Subcontractor sent for water heater install arrived unprepped (no drop cloth), worked alone on a 50-gal heater, and scratched the basement floor — reviewer notes he did not appear to be a direct employee.

The evidence — in reviewers' own words
Critical
“Short story: The worse service I have ever received. Lower than industry service with higher then industry level charge. Just stay away and find someone trustworthy. I looked into other low rating reviews and there seems to be a pattern of misleading customers with prices and later charge way over. Long story: Plumber came to check my water heater. He did not check anything except flushed the heater, a $50 job if …”
“Had two small pinhole leaks in cold water supply to guest bathroom. The charged me $175 to come out and give me an OUTRAGEOUS estimate. $499 PER LEAK!!! A thousand dollars for maybe a foot of copper pipe, 4 couplings, and a hours work for anyone competent. I see why they charge the $175 up front. Only the most desperate customer would put up with their business practices. Not me.”

No apology for running late. He then said he sent a text to me but didn't get a response. I never received a text and I found it odd that he wouldn't call a customer instead of texting to let them know the technician is running a half …”

From scheduling to completion, the whole experience was seamless, timely, and professional, leaving us feeling confident in …”
“I was contacted right away and my job was scheduled in a timely manner. The plumber arrived at my home and was professional, courteous, , and efficient. He explained to me where the leak in my toilet was coming from, what he would need to do to fix it, and an estimate of how long it would take. He completed the job in less than anticipated time and left my bathroom looking better than when he arrived. He left …”
