Gravesend: your questions answered
Can the work in Gravesend be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Just phone us on 0345 646 2711, or send details by email with your opening times and we will plan around them.
What if my kitchen extract fan stops in Gravesend at night?
Our emergency line runs 24/7, and Gravesend is within the area we cover. Use 0345 646 2711, our emergency number, at any time. Tell us where the fan is and how to reach it.
What should go in our maintenance log?
Visit reports, certificates and your in-house cleaning logs. Insurers, fire officers and EHOs may all ask to see them, so keep them together and easy to find.
Do we need to close while you work?
Not normally. We work when the area is out of use, such as evenings, overnight, early mornings or weekends, so the site can carry on as normal.
Are you fully insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
How much time does a fan repair need?
A typical repair takes an hour or two to diagnose, then longer if parts or a new fan are needed including running the fan afterwards. We plan the work around your service wherever we can.
Who is the responsible person?
It depends on the building. Under the Fire Safety Order 2005, it’s the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
Will you tell us when the next visit is due?
Yes. The recommended date is on the report. For kitchen extracts, BESA’s minimum intervals run from every 3 months for heavy use to every 12 months for light use, and fire dampers need testing at least once a year.
Extract fan repair for kitchens and businesses in Gravesend
Kitchens in Gravesend call us about extract fans and motors that are noisy, slow or dead, we find the cause and quote a fixed price to repair or replace it. When the fan gives up mid-service, our 24/7 emergency line is there. The work covers belts and pulleys, roof and wall fans and bearings, and the jobs we see most are a fan that won’t start at all and a worn or slipping fan belt.
In a village or hamlet like Gravesend, the kitchens with extract fans are few, wherever there are any. When one fails, the cooking stops, and our 24/7 emergency line covers rural addresses too.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What the work involves, part by part
Impellers and housings
The impeller is the bladed wheel that moves the air. Grease deposits unbalance it and cause vibration.
Motors and bearings
If the motor runs hot or keeps tripping, something’s wrong. It may be straining against blocked filters or ducts, or the motor itself may be failing.
Extract fans in Gravesend
Environmental health officers from East Hertfordshire council inspect food businesses in Gravesend. Under food hygiene rules, a kitchen needs suitable and sufficient ventilation. So a failed fan is worth fixing before the next service, not the next month. At about 29 miles from central London, Gravesend sits well inside the area we cover. Visits are booked around your hours, evenings and weekends included.
If you run a school kitchen, at a school such as Albury Church of England Voluntary Aided Primary School or nearby, a fan that is getting noisy is best repaired in the holidays before it fails in term. If you look after a church or hall kitchen near Church of St Mary, or anywhere in Gravesend, test the extract fan before a big event rather than on the day.

What affects the cost of extract fan repair
We do not publish a price list, because sites vary so much. What we look at:
- The size of the system
- Travel, parking and unloading
- One-off work versus a regular cycle
- What state the system is in
What you pay depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before any work starts, so there are no surprises.
What we need to know
Many jobs can be priced from photos and some basics. Useful things to send:
- Photos showing the whole system and its surroundings
- Any symptoms, from odd noises to smells or leaks
- The roof, plant room or outside wall the system runs to
- The times we could work without disrupting the site
Quotes are quick. Send a few details and photos, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Multi-site and managed buildings
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
Between visits
A little care between visits keeps the system in better shape. We recommend:
- Make sure every filter is in place and clean
- Never run the extract with filters missing
- Keep the fan on a planned cleaning cycle
- Do not turn the fan down to hide a noise
Listen to the fan over the next few weeks. A new noise or vibration is worth reporting early rather than waiting for it to fail.
Small faults, like a worn belt, are quick to fix. Ignored, they can lead to bigger failures, so it’s worth acting early.
What a clean will not put right
Some problems need a different service or another trade:
- Gas interlock faults that a Gas Safe registered engineer must deal with
- Cooking smells reaching neighbours, which may need odour control
- Wiring and supply faults beyond the fan itself
If in doubt, ring 0345 646 2711 or send us an email and we will say what we think before you book.
Parts of the system we cover
- Roof and wall fans
- Belts and pulleys
- Bearings
- Fan housings
- Fan motors
- Kitchen extract fans
What we do, step by step
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. The middle part takes longest, and that takes part of a day for most faults, with a return visit if parts have to be ordered. For a village or hamlet like Gravesend, tell us about narrow lanes, gates and parking when you book.
- We agree a time to attend, out of hours if needed.
- We isolate the extract and open the fan housing.
- Bearings, drive, impeller, motor and mounts are inspected.
- You hear whether repair or replacement makes sense, with a fixed quote.
- The fan is repaired or replaced, then checked running.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Clear the space around the work
- Let us know how we reach the system, including roofs, risers and plant rooms
How to get a quote
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

In-house cleaning or a specialist?
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
