Crook Log ventilation duct cleaning
We cover Crook Log for ventilation duct cleaning. Out-of-hours visits, a fixed quote and a written report with pictures as standard.
- Dusty supply ductwork that hasn’t been cleaned in years
- Blocked general extract ductwork
- Damp or stale smells from grilles
The process
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before any work starts, and the area around the work is covered and protected. On site, it takes a weekend for a modest system, with large buildings phased floor by floor. Expect the work in Crook Log to happen after your last customer leaves, not during trading.
- First the system is surveyed, on site or from photos and drawings.
- Inspection comes next, with photos of the inside of the ducts.
- The area below is protected and the system switched off.
- We clean the ductwork, grilles and diffusers through access panels.
- You get a TR19® certificate and photo report, with any unreached sections noted.
Preparing for the visit
- Tell us the best time to work, such as after service or at a weekend
- Tell us about site rules, permits or sign-in
- Name a contact who can let us in at the agreed time
Ask for a quote
To help us quote: the address, the type of site and when it’s open, pictures of the system and the last certificate or report, if there is one. Then ring 0345 646 2711 or drop us a line.

How we handle ventilation duct cleaning in Crook Log
Ductwork is reached through access panels along each run. Where there aren’t enough panels to reach every section, we note the uncleaned parts in the report, and new access panels can be installed so they’re covered next time. If you have odours carried round the building by the ducts and rooms that feel airless when the system runs, we can put it right.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. For a building in Crook Log, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

What a clean won’t put right
We won’t sell you work that does not address the problem, so here are the limits:
- A system that is not designed to move enough air
- Leaks from roofs, pipes or walls into the ductwork
- Ducts that are damaged, corroded or leaking and need replacing
If you are not sure, just give us a ring on 0345 646 2711 or drop us a line and we’ll give you a straight answer before booking.

When to call us in Crook Log
In a building in Crook Log, the ventilation may run for long hours every day, and every hour moves more dust through the ducts. Heavier use means faster build-up.
What we’re most often called out for:
- Construction dust left in ducts after a refit
- Blocked general extract ductwork
- Dusty supply ductwork that hasn’t been cleaned in years
- Dirty diffusers dropping dust into rooms
Workplaces around Bexleyheath station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.
Before booking anyone
- Whether the whole system is included, or only the parts that are easy to reach
- Whether they’re fully insured
- Whether a written report and pictures are included
- What happens if part of the system cannot be accessed
Looking after it afterwards
So the system stays in good health:
- Flag any dust coming out of the vents
- Wipe grilles and diffusers during routine cleaning
- Diary the next TR19® Air inspection
- Keep vents and grilles clear of shelving and stock
The report lists the sections we cleaned and any we couldn’t reach, with pictures before and after. If access panels are needed, we will say where.
Fix leaks and damp near the ductwork quickly, as wet dust is much harder to clean.
FAQs for Crook Log
Is parking a problem for work in Crook Log?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Much of our London work is done overnight, which helps.
Can ventilation in schools around Crook Log be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. Around Crook Log, the Food Standards Agency lists about 31 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you ring 0345 646 2711 or drop us a line, and we’ll fit the work in.
Will we have to shut during the visit?
Usually not. Out-of-hours visits keep the disruption down. Bigger sites can be done in stages to keep things running.
What should I send you?
Some pictures and a quick description of the system, with the address and opening hours. We will ask for anything else we need.
What happens if parts of the ductwork can’t be reached?
Accessible sections are cleaned and the others recorded. Fitting access panels tends to be the answer, and we can quote for them.
What types of premises do you cover?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
What does ventilation duct cleaning cost?
We do not publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before we start.
Do you work with multi-site operators?
Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.
What your team can do, and what needs us
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
