What We Do

Our Grease Ductwork Installation Services in Queens

Custom fabrication and code-compliant installation — keeping Queens restaurant kitchens inspection-ready.

🏗️

Custom Grease Duct Fabrication

We fabricate welded, liquid-tight stainless steel grease ductwork sized to your Queens kitchen's specific exhaust hood CFM — not off-the-shelf sections forced to fit.

🔥

NFPA 96 & FDNY Code Compliance

Every run is designed and installed to NFPA 96 and FDNY requirements, including proper slope, access panels, and clearance to combustibles — the details inspectors check first.

🧱

Fire-Rated Enclosure Installation

When your grease duct run passes through occupied space, we install code-required fire-rated enclosures to protect the building and keep your certificate of occupancy intact.

🏭

Rooftop Termination & Exhaust Fan Coordination

We coordinate duct termination with your rooftop exhaust fan's specifications, ensuring proper draw and eliminating grease buildup at the roof penetration.

🧹

Access Panel Placement for Cleaning

Code requires periodic grease duct cleaning — we place access panels at every required interval so your cleaning contractor can actually reach the full run, not just the ends.

📋

Inspection-Ready Documentation

We provide the installation documentation Queens restaurants need on file for FDNY inspections, insurance requirements, and health department reviews.

LL97 Note: Queens buildings over 25,000 sq ft face escalating carbon penalties starting 2024. Properly sized grease ductwork reduces the load on your exhaust and make-up air fans, cutting the energy needed to keep your kitchen properly ventilated.

From design to inspection-ready

One partner handles every step. Here's how we do it.

Kitchen & hood assessment

A Denair estimator surveys your Queens kitchen's exhaust hood specifications, ceiling and roof routing, and existing ductwork to design a run that meets code and fits the space.

Fabrication & routing design

We design the welded stainless steel duct run, access panel placement, and fire-rated enclosure requirements, confirming the plan against NFPA 96 and FDNY standards before fabrication.

Fixed-price proposal

You receive a clear, itemized quote covering fabrication, installation, and any enclosure work before we start. What we quote is what you pay.

Install & inspection sign-off

Certified installers complete the run, verify slope and clearances, and coordinate final inspection sign-off so your Queens kitchen is fully code-compliant before opening.

Questions we hear every day

Straight answers about grease ductwork installation in Queens — no marketing fluff.

How long does grease ductwork installation take for a Queens restaurant?

A typical single-hood installation takes three to five days depending on run length and whether the duct passes through finished ceilings requiring fire-rated enclosure work. Denair sequences fabrication off-site where possible to minimize on-site time, and we coordinate scheduling around your kitchen's opening timeline so you're not losing service days unnecessarily.

Is Denair's grease ductwork installation code-compliant?

Yes — every installation is designed and installed to NFPA 96 and FDNY requirements, including proper slope, welded liquid-tight seams, clearance to combustibles, and required access panels for cleaning. We coordinate directly with inspectors where needed and provide the documentation Queens restaurants need on file for ongoing compliance reviews.

How does grease ductwork design relate to Local Law 97 compliance?

LL97 caps carbon emissions for Queens buildings over 25,000 sq ft, and undersized or poorly routed grease ductwork forces exhaust and make-up air fans to work harder than necessary, increasing energy consumption. Properly sized, code-compliant ductwork reduces that fan load, contributing to a lower overall HVAC energy footprint for the building.

What does grease ductwork installation cost in Queens?

Cost depends primarily on duct run length, the number of bends and fire-rated enclosure sections required, and rooftop termination complexity. Denair provides a fixed, itemized quote after the kitchen assessment, covering fabrication and installation together so there are no surprise charges once welding begins.

Does Denair coordinate with our exhaust hood and make-up air installer?

Yes — grease ductwork has to work in concert with your exhaust hood's CFM rating and your make-up air unit's supply, so we coordinate directly with those installers (or handle both scopes ourselves) to make sure the whole ventilation system is balanced and code-compliant, not just the ductwork in isolation.
