Ventilation duct cleaning for kitchens and businesses in Dollis Hill

We always start by inspecting. We look inside the ductwork at set points and record what’s there, and cleaning is recommended where the inspection shows it’s due. That way the work matches the real condition. The work covers general extract ductwork, hospitals and care homes and toilet extract systems, and the jobs we see most are grilles and diffusers streaked with dirt and musty smells from the ventilation.

In London, plant rooms are often in basements or on roofs reached through occupied floors, so ventilation cleaning in Dollis Hill is normally planned out of hours. Loading and parking are planned with the building first.

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.

Ventilation in Dollis Hill buildings

The FSA’s food hygiene register lists about 40 schools, colleges and universities, about 37 care, childcare and hospital premises and about 6 hotels and guest houses with registered kitchens or food service across Dollis Hill and its immediate surroundings (about a mile and a half). Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. About under half a mile south of Dollis Hill is St Andrew's Hospital, the nearest hospital. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. Getting kit to a London plant room normally means lifts, stairs and an agreed loading slot.

Healthcare ventilation, from large hospitals like St Andrew's Hospital (about under half a mile south) to small clinics, depends on clean filters, coils and ducts. Classrooms and halls at schools such as Our Lady of Grace Catholic Junior School are easiest to work in when pupils are away.

The process

When we arrive, we check the system against the survey or the pictures you sent. 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 Dollis Hill saves time on the night.

  1. First the system is surveyed, on site or from photos and drawings.
  2. Ducts are inspected at access points and the condition recorded.
  3. We protect the rooms beneath and switch the system off.
  4. Dust and debris are removed from ducts, grilles and diffusers.
  5. A certificate and before and after photos follow, with anything not reached recorded.

Preparing for the visit

  • Mention any locked doors, roof access or ceiling voids
  • Tell us where we can park and unload
  • Make sure equipment near the work can be switched off and left to cool

Advice

Between visits

Aftercare is simple, and it makes the next visit easier:

  • Keep to the inspection interval in your report
  • Report leaks or damp near ceilings and risers
  • Keep vents and grilles clear of shelving and stock
  • Stick to the filter change schedule

Before any works, think about the ducts. Switch it off or cover the grilles while dusty work goes on.

Deal with condensation and leaks near ducts promptly, as moisture makes dust stick.

What happens if it’s left?

Facilities teams are regularly asked to show evidence of ventilation hygiene. A TR19® certificate and photo report from a recent clean give them that. A busy site in Dollis Hill builds up dirt and wear quickly, so putting it off makes the eventual job larger.

The cost depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before we start, so you know where you stand.

Staff cleaning versus specialist work

Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.

In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.

Different parts, different methods

Extract ductwork

Extract ducts take air out of toilets, washrooms and general areas. Lint, dust and fibres gather inside and restrict the flow over time.

Schools and colleges

Holidays and weekends are the natural time to clean school ventilation, with nobody in the classrooms.

When to call us in Dollis Hill

Many systems run for long hours, day after day, and every hour of running brings more dust with it. Heavier use means faster build-up.

The symptoms we are asked about most are:

  • Blocked general extract ductwork
  • Ventilation that needs a TR19® Air inspection
  • Dust marks around grilles and ceiling diffusers
  • Dusty supply ductwork that hasn’t been cleaned in years

If you run an office near Brent Cross West station, its supply ductwork can gather dust for years before anyone looks inside.

Questions to ask before you book

  • Whether a written report and pictures are included
  • What happens if part of the system can’t be accessed
  • Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
  • Whether the quote shows VAT

Landlords, agents and facilities managers

We also work for facilities teams across offices, schools and healthcare across Greater London. Work can be phased by floor, building or site to keep disruption down.

Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.

Common questions in Dollis Hill

Do you work overnight in Dollis Hill?

Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Dollis Hill needn’t be disturbed. Just call us on 0345 646 2711 or use the quote form with your opening times and we will plan around them.

Can a school’s ventilation in Dollis Hill be done out of term time?

Yes, holiday work suits schools best. The FSA’s register shows about 40 schools and colleges with food registrations within roughly a mile and a half of Dollis Hill. Tell us your holiday dates and we will book the visit for when the site is empty.

Can you quote from pictures?

Yes, if we can see what we need. If not, a site survey comes first, then a fixed quote.

What does TR19 Air cover?

It covers ventilation hygiene for supply and extract systems in offices, schools, hospitals and other buildings. Kitchen extract is covered separately, by TR19® Grease.

Do you have insurance?

Yes. We are fully insured, and we can share the details when you need them.

Do you provide a report?

Yes, a TR19® certificate and photos. It also notes unreached sections and a recommended next inspection.

Is TR19 cleaning required by law?

No, not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurance policies ask for proof of TR19® cleaning. The law behind it is the Fire Safety Order 2005 in England and Wales.

Which accreditations do you hold?

We’re 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.
