Range Hood Cleaning in Loudoun County

The commercial range hood is the entry point of your kitchen’s exhaust system — the component closest to the cooking surface where grease-laden vapors are first captured. Over weeks and months of cooking, grease accumulates on the filter media, the baffle configuration, the plenum interior, and the grease collection trough before being drawn further into the duct system. A proper NFPA 96 cleaning starts at the range hood canopy and follows the grease path all the way through the duct to the rooftop exhaust fan — leaving the entire system clean, documented, and compliant.

Loudoun County’s restaurant market has expanded dramatically with the county’s residential growth over the past decade. From the high-density mixed-use dining of One Loudoun and the Ashburn Metro corridor to Leesburg’s historic downtown restaurant scene, Lansdowne’s hotel and resort dining, and the newer commercial corridors of Brambleton and South Riding, Loudoun County’s restaurants span the full spectrum of volume, cuisine type, and grease output. The Loudoun County Department of Fire, Rescue, and Emergency Management (DFREM) enforces NFPA 96 through annual commercial fire inspections throughout Loudoun County’s unincorporated communities, and the Town of Leesburg conducts its own inspections within town limits.

What a Complete Range Hood Cleaning Includes

Range Hood Canopy

Grease filters are removed and hot-water pressure washed to remove accumulated grease. The canopy interior — ceiling, walls, and seams — is cleaned to bare metal. The plenum chamber above the filters is thoroughly cleaned. Baffle configurations and filter retaining channels are cleaned and inspected. The grease collection trough is emptied and cleaned. All interior canopy components are restored to clean metal surfaces before filter reinstallation.

Grease Duct System

The grease duct from the hood collar through all horizontal runs, vertical risers, and any offsets to the rooftop penetration is hot-pressure cleaned at each accessible segment. NFPA 96 Chapter 12 requires cleaning of the full duct interior — not just the sections easily visible from access panels. We open all access panels, clean each duct segment, verify cleaning quality photographically, and reseal all access panels after cleaning. Never partial duct cleaning — every inch of the duct interior is cleaned.

Rooftop Exhaust Fan

The rooftop exhaust fan is the terminal accumulation point for airborne grease that passes through the duct system. Fan blades, the fan housing interior, the grease collection basin, and the fan drain are all fully cleaned on every service visit. The hinge arm, latch hardware, and fan access door are inspected for proper function. Roof surface contamination from grease overflow is noted in our field report. Rooftop fan condition photos are included in the documentation package delivered after service.

Documentation & Certification

Loudoun County DFREM-compliant NFPA 96 Certificate of Cleaning, field inspection report, and before-and-after photo set are delivered digitally the same night as service. The certificate identifies the technician, certification number, equipment cleaned, service date, and next service due date per NFPA 96 frequency requirements. Any deficiencies observed during cleaning (damaged filters, access panel issues, fan bearing wear) are documented in the field report with recommended corrective actions.

Frequently Asked Questions — Loudoun County

Does Loudoun County DFREM check hood cleaning certificates during annual inspections?

Yes. Loudoun County DFREM annual commercial fire inspections include a review of NFPA 96 hood cleaning records. Restaurants without a current certificate — or with a certificate more than 12 months old (or beyond the required interval for their cooking equipment type) — receive a written correction notice with a 30-day compliance deadline. Restaurants in the Town of Leesburg are inspected by Leesburg’s own fire inspection program. Both DFREM and Leesburg’s inspectors accept our NFPA 96-compliant certificate format without exception.

My restaurant is in a newer Ashburn or Brambleton strip center — do the same requirements apply?

Yes — NFPA 96 requirements apply to all commercial kitchens regardless of building age. Newer construction in Ashburn, Brambleton, South Riding, and the Route 50 commercial corridor typically has well-designed exhaust systems with properly installed duct access panels, which can make the cleaning process more straightforward. However, the NFPA 96 cleaning frequency requirements are determined by cooking equipment type, not building vintage. Call (571) 556-1700 to schedule service for your Loudoun County location.
