Leave it or put it right?
A clean system moves air more easily, which puts less load on the fans. Leaving them means the plant works harder for the same result. When a site near Northchurch shuts unexpectedly, the people who rely on it notice at once.
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will talk you through it.

Ventilation duct cleaning in Northchurch, done properly
Every ventilation system has ducts bringing air in and ducts taking it out. Dust and debris build up in both, some of which ends up back in the rooms. Our cleaning covers the ducts, grilles and diffusers, to TR19® Air. The work covers hospitals and care homes, grilles and diffusers and general extract ductwork, and people most often call us about systems with no record of inspection or cleaning and musty smells from the ventilation.
In a smaller place like Northchurch, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Even a small system collects dust in its ducts and filters.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

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 a single shift for a small office to a planned programme of nights for a large building. Tell us when your site near Northchurch is quiet and the visit will be booked for then.
- First we plan when the work can happen, often out of hours.
- Access panels are opened along each run.
- We photograph the ducts, then clean each section in turn.
- Grilles and diffusers are cleaned and refitted.
- After photos are taken and the certificate and report issued.
Getting ready for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us about site rules, permits or sign-in
- Tell us the best time to work, such as after service or at a weekend
Ask for a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.
Advice
Different parts, different methods
Hospitals and care homes
People in hospitals and care homes can be more vulnerable to poor air. Inspection-led cleaning under TR19® Air helps keep systems in good condition.
Supply ductwork
Anything in a supply duct can end up in the rooms it feeds. Cleaning it deals with the source.
Fixed quotes for ventilation duct cleaning in Northchurch
The survey tells us what the work involves. We look at:
- Site rules, permits and inductions
- Whether we need access equipment or extra panels
- Where the site is and how we reach it
- How many systems or sites are involved
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
What we need to know
A few details help us quote accurately. When you get in touch, it helps to send:
- The roof, plant room or outside wall the system runs to
- Close-ups of filters, grilles, hatches or access panels
- Your last certificate, test record or report
- A few general shots of the system
Want a quote for ventilation duct cleaning? Please ring 0345 646 2711, or email photos with a few details about the site. We will talk you through the work and give you a fixed quote before you commit to anything.
Looking after it afterwards
Here’s the after-treatment advice, in brief:
- Protect the system from construction dust
- Tell your facilities team about dirty diffusers
- Get leaks near ductwork fixed quickly
- Store cleaning certificates where auditors can find them
You get a TR19® certificate and a photo report after the clean. BESA advises keeping certificates in the maintenance log, with the date, location and technician on record.
Make sure there are enough access panels to inspect and clean the ducts. The worst build-up tends to be where no one can look.
Ventilation in Northchurch buildings
There are about 10 schools, colleges and universities and about 12 caring premises (care homes, nurseries and hospitals) on the FSA’s food hygiene register in and around Northchurch, up to about a mile and a half out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Northchurch’s nearest hospital, Hemel Hempstead Hospital, is about 5.2 miles east. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. At about 28 miles from central London, Northchurch sits well inside the area we cover. A survey and a fixed quote come first, then the visit at a time that suits you.
Healthcare ventilation, from large hospitals like Hemel Hempstead Hospital (about 5.2 miles east) to small clinics, depends on clean filters, coils and ducts. If you manage a school such as St Mary's CofE Primary School, ventilation cleaning is best booked for the holidays.

Multi-site and managed buildings
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.
Common questions in Northchurch
Can you work in Northchurch outside opening hours?
Yes. We work evenings, overnight and at weekends. The work in Northchurch can fit around your hours. When you ring 0345 646 2711, or send details by email, mention when the site is quiet.
Do you clean school ventilation in Northchurch in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 10 schools, colleges and universities with registered kitchens within about a mile and a half of Northchurch. Tell us your holiday dates and we will book the visit for when the site is empty.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line for anything that can’t wait until a planned visit. Ring any time and tell us what’s happened.
Is Northchurch in your area?

How does TR19 Air differ from TR19 Grease?
The two cover different systems: general ventilation for TR19® Air and kitchen extract for TR19® Grease. Under TR19® Air, inspection decides when cleaning is needed.
Is TR19 cleaning required by law?
No. The law sets the duty; TR19® is the benchmark used to show it’s met. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.
Which kinds of sites do you work on?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
Who is responsible for fire safety on the premises?
The law calls them the responsible person. It’s normally the employer, or whoever controls the building, and in shared buildings more than one person can have duties. Your lease and fire risk assessment should make it clear.
