Best Brush Coating in Baltimore MD

Review Update (July 31, 2022):See original review below for context.After posting a review of my bad experience with Rotor-Rooter, multiple Rotor-Rooter employees at different levels reached out to me by phone to talk with me, ask me about my experience, and make things right.While my plumbing leak experience wasn't good, the corporate follow-up was prompt, thorough, and positive. Perhaps I will use Roto-Rooter's services in the future.Original Review (July 29, 2022):Worked with Rotor-Rooter to diagnose a pipe leak. The technician didn't seem knowledgeable, going so far as to suggest fixes that would only mask the leak—causing more damage in the long term without fixing them. Technician was unable to find the leak.Additionally, technician didn't come within the 6-hour window stated. Technician arrived hours after the end of that window, meaning I'd lost an entire day waiting for them to arrive. If I'd known how tardy and ineffective Rotor-Rooter was, I would have hired another company to come instead.Rotor-Rooter charges a lot for emergency pipe diagnoses. I recommend not working with them, as you might pay an arm and a leg for late work that ultimately doesn't solve your problem.I worked with another local company later to successfully find the source of the leak.
