About Duct Doctor

Kitchen extract and ventilation hygiene since 2009

Duct Doctor has cleaned commercial kitchen extract systems and ventilation ductwork since 2009. We work for restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and shops, food producers and leisure sites across Greater London and the South East.

Our approach is simple, and it’s where the name comes from. We diagnose the system first, from photos or a site survey, with grease readings where they’re needed. We treat it: a thorough clean of every part we can reach, from canopy to fan. Then we sign it off with a clean bill of health: a certificate and a photo report that shows exactly what was done.

What we do

• Kitchen extract cleaning to TR19® Grease, including canopies, ductwork, risers, fans and filters
• Fire damper drop testing, smoke damper testing and damper repairs
• Ventilation cleaning to TR19® Air and air handling unit cleaning
• Grease thickness testing, surveys, post-clean verification and TR19 audits
• Extract fan repair and replacement, access panels and grease filter exchange
• Commercial kitchen deep cleaning and grease trap cleaning
• Laundry extract cleaning, LEV testing and odour control maintenance

How we work

Kitchens can’t stop for a clean, so we work when they’re closed: evenings, overnight, weekends and school holidays. There’s a 24/7 line for emergencies. Every job starts with a fixed quote, usually within one working day, and ends with paperwork your insurer, fire officer and environmental health officer can rely on.

Accreditations

We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured. More about our accreditations.
