"First, they responded by phone within an hour of my requesting a quote through Angie's. The dispatcher, Bona, was friendly and knowledgeable, and she said that Fred could come out the next morning between 9-10am, which he did. Fred did a great job. He's very thorough and personable. He explained everything that he was going to do and the reasons for doing each thing, and then went over each item when he was finished. I was very impressed and definitely will use them again for future plumbing needs."

"They came on time and completed a task that other plumbers wouldn't do. The task was straightforward enough but required simple dismantlement of tight space. This company will now be the first I go to for any new plumbing work. Their price was also fair. Thanks!"

"The technician from Prime Plumbing did a superb job of replacing copper water lines on my yacht. He arrived promptly and was VERY professional! He took the time to analyze the issues, offered an in-depth explanation of the job scope and noted safety features like backflow preventers now available, since she is an older yacht. The technician had to work in a tight space as well. Very methodical, careful, and thorough. Our water system works like NEW again! I would highly recommend Prime Plumbing for any plumbing repairs at our home or yacht!"

FAQs for plumbing projects in Gaithersburg, 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.
