"I had a plumbing issue that I thought would turn into a major headache, but Mahon Plumbing made the whole process smooth and stress-free. They arrived on time, quickly diagnosed the problem, and had it fixed before I could even make a second cup of coffee. They were professional, knowledgeable, and even gave me a few tips to avoid future issues. The pricing was fair, and there were no surprises on the bill—just great service from start to finish. If you need a plumber who knows what they’re doing and won’t leave you with a mess, I highly recommend Mahon Plumbing. I’ll definitely call them again for any future plumbing needs!"

"They did plumbing services. It was basically the toilet tune-up that they were supposed to do. They fixed it on Friday but on Sunday, it did not work again. Took one more week to get out here and they still have to come back to replace the toilet. At the end of it all, that didn't happen."

"Five Star Bath Solutions did an amazing job on our master bathroom! Their customer service from beginning to end was top notch-- couldn't have asked for a better experience. My wife and I had tons of questions and from the salesman to the install manager, to Brittny in the office, to Steve the installer... they took the time to answer everything, and it was perfect. Our Master bathroom looks like our dream bathroom now. I highly recommend Five Star and will be using them again for our guest bath!"

Customers say: Quality work

"Robby did an excellent job with our master bathroom, and we were completely satisfied with the work; the ceramic tile work in the shower is beautiful. He did the extensive demolition work quickly and efficiently. His workmanship is excellent and the subcontractors for the floor, plumbing and shower door were top-notch. He is reliable and efficient when scheduling work to be done; easy to work with and very creative. Would definitely recommend Keedysville Construction."

FAQs for plumbing projects in Frederick, MD

It depends on the severity of the leak. Minor leaks may not require immediate attention and can be scheduled during regular business hours. However, if the leak is causing significant water damage or you can't control the flow of water, it's best to call an emergency plumber right away. Addressing serious leaks promptly can prevent structural damage and mold growth, potentially saving you money on extensive repairs later.

A journeyperson plumber is a licensed professional with a state-issued permit who installs and repairs piping for water and heating systems under the supervision of a master plumber. They have completed extensive training and amassed significant experience leading teams, drafting blueprints, and designing comprehensive plumbing installations. Their proven expertise ensures that they can handle both routine repairs and complex projects with precision.
