"Matthew was very quick to get back to me and get the job done right. I had a leaking toilet that was not seated correctly so it ruined the floor beneath. I had this issue fixed 3 times before. Matthew came out and replaced the flooring underneath it and now it sits correctly on the floor and no longer leaks. I would definitely have them come back if I had any other plumbing problems"

"Drainworks team has done several different jobs to my Plumbing and Well system to get them up to excellent standards. The guys were patient and had a sense of urgency wanting to get things repaired for me. I was absolutely satisfied with every job the guys completed. I had my entire Home filter system replaced, I had a leak in my Well casing repaired and also a leak in an underground main water Pipe that had sprung a leak repaired. I highly recommend Drain Works for all your plumbing needs!"

"Mike and the Plumbing Heros have been great to me! I’ve had bad experiences with many plumbers and contractors but Mike is extremely responsive, reliable, and skilled. He’s installed a backup sump pump/battery and snaked my renter’s shower. In addition, I’ve texted/called him many times with questions and he never hesitated to answer. I highly recommend!"

"For a while, I was really always it seems that anytime I needed something, I couldn't get it timely. The first they would ask, for instance, when my air conditioning went out I had them and it's well have you maintained it. The application being that if you couldn't produce maintenance records they weren't going to do it. So on air conditioner was unhappy. They shocked me . I had a recent leak inside the loft. They sent somebody out here. They really did a good job on it. They were timely. A leak within the draining system inside the wall, I was getting water damage down the wall. They sent a plumber out. He opened up the wall and replaced the piping in there and then patched the wall back up. They don't do finish work on their patch up but hey do the patch. He was a pretty sharp young man. He was responsive. He came and he needed some things. he went and got them. He came right back. That was one that I was wondering if they were even going to do caus they'd been going on for a while. It was a drainage pipe in the wall. It was a manufacturing defect that had probably leaked from some early years of the home and got progressively worse until I could hear it. Actually when I would turn on the water on a certain faucet I could hear it drip down onto a fireplace. That's how I knew what it was. They don't do the finish. You do the finish. They do the patch. The only reason I kept them was because they showed me a different face with that repair. Before it seemed like everything you wanted they had a reason not to do it."

FAQs for sewer main install, replace or repair projects in Niantic, CT

Sewer line replacement costs range from $50 to $250 per linear foot. Your replacement costs rise or fall based on material quality, installation complexity, and the specialized equipment crews need for excavation. Deeper lines cost more to access, and choosing budget-friendly PVC piping rather than premium copper also shifts the final price.

A sewer sleeve repairs cracked or damaged sections of a sewer pipe without the need for excavation. In this process, technicians insert a cured-in-place pipe (CIPP) liner, saturated with epoxy, to seal defects and restore the pipe’s integrity. This approach protects your yard, trims repair time, and adds years to your sewer system’s life—all while delivering reliable results.

Newer homes use durable PVC and ABS piping that offer smooth interiors and effective clog prevention at an affordable cost. Older homes use materials such as copper, Orangeburg, clay, cast iron, or lead, which require a licensed plumber’s inspection to confirm safety and performance. This clear distinction impacts maintenance and overall system reliability.

Red flags include persistent clogs, recurring sewage backups, and unexplained spikes in utility bills. Strong sulfur odors, bubbling drains, and visible sewage in the yard serve as unmistakable warning signs. These symptoms demand immediate professional inspection and repair to prevent further property damage and health hazards, ensuring the system operates safely.

All sewer line projects require permits because strict sanitary and biohazard regulations mandate regulatory approval. Homeowners must secure permits, incurring a specific permit fee of $200 in addition to contractor costs. A licensed professional or local building department manages the permitting process, ensuring the work complies with all legal requirements before the project begins.

A clogged sewer line is not covered by standard homeowner’s insurance policies because these policies exclude damage from regular wear, tear, and neglect. In cases of accidental damage—such as when tree roots block the line—certain policies provide coverage. Homeowners must review their policy details or consult with their insurance provider to confirm the coverage terms.
