"DO NOT JOIN THE JSP Home Care Club! In 2024 they began billing me twice every month for my membership in the Home Care Club; this continued into 2025. When I realized this a few months later, I contacted them and spoke to Robin who promised to refund the money--they owed me over $300--he did not refund all of it. Through several back and forths (this has been going on since August 2025) I have gotten a little more back but not the entire amount. Had to get the NYS Division of Consumer Affairs involved. My advocate managed to get a few more bucks out of them. I disputed the charges with my bank; JSP forked over a bit more, but still not all of it.They owe me $135. They do not respond in a timely fashion, if at all. They have a bot taking calls, so speaking with an actual human being is virtually impossible. I did receive one unsigned email from someone telling me to "check my records". I have informed them that I will be taking them to court. "

FAQs for sewer main install, replace or repair projects in Cornwall, NY

When installing a sewer line, you should consider extra costs like tree removal, driveway repairs, or patio resurfacing. Hiring a professional plumber is essential, and you may need additional specialists if landscaping or heavy excavation is involved. Addressing these potential extras up front helps ensure accurate budgeting and prevents sudden cost overruns.

To calculate the length of sewer piping you need, measure the distance from your house to the main sewer line, adding the depth of the city main to this distance. Be sure to account for any obstacles like tree roots or utility lines that may require additional piping.

City sewer lines are installed at a lower elevation to prevent unwanted backflow and water damage. This lower positioning ensures enhanced performance and long-term safety, meeting all technical and safety standards.

With trenchless methods, a plumber inserts a smaller pipe within the existing plumbing, avoiding full excavation. It can be more cost-effective and less disruptive than traditional methods, but it's not suitable for all homes.

Yes, you must secure permission from your local water authority before connecting to a public sewer line. This approval ensures your connection meets all regulatory requirements.

Sewer lines are buried between 18 inches and 8 feet deep, with most systems placed between 18 and 30 inches. In colder regions, pipes are set deeper to remain below the frost line.
