Sewer Line Replacement in Delaware County, PA

Sewer line replacement is the right call when a pipe is beyond repair — crushed, collapsed over a significant span, severely offset at multiple joints, or made of Orangeburg that has softened and deformed past the point where a liner can pass through. Advanced Drains & Underground Solutions handles both trenchless replacement (pipe bursting) and conventional excavation in Delaware County, and we recommend the method based on what the camera shows, not on what earns more.

When Replacement Is Necessary

Most pipe problems in Delaware County’s older housing stock — clay tile laterals from the 1920s through the 1950s, cast iron from the same era, Orangeburg from the mid-century period — can be lined without full replacement. But lining requires a structurally intact host pipe. If the pipe is crushed at multiple points, collapsed over a significant run, or so heavily offset that a liner cannot pass through, replacement is the only reliable option.

A camera inspection tells us which situation you are in. We scope the line before any discussion of replacement, because misdiagnosing a lineable pipe as a replacement job adds significant cost the homeowner does not need to bear.

What Does Sewer Line Replacement Cost in Delaware County?

The two variables that drive cost are the lateral length and the method required. Trenchless pipe bursting on a typical Delaware County residential lateral — usually 40 to 80 feet from the foundation to the main in the street — runs meaningfully less in total cost than conventional excavation on the same run, because excavation requires surface restoration (lawn, sidewalk, driveway) that adds to the final bill. The offset is that pipe bursting requires an open passage for the bursting head; if the pipe has already collapsed and closed off, excavation is necessary regardless of preference.

We do not post a fixed price list because lateral length, depth, and soil conditions vary enough between properties that any posted number would mislead you. What we do: we camera the line, tell you exactly what we found, quote the method that addresses the problem, and then match or beat any written estimate from another licensed contractor. The camera inspection is credited toward any repair we perform, so it costs you nothing if we do the work.

As a general reference for Delaware County homeowners comparing options: trenchless pipe bursting on a residential lateral typically costs more upfront than a simple repair but substantially less than conventional excavation once you factor in surface restoration. On laterals where the difference is close, we will show you the numbers for both methods and let you decide.

Trenchless Pipe Bursting vs. Conventional Excavation

Pipe Bursting (Trenchless Replacement)

Pipe bursting pulls a new HDPE (high-density polyethylene) pipe through the old lateral while simultaneously fracturing the old pipe outward into the surrounding soil. It requires access pits at each end — one near the foundation cleanout and one at the main connection point — but does not require opening the full length of lawn, driveway, or landscaping along the pipe run. HDPE is continuous with no joints for root intrusion and carries a service life of 50 years or more under normal conditions.

Pipe bursting works well in most Delaware County soil conditions, including the clay-heavy profiles common in older residential neighborhoods. It is not suitable when the old pipe has already collapsed and closed off — the bursting head needs an open passage to enter. In those cases, excavation is necessary.

Conventional Excavation

Excavation opens a trench along the failing pipe run and replaces it with new PVC or HDPE. This is the right tool when the pipe cannot accept a bursting head, when there are multiple branch connections along the run that need to be preserved, or when a shared party lateral in a twin or row home requires careful separation of adjacent units’ connections. Surface restoration — lawn, sidewalk, or driveway — is completed as part of the job.

Permits and DELCORA Compliance

Sewer lateral work in Delaware County requires a permit from your township or borough, and in some cases coordination with DELCORA — the Delaware County Regional Water Quality Control Authority, which manages sewage treatment for most of the county. We handle the permit application and inspection scheduling as part of the job. You do not need to navigate the township process on your own.

What to Expect During a Trenchless Replacement

We start with a camera inspection to confirm the diagnosis and map the lateral. On the day of work, we establish access pits at the foundation end and the street end, typically 18 to 24 inches wide. The bursting head enters through the foundation pit and is pulled toward the street, fracturing the old pipe outward while drawing the new HDPE behind it. We test the new line and run a post-installation camera before we leave. Most Springfield Township and Delaware County residential laterals are back in service the same day.

Frequently Asked Questions: Sewer Line Replacement in Delaware County

How do I know if my sewer line needs replacement vs. repair?

A camera inspection is the only honest answer. Pipes that have isolated cracks, root intrusion through one or two joints, or moderate internal corrosion are usually candidates for lining — repair without replacement. Pipes that are crushed at multiple points, collapsed over a long span, or made of Orangeburg that has deformed need replacement. We will show you what the camera found and explain which category your pipe falls into.

How long does sewer line replacement take?

Most residential trenchless replacements in Delaware County are completed in a single day. Conventional excavation on longer runs may require two days depending on depth and surface restoration scope. We give you a timeline at the time of the estimate.

Does the new pipe come with a warranty?

Yes. New HDPE installed by pipe bursting carries a manufacturer’s warranty on the pipe material, and we warranty our installation work. We put both in writing before the job starts.
