How we handle extract fan repair in Kemprow
Working on a fan in Kemprow means switching the extract off first, so the job is fitted around the kitchen’s hours. Evenings, overnight and weekends are all possible, and a fan that dies mid-service can go straight to our 24/7 line. If you have a fan that won’t start at all and a humming noise from the fan motor, we can help, from belts and pulleys, bearings and roof and wall fans onwards.
In a small place like Kemprow, fans are often on an outside wall or roof, open to wind and rain. Weather and grease together wear out motors and bearings.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

When to call us in Kemprow
Some grease always slips past the filters and reaches the fan. Deposits gather on the blades, never quite evenly, so the fan runs out of balance and the noise follows.
Any of these means the system needs a check-up:
- A dead fan motor
- Weak extraction and a smoky kitchen
- A fan worn beyond sensible repair
- A fan that whines, hums or grinds
If you manage a school such as Fair Field Junior School and the kitchen fan is getting louder, the next break is the time to deal with it.
Questions to ask before booking
- Whether they’re fully insured
- Exactly which parts of the system are covered
- Whether the quote is based on a survey or photos
- What hours they’ll be on site
Extract fans in Kemprow
Look up Kemprow on the FSA’s food hygiene register and you’ll find about 26 cafés, restaurants and staff canteens and about 8 takeaways and sandwich shops within roughly a mile and a half of the centre of Kemprow. A kitchen with a dead extract fan gets hot and smoky fast, and kitchens like these feel it at once. We cover Kemprow, about 16 miles from central London, as part of our work across London and the South East. Visits are booked around your hours, evenings and weekends included. Kitchens in Kemprow get their food hygiene inspections from Hertsmere council. Food hygiene rules expect food premises to have suitable and sufficient ventilation. So a failed fan is worth fixing before the next service, not the next month.

Looking after it afterwards
After the visit, a few habits help the work last:
- Make sure every filter is in place and clean
- Keep all filters fitted while cooking
- Avoid lowering the speed to quieten a fault
- Book regular TR19 cleaning, which includes the fan
Once we are done, the extract is back in service. We leave the area tidy and explain anything you need to know.
Regular TR19 cleaning includes the extract fan. A clean impeller stays in balance, so planned cleaning helps the fan last.

The process
Each visit runs to the same pattern: sheeting and protection first, make the system safe, do the work, clear away and hand over the paperwork. On site, the work takes anything from an hour or two to a full visit, depending on the fault. For a village or hamlet like Kemprow, 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.
- We complete the work and check the fan runs smoothly.
Preparing for the visit
- Move anything stored near the system
- Let us know how we reach the system, including roofs, risers and plant rooms
- Mention any sign-in, permit or induction we need

How the job changes from site to site
Impellers and housings
The impeller is the bladed wheel that moves the air. Grease on it throws it out of balance and make it shake.
Fan controls
Speed controllers and isolators sit between the supply and the fan. When they fail, the fan may not start or may run at the wrong speed.
Leave it or put it right?
In Kemprow, as elsewhere, an extract fan may well sit outside on a wall or roof, so its noise does not stay in the kitchen. Dealing with the fault brings the noise back down before neighbours notice. It’s simpler to plan the work at Kemprow now than to arrange it in a hurry later.
You won’t find a price list here, because each job is priced on what it involves. For a fixed quote, call 0345 646 2711 or use the quote form, and we will explain what it covers.

For landlords and multi-site operators
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
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’re happy to quote for all of it.
Your questions about extract fan repair in Kemprow
What if my kitchen extract fan stops in Kemprow at night?
Our emergency line runs 24/7, and Kemprow 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.
Can the work in Kemprow 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. Your opening times are the first thing we ask for.
Are you fully insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
What will a fan repair or replacement cost?
Every fan job is priced once we know the fault. A belt and a new fan are very different jobs, so call 0345 646 2711, or email photos and we’ll arrange a diagnosis.
What do you do with what you remove?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
Is TR19 a legal requirement?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person has to manage fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.
What should go in our maintenance log?
Anything that proves the system is maintained: reports, certificates, photos and your own cleaning or check logs. One maintenance log per site keeps it simple.
What accreditations do you have?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We have been trading since 2009 and we are fully insured.
