(SERVICE OVERVIEW)

Exhaust Duct Repair & Access Panel Services

A commercial kitchen exhaust duct must be cleaned to bare metal regularly. However, many duct systems contain long vertical or horizontal runs that lack access points. Without access panels, grease accumulates in hidden duct sections, creating a severe, undetectable fire hazard inside the building structure.

NFPA 96 codes require liquid-tight access panels at every duct turn and every 12 feet of horizontal run. Crossaire specializes in retrofitting UL-listed, fire-rated access panels into existing ductwork. We also repair duct leaks, weld duct seams, and ensure your entire exhaust path is sealed and code-compliant.

(CRITICAL HYGIENE & SAFETY)

Why Access Panels and Duct Repairs are Essential

Inaccessible ducts cannot be properly cleaned and violate fire safety codes. Here is why duct upgrades are vital:

Access for Proper Cleaning

Ducts cannot be degreased if technicians cannot reach them. Installing access panels allows deep cleaning of hidden duct areas.

Prevent Grease Leakage

Grease escaping from duct leaks can soak building walls, ceilings, and insulation. If a fire starts, these grease deposits will ignite.

NFPA 96 Compliance

Fire codes mandate the spacing and design of exhaust duct access panels. Installing approved panels prevents code violations and fines.

(SYSTEM WARNING SIGNS)

Signs Your Ducts Need Repair or Access Panels

Audit your exhaust ductwork regularly. If you notice any of these warning signs, schedule duct repairs immediately:

Uncleaned Duct Sections

If cleaners tell you they cannot access parts of your duct run, you need access panels installed.

Grease Stains on Ceilings

Oily spots or grease stains appearing on ceiling tiles indicate a leaking exhaust duct above.

Rancid Oil Odors

Burnt grease smells lingering inside walls or ceilings point to duct leaks and air bypass.

Failed Inspector Audits

Fire marshals or mechanical inspectors flagging your duct runs for lacking access doors.

Duct Corrosion or Holes

Physical holes, heavy rust, or split seams in the duct metal allow heat and grease to escape.

Draft leaks

Suction whistling or air leaks along duct seams indicate weak joints requiring sealing.

(HOW WE WORK)

Our Step-by-Step Process

We employ a meticulous, structured process to ensure safety, efficiency, and zero mess left behind:

01

Duct System Mapping

We trace your entire duct run, identify hidden sections in ceilings, and mark where access doors are required by code.

02

Duct Cutout Preparation

We cover the kitchen workspace under the duct in thick plastic and mark the exact opening size on the duct.

03

Opening Cutout

Using specialized cutting tools, we cut a clean opening into the ductwork, removing the metal piece.

04

Access Panel Mount

We place a UL-listed, fire-rated access panel frame into the opening, using high-temperature silicone seals.

05

Fastener Security

We clamp and bolt the access door tightly to the duct frame, ensuring a liquid-tight seal that holds under pressure.

06

Duct Leak Repairs

We inspect surrounding joints and apply high-temp sealant or weld weak seams to eliminate air leaks.

07

Verification Check

We verify the door opens and seals securely, clean the workspace, and log the new access points.

Frequently Asked Questions

Got questions about Kitchen Exhaust Duct Repair & Access Panel Installation schedules, compliance, or logistics? Find detailed answers below:

Exhaust ducts must be cleaned to bare metal. Grease accumulates inside vertical and horizontal runs. Without access panels, technicians cannot reach these sections, violating fire safety codes.
NFPA 96 requires access panels at every turn, change of duct direction, and every 12 feet of horizontal run. Vertical ducts require access at the top and bottom of the run.
We cut a hole in the duct wall, clean the metal edges, insert a UL-listed access door assembly with high-temperature gaskets, and clamp it securely. The panel is sealed liquid-tight.
Common signs include oil dripping from ceiling tiles, greasy stains on walls, grease odors inside structural wall cavities, and draft leaks along duct joints.
Yes. Grease leaking from a duct can coat drywalls, timber framing, and electrical wires inside walls. If a fire starts in the hood, it can spread through these grease deposits.
Yes. We install heavy-gauge, UL-listed, fire-rated steel access panels. They feature high-temperature silicone gaskets that ensure a liquid-tight seal to prevent grease leaks.
