Budget before the site walk
There is no honest flat price for every kitchen. Use planning ranges to screen the scope, then get an itemized quote tied to your actual system.
Public 2026 industry guides commonly place a routine single-hood service around $350–$700, while multi-hood systems, long or vertical ducts and difficult rooftop access can move work toward $800–$2,000 or more. These are planning figures, not a North Charleston bid.
Hood and fan count, duct length and configuration, grease condition, access and cleaning frequency usually move the number most. Night work, wastewater handling and kitchen protection should be explicit in the scope.
Ask whether the price includes the fan, accessible ductwork, filters, protection, cleanup, photos, service label and deficiency notes. A low headline price can exclude the parts that matter during an inspection.
Code summaries are planning guidance. Confirm the current code, interval, permits and reporting requirements with the fire official responsible for the service address.
