was great to work with. He came out, took the time to look over my Navien tankless water heater, explained what he was seeing, and gave me honest guidance on my options. He was professional, responsive, and easy to talk to. I appreciated the way he handled everything and would definitely recommend PowerHorse Plumbing to anyone looking for a plumber who actually takes the time to help.

September 28, 2026Justin was incredible nice, professional, and did a perfect job installing my new kitchen faucet and gave me a great price. Justin took the time to make sure everything was working beautifully and cleaned up completely before leaving. It’s hard to find reliable service like this. “A Ten Stars Plumber!”
Adam Choi
September 2, 2026I’ve worked with Justin multiple times, and one thing that has always stood out is his transparent pricing — you never end up paying more than what he quoted, with no surprise charges. Before this job, he sent two separate quotes, each with a clear scope of work, so I knew exactly what each option included and what it would cost. Beyond the pricing transparency I already expect from Justin, what impressed me most on this job was his experience and attention to detail. He came for a broken pipe replacement, but recognized that the leak pattern didn’t match the broken pipe and ultimately traced the issue to the house trap. Justin also understood the urgency and responded right away — from my initial call to the completed repair was only two days. Communication was excellent, he provided clear proof of the completed work, and he was patient in explaining the issue and available options. Fast, meticulous, transparent, and highly professional. Highly recommended.

March 27, 2026Justin and Ed did a great job. I had a bunch of faucet and shower fixes, along with some toilet and laundry line issues to be addressed. Within 24 hours of contact my request for an estimate was done and within the week the work was done. PowerHorse takes pride in their work. They put cloths down in their work areas and cleaned up when they were done. They were pleasant and polite. I will definitely put them in my contacts for future plumbing needs. I am very happy with their work.

March 25, 2026PowerHouse Plumbing is an A++ Business! Very professional! I had a pipe break and they came out asap to stop the leak and determine what they would need to make permanent repairs. The owner came out along with one of his top plumbers first thing this morning and was done in about an hour. I was provided several different fee options depending on my budget which was great. They even removed and hauled away all the soaked/damaged insulation!! Went above and beyond! I’ve already forwarded their contact information to my neighborhood thread where we share info and great contractor recommendations when we come across one (rare sad to say)! But I know have a great Plumber -yah!!! Thanks, TerriG

March 17, 2026Prompt, courteous, and professional. These guys are topnotch. They took care of an issue at one of my investment properties. Reasonable and communicated throughout the job. All this and fact that they made it a flawless, stress free experience for me means they will be called for any plumbing issues at any of my properties.
