"The cracked pipe ended up being between the first and second floor where drain pipes from the upstairs bathrooms came together in a Y-joint. The house is 45 years old and these old plastic pipes eventually crack from flexing, etc. which is exactly what had happened. Fred had to cut 10 inch wide strips in the drywall in the kitchen and bathrooms walls and ceilings to get at the area to replace the leak. He added some rubber sleeves to the new Y-joints to allow for some flexing of the house so this would not happen in the future. When all was done, the repair was $2300 and I had to hire a drywall contractor for another $500 to fix the drywall, but Fred was upfront about the price, the extent of the damage that would have to be done for the repair, and the need to fix the drywall after he left. While it really stinks to have to cough up almost $3K to for a leaking pipe, that's the cost of owning a home build in the 1970's with cheap materials and I was very impressed with the work done by Fred and his same day responsiveness. At least the leak was noticed right away so we did not have any water or mold damage to deal with."

"Mr. Rema arrived on time Sunday morning to update my water heater. He installed an expansion tank, duct work and replacing the piping to the thermostat on the water heater. He did an excellent job and took his time. Mr. Rema also went to the local hardware store twice to pick up the material that was needed. The only reason I didn't give him an A was because he quoted me a price at the beginning and then went done on the price and then tried to go back up to the original quoted price. After talking with him he decided to keep the price at the lower amount that he quoted."

"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."

"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."

"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!"

"I hired JC Flood to fix my hot water heater. They popped over for a quick appointment and our hot water heater worked for a few days before dying again. JC Flood explained the hot water needed to be replaced. They were excellent about including proposals for replacement units. Very much appreciated!"

"Had a section of my polybutylene water line change from the water heater to the main manifold. Jason, the plumber was experienced and very professional. Worked me through what he was going to do before starting the work. Replaced the pipe and made sure the issue was fixed before leaving. Took the time to give me an estimate for replacing the entire polybutylene plumbing in the house as this system is no longer recommended due to high failure rate."

"Pohlman responded quickly when my water heater leaked and quickly replaced it at a competitive rate. I asked for multiple quotes and they were one of the first to respond. I appreciate the work, although I would have preferred to know which water heater was being installed before they put it in."

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.
