Commercial hood & exhaust cleaning in the DMV
Grease-laden exhaust systems are the leading cause of restaurant fires — and the first thing a fire marshal checks. NEXUS BUILD provides NFPA 96 hood and exhaust cleaning for commercial kitchens across DC, Maryland, and Virginia, from single hoods to multi-unit portfolios.
Because we're a commercial contractor, not just a cleaning crew, we also catch what cleanings usually miss: failing fan bearings, damaged ductwork, missing access panels, and hood systems that no longer meet code. You get a clean system and a report on its actual condition.
Hood & exhaust services
- NFPA 96 cleaning of hoods, filters, ducts, and rooftop fans
- Before/after photo documentation and service certificates for insurers and fire marshals

- Emergency degreasing after inspections or fire-marshal citations
Why cleanliness certificates matter
Insurance carriers and fire marshals expect proof of cleaning to a set schedule based on cooking volume. We document every service with photos and a certificate, and we track your interval so the next cleaning is scheduled before it's overdue.
Frequently asked questions
How often does my hood system need cleaning?
NFPA 96 ties frequency to cooking type: solid-fuel cooking monthly, high-volume operations quarterly, moderate volume semi-annually, and low-volume annually. We'll assess your line and put you on the right interval.
Do you clean the whole system or just the hood?
The whole system — hood, filters, ductwork to the roof, and the exhaust fan. Hood-only cleanings leave grease in the duct, which is where fires actually spread.
Can you fix problems you find during a cleaning?
Yes — that's the advantage of a contractor doing the work. Fan motors, belts, duct damage, and access-panel installs can usually be handled by the same team, often on the same visit.
