Yes. Allied All-City Inc. holds all required Nassau County licenses and certifications for plumbing, sewer work, and environmental services. We comply with Nassau County Department of Public Works standards and all applicable local codes. Our certifications cover everything from routine drain cleaning and water line work to sewer replacement and environmental remediation. Unlike some contractors who work informally or rely on a general license, we maintain current, county-specific credentials — which matters when your job needs to pass a county inspection or involves permitted utility work near public infrastructure.
No — never. Allied All-City operates exclusively with our own direct crews. We do not subcontract any portion of our work to third-party companies. This is a core company policy we have maintained for over 50 years. What it means for Nassau County customers is that the people who show up at your door are Allied All-City employees — trained, vetted, and accountable to us. There's no handoff, no confusion about who's responsible, and no scenario where a subcontractor cuts corners on a job we've committed to completing correctly.
Allied All-City serves all of Nassau County, including Hempstead, Garden City, Valley Stream, Great Neck, Roslyn, Mineola, Freeport, Oceanside, Massapequa, Long Beach, Lynbrook, Elmont, and all surrounding communities. Whether you're in a high-density area like Hempstead or a quieter residential pocket in Roslyn Heights, our crews cover the full county. We are deeply familiar with the local infrastructure — from the sewer systems and water main layouts of Nassau's South Shore communities to the private well and cesspool configurations more common in the county's less-densely developed areas.
Allied All-City provides 24/7 emergency response throughout Nassau County. Response times vary based on location and demand, but our goal is to have a crew en route to your property as quickly as possible — often within the hour for urgent situations. Because we stage vehicles and crews across the region and do not rely on subcontractors, we can dispatch directly without coordinating with a third party. For major emergencies like main line breaks, sewer backups, or burst pipes in areas like Valley Stream, Freeport, or Garden City, fast response is critical, and it's something we take seriously every single day.
Allied All-City offers a comprehensive range of services for Nassau County residential and commercial customers. These include emergency plumbing repairs, drain cleaning, sewer line inspection and repair, trenchless sewer replacement, water line repair and installation, cesspool pumping and maintenance, grease trap service, environmental services, and specialty cleaning. We work on everything from a single clogged drain in a Lynbrook home to a full sewer lateral replacement on a commercial property in Mineola. If it involves plumbing or underground utility infrastructure in Nassau County, we have the equipment and expertise to handle it.
Allied All-City has served Nassau County for more than 50 years as a family-owned company — not a franchise, not a private equity-backed national chain. That history means we have a genuine stake in this community and a track record that spans generations of homeowners. We bring Nassau County-specific knowledge that out-of-area contractors simply don't have: the post-war pipe systems in Elmont and Hempstead, the drainage challenges along the South Shore, the older clay sewer laterals in Great Neck and Roslyn. Combined with our no-subcontractor policy, county certifications, and 24/7 availability, Allied All-City offers a level of accountability and local expertise that is genuinely difficult to find elsewhere on Long Island.
