As a guideline for the minimum cleaning frequencies you can reference NFPA 96 Table 11.4.

Many things may influence how often your exhaust system should be cleaned including how much you are cooking, what you are cooking, equipment set-up, exhaust system design, building design and insurance requirements.

The average job takes between 3-8hrs depending on the number of systems & amount of ductwork to be cleaned.

Our prices start at $425 for jobs that take up to three hours ($500 for high temp/flame/wok style cooking).  If travel is over 1hr (30min each way), that time is included as part of the job’s cleaning time.

We assign a flat rate that is basically equivalent to $120/hr ($150/hr for high temp/flame/wok style cooking) plus $75 for cleaning supplies. This rate covers supplies & labor with up to 3techs. Our flat rates are only valid for services that are cleaned as recommended and not overdue (15+days for Quarterly & 30+days for Semi Annually). Overdue services may incur additional labor fees to cover the additional supplies and labor required to complete the service.

All hood cleaners do not provide the same level of service. It takes time to clean an exhaust system properly! We clean your roof top fans, all the grease ducts from the roof to the canopy hood, the grease baffle filters and the canopy hood. Some systems have a limited amount of ductwork to be cleaned while others have vertical & horizontal ducts with several bends in them.

We clean the entire  system down to bare metal as stated in the fire code.  . . . shall be cleaned to remove combustible contaminants to a minimum of 50 microns (0.002 in.)  *see grease depth gauge below

Be wary of companies that offer cheap rates. The only way they can afford to do this is to keep labor hours low. The way this is done is to only clean what’s visable. This completely defeats the reason you’re having the exhaust system cleaned.

Yes. The service sticker certifies that your equipment was cleaned by a company that adheres to NFPA Code 96 standards. It includes our company name, lead service tech’s name, date of service, and date the sticker expires (next service date due).

We also offer service reports and before/after pictures if requested.

No. You may stay and watch if you want but it is not required. Customers who do stay are often surprised at how much work is involved with the job. We welcome you to stay and watch because of this.

Feel assured that your restaurant is safe. We carry 1mil liability insurance plus a safety bond.

We clean when your kitchen is not in use.

We work Sunday thru Thursday with Friday & Saturday off.  Most jobs are performed in the evening or overnight hours with the occasional job being done during the day.  Early day time jobs are more difficult for us to schedule since our techs are used to getting home between 4-7am & usually sleep until the afternoon.

NFPA 96 Fire Codes for Hood Grease Filters

Summary: Commercial kitchens are required to use hood filters that are UL listed. When shopping for filters the description should clearly state if they are. Beware of any filters that do not mention it. If they are that means they are Fire Code approved and meet your insurance requirements.

To determine if your existing filters are Fire Code approved you can look on the edge of the filters for a UL or ETL logo stamped into the frame. If there is no UL or ETL stamp they need to be replaced.
