Cleaning02
Our certified technicians deep clean every accessible surface, degreasing hoods, filters, and ducts back to bare metal per NFPA 96 standards.
Certification03
You receive a detailed report with before/after photos and a service certificate, ready for your insurance provider or fire marshal.
Why it matters
Grease buildup isn't just a fire risk in your kitchen on a shared duct, it's everyone's risk.
Starts A Projects-
Fire prevention
Removing grease before it reaches a hazardous thickness is the single most effective way to prevent an exhaust system fire.
-
Shared liability
On a common duct, investigators request records from every connected shop not just the one a fire started in.
-
Insurance evidence
A documented service history is often what decides whether a claim is honoured after any kitchen fire.
-
Compliance record
Councils and certifiers expect current certificates and reports on file not chased down after the fact.
