It will cost between $400 – $600 to have a restaurant kitchen exhaust hood professionally cleaned. The price is dependent on how tall the building is, the size of the hood and how much grease is built up. Most often the service is billed based on the hours of labor spent, so if the hood is extremely dirty, expect to pay more. To learn more, call one of the team members at Facilitec Southwest.
