"Our home is about 9 years old and we were quite shocked to have a leak in our main water supply line coming from the street to our home. We contacted several plumbers and listened to their approach as to how they were going to determine where the leak was coming from and whether they were going to repair a section or replace the entire water supply line. After meeting with the different plumbing contractors, we learned different methods of running a new water main line since it appeared that we would need it. We received new pieces of information from each proposal. We did not like living without water, however; since it was a big financial commitment, we did not want to be pressured or feel rushed into making a quick decision. On Saturday evening we sent an email requesting a quote from Mahon Plumbing and much to our surprise, we received a call just minutes after the email was sent. An appointment was made for the next day (Sunday). Immediately after meeting Greg, the owner of Mahon Plumbing, we knew his approach was the right course of action. With 100% confidence, he knew we just needed a repair, NOT a replacement of the entire main water line. He quickly identified where the leak was originating and guaranteed that ONLY a repair was necessary thus avoiding any sidewalk, walkway, underground sprinkler system or landscaping damage. We knew he was the right person for the job. Greg was well EXPERIENCED, HONEST, UPFRONT, had INCREDIBLE INTEGRITY, AND RESPECT for protecting our home by NOT automatically approaching our project by using heavy equipment, tearing up our sidewalk, walkway, underground sprinkler system, and landscaping to make it an easier job. We hired him on the spot. We had lower estimates for the repair. Most people would have used his confidence of a repair and gone with the cheaper proposal; however, we knew that we would incur additional expenses to repair/replace our landscaping, lawn, underground sprinkler system, and walkway. In the end, if we chose the cheaper proposal, it perhaps would have cost us the same, if not more. It may have felt better to spend less upfront, but, in the long run, it was far better to hire the RIGHT person would do the RIGHT job from start to finish. It was wonderful to see our property taken care of with such pride, as if it were theirs. Our grass was restored perfectly and they even did a repair on our sprinkler line. They left our walkway, landscaping, lawn, and underground sprinkler system intact. Not only did they do a perfect job for us, they had respect for the BAY and cleaning up the debris so it wouldn’t wash into the sewer system. Sometimes you pay a little more up front, but it saves aggravation and additional unexpected expenses in the end. Separately every plumber submitted a proposal for a continuous running sump pump. Every proposal recommended that we needed to replace the sump pump. However, Mahon Plumbing suggested that it might only need to be repaired. Only the backflow valve needed to be replaced. Again, Mahon Plumbing’s approach was correct! A special thanks to everyone at Mahon Plumbing for performing perfect workmanship. If you are looking for a true professional, then Mahon Plumbing should be your first and only call. T"

"Not sure if these guys are plummers or surgeons. Team repaired a broken water service line into the house within 24 hrs. Managed to spare landscaping and dig minimally - only at the curb to make the connection. Very professional and skilled team. Best plummers we've worked with in >20 years of home ownership."

"American Home Contractors performed roof repairs for me and they were absolutely fantastic!!! We recently moved into our home. At the time of purchase, there were water stains on one of the upstairs bedroom ceilings, however, the home inspector did not note any problems with the roof. After a number of rain storms, it appeared as if the water marks were becoming darker and more prominent. After one particularly bad storm, I used a ladder to touch the ceiling and discovered that it was wet. I called a well known roofing company (not American Home Contractors) to get an estimate on repairs. After that company came out, we were advised that one of the boot seals had degraded and that we needed it replaced. (The agent who came to the house also gave us the hard sell to replace our entire roof.) I was e-mailed the repair estimate which was over $500 to replace a boot seal!! I declined to have that company perform the work on our roof and started looking for another roofing company. Enter American Home Contractors. I received a mailer from American Home Contractors which advertised repairs of boot seals for $149. I called the company to double check that the advertised cost was accurate and I was told that it was. I scheduled an appointment with them and waited to see what would happen. The day before the appointment I was provided an appointment reminder as well as the name of the technician who would be coming to the house. On the date of the appointment, I received a phone call from the tech, Paul Cox, notifying me that he was running ahead of schedule and checking to see if he could arrive at my home a bit early. Wonderful! Paul arrived early and got to work surveying the roof. He did not give me the hard sell to replace my entire roof. He was candid about issues with my roof but did not press me to undertake any additional repairs. He performed the repairs right then and there and even went above and beyond to perform some additional repairs that we did not schedule at no additional cost. Based on my experience with Paul, I felt that Paul was honest, trustworthy, hardworking and dependable. American Home Contractors will definitely be earning my business again. I cannot recommend them enough!!!"

"Vince called me back within hours of my sending him a message through Angie's List.  Even though he does not list Montgomery County as one of his service areas, he was completely willing to help us out.  In my message, I had requested the work to be done onsite but Vince explained why having him pick up the generator and take it back to his shop to work on it would make more sense.  His charge for pick-up and delivery back to us was only $34.95.
When Vince came to pick up the generator, he was on time and was able to give me a ballpark cost for the work (which turned out to be very accurate).  He said that he could get it back to us in 3-4 days but I asked if he could do it faster as there was a snow storm predicted for the next day or so.  Vince agreed to a shorter time line and ultimately got the generator back to us within 1 day!  There ended up being no snow storm but we got our generator back in working condition - along with a booklet of care instructions, a copy of our invoice, and a service history form.  A few days later we received a hand-written Thank You card in appreciation of our business.  I can't imagine how the service could have been any better.  We will use Vince for any future small engine repairs/maintenance we have and highly recommend him and his services.

"Jorge, Jorge Jr. and their crew are a VERY professional outfit. After taking several estimates from the top-rated Angie's listed contractors in my area, I decided to go with George's Painting based not only on price(his estimate was about the median of all) but based on the very friendly, responsive and knowledgeable Jorge. He came onsite to do the estimate, and made me feel very confident in his crew's ability to do the job.
He impressed me with his knowledge of the process of cleaning and staining fences and decks.  Every question I had for him, he patiently answered. His group also did some minor carpentry work--replacing damaged fence boards and 4x4 deck posts-- Both performed to perfection. Jorge also stood out by mentioning that he preferred to use premium products so the job would last.
His crew was onsite promptly when promised (8:30 meant 8:30, not sometime around 10) Each crew member was courteous and professional. They worked quickly and did an excellent job.
Any time I had to contact Jorge (as we were working on the final scope of work, etc..) he responded in a VERY timely manner.
The end product is the BEST looking back yard in my town-home area.
Thanks to all the guys at George's Painting Inc! We will be calling again when it's time to do more painting.

"Floodbusters did an excellent job sealing the water out of our basement. They installed a sump pump and drainage system which they check annually. We were very happy with their service. Employees were polite and knowledgable. We highly recommend them."

FAQs for water main install, replace or repair projects in Unionville, 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.
