"This company is nothing other than excellent. A bit pricey, but you only get what you play for - and I got plenty. On Saturday afternoon, I found out that I needed a complete sewer line replacement. By late Sunday afternoon, I had one! The crew had to dig down about 10 feet to remove the broken line and then had to tunnel under my patio to get to the cast iron pipe in order to connect the new line. After the installation, the dirt was replaced, the area was seeded and covered with straw, and the sidewalks and parking lot were sprayed clean. Every single guy in the crew was friendly and knowledgeable. Special thanks to Gregg, Chris and Mike. I have recommended Mahon to friends and family and have already scheduled another job. If you need a good plumber, whether for something major or minor, I highly recommend Mahon Plumbing."

"They replaced my leaking Poly water line from the street to the house with a new copper line. They tried to pull the new line through but were unsuccessful so they eventually had to trench through my yard to install the new copper line. In order to do this, they did have to cut through my concrete driveway which I had to get patched. After some adjustments were made with the new water pressure valve the system works great."

"The entire team did a great job. They were responsive and worked to my timeline. Main supply line replacement is not pleasant but they made the best of a difficult situation."

"Our experience was a positive one. We were thinking we needed to replace the sewer line and Abbott quickly diagnosed the problem as a clogged up line vs a job that needed the sewer line replaced. Very happy with their knowledge and customer service."

"I had a sewer backup in my basement. Used Angi’s list and gave RTillery, Alex, a call. They were fantastic - great estimate, responsive, professional, courteous, quick in all their responses, the list goes on. I started with replacing the inside cast iron pipe. Alex even added a clean out. He and his crew were prompt, always polite and professional. They didn’t seem to mind my popping in to watch. The line was replaced in a day and a half w/ minimal water outage. After going back and forth I decided to replace the outside pipes. Alex provided several options. Other estimates would dig up the yard, sidewalk and driveway, replace the cast iron and terra cotta, but no cement work. RTillery slid the new PVC inside the terra cotta which was cheaper and less to dig up and they replaced the sidewalk! Only one other company offered to sleeve the PVC and it cost more! RTillery even came back to fix an issue they noticed doing their final checks. Wow! Can’t recommend these guys enough!"

"The kitchen drain was snaked but a vent and a clean out needed to be installed. The company that did my kitchen remodel did not do a good job. After they installed a vent and clean-out the line was snaked again. A few days later I noticed Water in another part of the house. It was a leak in the main stack. It seemed that the cast iron pipe had rusted and with the snaking, it developed a hole. My house was built in the 1920?s and this was the original stack. These plumbers were able to do it all and at a great price. Much, much less than I would have paid through some of the other plumbing companies. I will use these guys again and again. Everything was explained and I saw the problems with the pipes. I was impressed that they showed up when they said they would and if they were running a little late they would call. They are able to do the job quickly and effectively. They are and A+ in my book.

"Everything went smoothly. I had called the week prior to check on getting an appointment to get a new hot water heater installed and fix a problem toilet. The guys at Hamilton were very responsive, took my call and were able to schedule an appointment 1st thing in the morning early the following week. Service was prompt and efficiently done. I would use Hamilton Plumbing again."

"James did multiple jobs for me after diagnosing the actual problem. Correcting the issue required james to replace part of an old pipe which could only be accessed through a ceiling. James not only fixed the plumbing issue, he completed the carpentry work and repaired the ceiling. He also replaced my shower floor and the tiles surrounding it. James also replaced faucets on my utility sink. James is exceptionally knowledgeable, professional, and a master of his craft. I highly recommend hiring him for your plumbing needs and wants."

"As it turned out to be an A/C problem Rob didn't perform the service otherwise I'd have hired him for the repair on the spot.  He explained our issue and assured me that there wouldn't be any worse water in our basement while we were away which relieved my concern.  Rob also answered questions I had about our hot water heater.  He was nice and knowledgeable.  We'll definitely call him with our next plumbing project or problem.

FAQs for water main install, replace or repair projects in Maryland-line, 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.
