How we handle extract fan cleaning in The Sands
Duct Doctor has been cleaning kitchen extract fans since 2009. As a BESCA Vent Hygiene Elite member, we clean to BESA TR19® Grease, and we’re fully insured, with CHAS, SafeContractor and ISO 9001. If you’re dealing with a fan that hums, whines or rumbles and a fan that has never been cleaned, we can help, from roof-mounted fans, in-line fans and discharge points onwards.
Work in a small place like The Sands starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
Nothing is signed off by word of mouth: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

What the work involves, part by part
Fan housings and motors
The housing around the impeller catches grease flung off the blades. We clean it along with the blades.
Roof-mounted fans
Roof fans sit at the top of the riser. They’re cleaned where safe access allows, with any limits noted.
What we’re called out for in The Sands
A greasy fan in The Sands is fuel at the end of the duct. If grease in the duct catches, the fan and its housing can feed the fire and an overworked motor runs hotter.
Clients typically contact us after spotting one of these:
- Vibration from an unbalanced impeller
- Rough running from the extract fan
- Hot, greasy smells near the fan
- A fan left out of previous cleans
If you look after a school kitchen, at a school such as South Farnham School or anywhere near The Sands, the holidays are the usual time for a TR19® clean.
What to look for in a quote

Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
What affects the cost of extract fan cleaning
A fixed price needs a few facts first. We look at:
- When the work can happen, such as evenings, overnight or weekends
- Access, including roofs, risers and ceiling voids
- The condition we find in the survey
- Parking and loading at the site
What you pay reflects the actual work. That’s why we survey first, from photos or on site, and the price is agreed before work begins.
Asking for a quote
A few details help us quote accurately. With your enquiry, please include:
- Photos showing the whole system and its surroundings
- Detail shots of panels, filters and grilles
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The times we could work without disrupting the site
To get a fixed quote, call us on 0345 646 2711 or drop us a line with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. We normally come back within one working day.
For landlords and multi-site operators
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
The process
We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes a few hours where there are several fans or heavy deposits. Seeing the system in pictures first means the trip to The Sands can be planned properly.
- We find the fan and check how it’s reached and how it’s isolated.
- Power to the fan is isolated before anyone touches it.
- We remove the grease from the blades, impeller and casing.
- The fan and its surrounds are degreased, keeping clear of the motor’s electrics.
- It’s closed up, run and checked, and photos go into your report.
Getting ready for the visit
- Find the previous report, if there is one
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Make sure equipment near the work can be switched off and left to cool
Ask for a quote
We don’t publish a price list, because every site is different. We look at your system first, from pictures or on a visit, and then send you a fixed quote. To get going, ring 0345 646 2711, or send details by email.
Advice
Grease, kitchens and The Sands
The FSA’s food hygiene register includes about 5 bars, pubs and nightclubs across The Sands and its immediate surroundings (about a mile and a half). Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Fire safety in The Sands falls to Surrey Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. It’s Guildford council that sends environmental health officers to food businesses in The Sands. Extraction counts as kitchen equipment, so its condition can come up on the day. A dated certificate in the maintenance file answers the question before it’s asked.
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to The Sands is Milford Hospital, about 5.7 miles south-east. Volunteers running a hall kitchen near The Church of the Good Shepherd, or anywhere in The Sands, may not know when the extract was last cleaned, and a grease test settles it.
The Sands is about 2 miles east of Farnham, in Surrey. We carry out extract fan cleaning for commercial premises of every kind in The Sands and the rest of Surrey. The Sands is one of 395 places in Surrey where we work for commercial clients. There’s also a page for Guildford, roughly 8 miles from The Sands.
Work in GU10 is surveyed, quoted and booked the same way as anywhere else. You will find streets such as The Green, Binton Lane and Botany Hill, and we cover them all for extract fan cleaning. We also cover the places around The Sands: Runfold (1 mile west), Sandy Cross (1 mile north), Compton (1 mile west), Seale (1 mile north-east) and Tongham (2 miles north).

Landmarks near The Sands
We work in commercial kitchens and buildings around Crooksbury Hill and the streets around them. The nearest railway station is Farnham station, roughly 2.3 miles west. Nearby you will also find Milford Hospital (5.7 miles south-east) and Farnham Castle (2.8 miles west). The countryside around The Sands includes Culverswell Hill and Runfold Wood.
What happens if it’s left?
Grease on a roof fan can also escape outside. That stains surfaces and can add to the fire risk outside the building, which is one more reason to keep it clean. In a small place like The Sands, a system that fails can take a site out of use.
We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, call 0345 646 2711 or send us an email, and we will talk you through it.

FAQs for The Sands
Do you work overnight in The Sands?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Let us know the hours you’re closed and we’ll book within them.
Who enforces fire safety at workplaces in The Sands?
It’s Surrey Fire and Rescue Service, which covers The Sands. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Is there a survey before the work?
Yes. Every job is surveyed first, from your photos and details, or with a visit where needed. A fixed quote follows.
Are you fully insured?
Yes. Full insurance covers our work and have been trading since 2009.
Why is my extract fan noisy?
A common cause is grease. Grease collects unevenly and unbalances the impeller, causing vibration and noise. If cleaning does not, the bearings or motor may need attention.
Do you offer emergency callouts?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we will talk you through the next steps.
How do you protect the area?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
What should I send you?
Where the site is, what it is and when it’s open, plus photos of the system and your last certificate or report if you have one.
