"About 2 months ago we had the techs from Diffley Drain Service out. At that time they ran a snake through the drain and pulled out a small root 75 feet down the line which at the time seemed to clear the backup which was manifesting itself in our basement utility sink. Thirty-three days later the problem manifested itself again and to their credit even though it was three days over the warranty period they came back out without any fuss. They snaked the drain again this time going out 105 feet without clearing anything. Now here is where things get a bit dodgy, rather than add a 2nd reel of cable onto the snake (or really even mentioning it) to enable them to snake further the tech tells my wife that they will need to install an external access point in the yard so they can snake further down the line and that will cost $3000. We say we'll think about it and explore other options. Once we watched some videos and educated ourselves about the matter we ended up hiring a different drain service. The new company we hired used 2 spools of snake to be able to go further down the line and cleared a bunch of roots 140 feet down the line. BUYER BEWARE with Diffley Drain Service they seem to only give you part of the story in order to seem credible. I will say that Diffley comes quickly and promptly which when you have sewer backup issues is a positive and they are initially reasonably priced but educate yourself about your problem or you will get taken advantage of."

"I called Scott's plumbing on a tuesday night, told him what was happening and he bought the water heater the next day (wednesday) and he was at my house at 7:20a.m. on thursday and was done at 8:15 in time for me to get to work on time. I did explain to him I had to be in work by 9:30am and he accomodated me. He did excellent work in timely manor and left no mess. I was really happy with the price because I did call the other 2 companies suggested by this website and he was the best in price also. I would highly recommend Scott's plumbing."

"I had a leak in my main septic line coming into my house. Kyle and his men came when committed, dealt with a few surprises and fixed the problem. They were expensive but it was worth it. I plan on using them again next month ."

"Everything went wonderfully with this company.  They were very professional, listened to exactly what my problem was, and explained to me how they were going to diagnose the problem and/or solve it before doing any actual work.  Once they started, the team (three people came) worked together like a well-oiled machine.  One was in the room with diagnostics, one was at the fuse box looking for possible problems there, and the third went into the crawlspace beneath our house to look at the physical wiring.  Once the problem was found (there was a faulty wire beneath the house that had come loose from the junction box), it was fixed and tested within minutes and another full diagnostic was done to make sure there were no other possible issues.  They cleaned up after themselves very neatly.  They also replaced the light switch with a dimmer switch at no extra cost!  Well within my budget, and came in even lower than their original (FREE) estimate!  I would highly recommend this company to anyone in the Bergen County area.

"Wayne and his team did a great job from start to finish. It was a really big project going from cesspool to septic. He handled everything from the blueprint planner, DEM, licenses from town, down to the installation. At the end showed me the set up and explained to me the maintanence of the tank. Felt very comfortable throughout with his ability and knowledge would defintely use and recommend again."

"Have never had this quality of service and expertise in any home repair. I thought that I had to replace my heating/hot water boiler but after a thorough review/examination of my present boiler system Eddie assured me that after some repairs to my present system it would be as good as new. I called Eddie on a saturday and he responded that same afternoon and provided an estimate of the work that was needed. By monday evening all the repairs and work had been finished. Eddie saved me about $5000 because of his work on my present boiler and honest opinion that a new system was not needed. Eddie and his crew were courteous, knowledgable and very timely in getting the work done. Eddie was very thorough in explaining what he was going to do and why he was doing it. It was such a pleasure to find a contractor that had the knowledge and ability to resolve my problems. I would highly recommend him to anyone that had plumbing and or heating issues."

FAQs for sewer main install, replace or repair projects in Harmony, RI

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.
