Serving Nassau & Suffolk Counties
Hear from Our Customers
When your sewer line fails, the last thing you want is a backhoe tearing through your driveway, garden beds, or that patio you just finished. Traditional excavation doesn’t just cost you in pipe repair—it costs you in restoration. In Nassau County, where the median home value sits around $658,700, property owners routinely spend $10,000 to $20,000 putting their yards back together after a conventional dig.
Trenchless pipe lining in Malverne, NY changes that equation entirely. We insert a resin-saturated liner through an existing access point, inflate it inside the damaged pipe, and cure it in place. What you’re left with is a seamless, jointless pipe within your old pipe—stronger than the original, rated to last 50+ years, and installed without a single shovel hitting your lawn.
Most residential projects finish in under a day. You’re not coordinating with landscapers for weeks. You’re not replanting shrubs or repaving asphalt. You’re just done.
Allied All City is a family-owned business that’s been serving Nassau and Suffolk Counties for over 40 years. We’re not subbing out the work or learning on the job. Our crews show up with the equipment, the experience, and the answers you’re looking for.
Malverne sits in the heart of Nassau County, where older homes come with older infrastructure. Clay pipes. Cast iron that’s corroded through. Root intrusion from mature trees lining every block. We’ve seen it all, and we’ve fixed it all—without ripping apart properties that homeowners have spent decades caring for.
When you call us, you’re talking to people who understand what Long Island winters do to frozen ground, what it costs to excavate during peak season, and why trenchless methods aren’t just convenient—they’re often the smarter financial move.
First, we inspect your line with a camera. That tells us exactly where the damage is, what caused it, and whether trenchless pipe lining in Malverne, NY is the right fix. If your pipe is collapsed or completely offset, we might recommend pipe bursting instead—but in most cases, lining works.
Once we confirm the approach, we clean the pipe thoroughly using high-pressure water jetting. Any roots, debris, or buildup gets cleared out so the liner can bond properly. Then we measure the damaged section and prep a custom epoxy liner to match.
The liner gets inserted through an access point—usually an existing cleanout or a small entry hole. We inflate it with air or water pressure, pressing it against the interior walls of your old pipe. While it’s inflated, the resin cures and hardens, typically within a few hours.
After curing, we deflate the bladder, pull it out, and reinstate any connections. What’s left behind is a smooth, corrosion-resistant pipe that’s structurally independent. It doesn’t rely on the old pipe for support. That’s why it lasts 50+ years, even if the host pipe continues to deteriorate.

Trenchless pipe lining services in Malverne, NY include a full camera inspection before and after the work, so you can see the problem and verify the repair. You’re not taking our word for it—you’re watching the footage yourself.
We handle the cleaning, the lining, the curing, and the reinstatement of any laterals or connections that were temporarily bypassed. If your issue involves a sewer line under your driveway, we’re not jackhammering through asphalt. We’re accessing the line from an endpoint and rehabilitating it in place. That’s the whole point.
Malverne’s housing stock skews older. Homes built in the 1940s through 1970s often have clay or cast iron sewer lines that crack under pressure from shifting soil, freeze-thaw cycles, and root intrusion from the tree-lined streets this village is known for. Trenchless pipe lining for old homes in Malverne, NY addresses those vulnerabilities without the collateral damage of excavation.
And because we’re local, we’re available year-round. Long Island winters make traditional digging expensive and slow—frozen ground adds days to the timeline and hundreds to the cost per foot. Trenchless methods work in any season, which means you’re not waiting until spring to fix a problem that’s backing up sewage into your basement today.
Trenchless pipe lining in Malverne, NY typically costs between $80 and $250 per linear foot, depending on pipe diameter, depth, and access conditions. That might sound like a wide range, but it reflects real variables—a shallow 4-inch residential sewer line costs less to line than a deep 6-inch line under a driveway.
Here’s the part most people miss: traditional excavation might quote lower for the pipe work itself, but you’re also paying to dig, haul soil, dispose of debris, and restore everything afterward. Landscaping, hardscaping, paving—it adds up fast. In Nassau County, restoration costs alone can hit $10,000 to $20,000 depending on what’s in the way.
Trenchless methods eliminate most of that. You’re paying for the repair and the technology, not the destruction. For a typical 50-foot residential sewer line, you’re looking at $4,000 to $8,000 all-in, with no additional restoration budget needed. And because the liner lasts 50+ years, you’re not doing this again in a decade.
