"They did an excellent job. It required 5 trips because we had multiple problems. We had a sewer back up and they came right away. They were extremely professional, reliable courteous, and answered all my questions. I would highly recommend them and I would definitely hire them again."

"I was not impressed that he repaired my broken pipe inside the wall without opening up the access panel to check for leaks in the wall. I bowed to his expertise."

"Mitchell was very professional and great at the work he’s done on my 2 homes. I’ve had 2 bathroom remodels. Funace and hot water heater replaced. Put an expansion water tank on one of my homes. Hooked up my water for my new refrigerator and dishwasher. Have not had any issues with his work. Highly recommend."

"It was a pleasure to work with this company! The plumber that came out to do the plumbing on our entire kitchen remodel was always on time, had a great work ethic, always had a smile on, and always asked what we wanted to do about specifics when there were different ways we could do things. (For instance if we wanted our kitchen sink faucet to match our outlet covers, they even asked us if we would be installing a dishwasher and a garbage disposal so that the pipe sizing was correct because the contractor we had hired would show up when he felt like it) The small details they covered are what made it a very pleasant experience. Any time we had questions they were willing to answer. They went above and beyond what other plumbing companies have done for us in the past! We are recommending them to friends and family, and anyone else who needs any plumbing work done! We are about to book them to do our bathroom remodel as well!"

"Well, the first time the replacement was ordered it was the wrong one, which of course, delayed the installation a week. When it was finally installed I had to pay an additional $850 for code upgrades. This I was not informed of by Home Shield. Then we noticed that there was water on the garage floor and found that the pipe coming in from the wall was leaking at the wall so had to call the plumbing company back out to fix it. They first tried to say it was not their fault but since there wasn't a leak before they installed they did fix it. I have used Home Shield a few times before and never had a problem. Some of the companies they use are not the best so you have to research them before you commit. I have found HS service to be good if you do your homework. At the end of the day I was without hot water for almost 3 weeks but it was do to the plumbing company they sent out."

FAQs for sewer main install, replace or repair projects in Sandown, NH

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.
