Drain Cleaning & Sewer Line Repair Across Chester County, PA

Chester County covers a lot of ground — from the rowhome-lined streets of Coatesville and Phoenixville to the historic borough core of West Chester, the growing developments around Exton and Downingtown, and the quieter Brandywine Valley townships near Kennett Square and Malvern. Advanced Drains has served homeowners across all of it. We are a licensed Pennsylvania home improvement contractor (PA HIC #PA151129) rated 4.8 stars across 745+ Google reviews, and we handle drain cleaning, sewer line repair, trenchless replacement, camera inspection, and hydro jetting from one in-house crew — no subcontractors.

This is one of the most geographically split counties we work. The eastern edge around West Chester borough, Glen Mills, and the townships fronting Route 1 is dense, sewered, and old; the western and southern reaches toward the Octoraro and the Maryland line are rural, well-and-septic, and spread thin. That split is the whole story for sewer work here. In the borough we are pulling roots out of laterals laid before World War II; ten miles west we are camera-ing a 200-foot run out to a septic tank under a horse pasture. One crew, two completely different problems — and we keep the equipment for both on the truck.

Why Chester County Sewer Lines Fail

Chester County’s housing stock is a study in extremes, and each era brings its own sewer problems. The pre-1940 homes in West Chester borough — the brick twins and Victorians along Gay Street, High Street, and the leafy blocks above Miner Street near the university — were plumbed with vitrified clay and cast-iron laterals. Clay joints separate over decades and invite root intrusion; cast iron scales, flakes, and channels along the bottom until it collapses. The mature sycamores and oaks shading those streets are exactly what crush the pipe running under the front pavement, and a borough lateral that has to cross a brick sidewalk and a tree lawn before it reaches the main is a classic root-and-offset job.

The postwar and 1960s–70s subdivisions filling in around Exton, Thorndale, and the Downingtown corridor often used Orangeburg (tar-paper) pipe, which delaminates and goes oval until it pancakes shut. We see it constantly in that middle band of the county — the developments that went up along the Route 30 bypass and the Amtrak line. Newer construction in the southern and eastern townships — the cul-de-sac neighborhoods around Glen Mills, Concordville, and the Route 202 / Route 1 spine near Brinton Lake and Chadds Ford — runs on PVC, which fails differently: belly-forming settlement, crushed sections from heavy backfill, and offset joints where the ground shifts on the rolling terrain above Chester Creek and the Brandywine.

Then there is the rural half of the county. West of Marshallton, out toward Marsh Creek State Park, Wallace, and the Octoraro watershed, most homes are on private lateral runs to septic and on-lot systems — runs far longer than a borough lateral, often crossing a driveway, a field, or a stream easement before they reach the tank. That length means more pipe, more joints, and more places for a clog, a root, or a break to hide. On these properties a sewer camera and locator earn their keep: instead of guessing where a 180-foot run failed, we put the camera down, mark the spot from the surface, and dig — or line — only where the problem actually is.

Our Chester County Services

• Drain cleaning — kitchen, bath, main-line, and floor-drain backups cleared with cable machines and root cutters. We find the cause, not just the symptom.
• Sewer line repair & replacement — spot repairs on a collapsed section, or full lateral replacement when the run is shot. The long septic laterals out in the western townships are our bread and butter for this.
• Trenchless / CIPP lining — we rehabilitate failing laterals with cured-in-place pipe lining done in-house, so your driveway, mature landscaping, and the historic streetscapes of West Chester or Phoenixville stay intact. No subcontractor markup, no open trench across the front lawn.
• Camera inspection — we put a sewer camera down the line to show you exactly what is wrong and how far out it is, with a free camera inspection and written estimate. On long rural runs we locate the defect from the surface so excavation stays surgical.
• Hydro jetting — high-pressure water that scours grease, scale, and root mass off the pipe walls, restoring full diameter on lines a cable only punches a hole through.

We offer same-day and next-day service across Chester County, and we will beat any written estimate by 10%. Whether you are a West Chester homeowner with a clay lateral full of roots, a Glen Mills family on a PVC line with a settling belly, or a Wallace or Honey Brook property owner facing a long septic run gone bad, we bring the diagnosis and the fix to your door.

Frequently Asked Questions

Do you serve all of Chester County or just the bigger towns?
All of it. We work West Chester, Coatesville, Phoenixville, Exton, Downingtown, Malvern, Kennett Square, Glen Mills, and the surrounding townships — including the rural western corner out toward Marsh Creek and the Octoraro. If you have a drain or sewer issue anywhere in the county, call us — we run one crew across the whole region.

Will I have to dig up my yard to fix a broken sewer line?
Usually not. We do trenchless sewer repair and CIPP lining in-house, which rehabilitates the pipe through existing access points without trenching across your lawn or driveway. After a camera inspection we will tell you honestly whether trenchless or a dig is the right call for your line.

How do I know what is actually wrong with my sewer?
We run a sewer camera inspection down the line — free with your estimate — so you see the clay joint, the root mass, the belly, or the break on screen before you spend a dollar. You get a written estimate, and we beat any competing written estimate by 10%.
