At National Guardian Enterprises, we take a strategic and customized approach to every facility we service. Our highly trained teams begin by thoroughly evaluating your kitchen exhaust system to understand its unique layout, usage, and fire safety requirements.
We provide tailored service plans and detailed estimates designed to protect your investment, ensure NFPA compliance, and align with your operational schedule—whether you’re running a single location or a multi-site operation.
With our proactive planning, you gain the confidence of knowing your kitchen is protected, compliant, and ready for inspection—without costly disruptions or oversights.
We pioneered key innovations like rotary duct cleaners, rooftop grease containment systems, and photo verification reporting—establishing best practices that have become industry gold standards.
National Guardian Enterprises delivers comprehensive, top-to-bottom exhaust system cleaning for a wide range of commercial environments—including restaurants, hotels, stadiums, corporate cafeterias, shopping malls, catering kitchens, and bakeries.
Whether you're operating a single location or managing multiple facilities, we provide:
• Thorough cleaning of the entire exhaust system—from hoods to fans to ductwork
• Pre- and post-construction consultation for exhaust system planning and compliance
• Detailed service documentation, including before-and-after photos (video available upon request)
• Secure, professional onsite presence—our teams work discreetly, safely, and with full accountability
With National Guardian, you get more than a cleaning service—you get a trusted partner in fire safety and code compliance.
Clean hood filters are essential to maintaining a safe, efficient kitchen exhaust system. Grease-clogged filters are one of the leading causes of accidental flue fires and can severely reduce airflow—leading to smoke buildup, poor ventilation, and premature failure of exhaust fan motors.
While daily cleaning is recommended, National Guardian provides professional on-site hood filter cleaning to support your existing maintenance program. When needed, our team will also measure, source, and install replacement filters to ensure your system operates safely and efficiently.
Exhaust fans often discharge excess grease onto rooftops—creating a serious fire hazard, damaging roofing materials, and voiding manufacturer warranties.
At National Guardian Enterprises, we offer industry-leading rooftop grease containment solutions designed to prevent these risks and extend the life of your exhaust and roofing systems.
If grease buildup is already present, our team will assess the situation and implement a customized containment and cleanup plan tailored to your facility’s needs—ensuring compliance, protection, and peace of mind.Without proper hinging, cleaning and inspections become difficult and can lead to damage to the fan bowl, motor housing, or even your rooftop.
National Guardian installs high-quality, code-compliant exhaust fan hinge kits tailored to your system—improving safety, extending equipment life, and protecting your investment. All at competitive pricing.
According to NFPA 96, all commercial exhaust fans must be equipped with a hinge kit and flexible, weatherproof electrical cable. These components aren’t just required—they’re essential for safe, effective maintenance and long-term system performance.

National Guardian installs high-quality, code-compliant exhaust fan hinge kits tailored to your system—improving safety, extending equipment life, and protecting your investment. All at competitive pricing.
Per NFPA 96, every commercial exhaust fan must be equipped with a 3" x 5" (or 4" circular) access panel on the curvature of the fan bowl. These panels are essential for full access to the fan blades—allowing for thorough cleaning and proper inspection.
Without access panels, grease builds up on the backside of the blades, which can throw the fan off balance, causing vibration, noise, and premature wear to belts and bearings. Over time, this can significantly shorten the lifespan and performance of your exhaust system.
National Guardian installs code-compliant access panels on both exhaust fans and ducts—ensuring safe, complete cleaning and long-term system reliability.
