Chimney cleaning (kitchen hood and exhaust cleaning) removes built‑up grease, smoke residue, and dust from the hood, filters, ducts, and fan to keep kitchens safe and efficient. It is essential in both homes and commercial kitchens to reduce fire risk and improve ventilation and air quality.​

Why chimney cleaning is important

• Fire safety: Grease deposits inside the hood, filters, and exhaust duct are highly flammable and can ignite from open flames or high heat, so regular cleaning greatly lowers the chance of kitchen fires.​

• Better air and efficiency: A clean chimney removes smoke, steam, and odours more effectively, keeping the kitchen more comfortable and helping the fan and motor run smoothly for longer.​

What professional chimney cleaning includes

• Inspection and preparation: Technicians inspect the hood, filters, ductwork, and fan to locate heavy grease buildup and protect nearby equipment and surfaces with covers or tarps before cleaning.​

• Filter and hood cleaning: Filters are removed and soaked in hot water with degreaser, then scrubbed and rinsed; the hood interior and exterior are treated with degreasing agents, pressure‑washed or hand‑scrubbed, and wiped clean.​

• Duct and fan cleaning: Accessible duct sections and the exhaust fan are cleaned using scraping tools and, where needed, high‑pressure washing to remove stubborn grease and debris from internal surfaces.​

Frequency and compliance

Commercial kitchens often require exhaust and chimney cleaning at least quarterly, and heavy‑use operations may need monthly or even more frequent service to meet fire and safety codes such as NFPA 96. Keeping records of each cleaning and inspection helps demonstrate compliance to fire authorities, insurers, and food‑safety inspectors.
