Kitchen Exhaust

This is one of the most critical areas for fire safety. Grease-laden vapors travel through the exhaust system and solidify on the interior surfaces of the ductwork, creating a highly flammable fuel load. Because ducts are typically concealed above ceilings and behind walls, a fire inside an uncleaned duct can spread quickly through the building structure before it is detected. Regular cleaning of the entire duct system by qualified personnel, at frequencies based on cooking type and volume, is required under NFPA 96 to reduce this severe fire risk.

Exhaust fans pull grease‑laden air through the entire kitchen exhaust system and discharge it outdoors. When grease builds up on the fan blades and housing, the fan can become imbalanced, reducing airflow, increasing noise and vibration, and accelerating wear on bearings and motors. Grease accumulation also creates a significant fire hazard at the fan and on nearby roof surfaces, can damage roofing materials, and may even void roof warranties if not properly contained and maintained.

Baffle filters are the metal grease filters installed inside commercial kitchen hood systems. They are the primary line of defense, designed to trap large grease particles before they enter the rest of the exhaust system.

Over time, these filters become clogged with grease, which restricts airflow, forces exhaust fans to work harder, and reduces the system’s ability to remove smoke and heat effectively. Dirty baffle filters also create a significant fire risk, as a flame from the cooktop can easily ignite the accumulated grease.

Pronto offers a baffle filter exchange program that keeps kitchens safer and systems running efficiently. Instead of simply cleaning and reinstalling the same heavily loaded filters, Pronto coordinates regular exchanges with clean, compliant baffle filters through trusted partners, helping maintain proper airflow, reduce fire risk, and support ongoing code compliance with minimal downtime for the kitchen.

Pronto MS coordinates rooftop grease containment services to protect roofs, reduce fire risk, and support NFPA 96 compliance for commercial kitchens. Our certified partners install, maintain, and service rooftop grease containment systems that capture fats, oils, and grease discharged from exhaust fans before they can spread across the roof surface.

Grease containment systems are installed at the rooftop exhaust fan to collect residual grease and oils, preventing them from soaking into roofing membranes, entering stormwater systems, or creating slip and fire hazards on the roof. By stopping grease at the source, these systems help facility owners avoid premature roof failure, costly structural repairs, and potential environmental violations.

Over time, uncontained or past grease discharge can stain and deteriorate roofing materials, attract pests, and create unsafe walking conditions for anyone servicing rooftop equipment. Pronto MS coordinates professional rooftop cleaning and power washing to remove accumulated grease and residues around exhaust fans, curbs, and drainage paths, helping restore a safer, cleaner roof surface.

These services focus on carefully cleaning affected areas while protecting the roof membrane and preventing contaminated wash water from entering storm drains or municipal systems, in line with best management practices. Regular rooftop cleaning supports longer roof life, better safety for technicians, and a more compliant exhaust system from cookline to fan

Pronto MS manages the selection and installation of rooftop grease containment systems—such as grease boxes, absorbent containment media, and perimeter barrier units—matched to each kitchen’s exhaust volume and equipment. These systems are designed to capture grease discharges while allowing rainwater to drain, protecting both the roof membrane and the surrounding environment.

Our service includes inspecting existing rooftop grease containment components (grease boxes, absorbent pillows, pads, and media), replacing saturated materials, and ensuring collected grease is properly contained and disposed of according to local environmental and wastewater regulations. By keeping containment systems in good working order and documenting service, Pronto MS helps facilities stay ahead of roof damage, environmental issues, and the heightened fire risk associated with grease-laden roofs and exhaust systems.

Pronto MS coordinates accessory installations and repairs to keep commercial kitchen exhaust systems safer, easier to service, and compliant with current codes. This includes adding, upgrading, and maintaining key components that improve access, drainage, and overall system performance.

Hinge Kits

• Hinge kits are installed on rooftop exhaust fans to allow the fan to be safely tilted back for cleaning and inspection, without stressing the ductwork or electrical connections. Properly installed hinge kits make it easier for technicians to access the fan and duct, reduce damage to the fan base and roof, and support code-compliant exhaust cleaning.

Grease Containment Accessories

• Pronto MS also manages the installation and replacement of grease containment accessories such as absorbent pads, replacement media, splash guards, and diversion trays. These accessories help keep grease inside the containment system, protect roofing materials, and reduce slip, fire, and environmental hazards around the fan.

Electrical Whips

• Electrical whips provide flexible, code-compliant electrical connections to rooftop exhaust fans and related equipment. By upgrading or replacing damaged or outdated whips, Pronto MS helps ensure fans can be safely disconnected for service, remain properly grounded, and continue to operate reliably after cleaning or maintenance.

Full-Access Duct Access Panels

• Full-access duct access panels are installed along grease ducts to give technicians direct entry points for cleaning and inspection. Adding or upgrading access panels improves the ability to thoroughly clean grease-laden duct interiors, supports NFPA 96 requirements, and reduces hidden fire risk inside the ductwork.

Other Exhaust System Accessories

• In addition to these core components, Pronto MS can coordinate installation and repair of other exhaust system accessories such as drain pans, fan curb adapters, weather hoods, and protective guards. These upgrades help extend equipment life, simplify maintenance, and provide a more complete, safe, and serviceable exhaust system from the cookline to the rooftop.

Pronto MS offers coordinated kitchen tile cleaning services to keep floors, walls, and grout lines free from built-up grease and soil. Deep cleaning of high-traffic and cookline areas improves safety by reducing slip hazards and supports a cleaner, more professional kitchen environment.

Working through trusted providers, we schedule tile and grout cleaning during off-peak hours, helping kitchens maintain better hygiene, appearance, and inspection readiness without impacting service.

Pronto MS also manages wall and kitchen surface cleaning to address splatter, film, and residue that accumulate on vertical and hard-to-reach areas. Regular cleaning of walls, backsplashes, and surrounding kitchen surfaces supports better overall sanitation and helps protect finishes from long-term grease damage.

By bundling wall and surface cleaning with exhaust and rooftop services, Pronto MS helps facilities maintain a cleaner, safer kitchen environment from floor to ceiling with centralized coordination and documentation.
