For landlords and multi-site operators
Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
How we handle ventilation duct cleaning in Colindale
In a building in Colindale, the people inside spend hours breathing what the ventilation delivers. Keeping the ducts clean is a sensible part of looking after them, as much as clean filters and a well-kept AHU. The work covers general extract ductwork, hospitals and care homes and offices and schools, and the jobs we see most are toilet and washroom extracts full of fluff and ductwork with too few access panels to clean.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. For a building in Colindale, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
The paperwork matters as much as the work. You get a written report with photos after every visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

Busy, occupied buildings like these are where clean supply air matters most. Colindale’s nearest hospital, Edgware Community Hospital, is about 1.3 miles north-west.

What affects the quote in Colindale
The quote reflects the site in front of us. We take into account:
- A single visit or a regular plan
- Working hours and out-of-hours timing
- How big the system is
- How easy every part is to reach
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before we start.
Asking for a quote
There’s no need for technical detail. It helps if you can send:
- When the site is open and when it’s quiet
- The paperwork from the last visit, if you have it
- The roof, plant room or outside wall the system runs to
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Getting a quote does not take long. Call or email with a few details and you’ll typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Colindale: your questions answered
Does London parking affect a job in Colindale?
Tell us where a van can stop near your site in Colindale, and about any building rules on loading. If the building has a loading slot system, we will book into it.
Can you clean school ventilation in Colindale during the holidays?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 39 schools and colleges with food registrations within roughly a mile and a half of Colindale. You can give us a ring on 0345 646 2711, or email photos with the dates the site is empty.
How much notice do you need?
Earlier is better, particularly for night and weekend visits. Quotes usually come back within one working day, and there’s a 24/7 line for emergencies.
Is there a survey before the work?
Yes. Every job is surveyed first, from your pictures and details, or with a visit where needed. A fixed quote follows.
Are you insured?
Yes. We carry full insurance, and we’ve been trading since 2009.
Is TR19 a legal requirement?
No. The law sets the duty; TR19® is the benchmark used to show it’s met. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and without records, many insurers may refuse or reduce a claim.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before work begins, and anything we remove is contained. Before we leave, we tidy up and clean down.
Do you cover Colindale?
Yes. Our area takes in London and the counties of South East England, and that includes Colindale.
How the visit works
Everything the job needs comes with us, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. The visit takes anything from a single shift for a small office to a planned programme of nights for a large building. Loading bays, visitor permits and roof access are the first things we ask about for a site in Colindale.
- We look at the system and any earlier reports.
- We inspect the ducts at chosen points to see where cleaning is needed.
- The work area is protected and the system switched off.
- We clean the system and remove the debris from site.
- The report records what was cleaned, anything not reached and a next inspection date.
Getting ready for the visit
- Mention any sign-in, permit or induction we need
- Agree a time when the area can be out of use
- Allow time for equipment near the work to be turned off and cool down
How to get a quote
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.
Related advice
When it’s something else
In fairness, there are a few things this work won’t fix:
- Building management settings that run the plant
- Damaged ductwork beyond cleaning
- Cooking extract ducts, which are a separate specialist clean
Not sure which it is? You can give us a ring on 0345 646 2711, or send details by email and we will tell you honestly before you book.
Where we work
- Supply ductwork
- Hospitals and care homes
- Offices and schools
- General extract ductwork
- Toilet extract systems
- Grilles and diffusers
What happens if it’s left?
If a building in Colindale has just been refitted, now is the time to clean the ductwork. Otherwise the dust from the works comes out of the grilles once it’s switched back on. A building in Colindale may have flats or offices above and alongside, and a fault in the system can affect them too.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.

What your team can do, and what needs us
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, which is where we come in.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Common problems we fix in Colindale
Most ductwork is out of sight, so dust collects unseen. The grilles get a wipe, but what’s behind them doesn’t.
What we are most often called out for:
- Ducts that need a clean before handover
- Damp or stale smells from grilles
- Dirty diffusers dropping dust into rooms
- Blocked general extract ductwork
Wherever a school like Colindale Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
