Serving Nassau & Suffolk Counties

Traditional excavation turns your yard into a construction zone. Trenches four to six feet deep. Torn-up driveways. Destroyed landscaping. Then you’re stuck paying to restore everything after the work is done.
Horizontal directional drilling changes that. We drill underground pathways for water lines, gas lines, electrical conduits, and sewer connections without surface disruption. Your lawn stays intact. Your driveway doesn’t get touched. Your trees and gardens remain undisturbed.
The process is faster, cleaner, and costs less overall because you’re not paying twice—once for installation and again for restoration. You get functional utility lines installed exactly where they need to go, and your property looks the same as it did before we arrived.
Allied All City has been family-owned and operated since 1983. We’ve spent over 40 years installing and repairing utility infrastructure across Nassau and Suffolk Counties, including West Bay Shore, Bay Shore, East Islip, Oakdale, and Sayville.
We’re not a franchise or a national chain. We’re local contractors who understand Long Island soil conditions, local permit requirements, and the specific challenges West Bay Shore property owners face with aging water and sewer infrastructure.
Whether you’re a homeowner dealing with a failing water service line or a contractor who needs trenchless installation for a commercial project, we handle the full scope—permitting, drilling, installation, and inspection.
We start with a site assessment to map your existing utilities and determine the best drilling path. This prevents damage to water mains, gas lines, electrical conduits, or communication cables already underground.
Next, we drill a small pilot hole along the planned route using a steerable drill head. The drill follows a precise underground path—under driveways, sidewalks, roads, or landscaping—without breaking the surface. Once the pilot hole reaches the exit point, we attach the new utility line and pull it back through the drilled pathway.
The entire process typically takes a day or two, depending on distance and soil conditions. You’ll see two small entry and exit points, but no trenches, no excavation, and no need for landscape restoration. After installation, we pressure-test water lines or inspect gas lines to confirm everything functions correctly before backfilling the small access points.

We handle trenchless gas line installation, water line directional drilling, electrical conduit placement, and sewer line connections. Pipe diameters range from 1 inch to 4 inches, and we work with PVC, HDPE, copper, and steel depending on your utility type and local code requirements.
West Bay Shore properties often need water service replacements due to aging galvanized pipes or lead service lines. Directional drilling allows us to install new water lines from the street to your home without digging up your driveway or front yard. Same goes for gas line upgrades—if you’re converting to natural gas or replacing old steel lines, we can route new lines underground without surface disruption.
We also install electrical conduits for pool equipment, outdoor lighting, or detached structures, and fire suppression water lines for commercial properties. If your project involves crossing under a county road, existing structure, or protected landscaping, trenchless methods are often the only practical option. Long Island’s dense infrastructure and high property values make traditional excavation costly and disruptive—directional drilling solves both problems.
Directional drilling typically costs between $10 and $30 per linear foot, depending on soil conditions, pipe diameter, and site access. That might sound higher than open-cut trenching at first, but the total project cost is usually lower.
Traditional excavation requires cutting through driveways, sidewalks, or landscaping, then restoring everything afterward. Asphalt replacement, concrete repair, sod installation, and landscape restoration can easily add thousands of dollars to your final bill. With trenchless methods, you avoid those restoration costs entirely.
You also save time. Traditional projects can take a week or more when you factor in excavation, utility installation, inspections, and surface restoration. Directional drilling projects in West Bay Shore, NY typically finish in one to two days, which means less disruption to your daily routine and faster access to the utilities you need.
Yes. That’s exactly what trenchless directional drilling is designed to do. We drill underneath your driveway, creating an underground pathway for the new water line without breaking the surface.
The process starts with a small entry point on one side of the driveway and an exit point on the other. We use a steerable drill head to bore horizontally beneath the asphalt or concrete, then pull the new water line through the drilled path. Once the line is in place, we connect it to your home’s plumbing system and the municipal water main.
Your driveway remains intact throughout the entire process. No sawcutting. No jackhammering. No asphalt removal or concrete patching. This approach is especially valuable in West Bay Shore, where many homes have established driveways and mature landscaping that would be expensive to replace after traditional excavation.
West Bay Shore sits on Long Island’s coastal plain, which means you’re dealing with a mix of sandy soils, glacial till, and occasional clay layers. Sandy soils are ideal for directional drilling because they’re easy to penetrate and stable enough to hold the drilled pathway.
Clay layers can slow down the drilling process and require adjustments to drilling fluid pressure, but they’re manageable with the right equipment. Rocky soils or areas with large boulders can complicate drilling, though Long Island generally has fewer subsurface rock obstacles compared to other regions.
We assess soil conditions during the planning phase using existing utility maps, site observations, and sometimes test borings for larger projects. This helps us choose the right drill bit, adjust drilling angles, and anticipate any obstacles before we start. The goal is to complete the installation efficiently without surprises that could delay your project or increase costs.
Most residential trenchless gas line installations in West Bay Shore, NY take one to two days from start to finish. The timeline depends on the distance between your gas meter and the street connection, soil conditions, and whether we’re crossing under driveways or other obstacles.
Day one typically involves site preparation, utility locating, and the actual drilling and pipe installation. We’ll drill the underground pathway, pull the new gas line through, and make the necessary connections to your home’s gas system and the utility company’s main line.
Day two covers pressure testing, inspections, and final connections. Gas lines require rigorous testing to confirm there are no leaks, and we coordinate with the local utility company for final meter hookup and activation. If your project is straightforward with good soil conditions and clear access, we can sometimes complete everything in a single day. Larger commercial installations or projects with complications may take longer, but you’ll know the timeline upfront.
Yes, but directional drilling typically requires fewer permits than traditional excavation. You’ll need a plumbing permit for water or gas line installations, and possibly a right-of-way permit if the drilling crosses under a public street or sidewalk.
The good news is that trenchless methods often streamline the permitting process because you’re not disturbing the surface. Traditional open-cut projects require street opening permits, traffic control plans, and sometimes environmental reviews if you’re digging near wetlands or protected areas. Directional drilling avoids most of those complications.
We handle permit applications as part of our service. We’ll submit the necessary paperwork to the Town of Islip and coordinate with the Suffolk County Department of Health Services if your project involves water or sewer connections. You don’t need to navigate the bureaucracy yourself—we manage the process and keep your project moving forward without unnecessary delays.
We take extensive precautions to prevent utility strikes. Before any drilling starts, we contact New York 811 to have all underground utilities marked. This includes water mains, gas lines, electric cables, communication lines, and sewer pipes.
We also use electronic locating equipment to track the drill head’s position in real time as it moves underground. This allows us to steer around existing utilities and adjust the drilling path if we detect an obstacle. The drill head sends a signal to a receiver on the surface, giving us precise depth and location data throughout the entire drilling process.
If we do encounter an unexpected utility that wasn’t marked or mapped, we stop drilling immediately and reassess. In over 40 years of operation across Nassau and Suffolk Counties, our focus on thorough utility locating and careful drilling practices has kept utility strikes extremely rare. The combination of professional locating services, real-time tracking technology, and experienced operators makes trenchless directional drilling one of the safest methods for underground utility installation.
