"Recently used Mahon Plumbing for various plumbing needs around my house. As a new homeowner you can be skeptical on what’s behind your walls or in this case pipes. Mahon did an initial sewer line inspection and called them back to swap out toilets and install natural gas in my backyard for a grill and fire table. They were professional, honest, and extremely knowledgeable about all phases of my projects. I would recommend Mahon Plumbing for all of your plumbing needs!"

"Great service from this company. Arrived on time, super clear and thoughtful, quoted me the price for enough demo to identify the leak source. It was difficult to figure out but he stuck with it until we found it, and it's not a plumbing problem so their work ended there. I would definitely hire again, and appreciated that they were able to come within a few hours"

"I would recommend Remedy P&D to anyone needing a plumber. They were fast to respond and schedule an appointment for a free estimate. The plumber arrived on time and was dressed in a professional company uniform. The plumber also recommended a quick cost saving option for fixing my upstairs bathroom drain. Instead of trying to make a quick buck by over charging me on a simple fix he advised me to save the cost and do his recommendation."

"Prime Plumbing provided excellent customers service from the beginning to the end. Rob was very thorough when he came out to provide estimate, financing options and gave good explanation of what was needed to replace my direct vent hot water tank for my condo. Rob was also the one who installed the hot water tank and did an excellent job. Direct vent hot water tanks are much more expensive than your standard hot water tank, so it was pricey. I initially found Prime Plumbing on Angie's list and I would recommend them for your plumbing needs. I'm a single female in my early 60's. I did end up using my own financing because their finance company interest rates were way too high for someone with excellent credit. Do rate comparison first."

"The plumber was a forward thinker and his solution to the problems was outstanding. I don't remember his name but he is an excellent plumber. I will call on them for all future plumbing jobs and ask for him by name (which I will know by then). Jon May, Gaithersburg, MD"

Plumbing FAQs, answered by experts

Older Severn homes contain outdated materials like galvanized steel, cast iron, or polybutylene piping that require complete replacement. Properties transitioning between private septic and public sewer systems face complicated connection requirements. Crawl spaces make plumbing difficult to access and highly vulnerable to freezing. Additionally, small lots and proximity to wetlands restrict where you place new septic tanks or drainage fields.

Helpful?

Prepare for moderately hard MD water by keeping descaling supplies on hand to clear mineral buildup from your plumbing fixtures. Because winters bring freezing temperatures, stock up on pipe insulation for unconditioned spaces and know exactly where your main shutoff valve is located. Keep a functional sump pump ready to handle heavy rainfall. Retain all septic diagrams and well records for quick reference during emergencies.

Helpful?

Start by confirming your water source, as Severn properties use either public utilities or private wells and septic systems. Check if your home falls within the Chesapeake Bay Critical Area, which requires additional reviews for exterior plumbing. You must also account for clay-heavy soil that complicates excavation and underground pipe stability. Finally, review your HOA guidelines for any restrictions on visible infrastructure changes before starting work.

Helpful?

Reject any quote that omits required permits for new installations or modifications, as unpermitted work creates insurance and inspection issues. Verify that the contractor holds the proper state-level master license for standard plumbing work in MD. Watch out for general contractors quoting septic system repairs or well drilling without possessing the specific separate credentials required for those specialized systems.

Helpful?

Treat sewage backups, failing well pressure tanks, and burst pipes during freezing Severn winters as immediate emergencies to prevent severe property damage and health hazards. Address water service line leaks right away. Schedule routine plumbing tasks like flushing water heaters, fixing slow drains, or replacing dripping faucets for later. Submit permits for non-emergency fixture upgrades during the fall to avoid peak spring delays.
