- Systems missing access panels
- Rooms that feel airless when the system runs
- Supply ducts with years of dust inside
Keeping the system healthy
No system stays clean for ever, but care slows the build-up. Our tips:
- Keep the TR19 certificate and photo report in the maintenance log
- Diary the next TR19® Air inspection
- Protect the system from construction dust
- Watch for water stains around grilles
The report lists the sections we cleaned and any we couldn’t reach, backed up by before and after photos. We’ll suggest where new access panels would help.
Good filter maintenance protects the ductwork. Overdue or badly fitted filters let dust into the supply ducts.
Ventilation duct cleaning in Letchmore Heath
Everyone in the building breathes the air the ventilation brings in. Clean ducts are part of a healthy building, as much as clean filters and a well-kept AHU. Common call-outs are for toilet and washroom extracts full of fluff and ducts that need a clean before handover, across offices and schools, toilet extract systems and hospitals and care homes.
Work in a small place like Letchmore Heath starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Each visit ends with a written report and photos, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

How the job changes from site to site
Hospitals and care homes

Grilles and diffusers
Grilles and diffusers that are designed to come out are removed for cleaning, then refitted.
Honest limits
Not every problem is solved by ventilation duct cleaning, and we’ll tell you before any work starts. It will not put right:
- Design problems with the ductwork layout
- Condensation caused by the building rather than the ducts
- Problems with how the system is controlled
If you are not sure, just call 0345 646 2711, or email photos and we will give you a straight answer before booking.

Fixed quotes for ventilation duct cleaning in Letchmore Heath
Sites vary more than people expect. What affects the quote:

- The condition of the system
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.
What we need to know
Photos and a few facts are often enough to price the work. Useful things to send:
- Any access panels or hatches you can see
- The times we could work without disrupting the site
- Photos showing the whole system and its surroundings
- The paperwork from the last visit, if you have it

Why act early in Letchmore Heath
In healthcare, care and education settings, ventilation cleaning is hard to put off. Good indoor air starts with a clean system. Rural sites can’t always move to another kitchen or room when something fails.
The cost depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before work begins, so you know where you stand.

Yes, out-of-term visits are normal for schools. The FSA’s register shows about 12 schools and colleges with food registrations within roughly a mile and a half of Letchmore Heath. Booking early in the term gives the best choice of holiday dates.
Can the work in Letchmore Heath be done at night or at weekends?

Do you offer maintenance contracts?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.
How long will the duct cleaning take?
Expect it to take a weekend for a modest system, with large buildings phased floor by floor. How much ductwork there is and how easily it’s reached decide the rest.
Which accreditations do you hold?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.
What is TR19® Air?
TR19® Air is the part of BESA’s TR19® that covers general supply and extract ventilation, beyond the kitchen. It works on inspection and risk, while TR19® Grease covers kitchen extract systems.
Do you clean grilles and diffusers?
Yes. Grilles and diffusers are cleaned as part of the job, so the room side is clean too.
Is Letchmore Heath in your area?
Yes. We work in Letchmore Heath and the rest of Hertfordshire, within our South East and London area. To book, give us a ring on 0345 646 2711 or email us.

Advice
Do you need ventilation duct cleaning in Letchmore Heath?
Even good filters let some dust through, and that fine dust settles along the supply ducts. Extract ducts collect whatever the rooms give off: dust, fibres and lint.
Most sites get in touch after spotting one of these:
- Ventilation full of debris from building work
- Dust marks around grilles and ceiling diffusers
- Dusty supply ductwork that hasn’t been cleaned in years
- Damp or stale smells from grilles
Healthcare ventilation, from large hospitals like Shenley Hospital (about 2.6 miles north-east) to small clinics, depends on clean filters, coils and ducts.
What to look for in a quote

- When they can work, and whether that is outside your opening hours
