For a business, a plumbing problem is not just an inconvenience — it is closed restrooms, a shut-down kitchen, or a flooded floor that sends customers and revenue out the door. We handle commercial plumbing and heating across Long Island with the understanding that speed and reliability are the whole point. The Route 110 corridor in Melville, the Hauppauge Industrial Park, and downtowns throughout Suffolk and Nassau all run on plumbing that has to work.
Our commercial work spans routine and urgent: repairs and installations, water heaters and heating systems, drain and sewer service, fixture and connection work for build-outs, and backflow prevention testing and certification. We keep the documentation businesses need for compliance and coordinate around your hours whenever we can.

Backflow prevention and testing
Many commercial properties are required to have backflow preventers tested and certified on a schedule to protect the public water supply. We test, repair, and certify backflow assemblies and provide the documentation your jurisdiction requires. Staying current keeps you compliant and avoids the scramble of a lapsed certification.
Serving Long Island’s commercial corridors
The Route 110 corporate corridor through Melville, the sprawling Hauppauge Industrial Park, and the retail and restaurant districts across Huntington, Farmingdale, Westbury, Mineola, and beyond generate steady commercial plumbing demand — backflow, grease lines, high-use restrooms, and heating for large spaces. We know these buildings and the pace their businesses need to keep.
Backflow testing and compliance, kept on schedule
Many Long Island commercial properties are required to have backflow preventers tested and certified on a recurring schedule to protect the public water supply. A lapsed certification can mean penalties or service issues — usually because a busy operator simply lost track of the date.
We test, repair, and certify backflow assemblies, provide the documentation your jurisdiction requires, and help you stay ahead of the schedule so a certification never lapses. It's a small piece of proactive compliance that saves a real headache later.
Full-service for Long Island businesses
Commercial work spans more than repairs. We handle gas-line installation, commercial water heaters, and grease-line and high-use drain service — plus backflow testing and certification — so one company keeps the whole building compliant and running.
We serve businesses along the Melville Route 110 corridor and the Hauppauge Industrial Park, scheduling around your hours.

What Affects the Price
We don’t post flat prices, because an honest number depends on your specific situation. For non-emergency work you’ll always get a written scope before we begin. The main factors:
- Scope — routine repair, installation, or full build-out

- Whether work must be scheduled around business hours
- System size and capacity for the facility
