"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!"

"Remedy Plumbing was GREAT!!! They came to my house on Sunday without an extra charge for the weekend call. He was extremely knowledgeable. My sump pump had gone bad. He was prompt & very efficient. Decided to have him fix a bathroom problem while he was here. Highly recommend if you have a plumbing problem, call Remedy Plumbing & Drain Co."

"I hired a plumber through HomeAdvisor using prepay but I would not recommend this service. The contractor left a leaky pipe that caused water coming up through carpet. I had to purchase a wet vacuum to dry out the carpet. I had to contact HomeAdvisor again and hired Dave the Plumber, LLC who had to redo the installation done previously. Dave the Plumber replaced all the piping and outside spigot because of a water leak the previous contractor left. Thank you Dave the Plumber for being a professional and a job well done."

"Had sewer line break..was very impressed with personnel, Mr. Woodrow was very professional in doing a great job in a messy and tricky situation with my sewer line/old home. He took time to figure out the problem with me having no additional help.. never got frustrated - took time of understanding the complications of my old homeâ  s layout.. so yes Iâ  m impressed with my new plumber.. why wouldnâ  t I - proved me wrong..but not really - he told me it was going to be all good!!!.and my pockets arenâ  t hurting too much either-definitely love that!"

"Josh, the representative from Basement Gurus was outstanding! We had experienced a water issue in our finished basement. Josh thoroughly examined the interior and exterior of the home and determined that the leak might be plumbing related. Josh could have very easily exploited our ignorance and suggested a solution purely beneficial to his company that may not have addressed the underlying cause of the problem. Instead, he demonstrated his integrity by realistically assessing the situation even if it would jeopardize the sale. This is commendable particularly in this era where cutthroat business practices are commonplace. I highly recommend Basement Gurus. They are fortunate to have an employee like Josh who exhibits concern for the customer at such a high level."

"Mike did the troubleshooting to identify the fault while explaining to me what he was observing, then isolated the problem down to the well pump (which I already suspected). I also watched Mike do a meticulous job in shrink-tubing the connections, wrapping it all in electrical tape, and inspecting the entire length of electrical conductor TWICE. What Mike did NOT do was try to sell me an entire GrundFos system when all I needed was the pump. Yes, I had a past plumber contractor try to load up my bill unnecessarily. Mike of Atlantic Blue did a fine job."

"Once and done waterproofing helped me out with a small annoying leak Iâ  ve had around a pipe. The owner called me right away, came out the next day for an estimate, and fixed the leak the day after. His crew is friendly and courteous and hard working. Explained every step they weâ  re doing. Did such a great job, I had the bury some drain pipes and install a rain water reservoir. Very reasonable pricing and veteranâ  s discount."

FAQs for plumbing projects in Unionville, MD

Schedule a plumbing inspection every one to two years to ensure your system is in good working order. Regular inspections can help you catch minor issues before they become costly problems, like major water damage repairs. You should also consider a plumbing inspection when buying or selling a home or if you notice signs of a plumbing issue. Staying proactive with maintenance can save you money and stress in the long run.

A plumbing inspection for a standard one-story to two-story home takes between two and three hours. For larger residences, historic homes, or rental complexes, a complete inspection requires a full-day commitment of eight hours. However, this does not account for any necessary repairs that your plumber might find, so it’s best to set aside additional time during the inspection in case an unexpected repair comes up.

When built with quality materials, your plumbing system endures for decades. CPVC, brass, iron, and steel provide reliable service for 50 to 70 years, while copper extends durability up to 100 years, and PEX maintains performance for 80 to 100 years. Maintaining this system with regular inspections and prompt repairs guarantees long-term efficiency.

You should repipe your home when your plumbing exceeds its expected lifespan or uses hazardous materials like lead, polybutylene, or galvanized steel. Persistent leaks, corrosion, and compromised water quality signal that your existing piping no longer meets safety standards. Repiping eliminates potential health risks and prevents extensive water damage.
