A failing sewer line is a health hazard. Raw sewage backup exposes your family to dangerous pathogens. NYC DOH can issue violations for unaddressed sewer issues in multi-unit buildings.
Before recommending a repair, we run a video camera through the line to see exactly what's happening — root intrusion, a cracked or offset joint, a collapsed section, or just a straightforward clog. That inspection determines whether the fix is repair, trenchless replacement, or simply clearing a blockage. We don't guess or recommend a repair sight-unseen.
Not every main line issue is a sewer line repair. If a camera inspection shows the pipe itself is intact and the problem is just a blockage — grease, debris, a one-time root snag — that's drain cleaning, not repair, and it's the less expensive fix. We recommend sewer line repair only when the line itself needs it: recurring clogs despite cleaning are usually the tell.
Much of NYC's residential sewer infrastructure dates back decades, built with clay or cast-iron pipe that was standard at the time but is prone to root intrusion at joints and gradual corrosion as it ages. Older street trees, common throughout NYC neighborhoods, send roots toward any available moisture source — including a sewer line's joints — which is why root damage is such a frequent cause of sewer line failure here specifically. NYC DEP permitting applies to most sewer line replacement work; we handle the permit applications and DEP coordination as part of the job.

Traditional sewer repair means digging a trench along the length of the damaged pipe to access and replace it directly — the most straightforward method, but the most disruptive to a yard, driveway, or building foundation, and typically the slowest.
Trenchless methods work through existing access points instead. Pipe bursting pulls a new pipe through the old one, breaking the old pipe outward as it goes. CIPP lining inserts a resin-coated liner into the existing pipe and cures it in place, creating a new pipe surface inside the old one. Both avoid excavating the full line, which is why trenchless is usually preferred in NYC's tighter, more built-up properties — but the right method for a given job depends on what the camera inspection shows.
A short, localized section of damage found early is generally a smaller job than a line with damage along most of its length — which is part of why we push for camera inspection before repair rather than after a full failure. Depth and access also matter: a line under a driveway or building foundation is more complex to reach than one under an open yard, regardless of repair method.
Trenchless repair generally costs more per foot than traditional digging, but the savings on excavation, landscaping restoration, and disruption often make it the more economical choice overall — especially on NYC properties where restoring a dug-up driveway or sidewalk adds real cost on top of the pipe work itself. We'll walk through both options and the trade-offs for your specific property before recommending one.
Building type matters here too. A single-family home typically has one line to assess. A multi-unit building may have a shared main line serving several units, or in some cases separate lateral lines per unit feeding into a shared main — which affects both diagnosis and how many units are impacted while work is underway. We'll confirm which setup your building has during the camera inspection.
We run a camera through your entire sewer line to see exactly what's happening — roots, cracks, offset joints, or a simple blockage that just needs clearing.
We show you the actual footage and present options: hydro-jetting, spot repair, or full replacement — with honest recommendations based on what the camera actually found.
We use trenchless methods where possible to minimize excavation. All work is NYC DOB compliant.
A final camera inspection confirms the line is fully clear. Full documentation provided.
