Our Kitchen Grease Exhaust Services in Long Island City
Certified cleaning, repair, and compliance work — keeping Long Island City's commercial kitchens running safely and up to code.
Grease Exhaust Hood Cleaning & Inspection
NFPA 96-compliant cleaning of hoods, filters, and ductwork on a schedule matched to your kitchen's cooking volume, with documentation for your insurer and fire marshal.
Ductwork Repair & Replacement
Grease ductwork takes a beating from heat and buildup. We repair seams, welds, and access panels — or replace sections outright when corrosion compromises safety.
Make-Up Air Balancing
Properly balanced make-up air keeps your kitchen from running negative pressure, which pulls in outside air, strains exhaust fans, and drives up energy costs.
Fire Suppression Coordination
We coordinate hood cleaning and ductwork service around your Ansul fire suppression system's inspection schedule, keeping your kitchen's full safety system aligned.
FDNY & LL97 Compliance
Commercial kitchens face both FDNY exhaust code requirements and, for larger Long Island City buildings, Local Law 97 carbon exposure — we help you manage both from one contractor.
Exhaust Fan Repair & Replacement
Rooftop kitchen exhaust fans run hard and get dirty fast. We repair belts, motors, and bearings, or replace fans that can no longer keep up with your kitchen's demand.
From code violation risk to passed inspection
One partner handles every step. Here's how we keep your kitchen compliant.
Kitchen & exhaust system survey
A certified technician inspects your hood, ductwork, fans, and make-up air system, documenting grease buildup and any code deficiencies.
Cleaning & service schedule design
We build a cleaning frequency around your cooking volume and equipment type — a high-volume fryer line needs more frequent service than a light-prep kitchen.
Fixed-price service proposal
A clear, itemized quote for cleaning, repair, or replacement work — approved before any work begins, with no surprise add-ons.
Certified service & documentation
Work is completed to NFPA 96 standards, with dated certification stickers and reports left on file for your fire marshal, insurer, or landlord.
