"Derrick did a great job! He worked efficiently and his communication was excellent. He left the bathroom spotless, fixed the toilet issue by replacing the mechanism in the tank, and showed me what he repaired. I highly recommend Derrick and will be calling him again if I have any plumbing issues in the future! Thank you Derrick!"

"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!"

"We experienced a leaky shower and consequently scheduled an appointment with Len the Plumber for Saturday. We devoted the entire day to this matter, only to receive an automated call around 5 PM notifying us that the plumber would not be able to attend. As a direct result, we had to take a day off work and subsequently rescheduled the appointment. On that day, the initial plumber arrived and found the gasket faulty. He advised us to procure the part independently and provided a total cost estimate of $470, which included an $80 discount for arranging the repair after the necessary parts were obtained. We ordered the required components and set up another appointment. The second plumber replaced the gasket and subsequently charged us an additional $310 beyond the original estimate. My husband, unaware of this, settled the payment. To this day, with multiple phone calls to them, nobody ever called us back or refunded us the extra charge ! Can you trust a company like this !!!"

"Had a sewer line break and the toilet kept backing up. They worked out a payment plan Im so grateful for that as a new home owner I was not prepared to pay so much at one time. They took about three days and they work when it just snowed. So far so good!"

FAQs for water main install, replace or repair projects in Baltimore, MD

If you notice puddles or standing water in your yard, a sudden drop in water pressure, cracks forming in your foundation, frequent clogs in your plumbing fixtures, or water that looks or smells unusual, you might have a leak in your main water line. These signs mean it's time to call a professional to evaluate the issue and prevent further damage.

A professional water main inspection is a comprehensive evaluation performed by a licensed plumber who checks every section of your plumbing system. The inspection costs $165 and uses advanced diagnostic techniques to identify hidden leaks or wear. This service clarifies the exact condition of your water main, enabling precise repairs that prevent future damage and ensure the overall health of your plumbing system.

Protect your water main by scheduling a cleaning and inspection every two to five years. The average cost of a sewer line cleaning is $400. It’s also important to never dig in your yard without first calling the dig line (811) to ensure you don't accidentally hit the water or sewer lines. Watch for soil erosion, low water pressure, or wet spots in your yard, and take immediate action if you suspect a leak. Remember, the longer you leave it, the worse the problem gets and the more costly it is to fix.

When properly maintained, your water main is engineered to remain functional for 50 years or longer. A durable water service in excellent condition should consistently perform without major issues for half a century. In contrast, metal pipes exposed to acidic soil corrode faster, whereas modern plastic pipes resist corrosion and function for decades beyond metal alternatives. Regular maintenance and inspections are essential for confirming your system’s longevity.

No, homeowners insurance does not cover the cost to repair a water main. Insurers fund only sudden, unforeseen events like a burst pipe and exclude gradual issues or normal wear and tear. Damage resulting from leaks, such as mold remediation or property claims, is not covered. It is essential to contact your insurance provider immediately to confirm your policy’s details and any potential adjustments needed.
