How Long Does Hood Cleaning Take?

There is no single answer. A hood cleaning can be a short visit for one small hood, or a longer job for a large kitchen with several hoods and a long duct run. This guide explains what changes the time and how to plan around it.

How long does a kitchen hood cleaning take?

It depends on the size and condition of the system. Any provider's honest answer should come after an inspection, because the same kitchen can take very different amounts of time depending on how much grease has built up and how easy the system is to reach.

At HoodEx, we give you a time estimate after inspecting your system, so the plan matches what is actually there.

What makes a hood cleaning take longer?

• The number of hoods and exhaust fans in the kitchen
• The length and layout of the duct run
• How much grease has built up, which depends on how long it has been since the last clean
• Access: how easily the duct access panels and the roof or ceiling void are reached
• Whether the system has an ESP unit that also needs cleaning
• Whether you want the hood only or the complete system cleaned

Does cleaning only the hood take less time?

Yes. A hood-only clean covers fewer parts than a complete system clean, so it takes less time. The trade-off is that the duct and fan are left as they were, and that is where much of the grease collects. Read the difference between kitchen exhaust cleaning and hood cleaning before you choose.

The complete exhaust system cleaning service covers the hood, filters, duct, ESP unit where fitted, and the fan in one coordinated visit. Duct cleaning on its own, with a rotary brush machine, can take longer than the hood because the duct is longer and harder to reach. See exhaust duct cleaning for how it works.

Can the kitchen keep working during the cleaning?

The hood and exhaust system are switched off while they are cleaned, so cooking beneath them has to stop. If your kitchen cannot close for long, tell the provider when you book so the work can be planned around it.

When is the best time to book?

Outside your busiest hours, so service is not interrupted. Many kitchens choose a time after closing or on a quiet day. Where possible, we arrange the work around your kitchen's operating hours.

How can you prepare to keep the visit short?

1. Clear space around the hood and the equipment below it.
2. Make sure the duct access panels are reachable.
3. Arrange access to the roof or ceiling void where the exhaust fan sits, including any building permissions.
4. Tell the provider if the system has an ESP unit.
5. Confirm who will let the team in and at what time.

What should you ask when you book?

• How long do you expect the cleaning to take for my system?
• Will it be done in one visit?
• Can you work outside our operating hours?
• What do you need from us before you arrive?
