Trenchless Sewer Repair on the Main Line, PA

A broken sewer lateral on the Main Line usually means a 60- to 100-year-old clay or cast iron line running under a mature lawn, a stone retaining wall, or a driveway that was never meant to be dug up. Advanced Drains & Underground Solutions repairs those lines without excavation — CIPP (cured-in-place pipe) lining and pipe bursting — so the property stays intact.

No-Dig Sewer Lateral Repair: CIPP Lining and Pipe Bursting

Two trenchless methods cover most Main Line sewer lateral failures:

• CIPP (cured-in-place pipe) lining — a resin-saturated liner is pulled or inverted into the existing pipe and cured in place, forming a new pipe inside the old one. Best for cracks, offset joints, and root intrusion where the pipe’s original shape and size still work.
• Pipe bursting — a bursting head is pulled through the old pipe, fracturing it outward while simultaneously pulling in a new HDPE pipe of the same or larger diameter. Used when the line is collapsed, badly bellied, or undersized.

Both methods go in through existing access points — a cleanout or a small entry/exit pit — instead of a trench the full length of the lateral.

What No-Dig Repair Protects

Main Line properties carry the kind of hardscape and landscaping that a trench crew can’t put back the way it was: fieldstone walls, mature trees with root systems tied into the yard, brick and paver driveways, in-ground irrigation. Trenchless repair works around all of it because the dig footprint is a pit or two, not a trench.

Lower Merion Township Permits, Handled

Sewer lateral work in Lower Merion Township requires a licensed contractor registered with the township and, when the lateral runs under the street, a Public Works right-of-way (ROW) permit. We hold the township contractor license and pull the ROW permit as part of the job — homeowners don’t deal with the township directly.

Camera Inspection First — $450, Credited to Your Repair

Every job starts with a camera inspection of the lateral: $450, and if you move forward with the repair, that $450 is credited against the job. You see the actual condition of the pipe before you commit to a repair method or a price.

Price in Writing. We Beat Any Written Estimate.

You get a price in writing before work starts — no verbal estimates. If you already have a written quote from another licensed contractor, bring it: we’ll beat it, and if you want a second opinion before deciding, that review is free when you bring the competing quote.

Serving the Main Line

Lower Merion Township

Covers Ardmore, Bala Cynwyd, Wynnewood, Merion, Merion Station, Gladwyne, Penn Valley, and Bryn Mawr — the full township. We hold the Lower Merion contractor license and pull ROW permits for street-side lateral work here directly.

Ardmore, PA

Older twin and rowhome blocks in Ardmore commonly run clay laterals from the 1920s-40s under narrow front yards and shared driveways — CIPP lining is usually the right fit where the original pipe is still round.

Bala Cynwyd, PA

Bala Cynwyd properties near City Avenue and along the older residential blocks often have laterals tied into shared or aging township lines; a camera inspection confirms whether the failure is on the private lateral or the township main before any work is quoted.

Wynnewood, PA

Larger lot sizes in Wynnewood mean longer lateral runs and more established landscaping between the house and the street connection — trenchless repair keeps that yard intact.

Merion & Merion Station, PA

Stone and older masonry homes in Merion and Merion Station frequently sit on laterals that predate modern plastic pipe entirely; pipe bursting handles the collapsed or badly offset sections that lining can’t fix.

Narberth, PA

Narberth’s tight lot lines and close-set driveways make trench work especially disruptive to neighboring properties — a strong case for no-dig repair even on short lateral runs.

Bryn Mawr, PA

Bryn Mawr’s larger, established properties — mature trees, stone walls, long driveways — are exactly what trenchless repair is built to work around.

Gladwyne, PA

Gladwyne properties often have longer laterals running through wooded or landscaped lots; we scope the full run by camera before recommending lining or bursting.

Penn Valley, PA

Penn Valley’s mix of older and newer construction means lateral material varies block to block — the camera inspection tells us exactly what we’re repairing before we quote a method.

Haverford, PA

Haverford Township laterals share the same permit process as Lower Merion — a licensed contractor and, for street-side work, a township right-of-way permit, both handled by us.
