"All I needed was a replacement for a broken, rusted toilet flange that was set in cast iron. The technician was very professional, and the quality of the work was excellent—I could never have done it myself. I gave 4 stars instead of 5 only because of the cost ($650). To be fair, I didn’t get any other estimates, but it did seem a bit expensive for a job that took only one hour."

Customers say: Quick response

"Cody and his crew were amazing-- we had a complicated issue that required multiple visits and coordination with the city's engineers. Cody was professional, knowledgeable, and as dedicated to getting the job done right as if it had been his own home. His quotes were accurate and competitive, he and his crew were on time (and often stayed late!) and kept the work area clean and safe. We will never call anyone else!"

"Brian Provencher and son were prompt, courteous, efficient, and reasonably priced. I had a pipe burst on a Sunday night that required me to shut off water to the house. I put in a call to Provencher Plumbing & Heating Monday morning. They had a job scheduled for that day but took the time to come to my home to assess the problem, and then were willing to reschedule a less urgent job they had the next day so as to come fix my pipe first thing in the morning. They arrived early as promised and worked efficiently to get things fixed, a job which required cutting access openings in the walls and tracing a leak from the basement to the second floor. They were careful to do minimum cutting and in the least obtrusive locations, showed me the problem segment of pipe, and were good to explain everything to me as they went along. Both father's and son's manners were courteous and professional. I have already recommended them to a neighbor."

FAQs for water main install, replace or repair projects in Derry, NH

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.
