"OK, so Mr. Frank was very professional. All his team was very professional, very polite. They were on time and they went far and beyond of what they were supposed to do and did not charge me more than what they said, so I am very very very satisfied with the work that Frank did, and I wanted to thank him team for being so wonderful and such a great People, we don’t get that anymore in America, but he definitely gave me that. And I’m so happy that I hired him. I had five different people that I got proposals from, and I called all of them multiple times to check on things. And definitely Frank. He definitely made this right. So if anybody needs a Plumber, that’s the guy needs to be hired once again. Thank you very much for all your services. And I recommend Frank to anyone that needs plumbing work done Thank You,"

"The technician, Marvin, could not have been more professional, knowledgeable and efficient. The main issue we wished to resolve was changing the shower. Marvin communicated the process involved, project pricing and returned on the second day with necessary parts to complete the job. The entire experience working with him was seamless and was a great way to start 2026!"

"Initial rep was great and informative. Felt comfortable with initial sale. Hardly had any contact from customer service except for the payments. There were several delays that we were not informed about unless we called to ask. Took 7 months before they showed up to begin project. Only 1 person was sent to build steps. Took a week. Hard worked, hardly took a break. Had to call again to see when they would come to pour patio. Never knew when they were coming, they just showed up. Hardly spoke with the homeowners. Inspection paperwork was just left on porch. Additional paperwork that is "required by the County" had to be completed by homeowner and taken to Court house to be notarized and filed and also provide a copy back to Long Fence. Time sensitive materials which added to homeowners to-do list. Gave this contract to LF on the surface of their history and appearance of a 'good local company' but should have stayed with original contactors in VA. Puddle of water forms when it rains"

FAQs for sewer main install, replace or repair projects in Washington DC, DC

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.