Yes. That’s exactly what trenchless pipe lining was designed for. If your sewer line runs under your driveway, patio, or any other structure, we can rehabilitate it from an access point on either end—no jackhammering, no asphalt removal, no concrete demo.
We insert the liner through an existing cleanout or a small access hole, then guide it through the damaged section using camera equipment. Once it’s in position, we inflate and cure it in place. The driveway stays intact. You’re not paying a paving crew to come back and patch anything.
This is especially valuable in Malverne, NY, where driveways often sit over older clay or cast iron lines that have cracked from decades of freeze-thaw cycles and ground movement. Traditional methods would require cutting through asphalt, digging down four to six feet, replacing the pipe, backfilling, compacting, and repaving. That process takes days and costs thousands in labor and materials. Trenchless sewer repair in Malverne, NY gets it done in hours, with zero surface disruption.
Most residential trenchless pipe lining projects in Malverne, NY are completed in four to eight hours, start to finish. That includes the camera inspection, cleaning, liner installation, curing time, and final reinstatement. You’re typically looking at a single-day job unless the line is unusually long or there are access complications.
Compare that to traditional excavation, which can take three to five days once you factor in digging, pipe replacement, backfill, compaction, and scheduling restoration crews. And if the weather turns or the ground is frozen, those timelines stretch even further.
The curing process itself takes two to four hours depending on the method we use—some liners cure with heat, others with ambient air or UV light. Once cured, the pipe is immediately ready for use. There’s no waiting period, no extended downtime. If your sewer backs up on a Tuesday morning, we can have you back online by Tuesday afternoon in most cases.
Yes, as long as the pipe hasn’t completely collapsed. Trenchless pipe lining works on clay, cast iron, PVC, and even Orangeburg pipe—basically any material where the structure is still somewhat intact. Cracks, root intrusion, corrosion, offset joints—all of that can be rehabilitated with a cured-in-place liner.
What disqualifies a pipe is total collapse or a severe belly where the line has sagged so much that we can’t get a liner through. In those cases, we’d recommend pipe bursting, which is still trenchless but involves pulling a new pipe through while breaking up the old one.
Malverne has a lot of homes built between the 1940s and 1970s, and many still have their original sewer lines. Clay pipes crack as soil shifts. Cast iron corrodes from the inside out, especially in areas with acidic groundwater. Both are prime candidates for trenchless pipe lining in Malverne, NY because the liner creates a brand-new pipe inside the old one—structurally independent, corrosion-proof, and rated to outlast the original by decades.
Yes. CIPP (cured-in-place pipe) liners are engineered to last a minimum of 50 years, and many manufacturers warranty them for that long. The material itself—typically a fiberglass or polyester fabric saturated with epoxy resin—is highly resistant to corrosion, root intrusion, and chemical degradation. It doesn’t rust, crack, or break down the way clay or cast iron does.
The liner becomes the pipe. Once cured, it’s a seamless, jointless tube that doesn’t rely on the host pipe for structural support. Even if the old pipe continues to deteriorate around it, the liner holds its shape and function. That’s why municipalities use this same technology for water mains and sewer infrastructure—they need repairs that last, and they need them done without shutting down entire streets.
For homeowners in Malverne, NY, that means you’re making a one-time investment in a repair that outlives most mortgages. You’re not patching the problem or kicking it down the road. You’re solving it permanently, without tearing up the property you’ve spent years maintaining.
Yes, and that’s one of its biggest advantages. Traditional excavation in winter is a nightmare on Long Island. Once the ground freezes below the frost line—about three feet deep in Nassau County—you’re dealing with soil that’s hard as concrete. Excavators struggle, timelines double, and costs can jump 200% to 300% because of the equipment and labor required to break through frozen ground.
Trenchless pipe lining in Malverne, NY doesn’t require digging, so frozen ground isn’t an issue. We’re working inside the pipe, not around it. As long as we can access the line and the resin can cure properly (which we control with heat or UV), the repair proceeds as normal.
That means if your sewer backs up in January, you’re not waiting until April for a fix. We can respond the same day, assess the line, and complete the repair without dealing with frost, frozen soil, or weather delays. For emergency situations—and sewer backups are always emergencies—that responsiveness matters.
