"Derrick did a great job! He worked efficiently and his communication was excellent. He left the bathroom spotless, fixed the toilet issue by replacing the mechanism in the tank, and showed me what he repaired. I highly recommend Derrick and will be calling him again if I have any plumbing issues in the future! Thank you Derrick!"

"Recently used Mahon Plumbing for various plumbing needs around my house. As a new homeowner you can be skeptical on what’s behind your walls or in this case pipes. Mahon did an initial sewer line inspection and called them back to swap out toilets and install natural gas in my backyard for a grill and fire table. They were professional, honest, and extremely knowledgeable about all phases of my projects. I would recommend Mahon Plumbing for all of your plumbing needs!"

"Hello, I am requesting assistance from a licensed plumber/gas fitter for gas service restoration at my property: 1239 Maple Ave. Baltimore, MD 21227 BGE has determined that the prior gas service was abandoned and is now processing the project as a new gas service line and exterior meter installation. BGE will be meeting me on-site on Tuesday, June 9, 2026, at 9:00 AM to review and approve the proposed exterior meter location. I need a licensed plumber/gas fitter who can either attend that BGE site visit or come immediately afterward to evaluate the work required on the customer side of the gas system. The scope of work includes: - Inspecting the existing gas piping to determine whether any portion can be safely reused; - Extending, repairing, or replacing internal gas piping as needed; - Establishing the new customer-side gas connection point for the exterior BGE meter; - Pulling the required gas/plumbing permit; - Performing the required pressure test; - Coordinating the requir"

"Honest ABE Plumbing is my new favorite plumber! We needed to replace a water heater, converting it from electric to gas in order to be able to recover hot water quicker. We are on a well, which posed another issue all in it self. Abe Lazar was incredibly patient, giving me my options, explaining GPM recoveries, gave me upfront information on tankless systems, helped me look into a power anode rode....His patience was so much appreciated and his knowledge he shared extremely helpful. He priced our work out for a price that fit our budget and got us the heater we needed. We will use Honest ABE Plumbing again. Fantastic company who hears your needs and makes sure you get what you need in the end."

"We have used Doug 2 other times before, and had nothing but great experiences with him. When our pipe froze, he immediately came out to assist. And when I say immediately, I mean 11:30 PM.  We had hoped to see him in the next day or so, but he came that evening. We were more than appreciative.  The job required him to come back the next morning to complete, and he was here less than 10 hours later. We were without water for less than a day thanks to Doug.  I cant begin to tell you how professional he is, he took the time to explain why this occurred, what would prevent it in the future, and what to expect going forward.  With Doug, everything is above board, and there are no hidden costs.
