Access Panel Installation

You can't clean what you can't reach. NFPA 96 requires that every part of the exhaust duct be accessible for inspection and cleaning. That means access panels at the right intervals — typically every 12 feet on horizontal runs, at every change in direction, at the base of vertical risers, and near the fan. Without proper access, you can't clean the duct properly, you can't inspect it for damage or excessive grease buildup, and you're not in compliance with fire code.

A lot of older systems don't have enough access panels, or they have panels that are in the wrong spots or too small to actually get a tool through. Some systems have no panels at all above the plenum. When that's the case, the cleaning crew can only reach what they can access from the hood opening and the rooftop fan. The middle section of the duct — often the longest run — stays dirty. That's where grease builds up fastest, and it's the section most likely to ignite in a fire.

“You can't clean what you can't reach — NFPA 96 requires that every part of the exhaust duct be accessible for inspection and cleaning.”

We fabricate and install code-compliant access panels. We measure and mark the locations based on NFPA 96 requirements, cut the duct, frame the opening if needed, and install a hinged or bolted panel with a gasket to prevent air leaks. Panels are typically 12x12 or 12x18 inches depending on the duct size. We match the duct material — usually galvanized steel or stainless steel. The panel is secured with bolts or rivets and gasketed so it doesn't leak air or allow grease vapor to escape.

This is a separate service from cleaning. If we identify missing panels during an inspection or a cleaning, we'll note it in the report and provide a quote. Installation usually takes a few hours depending on how many panels are needed and how accessible the duct is. Some ductwork is inside soffits or above ceilings, which adds time. If the duct runs through multiple floors or tight spaces, we may need to coordinate with your maintenance staff or landlord to get access.

Once the panels are in, the system can be cleaned and inspected properly going forward. You'll be in compliance with NFPA 96, and your cleaning intervals will be more effective because we can reach the entire duct. If you've been told by the fire marshal that you need access panels installed, or if your last cleaning report noted missing panels, call Kendall & Nicole at (903) 571-6744 and we'll schedule a site visit to assess the system and provide a quote.
