Part by part
Offices and retail
Offices and shops tend to need the work done outside opening hours to keep the space open.
Hospitals and care homes
Patients and residents may be more sensitive to dust in the air. Inspection-led cleaning under TR19® Air helps keep systems in good condition.
Ventilation duct cleaning in Seven Sisters
Dust in ventilation ductwork isn’t only a cleanliness issue. It can restrict airflow, make the system work harder and send dust back into occupied rooms. Cleaning restores the clear airway the system was designed with. The work covers offices and schools, general extract ductwork and toilet extract systems, and people most often call us about toilet and washroom extracts full of fluff and stuffy rooms and stale air.
Many London buildings have had their ventilation extended and altered through several fit-outs, leaving sections that are hard to reach and seldom cleaned. In Seven Sisters, as elsewhere, cleaning starts with an inspection of what’s there.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

Seven Sisters buildings and their air
The FSA’s food hygiene register lists about 45 schools, colleges and universities and about 42 hospitals, care homes and childcare premises with registered kitchens or food service in and around Seven Sisters, up to about a mile and a half out. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. North Middlesex University Hospital is the nearest hospital, about 2.1 miles north of Seven Sisters. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital. London plant rooms are often on roofs or in basements reached through occupied floors.
If you run an office near Seven Sisters station, its supply ductwork can gather dust for years before anyone looks inside. If you manage a school such as Earlsmead Primary School, ventilation cleaning is best booked for the holidays.

FAQs for Seven Sisters
Can parking be tricky for a job in Seven Sisters?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Working overnight, as we often do in London, normally makes it simpler.
Do you work overnight in Seven Sisters?
Yes. We work evenings, overnight and at weekends. The work in Seven Sisters can fit around your hours. Just call us on 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you provide a report?
Yes, a TR19® certificate and photos. The report lists what was cleaned, anything not reached and the next inspection date.
How far ahead should we book?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Who is responsible for fire safety on the premises?
In the words of the Fire Safety Order 2005, it’s the responsible person. It’s normally the employer, or whoever controls the building, and in shared buildings more than one person can have duties. If you’re not sure, check your lease and fire risk assessment.
What happens if parts of the ductwork cannot be reached?
We clean what we can reach and note the rest. Fitting access panels tends to be the answer, and we can fit them.
Staff cleaning versus specialist work
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
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.
Fixed quotes for ventilation duct cleaning in Seven Sisters
There’s no set price list, because sites vary so much. The quote depends on:
- How easy every part is to reach
- The condition of the system
- One-off work versus a regular cycle
- Working hours and out-of-hours timing
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before we start.
What to send for a quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- How we’d reach plant on a roof or in a plant room
- Close-ups of filters, grilles, hatches or access panels
- Your last certificate, test record or report
- When the site is open and when it’s quiet
There’s no standard price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then send you a fixed quote. To get going, call us on 0345 646 2711, or email photos.
What happens on the day
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. After that, the work takes a weekend for a modest system, with large buildings phased floor by floor. A name and number for whoever controls access to the building in Seven Sisters saves time on the night.
- We start by looking at the layout of the ductwork and how it can be reached.
- We inspect inside the ductwork at set points and photograph it.
- The area below is protected and the system switched off.
- We clean the ductwork, grilles and diffusers through access panels.
- We issue a TR19® certificate and a photo report listing what was cleaned.
How to prepare
- Move anything stored near the system
- Plan for cooking equipment or plant to be off before we arrive
- Let us know about permits to work or site inductions
Getting a quote
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, you get a fixed price before work begins.

What we’re called out for in Seven Sisters
Refits and building work send dust into ventilation systems, especially when the system runs during the work. Plaster, wood and masonry dust can sit in the ducts for years.
It’s time to book a visit if you see:
- Ductwork that hasn’t been inspected
- Blocked general extract ductwork
- Supply ducts with years of dust inside
- Systems missing access panels
If you run a surgery, dental practice or care home near Seven Sisters, clean ventilation matters as much to you as to a hospital like North Middlesex University Hospital (about 2.1 miles north).
What your quote should include
- How areas they can’t reach will be recorded
- Whether a survey comes first
- Whether the figure could change on the day
- How they set the interval to the next visit
Keeping the system healthy
To keep the system working properly between visits:
- Don’t run the ventilation while builders are sanding or cutting
- Store cleaning certificates where auditors can find them
- Keep vents and grilles clear of shelving and stock
- Log every filter change
If there’s building work planned, protect the ventilation. Switch it off or cover the grilles while dusty work goes on.
Protect the system during building work by turning it off or covering the openings.
