What reviewers report — the concerns
Other directories bury these. We think you should read them before you call. Every concern below comes from the reviews it cites.
Failed to honor 2-hour overnight dispatch promise: customer stayed up all night, follow-up call was never returned, technician arrived next morning without communication
“Unprofessional. Also not 24 hours like advertised, BEWARE. I called for a plumber at night, person on the phone said someone was dispatched and would arrive in 2 hours. I stayed up all night waiting and no one arrived until the next morning!!! At some point, I called back to ask for the status, someone said they would check and call me back. They NEVER called me back.”
Scheduling follow-through inconsistent: online request ignored, two separate appointment windows missed without proactive contact from company

“They get an extra star for coming out quickly to do a quote but that is where it ends. Originally was told I would receive a quote on Tuesday followed up on Wednesday with a text and received a response that they will get back to me on this. Followed up on Thursday with another text and no response and then a phone call on Friday and left a voicemail. Perhaps something happened with my point of contact, things …”
Positive
“I had a really great experience with Precision Flow Plumbing. When Esther first got involved with the project, you could immediately tell how much she genuinely cares about her customers and the quality of the work. She took the time to explain everything clearly, answered all of my questions patiently, and made sure I felt comfortable with the plan before anything started. The technicians, Juan and Minor, were …”
“Adlon and the crew are there for businesses and homes when other plumbing companies won’t respond. They’re responsive on weekends and always as friendly and helpful on the phone as possible. They will often help you find the most budget friendly way to fix your problem. Worked with them multiple times.”
