Do you need ventilation duct cleaning in Mark Hall North?
Refits and building work send dust into ventilation systems, particularly if it’s left running while work goes on. That dust can stay in the ducts long after the builders leave.
It’s time to book a visit if you see:
- Dirty diffusers dropping dust into rooms
- Toilet and washroom extracts full of fluff
- Systems with no record of inspection or cleaning
- Ductwork never cleaned since it was installed
Classrooms and halls at schools such as Tany's Dell Primary School and Nursery are easiest to work in when pupils are away.
What your quote should include
- If the quote is a fixed price or an estimate
- How areas they can’t reach will be recorded
- Proof of insurance

Ventilation duct cleaning in Mark Hall North
Every clean ends with a TR19® certificate and a photo report. The report lists what we cleaned, any sections not reached and a recommended next inspection, so you have it all on record. We are often asked to deal with ventilation full of debris from building work and systems missing access panels, across grilles and diffusers, supply ductwork and hospitals and care homes.
Smaller buildings around Mark Hall North often keep their ventilation units in a roof void or plant cupboard, where they’re easy to forget. Filters, coils and drain trays need attention whatever the size of the unit.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Part by part
Supply ductwork
Supply ductwork delivers conditioned air to each room. Fine dust that gets past the filters settles along the runs, and we remove it through access panels.
Schools and colleges
We plan the work around the school calendar and agree access with the site team.
Honest limits
Some problems need a different service or another trade:
- Leaks from roofs, pipes or walls into the ductwork
- Leaking or broken duct sections
- Design problems with the ductwork layout
If you’re not sure, just call 0345 646 2711 or use the quote form and we’ll give you a straight answer before booking.
Where we work
- Offices and schools
- Grilles and diffusers
- Supply ductwork
- Hospitals and care homes
- General extract ductwork
- Toilet extract systems
What your team can do, and what needs us
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Why deal with it now?
Landlords, tenants and auditors may want proof the ventilation is looked after. Having a recent certificate and photo report for a building in Mark Hall North answers the question. A visit arranged in advance is far less disruptive than a callout on a busy day.
You won’t find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we will explain what it covers.

How it 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 job takes a shift or two for a small system, longer for a whole building. Because the survey comes first, a visit to Mark Hall North can typically be finished without a second trip.
- We agree timings that suit the building, including evenings and weekends.
- We open the ductwork through its access panels.
- Before photos are taken and the ducts cleaned section by section.
- Grilles and diffusers are cleaned and refitted.
- We take after pictures and send the certificate and report.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Arrange a key holder or contact on site
- Let us know about parking and loading
Ask for a quote
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before any work starts.

What is TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t law, but it’s the benchmark.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. The report from each visit recommends the next date.
Are you accredited?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
Who is responsible for fire safety on the premises?
The Fire Safety Order 2005 calls them the responsible person: normally the employer or whoever controls the premises. In shared or managed buildings, a landlord, facilities manager or managing agent can share the duty.
Will you look at the ducts before quoting?
Yes. Every job is surveyed first, from photos, drawings or a site visit, then we give you a fixed quote.
Is a quote from photos possible?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote normally follows within one working day. Some sites still need a visit, and we’ll say so.
