How we handle ventilation duct cleaning in Coombe
Dust in ventilation ductwork isn’t only a cleanliness issue. It slows the air, strains the fans and can be blown back out of the grilles. A clean puts the system back as it should be. The work covers toilet extract systems, general extract ductwork and grilles and diffusers, and common reasons people get in touch are ventilation full of debris from building work and grilles and diffusers streaked with dirt.
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 Coombe, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
Think of the report as the system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Coombe questions
Can parking be tricky for a job in Coombe?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Night visits tend to make loading easier on London streets.
Do you clean school ventilation in Coombe in the holidays?
Yes, holiday work suits schools best. The FSA’s register shows about 22 schools and colleges with food registrations within roughly a mile and a half of Coombe. Just ring 0345 646 2711, or email photos with your term dates and we will plan around them.
How often should ventilation ductwork be cleaned?
Inspection should decide it, in line with TR19® Air. Busy or sensitive buildings may need it more often.
Do you offer maintenance contracts?
Yes, of course. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
What do you need from me for a quote?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. After that, simply ring 0345 646 2711, or email photos.
How long does ventilation cleaning take?
Expect it to take from one overnight visit to a phased programme over several weeks. The size of the system and the access make the biggest difference.
Do you survey before quoting?
Yes. For many sites, pictures and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
What staff can safely do
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Ventilation in Coombe buildings
Going by the FSA’s register, there are about 22 schools, colleges and universities and about 35 care, childcare and hospital premises serving food within roughly a mile and a half of the centre of Coombe. Busy, occupied buildings like these are where clean supply air matters most. Coombe’s nearest hospital, Kingston Hospital, is about 0.8 miles west. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital. In London, ventilation plant is often on the roof or below ground, so the work is typically done out of hours.
School buildings such as Coombe Hill Junior School are normally done in the holidays, so classrooms aren’t disturbed.

What affects the cost of ventilation duct cleaning
Your quote is based on your site. We consider:
- Access, including roofs, risers and ceiling voids
- The condition we find in the survey
- Any permits to work or inductions
- Whether several sites go on one quote
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and why the quote is fixed before work begins.
What we need to know
Photos and a few facts are often enough to price the work. Useful things to send:
- Detail shots of panels, filters and grilles
- When the site is open and when it’s quiet
- Wide pictures of the system and the area around it
- Any symptoms, from odd noises to smells or leaks
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
What ventilation duct cleaning can’t fix
We will always give you a straight diagnosis, so here’s what ventilation duct cleaning will not do:
- Design problems with the ductwork layout
- Controls and BMS faults that affect the system
- Cooking extract ducts, which are a separate specialist clean
If in doubt, ring 0345 646 2711 or email us and we will say what we think before you book.
What the work covers
- Offices and schools
- Toilet extract systems
- General extract ductwork
- Supply ductwork
- Hospitals and care homes
- Grilles and diffusers
Common problems we fix in Coombe
Planned maintenance tends to focus on fans and filters, not the ducts. A building in Coombe can have well-serviced plant and dirty ductwork at the same time.
These are the problems we see most often:
- Damp or stale smells from grilles
- Blocked general extract ductwork
- Ventilation full of debris from building work
- Systems with no record of inspection or cleaning
If you run a surgery, dental practice or care home near Coombe, clean ventilation matters as much to you as to a hospital like Kingston Hospital (about 0.8 miles west).
Questions to ask before you book
- Proof of accreditation you can verify
- Whether a written report and pictures are included
- Exactly which parts of the system are covered
- Whether they’re fully insured
How the job changes from site to site
Grilles and diffusers
Where they come out, grilles are taken down and cleaned, then refitted.
Supply ductwork
Supply ducts carry air from the AHU into the rooms. Fine dust that gets past the filters settles along the runs, and we remove it through access panels.
What happens if it’s left?
A clean system moves air more easily, which takes strain off the fans. Dirty ducts make the whole system work harder. A booked night’s work in Coombe costs you no trading time; an unplanned closure does.
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.

How the visit works
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes anything from a single shift for a small office to a planned programme of nights for a large building. Expect the work in Coombe to happen after your last customer leaves, not during trading.
- We look at the system and any earlier reports.
- Inspection points are chosen and the ducts examined.
- We cover the area below and turn off the system.
- Ducts, grilles and diffusers are cleaned and the debris taken away.
- The report records what was cleaned, anything not reached and a next inspection date.
Getting ready for the visit
- Tell us where we can park and unload
- Arrange a key holder or contact on site
- Tell us the best time to work, such as after service or at a weekend
Getting a quote
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before any work starts.
