"They were friendly and professional. They Communicated well at every step of the project. Matt Kelly was particularly responsive and helpful. For a job that could result in a great deal of disruption and destruction of landscaping and foliage, their method of piping was truly impressive. Pulling the new pipe in with the extraction of the old pipe was amazing. This resulted in a minimum of excavation and invasion of the ground features. I would highly recommend Trenchless Piping Solutions to anyone needing this service."

We have extensive experience working with both residential and commercial projects, and we pride ourselves on completing every job with professionalism, attention to detail, and full compliance with DEP and DOT regulations. We don't work inside the building. Our services include: Water and sewer line installations and upgrades. Emergency water/sewer repairs. Full DEP and DOT permit handling Street asphalt and sidewalk excavation and restoration after service completion. We’re currently seeking to partner with developers, general contractors, engineers, and property managers who require reliable subcontractors for infrastructure-related work.

"I had a broken sewer line. Hired All City Water and Sewer. Val came and explained the work entailed for a line repair and to install a new sewer line. No hard-sell to replace the whole line (unlike other sewer co.s). He gave me a price quote for both the repair and the replacement. I found Val to be knowledgeable & relaxed, and felt confident in All City's ability to do a good job. There were problems with my sewer over the years so I decided to replace it. All City crew showed up as scheduled, were pleasant & polite, kept me informed of when the water would be turned off and back on. Very organized. The job was done in a timely fashion, very neatly, and without being intrusive. I couldn't have asked for a better experience All City was a pleasure to work with. On top of that they gave me a great price for the job. I received two other estimates after I hired All City and both were higher. Highly recommend using All City Water and Sewer. They did a great job at a good price."

FAQs for sewer main install, replace or repair projects in Larchmont, 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.
