Yes. Allied All-City holds current Nassau County plumbing licenses and certifications that meet all county regulatory requirements. This matters because Nassau County has its own licensing framework that is separate from New York State's general contractor licensing — performing certain types of plumbing and sewer work in Nassau County without the appropriate county credentials puts homeowners at risk of failed inspections, voided permits, and potential liability. Our plumbers are credentialed to perform all categories of work in Nassau County, including drain cleaning, water line work, sewer repair and replacement, and emergency services.
Allied All-City plumbers handle the full spectrum of residential and commercial plumbing work in Nassau County. This includes emergency plumbing repairs, burst and frozen pipe repair, drain cleaning, sewer camera inspection, sewer line repair and trenchless replacement, water main and service line repair and installation, water heater service, fixture replacement, grease trap service, and sump pump installation and repair. We also provide cesspool pumping and environmental services for properties that need them. Essentially, if it involves water, drain, or sewer systems on a Nassau County property, Allied All-City has the expertise and equipment to address it.
Allied All-City provides 24/7 emergency plumbing response throughout Nassau County. We dispatch our own crews directly — no subcontractor coordination required — which allows us to move quickly once a call comes in. While response times vary based on location and current demand, our goal for urgent emergencies is to have a plumber en route as fast as possible, often within the hour for communities across Nassau County. Areas like Hempstead, Garden City, Valley Stream, Freeport, Mineola, and Long Beach are all well within our rapid response range. We understand that a plumbing emergency is not something you wait on, and we don't ask you to.
Absolutely — in fact, it's something we specialize in. Nassau County's housing stock includes a large number of pre-war and post-war homes with original galvanized steel water supply lines, cast iron drain and sewer pipes, and lead service connections that have long since exceeded their useful life. Our plumbers are experienced in diagnosing and repairing these older systems safely and correctly. Communities like Elmont, Hempstead, Lynbrook, and Long Beach have significant concentrations of this older housing, and our crews know what to expect when they open up a wall or run a camera through a drain in these neighborhoods. We can also advise on when partial or full repiping makes the most sense economically.
Trenchless sewer replacement is a technology that allows a failing or collapsed sewer pipe to be repaired or replaced without traditional open excavation. Instead of digging a trench the full length of the pipe, our crews access the line from one or two small entry points and either insert a resin-saturated liner that hardens in place (cured-in-place pipe, or CIPP) or pull new pipe through the existing trench using a bursting head. The result is a code-compliant sewer line with minimal surface disruption. Allied All-City offers trenchless sewer services throughout Nassau County, making it an excellent option for homeowners in Garden City, Massapequa, Great Neck, Roslyn, and other areas where protecting driveways and landscaping is a priority.
Allied All-City has maintained a strict no-subcontractor policy for its entire history. Every person dispatched to your property is a direct employee of Allied All-City Inc. — trained, vetted, and held to our internal standards for quality, professionalism, and code compliance. This isn't just a selling point; it's a fundamental part of how we operate. When you call us, the crew that shows up is our crew — they carry our insurance, follow our procedures, and are accountable to us and to you. For Nassau County homeowners in Valley Stream, Mineola, Roslyn, Massapequa, or anywhere else in the county, that means you know exactly who is in your home and who is responsible for the work being done.
