Leak Detection in Central Maryland

Jordan was amazing with his expertise, communication and professionalism. He worked diligently on the sewer cleanup and explained everything patiently throughout the process. He did a good job by limiting the amount of digging and cleaned up well after him. Would highly recommend.

Prime plumbing in Baltimore, prompt, efficient and reasonable price.

It's taken me a while to write a review with two young kids- but i wanted to make sure i shared what a wonderful experience we had using Prime Plumbing. We had a sewer line back up in our basement (yuck) and i had multiple plumbers come out and give quotes on digging up and replacing our old copper sewer line with pvc. Tim impressed me from day 1 and stood out amongst the others with his confidence and expertise in what our options were, what to expect from the whole process, etc. They dug up our lawn (8 ft deep, approx 40 ft long) and i am so happy with how they managed to put it all back together. I can't take a current picture of it now because our yard is covered with snow, but 2 months later you'd hardly be able to tell we had a trench dug up. We were quoted around the same price by another company who said they would need to tear out our retaining brick wall and also said they'd leave piles of dirt, and that the grass seed/hay would cost extra!! Also, Prime managed to get this all done in 1 day. Not to mention, we got to keep our beautiful maple tree! This is the only tree in our yard and our kids love swinging on it so while i was ready to give it up if need be, i was going to be a little devastated. Only a few days after my initial consultation with Tim, we had a brand new sewer line! We are so happy we found a good, reliable & trustworthy company to make us feel better about forking over a pretty penny on a hidden (but very crucial) repair. Thank you Prime Plumbing!

Great work! Very nice service; fixed our water heater issue and had us back up and running in no time. The service provided by Ernie and Hayleigh was very professional and courteous.

[UPDATE: RESOLVED] I'm updating this review to reflect that Prime Plumbing has owned up to the situation and made it right. Once my new toilet arrived, they returned and completed the installation at no additional cost to me. The 5-stars are for Ernie and Hailey who handled the final install, and they were a complete 180 from my previous experience. They were awesome, professional, and sociable. You could tell they actually enjoy their work and take pride in it. They got the job done right. While the road to get here was frustrating, I appreciate the company standing by their work and sending the right team to finish the job. [OLD REVIEW] I hired Prime Plumbing to fix a toilet leak, and after 4 visits and hundreds of dollars, I had to do their work for them. Here is the timeline of negligence: March 27, 2025 (Invoice #90891): I paid an $89 trip fee to have a technician come out. He did a visual glance without even lifting the toilet and told me "nothing was wrong." The leak continued. Nov 1, 2025 (Invoice #97073): I paid $634.56 for a "Toilet Pull and Reset" (Service Code TUR-110). The invoice states they would "prepare the mounting system." They claimed the issue was a decayed wax seal (after initially guessing "condensation"). They did not inspect the toilet for cracks, but they didn't miss the opportunity to try and upsell me a new water heater. The leak continued. Nov 24, 2025 (Return Call): When they came back, the technician tried to blame "condensation" again and claimed "these electric toilets aren't reliable", again making excuses. He replaced the wax seal again without inspecting the toilet. Nov 30, 2025: The leak returned. Before booking them again, I spent 1.5 hours doing what they should've done. I replicated the leak and reached behind the toilet to feel the failure point. I felt the wax ring and—crucially—I felt plastic obstructing the seal. Dec 1, 2025 (Invoice #97936 Return Call): The tech arrived, and I told him what I found. He told me, "That's impossible... Show me how you did it. Show me this magic." I had to literally get on the floor and prove it to him. I ABSOLUTELY should not have had to do his job for him. He then complained about how he "can't keep coming out here" and is "losing money." Completely unprofessional. He finally pulls the toilet up, actually inspects it, and finds a crack. He sounded gleeful showing it to me, acting like this vindicated his misdiagnosis. He then told me I need to pay a third time to have a new toilet installed. THE REALITY: Did he inspect it the first time? If he did and saw no crack, then he caused the crack by mishandling the toilet. Did he not inspect it? Then the crack was there the whole time, and due to his incompetence, he misdiagnosed the issue for months while taking my money. I paid premium pricing for a professional diagnosis and fix. Instead, I got laziness in March, incompetence in November, disrespect in December, and an issue that wasn't fixed. Now they want more money to fix the issue they likely caused. Avoid this company unless you want to do the plumbing yourself after paying the bill. When my new toilet arrives, I will be reaching out to them to complete the install of the toilet at no additional cost to myself (I am not asking for a refund on the cost of a toilet, just want them to install it properly.) Otherwise, this is definitely going to be a complaint to the MHIC.
