How we handle ventilation duct cleaning in Northwood
In a building in Northwood, the people inside spend hours breathing what the ventilation delivers. Clean ducts are part of a healthy building, as much as clean filters and a well-kept AHU. The work covers hospitals and care homes, supply ductwork and grilles and diffusers, and common reasons people get in touch are extract ducts clogged with lint and dust and odours carried round the building by the ducts.
For a building near Northwood, the visit is planned around how it’s used, and the journey is planned ahead. The method does not change: inspect first, clean, then record what was done.
Duct Doctor has been trading since 2009, and 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.

What affects the cost of ventilation duct cleaning
A fixed price needs a few facts first. We look at:
- The size of the system
- The number of sites or systems
- Parking and loading at the site
- Site rules, permits and inductions
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before any work starts.
Helping us quote
We can often survey from pictures. The most useful are:
- Wide photos of the system and the area around it
- Any previous report or certificate
- The roof, plant room or outside wall the system runs to
- Your opening hours and when the area is out of use
There’s no standard price list, because no two systems are the same. We look at your system first, from pictures or on a visit, and then give you a fixed quote. To start, ring 0345 646 2711, or email photos.
Do you need ventilation duct cleaning in Northwood?
In a building in Northwood, the ventilation may run for long hours every day, and every hour of running brings more dust with it. Heavier use means faster build-up.
Keep an eye out for any of the following:
- Poor airflow from the vents
- Construction dust left in ducts after a refit
- Ventilation that needs a TR19® Air inspection
- Dirty diffusers dropping dust into rooms
If you manage a school such as Dame Janet Primary Academy, ventilation cleaning is best booked for the holidays.

Northwood buildings and their air
There are about 31 schools, colleges and universities, about 24 care, childcare and hospital premises and about 3 hotels and B&Bs on the FSA’s food hygiene register within 1.5 miles or so of the middle of Northwood. Busy, occupied buildings like these are where clean supply air matters most. Ramsgate General Hospital is the nearest hospital, about 1.6 miles south of Northwood. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Healthcare buildings such as Ramsgate General Hospital, about 1.6 miles south, depend on their ventilation; if you manage a surgery, clinic or care home near Northwood, yours matters too. If you run an office near Ramsgate station, its supply ductwork can gather dust for years before anyone looks inside.

The process
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes anything from a single shift for a small office to a planned programme of nights for a large building. Evenings, weekends or a closed day all work for a site in a place like Northwood.
- First we plan when the work can happen, often out of hours.
- We open the ductwork through its access panels.
- We photograph the ducts, then clean each section in turn.
- We clean the grilles and diffusers and put them back.
- After pictures are taken and the certificate and report issued.
Before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms
- Clear the space around the work
- Mention any parking or loading restrictions

Common questions in Northwood
Can you clean school ventilation in Northwood during the holidays?
Yes. The holidays are the usual time for school work. Around Northwood, the Food Standards Agency lists about 31 schools and colleges with registered kitchens within a mile and a half or so. You can call us on 0345 646 2711, or send details by email with the dates the site is empty.
Can the work in Northwood be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Northwood needn’t be disturbed. When you ring 0345 646 2711, or send details by email, mention when the site is quiet.
How does TR19 Air differ from TR19 Grease?
TR19® Air applies to the general ventilation in buildings like offices, schools and hospitals. Kitchen extract is covered separately, by TR19® Grease.
How do you keep the site clean during the work?
Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
What happens to the waste?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.
Are you insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
Will you clean the vents in the rooms?
Yes. Where they can be removed, they’re taken down, cleaned and refitted. Fixed ones are cleaned in place.
Do you cover Northwood?
Yes. Our area takes in London and the counties of South East England, and that includes Northwood.
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. Inside the ducts, risers and fan is specialist work, which is where we come in.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.

Hospitals and care homes
In care settings, keeping dust contained is a priority. We protect the work area and take everything away.
Schools and colleges
Busy classrooms send a lot of dust and fibre into extract ducts. Regular inspection keeps on top of it.
When something else is needed
Before booking, it helps to know what’s not included:
- Ducts that are damaged, corroded or leaking and need replacing
- Controls and BMS faults that affect the system
- Condensation caused by the building rather than the ducts
If in doubt, give us a ring on 0345 646 2711 or send us an email and we’ll say what we think before you book.
What the work covers
- Supply ductwork
- Hospitals and care homes
- Offices and schools
- Toilet extract systems
- General extract ductwork
- Grilles and diffusers
Looking after it afterwards
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Log every filter change
- Make sure nothing is stacked against extract grilles
- Switch the ventilation off or cover grilles during dusty building work
- Report leaks or damp near ceilings and risers
Change filters on schedule so the clean ducts stay clean. Overdue filters let dust straight back in.
Fit access panels where the ductwork cannot be reached. The worst build-up tends to be where no one can look.
