"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."

"This plumber was referred by Home Depot. He was the third person that returned a quote. He offered the best quote. We scheduled a convenient time and he arrived on time. He fully explained the work that needed to be done in a comprehensive manner. The work was done in a timely manner and left the area clean. Payment was within the initial quote. I would hire this plumber again."

"Dan and his team were both efficient and knowledgeable. They installed a french drain sump pump and made repairs to our footings at our residence three years ago and not a drop of water since then! Thats why we recommended them for the work we recently did at our church. The crew installed a complete system with two sumps and pumps in two days! From start to finish they did an outstanding job at competitive prices using quality materials. The clean up was amazing as well! Except for the new concrete, you would never know all of the work that was involved! I highly recommend Dan and the Basement Guruâ s for all of your water infiltration/foundation needs!!! You wont be disappointed!!!"

"The customer service call prior to the appointment was professional. The plumber arrived on time. He provided overall inspection on what was needed. The problem was their outrageous prices. They are set in a menu-style form, which is fine, but were steep in general. I had no choice, but to hire someone else."

"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."

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.
