Extract Fan Cleaning in Corhampton
Extract fan cleaning in Corhampton from ventilation hygiene specialists trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- A fan left out of previous cleans
- A fan coated in grease inside its housing
- A noisy fan that has got louder over time
Multi-site and managed buildings
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
We also work for facilities teams across offices, schools and healthcare across Hampshire. Work can be phased by floor, building or site around the people who use them.
About our extract fan cleaning in Corhampton
A fan never collects grease in a neat, even layer. Heavier deposits on some blades throw the impeller off balance, which brings vibration, noise and extra wear on the bearings and motor. Cleaning the impeller and housing puts that right. The work covers axial fans, centrifugal fans and in-line fans, and common reasons people get in touch are vibration from an unbalanced impeller and weak extraction at the canopy.
Work in a small place like Corhampton starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Part by part
Fan housings and motors
Motors and their electrics are kept dry and treated with care, and the fan is isolated throughout. Grease on and around the motor can trap heat, so the surrounding area is cleaned carefully.
Kitchens with long cooking hours
A fan in a long-hours kitchen runs for most of the day, so grease and wear build up together. Regular cleans help it keep going.
Looking after it afterwards
Good habits slow the build-up between visits. Our tips:
- Note any drop in extraction at the canopy
- Keep the fan on whenever the range is lit
- Keep each photo report with the maintenance log
- Look for grease stains near the discharge
The photo report shows the fan before and after cleaning. It lists what was cleaned and anything we couldn’t reach, along with the recommended next clean date.
Make sure the fan is reachable. A fan that can be reached safely is a fan that gets cleaned, whether it’s on a roof, in a ceiling or on a wall.
What extract fan cleaning looks like in Corhampton
About 57 miles out from central London, Corhampton is part of the South East area we work across. Visits are booked around your hours, evenings and weekends included. Fire safety in Corhampton falls to Hampshire and Isle of Wight Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
A hall kitchen that only cooks for events, whether near Corhampton Church or elsewhere in Corhampton, still needs its extract cleaned, just less often. Historic houses near Corhampton, such as Hinton Ampner House about 4.4 miles north, are a reminder that older buildings with event kitchens can have long, awkward duct routes.

The process
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes a couple of hours per fan, depending on its size and the build-up. We agree a date with you, plan the drive to Corhampton and turn up when the site is quiet.
- First we locate the fan and agree how it’s safely isolated.
- With the fan isolated, the housing is opened.
- Grease is scraped from the impeller blades and the inside of the housing.
- We degrease the fan and housing, taking care around the motor.
- We reassemble, run the fan and photograph the result.
Preparing for the visit
- Name a contact who can let us in at the agreed time
- Let us know when the site is closed or quiet
- Move anything stored near the system

What we are called out for in Corhampton
A greasy fan in Corhampton is fuel at the end of the duct. If grease in the duct catches, the fan and its housing can feed the fire, and a hot, struggling motor does not help.
Common reasons sites call us are:
- An extract fan that vibrates or rattles
- A smell of hot grease from the extract
- A noisy fan that has got louder over time
- A fan coated in grease inside its housing
Term dates shape school work: for a school like Meonstoke Church of England Infant School, an extract clean fits neatly into a half-term or summer break.

Common questions in Corhampton
Can you work in Corhampton outside opening hours?
Yes, nights and weekends are routine for us. The work in Corhampton can fit around your hours. Just ring 0345 646 2711, or email photos with your opening times and we’ll plan around them.
Can school kitchens in Corhampton be cleaned in the holidays?
Yes, holiday work suits schools best. Food Standards Agency records list about 2 schools, colleges and universities with registered kitchens within about a mile and a half of Corhampton. You can phone us on 0345 646 2711, or send details by email with the dates the site is empty.
Do you have insurance?
Yes. We carry full insurance and have been trading since 2009.
Is TR19 cleaning required by law?
No. TR19® itself is not law; it’s a BESA specification. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
How much does extract fan cleaning cost?
It depends on the site, so we quote each one individually. For a quote, call 0345 646 2711 or email us with the site type, opening hours and a few pictures.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before any work starts, and waste is contained as we go. At the end, the area is cleaned down.
Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. The report from each visit recommends the next date.
What staff can safely do
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
What affects the cost of extract fan cleaning
You’ll get a fixed price before work begins. It’s based on:
- What state the system is in
- Parking and loading at the site
- The number of sites or systems
- Whether it’s a one-off visit or part of a schedule
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.
What to send for a quote
To help us quote quickly, please include:
- The times we could work without disrupting the site
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The site address and the type of premises
We don’t publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, and then give you a fixed quote. To get going, give us a ring on 0345 646 2711 or email us.
