The evidence — in reviewers' own words
Critical
“Very unreliable. They rarely keep to the 4-hour service window. Subscribers are not a priority. I made the service appointment a month before the scheduled date and they still failed to show up. Decided to cancel the service agreement and be done with them.”
“This was one of the worst service experiences I have ever had with a plumbing company. I scheduled a service call and waited more than 34 hours for someone to come to my site. During that time, I was told a technician would come to diagnose the issue, and I was charged a diagnostic fee. After all that waiting, I was finally told that they do not perform commercial plumbing work. This is something they should have …”
Positive
“Kemar Lewis, the dispatcher technician, led with professionalism. He explained the solution in detail and he even saved me some money and time by finding an alternate route to access the plumbing pipes without having to tear apart my bathroom tile. His service, mannerisms, and workmanship were excellent.”
“Last Saturday, I finally contacted Len the Plumber because my thermostat needed checking. They immediately dispatched a technician, Mr. H. He diligently identified the root of the problem and fixed it. Before leaving, he answered all my questions and explained the options I had for protecting my HVAC system. I'm so glad I can count on this amazing company whenever I need help. They never disappoint.”
