View our Google Reviews"Justin 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."
"PowerHouse 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 — I now have a great plumber!"
"I have hired Justin for a few jobs here at the MSPCA at Nevins Farm. He has done a fantastic job and helped us out when we were in need of a plumber same day. He is my go to plumber for all my jobs big or small. Don't hesitate to call — you will be impressed with his work."
