Specialized offerings:
- Build‑outs & Tenant Improvements – We coordinate drawings, submittals, and inspections with general contractors, architects, and NYC DOB field inspectors to keep your critical path intact.
- Backflow Prevention – Selection, installation, annual testing, and electronic filing of Form GEN‑215 with DEP. We are certified testers; you never need a second subcontractor.
- Grease‑Trap Programs – Right‑sized indoor or outdoor interceptors, bimonthly clean‑outs, effluent sampling, and digital maintenance logs that stand up to DOH audits.
Coordinated Build‑Outs: One Call, Fewer Headaches
Commercial schedules are unforgiving. We plug seamlessly into GC project‑management software, attend weekly coordination meetings, and provide stamped shop drawings within 48 hours of scope finalization. By staying ahead of RFIs and DOB progress inspections, we reduce costly re‑mobilizations and let other trades hit their marks.
Regulatory Assurance & Certifications
NYC plumbing isn’t just pipes and valves; it’s paperwork. We maintain active:
- NYC LMP license & insurance certificates
- DEP backflow tester certification
- EPA Renovation, Repair & Painting (RRP) lead‑safe certification
- OSHA 30 and Site Safety Training cards for all field supervisors
Our office files permits, pulls after‑hours variances, and tracks inspection sign‑offs in real time, so you never miss a CO or DOH deadline.
Grease‑Trap Installation & Maintenance
Restaurants that ignore their interceptors face surprise shutdowns, foul odors, and five‑figure fines. We calculate peak flow, size the right passive or automatic grease‑removal unit, and establish a preventive cleaning cadence. Every service visit includes digital before‑and‑after photos and a manifest accepted by DEP and DOH inspectors.

- Lower Operating Costs: Clean heat‑exchange surfaces and leak‑free fixtures use less fuel and water.
- Longer Asset Life: Boilers, pumps, and valves perform better when flushed, lubed, and properly balanced.
- Regulatory Peace of Mind: Up‑to‑date logs satisfy DOB, DEP, and DOH inspectors.
- Predictable Budgeting: Small scheduled costs replace large surprise repairs.
