Plumbing Services

At ZSL Plumbing, we believe that integrity forms the foundation of every successful project. Our team approaches each job with the same level of care and attention we'd give to our own homes, treating customers like family rather than just another service call. Founded in 2021 but backed by over two decades of industry experience, our locally owned family business has quickly established a reputation for excellence throughout Suffolk County, NY. We understand that plumbing emergencies rarely happen at convenient times, which is why we prioritize responsiveness—answering calls within an hour and completing most service calls the same day. Our commitment to quality isn't just talk; it's backed by our 100% satisfaction guarantee and comprehensive warranty coverage that protects your investment.

What truly sets us apart is our dedication to accessibility and fairness. We offer free, on-demand phone estimates so you can make informed decisions without pressure. Our team is bilingual in English and Mandarin, ensuring clear communication with more members of our community. We recognize the importance of professional credentials in our industry, which is why we maintain proper licensing and insurance, along with specialized certifications like National Grid Task 86/87 and Certified Halo Water System installation. We understand that plumbing work can be financially challenging, so we've implemented financing options and special discounts for seniors, veterans, and civil service members. When unexpected issues arise that might involve insurance claims, we'll guide you through that process too, making a potentially stressful situation much more manageable. Contact us today!

We install new hose bibs and repair existing ones, addressing issues like leaks, broken handles, or frost damage that commonly affect these outdoor fixtures.

Regular plumbing inspections can identify potential issues before they become costly emergencies.

We provide detailed reports with clear recommendations, helping you prioritize repairs and maintenance based on urgency and budget considerations.
