Ventilation duct cleaning in Todd's Green
Extract ducts from toilets, changing rooms and general areas collect dust and lint. Supply ducts carry anything the filters miss. We clean both, keeping the work tidy and the building protected. We’re often asked to deal with extract ducts clogged with lint and dust and ventilation full of debris from building work, across offices and schools, general extract ductwork and toilet extract systems.
Work in a small place like Todd's Green starts with agreeing access and timings.
It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Questions from Todd's Green
Is Todd's Green within the area you cover?
Yes, Todd's Green is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
Do you do school ventilation cleaning in Todd's Green in the summer holidays?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 10 schools and colleges with food registrations within roughly a mile and a half of Todd's Green. Booking early in the term gives the best choice of holiday dates.
What about areas you cannot get to?
We record them on the report, with photos where possible, and we tell you what would make it reachable, for example new access panels.
How often should ventilation ductwork be cleaned?
Under TR19® Air, the answer comes from inspecting the ducts. Busy or sensitive buildings may need it more often.
What if there aren’t enough access panels?
Nothing is hidden: any section we couldn’t get into is listed. We can install panels to open those sections up.
How long does ventilation cleaning take?
Typically, the work takes a weekend for a modest system, with large buildings phased floor by floor. Bigger sites are split into stages, to fit around the building.
Where does the waste go?
We take it away at the end of the visit. While we work, it’s kept contained so the area stays clean.
Can you quote from pictures?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
Signs you need ventilation duct cleaning in Todd's Green
Many systems run for long hours, day after day, and every hour of running brings more dust with it. The busier the building, the faster it builds up.
Keep an eye out for these warning signs:
- Ductwork that hasn’t been inspected
- Ducts that need a clean before handover
- Damp or stale smells from grilles
- Supply ducts with years of dust inside
Wherever a school like The John Henry Newman School has ducted ventilation, a half-term visit keeps the work out of lesson time.
Before you book anyone
- Proof of insurance
- When they can work, and whether that is outside your opening hours
- What’s included in the scope, part by part
- What happens if part of the system can’t be accessed
How the job changes from site to site
Offices and retail
Multi-let buildings may share ductwork between tenants. We plan access with the managing agent.
Supply ductwork
Supply runs are inspected at set points first to see where cleaning is needed.

Between visits
Here’s the after-treatment advice, in brief:
- Don’t block grilles with furniture or storage
- Report leaks or damp near ceilings and risers
- Report dust blowing from grilles right away
- Switch the ventilation off or cover grilles during dusty building work
A TR19® certificate and photo report follow every clean. BESA advises keeping certificates in the maintenance log, with the date, location and technician on record.
Don’t let construction dust into the ventilation by switching it off or covering the grilles.
What affects the cost of ventilation duct cleaning
Every site gets its own quote. This is what makes a difference:
- The number of sites or systems
- How easy every part is to reach
- Travel, parking and unloading
- One-off work versus a regular cycle
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re unsure, call us on 0345 646 2711 or email us and we will give you an honest view and a fixed quote.
What to send for a quote
When you call or email, it’s useful to have:
- The paperwork from the last visit, if you have it
- The roof, plant room or outside wall the system runs to
- When the site is open and when it’s quiet
- A few general shots of the system
For a fixed quote, ring 0345 646 2711 or send us an email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You will typically have a quote within one working day.
Honest limits
An honest diagnosis matters more to us than a booking, so here’s what ventilation duct cleaning won’t do:
- Leaks from roofs, pipes or walls into the ductwork
- Building management settings that run the plant
- Ducts that are damaged, corroded or leaking and need replacing
If in doubt, call us on 0345 646 2711 or drop us a line and we’ll say what we think.

Staff cleaning versus specialist work
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
