"Joseph Plumbing and Drain replaced our aging (21 year old) Rheem water heater with an AO Smith Proline 50 gal model. Kap, the owner of the firm, came out to give us an on-site estimate and a detailed explanation of the work to be performed. He showed up at 9:00 am two days later to do exactly what he had promised. Of the six different proposals that we reviewed, Joseph Plumbing and Drain came out on top. They were neither the lowest nor the highest bid, but in our view, the best bid. We found Kap’s price reasonable, his knowledge comprehensive and his work thoroughly professional. We felt we got a quality water heater and expert installation at a fair price."

"Called the main number and the lady I spoke with was very pleasant and easy to work with. Was looking to have a 50 gallon hot water heater installed, 2 drains snaked and a new faucet installed. She booked my appt for the next day. Zam came to the house to provide us the quote and even offered to do half the job then and come back in a few days to do the hot water heater. He was incredibly professional and did a great job on all the work. I highly recommend them and will call them again."

"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."

"Installation was solid. The labor price was a bit high. The main concern was the materials markup. The picked up a shower stem from Lowes. Those are normally about $50. The tech said that the stem wasn't $120 but they charge them extra when they use their contractor code. That seemed weird since normally get discounts since they purchase a lot. I should have questioned it but it didn't register to me until after he had left."

"Clayton was understanding of the emergency of replacing the water service pipe since we were without water for several days. I was charged less than some of his competitors might have done. In this emergency situation he was very reasonable, he was reliable and on time and he completed the work in one day. Clayton brought a young man with him to repave the concrete sidewalk and his work was also blemish free. Clayton addressed my question and concerns in a professional manner!"

"James Matthews was the John C. Flood plumber that responded to my call for water leakage from the kitchen faucet. He quickly located the source of the water leak and repaired it quickly. The cold water supply line valve had locked up and couldn't be turned off, so James quickly replaced the old dial valve with a 1/4 turn valve (which had already been done for the supply lines for the dishwater and hot water). In and out in quick order and cleaned up all debris. Very personable, too."

"The work itself was done very well and efficiently. For a more reasonable price than other estimates. The only quibble I have was the bed of rocks around the old water line got all mixed in with the soil when the trenches were dug. And now are at the surface of my lawn. Picking them out as the soil slowly settles and exposes them. Or where the grass seed fails to germinate. Prompt replies to questions and explanations of how the work would be completed."

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