About our extract fan repair in Danbury
Grease and fans do not mix. Deposits on the impeller throw it out of balance, which shakes the bearings and mountings. So when we repair extract fan, we look at the grease too and can arrange a TR19® clean of the whole system at the same time. If you’re dealing with a fan worn beyond sensible repair and an overheating extract motor, we can put it right.
In a place like Danbury, extract fans are often older units on a wall or roof. An older fan that fails may be better replaced than repaired, and we’ll explain the options.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What staff can safely do
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
What affects the cost of extract fan repair
We quote each job individually. This is what makes a difference:
- Travel, parking and unloading
- When the work can happen, such as evenings, overnight or weekends
- The condition we find in the survey
- Whether it’s a one-off visit or part of a schedule
We do not list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we’ll talk you through it.
Asking for a quote
We can often survey from pictures. Try to include:
- The roof, plant room or outside wall the system runs to
- Any access panels or hatches you can see
- The postcode and the type of business
- When the site is open and when it’s quiet
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Danbury: your questions answered
Do you work at weekends in Danbury?
Yes, evening, overnight and weekend work is normal for us. It means the site in Danbury keeps running as normal. When you call us on 0345 646 2711 or email us, mention when the site is quiet.
Which environmental health team covers Danbury?
Kitchens in Danbury are inspected by Chelmsford council’s environmental health officers. A note of when the fan failed and when it was fixed shows the problem was dealt with.
Do you provide a certificate or report?
Yes. It’s your proof that the work was done: a written, dated record with pictures of what we did and anything we couldn’t access.
Does the law say we must follow TR19?
No. TR19® is BESA’s specification, not legislation. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
Do you work in Danbury?
Yes. Our technicians work in Danbury, as part of our area across London and the South East.
Will we have to shut during the visit?
Not typically. We need the work area to ourselves while we’re on site, so we book a time when it would be closed anyway.
Are you fully insured?
Yes. We carry full insurance, and we’ve been trading since 2009.
How far ahead should we book?
The more notice, the better, particularly for night and weekend visits. Quotes normally come back within one working day, and emergencies are covered by our 24/7 line.
Do you need extract fan repair in Danbury?
Some faults are in the controls rather than the fan. A failed speed controller or a wiring fault can stop a fan so we check the controls before blaming the motor.
Common reasons sites call us are:
- An extract fan that rattles or knocks
- A fan shaking on its mountings
- An old fan that needs replacing
- A squealing belt on start-up
If you run a school kitchen, at a school such as Danbury Park Community Primary School or nearby, a fan that is getting noisy is best repaired in the holidays before it fails in term.
Questions to ask before booking
- How areas they can’t reach will be recorded
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Exactly which parts of the system are covered
- Whether they’re fully insured
What happens if it’s left?
Weak extraction leaves heat, smoke and fumes in the kitchen. Staff work in hotter, steamier air and grease has more chance to settle on surfaces and in the duct. Booking now means the visit to Danbury is planned around you, not forced by a breakdown.
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
Why choose Duct Doctor in Danbury
- Out-of-hours work and a 24/7 emergency line

What the work involves, part by part
Belt-driven fans
A squeal when the fan starts is a classic belt symptom. Belts are checked for wear, tension and alignment and renew them where necessary.
Roof and wall-mounted fans
An external fan faces the weather as well as the grease. Corrosion of housings and fixings is common.

- A visit is booked, in the evening or overnight if that suits.
- We isolate the extract and open the fan housing.
- Bearings, drive, impeller, motor and mounts are inspected.
- We explain the options and quote a fixed price.
- We complete the work and check the fan runs smoothly.

Every one of them that cooks under a canopy depends on its extract fan to keep cooking. Environmental health officers from Chelmsford council inspect food businesses in Danbury. Ventilation is part of food hygiene law, which expects it to be suitable and sufficient. So a failed fan is worth fixing before the next service, not the next month. About 33 miles out from central London, Danbury is part of the South East area we work across. A survey and a fixed quote come first, then the visit at a time that suits you.
A fan that rarely runs, like one in a hall kitchen near Church of St John the Baptist or elsewhere in Danbury, can seize between uses.

Well-known places in the area include Baddow Hospital (3.5 miles west). The countryside around Danbury includes Danbury Ridge Nature Reserves.
Between visits
Think of this as the after-treatment advice, in brief:
- Keep the area around the fan controls clear
- Book regular TR19 cleaning, which includes the fan
- Save our number for the 24/7 emergency line
- Report new noises from the fan early
Clean filters help a repaired fan stay that way. Less grease on the impeller means less wear and fewer faults.
When filters block, the fan works harder. Keeping filters clean eases the strain and protects the motor.
