Ventilation Duct Cleaning in Northolt
Professional ventilation duct cleaning in and around Northolt, booked around your opening hours and finished with a written report and photos.
- Poor airflow from the vents
- Dust marks around grilles and ceiling diffusers
- Ductwork with too few access panels to clean
Why deal with it now?
Dust streaks around grilles and stale rooms suggest the ducts need looking at. Dealing with them now stops them getting worse. Leaving it on a busy London site only adds to the work.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. The price is fixed before we start.

Ventilation duct cleaning in Northolt
Every clean ends with a TR19® certificate and a photo report. It shows what was cleaned, anything we couldn’t reach and when the system should next be inspected, so you have it all on record. If you’re dealing with ductwork never cleaned since it was installed and extract ducts clogged with lint and dust, we can help.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. In a building in Northolt, dust and debris build up in the units and ductwork over time, which is what TR19® Air cleaning deals with.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

Northolt buildings and their air
The FSA’s food hygiene register lists about 40 schools, colleges and universities and about 51 care, childcare and hospital premises with registered kitchens or food service in and around Northolt, up to about a mile and a half out. Busy, occupied buildings like these are where clean supply air matters most. Ventilation cleaning in London buildings is normally planned for evenings or weekends. About 2 miles north-east of Northolt is Clementine Churchill Hospital, the nearest hospital. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital.
Clementine Churchill Hospital, about 2 miles north-east, is the nearest hospital to Northolt, and healthcare sites of every size need their supply air kept clean. For schools like Willow Tree Primary School, the holidays are the usual time to inspect and clean ventilation.
Northolt is about 2 miles south-west of Harrow, in Greater London. Whether your site is in the middle of Northolt or further out, ventilation duct cleaning is available to all kinds of commercial premises, from small sites to large estates. Northolt is one of 764 towns, villages and districts in Greater London we cover for commercial clients. For sites nearby, see our London page, about 12 miles away.

Part by part
Offices and retail
Refits in commercial space often leave construction dust in the ducts. A clean before handover is a sensible step.
Schools and colleges
Schools and colleges are easiest to clean during the holidays, with nobody in the classrooms.
When it’s something else
Before you book, it helps to know what’s not included:
- Design problems with the ductwork layout
- Leaking or broken duct sections
- Cooking extract ducts, which are a separate specialist clean
If you’re not sure, just call 0345 646 2711, or email photos and we will give you a straight answer.
What the work covers
- Toilet extract systems
- Supply ductwork
- Grilles and diffusers
- General extract ductwork
- Hospitals and care homes
- Offices and schools
Common problems we fix in Northolt
Most ductwork is out of sight, so nobody sees the build-up. Grilles may be wiped, but the ducts behind them rarely are.
If you notice any of these, it’s worth a diagnosis:
- Dusty supply ductwork that hasn’t been cleaned in years
- Ventilation full of debris from building work
- Systems missing access panels
- Damp or stale smells from grilles
If you manage shops or offices close to Northolt Park station, a TR19® Air inspection shows whether the ductwork needs cleaning.
Questions to ask before booking
- Whether VAT is included
- How areas they can’t reach will be recorded
- What hours they’ll be on site
- Whether the figure could change on the day
Common questions in Northolt
Can you clean school ventilation in Northolt during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 40 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Northolt. Send us your term dates when you call us on 0345 646 2711 or drop us a line, and we’ll fit the work in.
What do you need to know about parking in Northolt?
London parking can be tight, so details of loading bays and permits help. If the building has a loading slot system, we’ll book into it.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. The report from each visit recommends the next date.
What happens if you cannot reach some of it?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
How does TR19 Air differ from TR19 Grease?
It covers ventilation hygiene for supply and extract systems in offices, schools, hospitals and other buildings. Kitchen extract systems fall under TR19® Grease instead.
Do you clean grilles and diffusers?
Yes. Grilles and diffusers are cleaned as part of the job, so the room side is clean too.
Which accreditations do you hold?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.
How much time does a ventilation clean need?
It takes a weekend for a modest system, with large buildings phased floor by floor. The size of the system and the access make the biggest difference.
How the visit works
Your staff do not need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Before we leave, the area is tidied and the paperwork follows. In a London area like Northolt, parking, loading and building access are planned before the day of the work.
- 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.
- We take after photos and send the certificate and report.
Before we arrive
- Move anything stored near the system
- Find the previous report, if there is one
- Let us know when the site is closed or quiet
Getting a quote
To get a fixed quote, ring 0345 646 2711 or send us an email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You will usually have a quote within one working day.

How we price ventilation duct cleaning
We quote each job individually. These are the things that affect it:
- The condition we find in the survey
- Whether several sites go on one quote
- Where the site is and how we reach it
- Site requirements such as sign-in and permits
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 talk you through it.
Asking for a quote
To help us quote quickly, send us:
- Problems your staff have spotted
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- A few general shots of the system
- Your opening hours and when the area is out of use
To help us quote: the address, the type of site and when it’s open, pictures of the system and the last certificate or report, if there is one. Then phone us on 0345 646 2711 or send us an email.
