Drain Cleaning & Sewer Line Repair in Wilmington, DE

Wilmington’s housing stock is some of the oldest in the Mid-Atlantic, and that shows up underground every single day. From the brick rowhomes of Little Italy and Hilltop to the early-1900s twins in Trolley Square and the stately Victorians of Highlands and Cool Spring, a huge share of the city was plumbed with clay tile and cast-iron laterals that are now 70, 90, even 100-plus years old. Those pipes don’t fail politely. They crack at the joints, scale up with rust, and pull in roots from the mature street trees that line neighborhoods like Wawaset Park and Forty Acres. When a 1920s lateral finally lets go under a Wilmington rowhome, you get the classic signs: a slow-draining basement floor drain, gurgling toilets, or sewage backing up in the lowest fixture in the house.

Advanced Drains is a licensed plumbing and underground-utility contractor (PA HIC PA151129) that does drain and sewer work the right way: diagnose first with a camera, then fix exactly what’s broken. We carry a 4.8-star rating across 745+ Google reviews, and we serve Wilmington homeowners with same-day and next-day appointments.

Drain Cleaning in Wilmington

Grease, soap scale, and root intrusion are the three things that clog Wilmington drains. In the older neighborhoods off Union Street and Delaware Avenue, the cast-iron stacks have decades of buildup narrowing a 4-inch pipe down to two. We clear kitchen lines, main lines, and basement drains with the right tool for the pipe — not a one-size-fits-all snake that just punches a hole through a grease plug. If your line backs up repeatedly, that’s a symptom, and we’ll tell you what’s actually causing it.

Sewer Line Repair Near Me — Wilmington

When the problem is the lateral itself — the pipe running from your home out to the city main under New Castle County streets — we repair or replace it. Offset joints, bellied sections that hold water, and root-shattered clay are everyday finds in this city. We give you a free written estimate and we’ll beat any written estimate by 10%.

Trenchless & CIPP Pipe Lining

Digging up a lateral under a Wilmington rowhome’s front steps, sidewalk, or a mature-tree parkway is destructive and expensive. That’s why we do trenchless cured-in-place pipe (CIPP) lining in-house — we don’t subcontract it. We pull a resin-saturated liner through your existing pipe and cure it in place, creating a new seamless pipe inside the old one. No trench across your yard, no torn-up brick walkway, and a structural fix that outlasts the cast iron it replaced. For homes where lining isn’t the right call, we also do conventional dig-and-replace.

Free Camera Inspection

Every job starts with a free sewer-camera inspection and written estimate. We push a camera down the line so you can see the crack, the root mass, or the collapse yourself — no guessing, no upselling a repair you don’t need. Learn more about our sewer camera inspections.

Hydro Jetting

For heavy grease, scale, or root-fouled lines, hydro jetting scours the pipe wall back to full diameter with high-pressure water — far more thorough than cabling alone. It’s the right prep before a CIPP lining, and the right fix for restaurants and older multi-unit buildings along the city’s commercial corridors.

Frequently Asked Questions

Do you serve all of Wilmington, DE?

Yes. We serve homeowners across Wilmington and New Castle County — including Trolley Square, Little Italy, Highlands, Wawaset Park, Forty Acres, Cool Spring, and the surrounding neighborhoods — with same-day and next-day appointments.

How much does sewer line repair cost in Wilmington?

It depends on the length of the lateral, the depth, and whether the fix is a spot repair, a full trenchless lining, or a dig-and-replace. We give you a free camera inspection and a free written estimate before any work, and we’ll beat any competitor’s written estimate by 10%.

Is trenchless sewer repair really less disruptive?

Yes. Because we line the existing pipe in place, there’s no trench across your yard, sidewalk, or front steps. For Wilmington rowhomes with brick walkways and mature street trees, trenchless CIPP — which we do in-house, not subcontracted — usually means the repair is done in a day with no demolition.
