Most homeowners never think about their sewer line — until it fails. The main sewer line is the single pipe that carries all wastewater from every drain, toilet, and appliance in your home out to the municipal sewer system or septic tank. When it slows down, backs up, or breaks, nothing in your home drains properly.
The challenge with sewer line problems is that they’re hidden underground, which means most people don’t know there’s an issue until it’s already serious. ONG Plumbing & Heating uses camera inspection technology to see exactly what’s happening inside your sewer line before recommending any work — so you get an accurate diagnosis, a fair price, and a repair that actually solves the problem.
Sewer Line Services for Residential & Commercial Properties
Over time, sewer lines accumulate grease, scale, mineral deposits, debris, and in older properties, tree root intrusion. A partial blockage can slow every drain in your home for months before it becomes a full backup. ONG clears sewer line blockages using heavy-duty professional augering equipment, removing the obstruction completely and restoring full flow. We follow every cleaning with a camera inspection to confirm the line is clear end to end.
Not every sewer line problem requires a full replacement. Cracks, joint separations, small collapses, and localized root damage can often be repaired at the affected section rather than replacing the entire line. ONG uses camera inspection to identify the exact location and extent of the damage, then excavates precisely where needed to make the repair — minimizing disruption to your yard, driveway, or landscaping. All repairs are completed to current code and backed by our 1-year guarantee.
When a sewer line is severely deteriorated, has collapsed in multiple places, or is made of outdated material such as clay or Orangeburg pipe, full replacement is the most reliable long-term solution. ONG handles the entire replacement process in-house — camera inspection, excavation, removal of the old line, installation of new PVC pipe, backfill, and site restoration. No subcontractors, no coordination headaches, one point of contact from start to finish.
Every sewer line job starts with a camera inspection. We don’t guess, we don’t assume, and we don’t recommend work you don’t need. You see the footage, we explain the findings, and we agree on the right course of action together before any digging begins.

A sewer line that repeatedly backs up may have a structural problem rather than a simple blockage. Cracks, separated joints, root intrusion, deterioration, or a partially collapsed section can allow the same symptoms to return even after the line is cleared.
Common warning signs include frequent main-line stoppages, wastewater backing up into lower fixtures, persistent sewer odors, soggy areas near the sewer route, or a history of repeated drain cleaning. These symptoms do not prove the pipe is damaged, but they are reasons to investigate before continuing with temporary fixes.
When conditions allow, a sewer camera inspection can help show whether the line has a visible defect and where the affected section is located.
Not every sewer problem requires replacement of the entire line. If damage is limited to one section, a targeted repair may be appropriate. If the pipe is badly deteriorated, has multiple failures, or is in poor condition over a longer distance, replacement may make more sense.
The decision depends on pipe material, depth, access, the location of the defect, and the condition of the rest of the line. We explain what we find and the practical options before major work begins.
When underground access is required, our plumbing excavation service covers the process of exposing and repairing damaged underground piping.
We start with the symptoms and the history of the line. If the pipe is blocked, flow may need to be restored before inspection is useful. If a camera can travel through the line, it may reveal roots, offsets, cracks, standing water, or other visible conditions that help define the repair area.
Once the problem is reasonably identified, we can discuss whether cleaning, localized repair, or replacement is the appropriate next step. The goal is to avoid unnecessary excavation and to base the repair on evidence whenever possible.
For customers in Bethlehem, Allentown, Easton, and surrounding Lehigh Valley communities, you can request a quote for sewer-line evaluation and repair.
How do I know if my sewer line is broken?
Repeated backups, camera findings, visible settlement, or recurring problems in the same area can suggest damage, but diagnosis is needed before repair.
Can you repair just one section?
In many cases, a localized repair may be possible if the rest of the line is in serviceable condition.
Do you always need to excavate?
No. Excavation depends on the type and location of the defect and the repair method being used.
Can a camera inspection locate the problem?
A camera can often help identify visible defects and estimate where they are located in an accessible line.
What areas do you serve?
We serve Bethlehem and surrounding Lehigh Valley communities, including Allentown, Easton, and nearby areas.
